Wouldn’t it be 1. resistance is high compared to the voltage and with less resistance, higher current
Explanation:
a)
θ = 4.91 + 9.7t + 2.06t² when t = 0
θ = 4.91 rad
θ = 4.91 + 9.7t + 2.06t²
ω = dθ/dt = 9.7 + 2.06t, when t =0
ω = dθ/dt = 9.7 + 0
ω = 9.7 rad/s
α = d²θ/dt² = 2.06
α= 2.06 rad/s²
b) please use same method above for t = 2.94 s
<u>Answer</u>
Yes, the car reaches the door before the gate closes.
<u>Explanation</u>
The time taken by the car to reach at the door.
Time = distance / time
= 22/13
= 1.6923 seconds
Time taken by the door to close up to the height of the car.
Distance the door has to move to prevent the car from escaping = 9.1.4 = 7.6 m
From newton's 2nd law of motion;
s = ut + 1/2 gt²
7.6 = 0.6t + 1/2 × 10t²
7.6 = 0.6t + 5t²
50t² + 6t - 76 = 0
Solving this quadrilatic equation,
t = 28.537 seconds
Answer: Yes, the car reaches the door before the gate closes.
Answer:
True - Archimedes Principle states that the buoyant force on an object is equal to the weight of the liquid displaced.
Answer:
16kg*m/s west
Explanation:
P=M*V
Momentum= Mass time velocity, plug it into the formula,
M is 4 and V is 4, 4*4=16, and since the object is moving west its going to be west.
basically saying in simpler terms,
16=4*4
