1. the insect
because of how fast the car is going and how small they are
There is a force of 2 Newtons to the RIGHT, and a force of 4 Newtons to the LEFT. The Net Force would be 4 Newtons RIGHT minus 2 Newtons LEFT =
B. 2 Newtons to the left
Answer:
873 MW
Explanation:
Find the voltage in the primary circuit.
Vp / Vs = Np / Ns
Vp / 198 kV = 500 / 1700
Vp = 58.2 kV
Calculate the power.
P = VI
P = (58.2 kV) (15.0 kA)
P = 873 MW
Answer:
H=10.93 m
Explanation:
Given that
h'= 0.75 m
r= 1.5 m
ω = 3 rev/s
ω = 3 ₓ 2 π rad/s
ω = 6 π rad/s
Speed of the ball when it releases from the rope,V.
V= ω x r
V= 6 π x 0.75
V=14.13 m/s
We know that acceleration due to gravity always in downward direction.
The final speed will be zero
h = 10.18 m
So the height from the ground,H = h' + h
H= 10.18 + 0.75 m =10.93 m
H=10.93 m
