Answer:
A) 4.3 m/s
Explanation:
M = mass of the cannon = 1200 kg
m = mass of the cannonball = 100 kg
v = speed of the cannonball after the fire = 52 m/s
V = speed of cannon after fire
Since the cannon and cannonball were at rest before fire, total initial momentum will be taken as 0
Using conservation of momentum
0 = m v - M V
M V = m v
inserting the values
(1200) V = (100) (52)
V = 4.3 m/s
The gravitational potential energy becomes work driving the pipe

A force will be exerted on a conductor and the conductor remains uncharged.
<u>Explanation:</u>
- When a charged particle is brought close to associate dead conducting object, a force is occurring on the conducting object to maneuver the lepton to the alternative of the conductor.
- There will be a separation of charge on the conducting object and also the charge is neutral. This is often thanks to the presence of charged insulating object close to it. Thus the conducting object is dead.
- When we brought concerning the insulating object, there'll be a force of attraction between the dead conducting objects and also the insulating object. Thus, there's a force occurring on the conducting object.
This is in the thermosphere which is at an altitude of 85-520km
Answer:
Explanation:
By the definition of centripetal acceleration ,
where ,
