The force is 50 N
Hope it will help :)
Answer:
[tex]\boxed {\boxed {\sf 50 \ Newtons }}[/tex]
Explanation:
Force can be found using the following formula.
[tex]F=m*a[/tex]
where F is the force, m is the mass, and a is the acceleration.
1. Define Values
We know the acceleration of the bowling ball is 10 m/s² and the mass is 5 kilograms.
[tex]a= 10 \ m/s^2 \\m= 5 \ kg[/tex]
2. Calculate Force
Substitute the values into the formula.
[tex]F= 5 \ kg * 10 \ m/s^2[/tex]
Multiply.
[tex]F= 50 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 Newton. Our answer of 50 kg*m/s² is equal to 50 N[tex]F=50 \ N[/tex]
The force causing the ball to fall is 50 Newtons

While eating lunch high up in a skyscraper, two construction workers calculate their gravitational potential
energies, and find them to be equal. If the lighter construction worker has a mass of 90kg, and the other worker
is twice as high up in the skyscraper, what is the mass of the other worker?
Answer:
The mass of the other worker is 45 kg
Explanation:
The given parameters are;
The gravitational potential energy of one construction worker = The gravitational potential energy of the other construction worker
The mass of the lighter construction worker, m₁ = 90 kg
The height level of the lighter construction worker's location = h₁
The height level of the other construction worker's location = h₂ = 2·h₁
The gravitational potential energy, P.E., is given as follows;
P.E. = m·g·h
Where;
m = The mass of the object at height
g = The acceleration due to gravity
h = The height at which is located
Let P.E.₁ represent the gravitational potential energy of one construction worker and let P.E.₂ represent the gravitational potential energy of the other construction worker
We have;
P.E.₁ = P.E.₂
Therefore;
m₁·g·h₁ = m₂·g·h₂
h₂ = 2·h₁
We have;
m₁·g·h₁ = m₂·g·2·h₁
m₁ = 2·m₂
90 kg = 2 × m₂
m₂ = (90 kg)/2 = 45 kg
The mass of the other construction worker is 45 kg.

a sealed bottle of water was taken from a refrigerator and left in a warm kitchen. explain in the terms of its molecules what happened to the thermal energy and temperature of the water in a few minutes
Answer:
Explanation:
The sealed bottle serves as an open system for the water molecules, thus heat energy can be exchanged with its surroundings. When the bottle is placed in a warm environment, there would be a gradual increase in the thermal energy of the molecules of water due to a change in the temperature of its surroundings.
Thus, the molecules of water closer to the boundary of the bottle absorbs heat, becomes lighter and changes position. This gradual process continues until all molecules attains an average temperature which equals that of the surroundings of the bottle.
Therefore, both the thermal energy and temperature of the water increases.

A coastline on Earth experiences tides according to the graph below.
A graph showing a high tide at approximately 12 hours and 24 hours with a low tide occurring 6 hours before each high tide.
What type of tide is cycling in this location?
AWNSER CHOICES:
A: Diurnal tides
B: Mixed dinural tides
C: Mixed semidiurnal tides
D: Semidiurnal tides
If I can figure out how to mark brainliest I will if the awnser provided is correct
Answer:
Most coastal areas, with some exceptions, experience two high tides and two low tides every lunar day (Ross, D.A., 1995). Almost everyone is familiar with the concept of a 24-hour solar day, which is the time that it takes for a specific site on the Earth to rotate from an exact point under the sun to the same point under the sun. Similarly, a lunar day is the time it takes for a specific site on the Earth to rotate from an exact point under the moon to the same point under the moon. Unlike a solar day, however, a lunar day is 24 hours and 50 minutes. The lunar day is 50 minutes longer than a solar day because the moon revolves around the Earth in the same direction that the Earth rotates around its axis. So, it takes the Earth an extra 50 minutes to “catch up” to the moon (Sumich, J.L., 1996; Thurman, H.V., 1994).
the answer is C
Mixed semidiurnal tides is the type of wave that coastline on Earth experiences.

In 5 seconds a car moving in a straight line increases its speed
from 50 km/h to 65 km/h, while a truck goes from rest to 15
km/h in a straight line. Which undergoes greater aceleration?
What is the acceleration of each vehicle
Explanation:
because the track and the car moved same speed there their acceleration will be the same
a) The acceleration of the car and the truck are equal since for both vehicle is 15km/h and the time taken for both vehicle is also the same 5s.
b) The acceleration of the each vehicle is 0.83334 m/s².
Given data in the question is,
Time taken for both car and truck, t = 5 seconds
Initial velocity of car, Uc =50km/hr =13.8889 m/s
Final velocity of car, Vc = 65 km/hr = 18.0556 m/s
Since the truck starts from rest,
Initial velocity of the truck Ut =0
Final velocity of the truck Vt = 15 km/hr = 4.16667 m/s
What is acceleration?Acceleration can be defined as the rate of change of velocity.
a) The acceleration of the car and the truck are equal since for both vehicle is 15 km/h time taken for both vehicle is also the same 5s.
b) The acceleration of each vehicle is to determine.
To determine the acceleration for car and the truck , we use the first equation of motion:
v = u+ at
Where v is the final velocity,
u is the initial velocity,
a is the acceleration,
t is the time.
Now, For the car,
13.8889 m/s = 18.0556 m/s + ( a × 5)
a = [tex]\frac{ 18.0556 m/s- 13.8889 m/s}{5}[/tex]
a = [tex]\frac{4.1667}{5}[/tex]
a = 0.83334 m/s².
Hence, the acceleration of the car is 0.83334 m/s².
For the truck,
4.16667 m/s = 0 + (a× 5)
a = [tex]\frac{0-4.16667}{5}\\[/tex]
a = [tex]\frac{4.16667}{5}[/tex]
a = 0.83334 m/s²
Hence, the acceleration of the bicycle is 0.83334 m/s².

