They will be on the move the whole time
Answer:
I = 3.028 A
Explanation:
given,
Number of turns in the coil = N = 1400
Area of DC motor per turn = 1.1 × 10⁻² m²
Maximum torque in motor = 8.4 N.m
Magnetic field in the coil = 0.18 T
Current in the coil = ?
using formula for toque in the magnetic field
τ = N A B I
8.4 = 1400 x 1.1 × 10⁻² x 0.18 x I
I = 3.028 A
Current in the coil will be equal to I = 3.028 A
Answer:
s = 400 ft
The maximum height reached by the ball is 400 ft
Explanation:
Given;
Initial vertical velocity v = 160 ft/s
Height function s = 160t - 16t^2 ......1
The maximum height is reached when the change in height with respect to time is zero.
ds/dt = 0
Differentiating the height function;
ds/dt = 160 - 32t = 0
160 - 32t = 0
Solving for t;
32t = 160
t = 160/32
t = 5 seconds
Therefore, the maximum height is at t = 5;
Substituting into equation 1 (the height function)
s = 160(5) - 16(5^2)
s = 800 - 400
s = 400 ft
The maximum height reached by the ball is 400 ft
Answer:
In the interaction between the bus and the bug, we can call the force "bus pushes bug" the action force. Then the force "bug pushes bus" is the reaction force. Since these forces are a Newton's Third Law action/reaction force pair, they are exactly the same size.
Explanation:
Newtons 3rd law
