A30 cm wrench is used to loosen a bolt with a force applied 0.30 mm from the bolt. it takes 60 n to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 30 degree angle from perpendicular?

The applied force is 69.28 N.

Explanation:

Given that,

Distance = 30 cm

Force = 60 N

Distance = 0.30 m

We need to calculate the torque to loosen the bolt

Using formula of torque

Where, F = force

d = distance

Put the value into the formula

We need to calculate the force

To get the same torque with a force applied at 30 degree

Using formula of torque again

Hence, The applied force is 69.28 N.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
