Select the statement that best describes how the forces relate. A. All forces begin equally and become varied. B. The object on

which they are acting and the distance to that object determines the amount of forcee Weak nuclear and differentbecause magnetic forces are associated with unmoving charges, and weak nuclear foraremagnetic forces are associated with moving charges. C. All forces are related to the mass of the object on which they are acting. The larger the mass, the weaker the forces become. D. Electromagnetic and Gravitational forces are most alike because their range is not limited.

Electromagnetic and Gravitational forces are most alike because their range is not limited. 
forsale [732]4 years ago

Explanation:

The statement that describes how the forces relate is "Electromagnetic and Gravitational forces are most alike because their range is not limited".

Both electromagnetic and gravitational force follows inverse square rule. The electrostatic force is acting between charged particles and gravitational force acts between two masses.

Electrostatic force is F_e=k\dfrac{q_1q_2}{r^2}

Where, q₁ and q₂ = charges and r = distance

Gravitational force is F_g=k\dfrac{m_1m_2}{r^2}

Where, m₁ and m₂ = masses and r = distance

Both these forces  are long range means at infinity force never becomes zero.

Hence, the correct options is "Electromagnetic and Gravitational forces are most alike because their range is not limited".

The mechanical advantage of the lever is 3 and the right option is A.) 3.

<h3>What is mechanical advantage?</h3>

Mechanical advantage can be defined as the ratio of load to effort in a machine.

To calculate the mechanical advantage of the lever, we use the formula below.

Formula

  • M.A = y/x................ Equation 1

Where:

  • M.A = mechanical advantage of the lever
  • y = distance moved by effort (input arm)
  • x = distance moved by load (output arm)

From the question,

Given:

  • y = 3 m
  • x = 1 m

Substitute these values into equation 1

  • M.A = 3/1
  • M.A = 3.

Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.

If you push a crate across a factory floor at constant speed in a constant direction, what is the magnitude of the force of fric
poizon [28]

Answer:

The magnitude of the force of friction equals the magnitude of my push

Explanation:

Since the crate moves at a constant speed, there is no net acceleration and thus, my push is balanced by the frictional force on the crate. So, the magnitude of the force of friction equals the magnitude of my push.

Let F = push and f = frictional force and f' = net force

F - f = f' since the crate moves at constant speed, acceleration is zero and thus f' = ma = m (0) = 0

So, F - f = 0

Thus, F = f

So, the magnitude of the force of friction equals the magnitude of my push.

Digiron [165]

Answer:

The answer is B- it decreases from 40 J to 37 J.

Explanation:

Because as you see it was at 8 then it went down 3 just like how it started at 40 and went down 3 to 37.

A disc on a frictionless axle, starting from rest (0 rpm) can spin up to a rotation rate of 3820 rpm in a period of 2 seconds. (
Eddi Din [679]

Answer:

1000 Nm

2000 Nm

1.00007 seconds

Explanation:

I = Moment of inertia = 5 kgm²

\alpha = Angular acceleration

\omega_f = Final angular velocity

\omega_i = Initial angular velocity

t = Time taken

Torque is given by

\tau=I\alpha\\\Rightarrow \tau=5\times 200\\\Rightarrow \tau=1000\ Nm

The torque of the disc would be 1000 Nm

If \alpha=400\ rad/s^2

\tau=I\alpha\\\Rightarrow \tau=5\times 400\\\Rightarrow \tau=2000\ Nm

The torque of the disc would be 2000 Nm

From equation of rotational motion

\omega_f=\omega_i+\alpha t\\\Rightarrow t=\frac{\omega_f-\omega_i}{\alpha}\\\Rightarrow t=\frac{3820\times \frac{2\pi}{60}-0}{400}\\\Rightarrow t=1.00007\ s

It would take 1.00007 seconds to reach 3820 rpm
