"D. Magnetic and electrical forces are similar because they are both related to the interactions between charged particles" best describes how the forces relate.
==> Object A travels for 60 seconds before Object B starts out.
==> Object A moves at 2 m/s.
==> So Object A has a lead of 120 m when Object B starts out.
==> Object B moves at 3 m/s . . . 1 m/s faster than Object A.
==> So Object B catches up on Object A by 1 m every second.
==> Object B closes up Object A's lead of 120 m in <em>120 seconds</em>.
The potential energy is directly proportional to the height.
If you double the height you double the potential energy.
Answer:
A = 26.875 rad/s²
Explanation:
<u>Given the following data;</u>
Initial angular speed, Uw = 150 rads/s.
Final angular speed, Vw = 580 rads/s.
Time = 16 seconds.
To calculate the angular acceleration;
From kinematics equation;
At = Vw - Uw
Where;
- A is the angular acceleration.
- t is the time
- Vw is the final angular speed.
- Uw is the initial angular speed.
Substituting into the formula, we have;
A*16 = 580 - 150
16A = 430
A = 430/16
<em>A = 26.875 rad/s²</em>
Answer:
0.01663 Nm
Explanation:
N = 1000, r = 12 cm = 0.12 m, i = 15 A, B = 5.8 x 10^-5 T, θ = 25
Torque = N i A B Sinθ
Torque = 1000 x 15 x 3.14 x 0.12 x 0.12 x 5.8 x 10^-5 x Sin 25
Torque = 0.01663 Nm
