An object in circular motion has velocity that is constantly changing.

The direction of the acceleration is from the object toward the center of the  circular path the object is following.

What is the relation between force and acceleration​
Galina-37 [17]

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

It is easier to roll a stone up a sloping road than to lift it vertical upwards because.
kvasek [131]

Answer:

Because the force one needs to apply is reduced.

Explanation:

  • Work can be expressed in terms of force and distance as follows,

                        Work = Force × distance

  • To be more precise, the selection of these two parameters should be in a manner that the distance is what the line of action of the force traces.
  • It is obvious that for a given amount of work when one parameter is changed the other changes to counteract the change of the first one.
  • Imagine the situation shown in the attached figure. The amount of work that needs to be done during the lifting of the mass to a height of \small h vertically is E = mg\times h = mgh.
  • On the slope, however, one needs to push the object an L distance up to get the object to that h height ultimately.
  • The work he does on the slope is mgh = F\times L and sinceL > h , F < mg.
  • The force that needs to be applied is less than that applied in the vertical lift. Hence it feels easier.             #SPJ4

HELP PLEASE!!!
Leya [2.2K]

For the first one 320

second

1200W

Data

R = 12 Ω ∆V = 120V I =? P =?

Solution:

According to Ohm’s law,

∆V = I R

I = ∆V / R  

= 120 / 12  

= 10 A

Power P = I ∆V  

= 10 x 120  

= 1200 W

Third

∆V = 120 V P = 60 W I =? R =?

Use the formula, P = I ∆V

I = P / ∆V = 60 / 120 = 0.5 A

∆V = I R

R = ∆V / I = 120 / 0.5 = 240 Ω
