Answer:

   F = 93.25 lb

Explanation:

To solve this problem let's use the rotational equilibrium condition

         Σ τ = 0

let's fix a reference system located at the end of the table, the position of Juan and assume the counterclockwise turns as positive

        F_jhon 0 - w l / 2 - W (l-4.9) + F l = 0

        F = w l / 2 + W (l -4.9) / l

where w is the weight of the table and W the weight of the box

let's calculate

        F = (44.5 12/2 + 120 (12- 4.9)) / 12

        F = 93.25 lb

Answer:

Yes cause he walks 6.7 miles

The displacement vector of the man is equal to 17.41 miles in the Northeast direction.

The displacement of an object can be defined as the shortest distance between two points. The displacement can be described as a vector quantity because contains both direction and magnitude. The displacement can be positive (+ve), negative, or zero and can change with time.

The distance is the total path traveled and is a scalar quantity as it has only magnitude, and no direction. The distance is always positive (+ve), it can never be equal to zero.

Given, a man moves 2.6 miles along AB in the East and then 6.7 miles North along BC.

The displacement (AC) of the man can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (2.6)² + (6.7)²

AC² = 6.76 +44.89

AC = 17.41 miles

Therefore, the displacement vector of the man is 17.41 miles.

Add Ff from Fa

Explanation:

Fnet = sum of all force

horizontal net force = Ff + Fa

Answer:

A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulae, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, by ratios to the key element.

Answer:

From the ohms law, V=IR

Where V is Voltage

I is current

R is Resistance

:. I=V/R

I=12/6

I=2A

The current will be 2A

Explanation:the flow of charges per unit time is inversely proportional to the resistance, when resistance increase, the current flow decreases to appreciate the change.

Answer:

The current is 1 A

Explanation:

Current in a Series Connection

When two or more elements are connected in series, all of them have the same current, and the sum of their individual voltages is the total voltage applied to the circuit.

According to Ohm's law:

V=R.I

Where V is the voltage, R is the resistance and I is the current of a circuit.

We have a voltage of V=1.5 V + 1.5 V = 3 V and a resistance of R=3 ohms.

We can calculate the current by solving for I:

[tex]\displaystyle I=\frac{V}{R}=\frac{3}{3}=1\ A[/tex]

The current is 1 A

Answer:

a=4m/s2

Explanation:

Vi= 20m/s

S=150 m

t= 5 sec

a=?

using 2nd equation of motion;

S= Vit+0.5at^{2}

putting values

150= (20)(5)+0.5(a)([tex]5^{2}[/tex])

150-100= 12.5a

50/12.5 =a

4m/s2=a

Answer:

220km

Explanation:

Given parameters:

Distance traveled from Minnehaha to Nut Plains  = 11km

Distance traveled to Dover  = 209km

Unknown:

The distance the soft drink distributor traveled  = ?

Solution:

To solve this problem, we  must understand that distance is the total length of path covered in a journey.

 So;

     Distance  = 209km + 11km  = 220km

The soft drink distributor covered 220km

Answer:

60 to 80%

Explanation:

For maximum benefit, the heart rates during exercise regimes should be between 60 to 80% of an individual's maximum heart rate.

The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;

  220 - 40 = 180 beats per minute.

Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.

Answer:

r = 1.3m

Explanation:

The moment of inertia of a solid sphere can be expressed using the formula;

I = ⅖ mr²

Where;

I = moment (kgm²)

m = mass of the sphere (kg)

r = rotational radius of the sphere (m)

Based on the provided information in this question, I = 1.52 kgm², m = 2.25 kg, r = ?

1.52 = ⅖ × 2.25 × r²

1.52 = 0.4 × 2.25 × r²

1.52 = 0.9 × r²

1.52 = 0.9r²

r² = 1.52/0.9

r² = 1.688

r² = 1.69

r = √1.69

r = 1.3m

Answer:

D. Increasing resistance and keeping current from A P E X :))

Explanation:

The decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.

Voltage is the force applied by the power source to charged electrons in a conducting loop, allowing them to perform tasks such as igniting light.

As we know according to the ohm's law:

V = IR

Where 'V' is the volatge,

'I' is the current.

'R' is the resistance.

If we assume 'I' is constant

Then V∝R

As the resistance increases the voltage increases and vice versa.

Thus, the decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.

Answer:

v = 88.89 [m/s]

Explanation:

To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.

We must make up the following equation:

[tex]F*t = m*v[/tex]

where:

F = force applied = 4000 [N]

t = time = 0.001 [s]

m = mass = 0.045 [kg]

v = velocity [m/s]

Answer:

The air will stop pouring out of the hole in the tire when the pressure inside the tire is equal to atmospheric pressure

Explanation:

The question relates to equilibrium conditions

The given parameters are;

The condition of the pressure of the air in the tire, P = Pressurized, P > Atmospheric pressure

The pressurized air is let out of the tire through a hole made by a nail

Therefore;

When the pressure inside the tire is more than atmospheric pressure, the force per unit area of the air from the side of the hole inside the tire is more than the force per unit area acting in the opposite direction and the pressure forces the air out of the tire

Therefore, the air continues pouring out of the hole in the tire up to the point when the pressure inside the tire becomes equal to atmospheric pressure, at which point the force per unit area of the air on either side of the hole are equal.

D. the distance and direction to the water fountain

Explanation:

To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.

This quantity is known as the displacement.

Answer:

The slope of an x vs. t graph represents instantaneous velocity. As we can see, the slope of this graph is not constant- it is changing. This means that the instantaneous velocity is also changing. Therefore, the object is accelerating.
