Which describes acceleration involving only a change in direction?

Physics
1 answer:
Viefleur [7K]4 years ago
6 0
If we consider any system moving with u<span>niform circular motion we can notice that the MAGNITUDE of the accelaration remains constant. However,  there is a change in the direction of the acceleration at every instant of time .

 As the object moves through the circle the acceleration changes its direction always pointing to the center of the circle.</span>

if you put something like apiece of cardboard between a magnet and a iron nail, the magnet still holds the nail. how?
AlekseyPX
Magnetic fields can go through some materials (like cardboard). Electric fields can also do that. Electromagnetic waves can do that. It’s not at all unusual because magnetic fields are not made up of particles so they can go through materials.

Margy is trying to improve her cardio endurance by performing an exercise in which she alternates walking and running 100.0 m ea
madreJ [45]
In order to answer this exercise you need to use the formulas

 S = Vo*t + (1/2)*a*t^2

Vf = Vo + at

The data will be given as

Vf = final velocity = ?

Vo = initial velocity = 1.4 m/s

a = acceleration = 0.20 m/s^2

s = displacement = 100m

And now you do the following:

100 = 1.4t + (1/2)*0.2*t^2

t = 25.388s

and

Vf = 1.4 + 0.2(25.388)

Vf = 6.5 m/s

So the answer you are looking for is 6.5 m/s

1) How does the frequency of sound affect the speed of sound?
Travka [436]

Changing frequency of sound does not change the speed of the sound.

Explanation:

  • Speed of the sound gets altered when the sound travels from one medium to another.
  • Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
  • Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
