Answer:
We have that Assuming No air resistance,the initial horizontal velocity of the cannonball is
From the question we are told that
A cannonball is shot from a cannon at a launch angle of 35 and an initial velocity of 147 m/s
Generally the equation for the horizontal velocity is mathematically given as
Therefore
Therefore Assuming No air resistance,the initial horizontal velocity of the cannonball is For more information on this visit

Answer:
B, D,E,F
Explanation:
Situations from the list in which mechanical energy is conserved.
Whenever there is friction there is always some loss of energy in the process and hence energy cannot be conserved.
- The Moon orbiting the Earth (Total energy is remains the same)
- An ice skater gliding along the ice
( smooth surface no friction loss)
- A ball sliding down a friction less hill ( again friction less process)
- A child swinging on a friction less swing, ignoring air resistance
Answer:
The magnetic field is upwards.
Explanation:
You have to use "Right-hand rule", but for electrons, the direction of the magnetic force should be reversed.
