How is the acceleration of an object in uniform circular motion constant?

1 answer:

3 0

Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. ... The net force acting upon such an object is directed towards the center of the circle.

Transcranial magnetic stimulation (TMS) is a noninvasive method for studying brain function, and possibly for treatment as well.

Answer:

525 V

Explanation:

A = Area = $1.75\times 10^{-2}\ m^2$

$\dfrac{dB}{dt}$ = Rate of change of magnetic field = $3\times 10^4\ T/s$ (assumed)

Induced electromotive force is given by

$E=A\dfrac{dB}{dt}\\\Rightarrow E=1.75\times 10^{-2}\times 3\times 10^{4}\\\Rightarrow E=525\ V$

The induced electromotive force is 525 V

If a shuttle is orbiting a planet at a distance of 40 miles from the center of the planet, and is traveling at a rate of 500 mil

lawyer [7]

Answer:

Time taken, t = 30.15 minutes

Explanation:

It is given that,

Distance from the center of planet, r = 40 miles

Speed of the shuttle, v = 500 miles per hour

Let t is the time taken by it to complete one full orbit. The displacement of the shuttle is,

$d=2\pi r$

$d=2\pi \times 40$

d = 251.32 miles

Now time can be calculated using the expression for the velocity as :

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

$t=\dfrac{251.32\ miles}{500\ miles\ per\ hour}$

t = 0.50264 hours

t = 30.15 minutes

So, the shuttle will take 30.15 minutes to complete one full orbit. Hence, this is the required solution.

Two people are pushing a couch from opposite sides. one person pushing to the right with a force of 3 N. the other person pushes

skelet666 [1.2K]

letter a because 4N to the left +3N to the right = 4N left minus 3N left as you change the direction of 3N then you also change the plus into minus. the direction will always favour to which of the direction is bigger