12.Two masses are arranged as shown on a ramp that makes an angle of 36° with the horizontal. Mass m1 is twice mass m2
. What is the minimum coefficient of static friction required between mass m1 and the ramp to ensure equilibrium?
Force M2 exerts on tension T
T = M2 g
T = M1 g sin theta - M1 g u cos theta
Note that M1 g is exerted down the plane while the frictional force opposes this motion and will be directed in the opposite direction of M1 g
M2 g = M1 g sin theta - u M1 g cos theta
1 = 2 sin 36 - u 2 cos 36
.5 = sin 36 - u cos 36
u = (sin 36 - .5) / cos 36 = .108
Any friction less that this will result in sliding
"1.7456" would be the minimum coefficient of static friction required.
Given:
Angle,
[tex]\Theta = 30^{\circ}[/tex]Mass,
[tex]m_2 =2 m_1[/tex]To keep the system in equilibrium forces acting on mass "[tex]m_1[/tex]" must balance forces acting on "[tex]m_2[/tex]".
That's,
→ [tex]Forces \ on \ m_1 \ downward \ along \ ramp = Forces \ on \ m_2 \ downwards[/tex]
or,
→ [tex]m_1 g Sin \Theta + \mu_s m_1 g Cos \Theta =m_2 g[/tex]
Thus,
→ [tex]\mu_s = \frac{m_2 g - m_1 g Sin \Theta}{m_1 g Cos \Theta}[/tex]
[tex]= \frac{m_2-m_1 Sin \ 36^{\circ}}{m_1 Cos \Theta}[/tex]
hence,
→ [tex]\mu_s = \frac{2 m_1 - m_1 Sin \ 36^{\circ}}{m_1 Cos \ 36^{\circ}}[/tex]
[tex]= 1.7456[/tex]

A dog sled was moving to the right on an icy surface with low friction, when the connecting rope between the sled and the dogs broke. What happens to the motion of the sled? *
Answer:
The sled will slow down in speed
Explanation:
According to Newton's first law of motion, a body will continue to be at rest or uniform motion unless acted upon by an external force.
In this situation, once the connecting rope between the sled and the dogs breaks, the motion of the sled will reduce because it is no longer connected to the dog that is providing the motion, hence the source of motion is no longer connected to the sled

When the motion energy of an object changes, energy is being transferred. How do you know that's true?
Answer: The statement when the motion energy of an object changes, energy is being transferred is true.
Explanation:
Motion energy is also called mechanical energy and it is the summation of kinetic energy and potential energy stored in an object required for work.
As kinetic energy is the energy acquired due to motion of an object and potential energy is the energy acquired by an object due to its position.
For example, when a moving ball strikes another ball causing it to move then energy is being transferred from one ball to another.
Therefore, the statement when the motion energy of an object changes, energy is being transferred is true.
Godric and Savos are a few meters apart, at one end of the football field. Peter is at the other end of the field. Godric and Savos starts moving towards Peter at a speed of 4m/s. From Savos point of view how is Godric moving?
Answer:
From Savos point of view, Gadros appear not to be moving
Explanation:
The given parameters are;
The distance between Godric and Savos = A few meters
The location of Godric and Savos = One end of the field
The location pf Peter = The other end pf the field
The speed with which Godric and Savos are moving towards Peter = 4 m/s
Let the positive x-direction be the direction in which Godric and Savos are moving
Therefore;
The speed and direction with which Godric is moving = The speed and direction with which Savos is moving = 4·i m/s
From Savos point of view, the relative speed with which Godric is moving = (The speed and direction in which Godric is moving) - (The speed and direction in which Savos is moving) = 4·i m/s - 4·i m/s = 0 m/s
Therefore, from Savos point of view, the relative speed with which Godric is moving = 0 m/s or Gadros appears stationary or not to moving.

An object is place 30.5 cm from a convex lens that has a focal length of 8.0cm.where is the image ?
Answer:
Image is between F and 2F. And the exact location is:
q = 10.84 cm
Explanation:
The convex lens form different kinds of images with different sizes and locations, for the different positions of an object. In this case, the object is placed 30.5 cm from the convex lens with a focal length of 8 cm. This means that it is the case of the object placed beyond 2F. In this case, the image formed has the following characteristics:
1. Image is real.
2. Image is inverted
3. Image is diminished
4. Image is located between F and 2F
For exact location we use the thin lens formula:
[tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]
where,
f = focal length = 8 cm
p = object distance = 30.5 cm
q = image distance = ?
Therefore,
[tex]\frac{1}{8\ cm} = \frac{1}{30.5\ cm} + \frac{1}{q} \\\frac{1}{8\ cm} - \frac{1}{30.5\ cm} = \frac{1}{q}[/tex]
q = 10.84 cm

At which position would a cat on Earth have least amount of pull due to gravity?
in a cat bed on the ground
on a second floor window sill
in a plane flying above Earth
Answer:
in a plane flying above Earth
Explanation:
Gravity is the force that draws objects toward center of the earth. If you throw an object up on the earth's surface, you will notice that it will fall back to the ground due to the earth's gravitational pull on the object.
However, the further one goes from the earth's surface, the lesser the gravitational pull. Therefore the cat will experience less gravitational pull in an airplane flying at a higher altitude.
