Answer: gravity, circuits
Explanation:
Answer:
Explanation:
Given
diameter of spacecraft 
radius 
Force of gravity
=mg
where m =mass of object
g=acceleration due to gravity on earth
Suppose v is the speed at which spacecraft is rotating so a net centripetal acceleration is acting on spacecraft which is given by






Answer:
Final velocity at the top of the ramp is 6.58m/s
Explanation
Check the attachment
Answer:
18.1347 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a

Total height the ball falls is 2.4619+14.3 = 16.7619 m

The speed at which the stone reaches the ground is 18.1347 m/s
Answer:

Explanation:
The change in electrical potential energy of a charged particle moving through a potential difference is given by

where
q is the magnitude of the charge of the particle
is the potential difference
In this problem:
- the charge of the particle is 3.00 elementary charges, so

- the potential difference is

So, the change in electrical potential energy is
