Which best explains what will happen if Sharilyn unscrews a bolt with a short handled wrench?

Physics

bezimeni [28]3 years ago

The last choice is the correct one.  This is the reason that wrenches
have long handles. 

If the bolt is really stuck or rusted on there, a person who is careful
and knows what he's doing will sometimes put one end of a 2-ft pipe
over the wrench-handle, and then push on the other end of the pipe. 
Pushing on a point that's farther away from the bolt always makes it
easier to unscrew.

A horizontal force of 400 N is exerted on a 2.0-kg ball as it rotates (at
frutty [35]

Answer:

the speed of the ball is 10 m/s

Explanation:

Given;

magnitude of exerted force, F = 400 N

mass of the ball, m = 2 kg

radius of the circle, r = 0.5

The speed of the ball is calculated by applying centripetal force formula;

F = \frac{mv^2}{r} \\\\v^2 = \frac{Fr}{m}\\\\v = \sqrt{\frac{Fr}{m}}\\\\ v = \sqrt{\frac{400*0.5}{2}}\\\\v = 10 \ m/s

Therefore, the speed of the ball is 10 m/s

The atoms in a sidewalk on a hot summer day are vibrating _____ the atoms in the sidewalk on a freezing day in winter.
Karolina [17]

Answer:

(A) more rapidly than

Explanation:

With higher temperatures, object's molecules (and atoms) have higher kinetic energy which is due to faster "jiggling" (vibrations). On a hot day these vibrations in the material the sidewalk is made of are more rapid than on a cold day, just as their temperatures differ.

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O
Ulleksa [173]

Answer:

  • The nuclear force is attractive and not repulsive.
  • The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

  • Nuclear force is the strongest existing force in the nature.
  • It has the shortest range.
  • Its main function is to hold the subatomic particles together in nature.
  • The nuclear force is created  by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.
  • At about 1 femtometer the nuclear force is very strongly attractive in nature but at distance greater than 2.5 femtometer it fades away.
  • The force becomes repulsive in nature at distance less than 0.7 femtometer.
  • This force holds the likely charged protons together in the nucleus.

Compare 2,500 centimeters to 25 decimeters. How do each of these values compare to a meter, and which represents a longer length
Rom4ik [11]
2500 centimeters is 25 meters. 25 decimeters is 2.5 meters. 2500 centimeters is 10 times longer than 25 decimeters.

When a car is coasting downhill, how are its potential and kinetic energies changing?
olasank [31]

When a car is coasting downhill, the kinetic and potential energies are increasing and decreasing respectively.

<h3>What are kinetic and potential energy?</h3>

Kinetic energy is the energy possessed by an object because of its motion, equal to one half the mass of the body times the square of its speed.

Potential energy, on the other hand, is the energy possessed by an object because of its position (in a gravitational or electric field), or its condition (as a stretched or compressed spring, as a chemical reactant, or by having rest mass).

According to this question, a car going downhill will begin to speed because there is lesser friction. This suggests that the kinetic energy increases while the potential energy decreases.
