Answer:
Time constant of RC circuit is 0.105 seconds.
Explanation:
It is given that,
Resistance,
Capacitance,
We need to find the expected time constant for this RC circuit. It can be calculated as :
So, the time constant for this RC circuit is 0.105 seconds. Hence, this is the required solution.
Answer:
a) 0.658 seconds
b) 0.96 inches
Explanation:
Time taken by the ball to reach the highest point is 0.14 seconds
The highest point reached by the snowball above its release point is 0.315 ft
Total height the snowball will fall is 4+0.315 = 4.315 ft
The snowball will reach the bank at 0.14+0.518 = 0.658 seconds after it has been thrown
The snowball goes 0.5-0.42 = 0.08 ft = 0.96 inches
Answer:
The drill's angular displacement during that time interval is 24.17 rad.
Explanation:
Given;
initial angular velocity of the electric drill, = 5.21 rad/s
angular acceleration of the electric drill, α = 0.311 rad/s²
time of motion of the electric drill, t = 4.13 s
The angular displacement of the electric drill at the given time interval is calculated as;
Therefore, the drill's angular displacement during that time interval is 24.17 rad.
