A force of 314 N is exerted on the end of a wrench in order to apply a torque of 40.0 N·m to a bolt head. The point of application of the force is 21.5 cm from the center of the bolt. What angle does the force make with respect to the wrench handle?

36.16 degree

Explanation:

We are given that

Force,F=314 N

Torque=T=40 Nm

Distance,r=21.5 cm=

1 m=100 cm

We have to find the angle made by force with respect to the wrench handle.

We know that

Torque,T=

Using the formula

the first step is making objective observations.

they have to be based on a certain event and can be confirmed by others if it is right or not.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
