Hello!
Use <u>ohm law:</u>
I = V / R
Replacing:
I = 100 V / 20 O
I = 5 A
The current is <u>5 amperes.</u>
Answer:
0.9Ns
Explanation:
Impulse formula is expressed as;
Impulse = Ft = m(v-u)
Impulse = m(v-u)
m is the mass of football = 0.45kg
v is the final velocity = 22m/s
u is the initial velocity = 0m/s
Impulse = 0.45(22-0)
Impulse = 0.45 * 22
Impulse = 0.9Ns
Hence the magnitude of the impulse imparted to the receiver by the ball is 0.9Ns
Answer:
of the velocity of a full size plane in the air
