Answer:

Explanation:

In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.

Kinetic energy is 1/2mv^2

m being mass

v being velocity

The kinetic energy of an object is directly proportional to the speed of the object. If we double the speed of the object then the kinetic energy of the object will increase by a factor of four or four times.

Kinetic energy is the energy which is present in an object which has because of its motion. If we want to accelerate an object, then we must apply the force of some magnitude. Applying a force, requires us to do some work. After the work has been done, then the energy has been transferred to the object, and the object will be moving with a new constant speed.

Kinetic energy is directly proportional to the mass of the object and to the square of its speed or velocity:

K.E. = 1/2 m × v²

If the mass has the units of kilograms and the velocity of meters per second, then the kinetic energy has units of kilograms-meters squared per second squared.

Answer:

frying an egg is conduction because the pan is touching the stove and the pan is touching the eggs

Explanation:

Answer:

1) Changing value

2) The velocity is decreasing for upward motion and increasing for downward motion due to gravitational force

Explanation:

1) A trajectory is the motion of an object which is being acted upon by specified forces. The flight path of an object in projectile motion is its trajectory

During the course of a trajectory, the vertical component of the velocity, [tex]v_y[/tex], is a changing value

2) The vertical component of the velocity first decreases, during the upward motion, according to the following equation;

[tex]v_y[/tex] = [tex]u_y[/tex] - g·t

Where;

[tex]v_y[/tex] = The vertical component of the velocity after a given time, t

[tex]u_y[/tex] = The initial vertical velocity

t = The time of motion of the trajectory

g = The acceleration due to gravity ≈ 9.8 m/s²

When the vertical velocity of the object decreases to zero, which is the point at which the object reaches the maximum height of its motion, the direction of the vertical motion of the object reverses, and object begins to accelerate and increase its velocity downwards according to the following equation;

[tex]v_y[/tex] = [tex]u_y[/tex] + g·t

Therefore, the velocity of the object is decreasing on its way up, and then increasing on its way down.

Answer:

Explanation:

Since the forces are only in the x-direction, you could just add the two forces. The West is to the left, so it would be -25N with the negative sign indicating direction. The East is to the right, so that would be +50N.

50 + (-25) = 25N to the right or the positive i-hat direction

Answer:

changes in displacement

Explanation:

Answer:

2.86m/s²

Explanation:

[tex]\boxed{average \: acceleration = \frac{change \: in \: velocity}{time} }[/tex]

Car's average acceleration

[tex] = \frac{20 - 0}{7} \\ = 2.86 \: m/ {s}^{2} \: (3 \: s.f.)[/tex]

The reason why the change in velocity over time is average acceleration is because we are finding the total difference in velocity and dividing it against the total duration. This means that the acceleration of the car can vary throughout the 7 seconds (may not be a constant acceleration) but on average, the car's acceleration 2.86m/s², to 3 significant figures.

Change in velocity

= v -v₀

= final velocity -initial velocity

Since the car is at rest at the beginning, the initial velocity (v₀) is 0m/s.

Answer:

Average acceleration

As we are already knowing that

[tex] \sf Acceleration_{Avg} [/tex] = TA/T

TA = Total acceleration

T = Time

A = 20/7

A = 2.85 m/s²

The correct sequence of steps for lighting a Bunsen burner would be C, D, B, A, therefore the correct answer is option D.

Thermal energy sometimes referred to as heat energy, may be described as the type of energy in which heat is transmitted from one body to another body as a result of their molecular motions.

The following would be the proper procedure for lighting a Bunsen burner:

Link the gas outlet and the burner hose.

The gas output valve should be opened.

Open the Bunsen burner's base-mounted gas adjustment valve.

The Bunsen burner's barrel should be covered with the spark.

Thus, the right response is option D since the proper stages to ignite a Bunsen burner are C, D, B, and A.

Kinetic energy of an object is the energy that it possesses due to its motion.

Answer:

When an unbalanced force acts on an object, the motion of the object is changed. If the object is at rest, the force makes it move. If the object is in motion, the force changes its velocity. Any change in velocity is acceleration

Answer:

O Distance​

Explanation:

With the given information, it is possible to find the distance of the car has traveled on the home from school.

This is possible because distance is the length of path a body covers.

From the given values:

  Distance  = 5208  - 5200  = 8miles

It is not possible to find the displacement because no direction was given.

Also velocity is not possible since the time frame of travel was not state.

Answer: a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton's second law of motion, net force is mass times acceleration: net . For uniform circular motion, the acceleration is the centripetal acceleration

Explanation:

Centripetal force is the force which causes the change in direction of velocity towards the center of the circular motion of an object.

Centripetal force is any kind of force which causes a change in the direction of velocity of an object which is moving towards the center of the circular motion. The component of this force which is perpendicular to the velocity of the object is the part which results in the centripetal force.

The force of gravity which acts up on a satellite in the orbit is an example of a centripetal force. The friction of the tires of a car which makes a turn that is similarly provides centripetal force on the car.
