Can u show the problem ?
Acceleration= the rate and change of an object also cars go fast so I think it would be positive acceleration
Hope I helped
The answer will be pressure.
Pressure is force per unit area.
Answer:
I_2 = 0.146 A
Explanation:
The formula for current in an inductor is;
I_rms = V_rms/X_L
Where X_L is inductance wirh formula 2πfL
So, I_rms = V_rms/X_L
Applying this to the two generators, we have;
First generator;
I_1 = V_rms/(2π(f_1)L)
And I_2 = V_rms/(2π(f_2)L)
Thus, to find the current in the second generator, we divide eq 1 by eq 2;
So,
I_2/I_1 = [V_rms/(2π(f_2)L)]/[V_rms/(2π(f_1)L)]
Some values will cance out leaving us with;
I_2/I_1 = f_1/f_2
I_2 = I_1(f_1/f_2)
Plugging in the relevant values ;
I_2 = 0.56(1.2/4.6)
I_2 = 0.146 A
Formula: PE = mgh
m = 20 kg, g = 9.8 m/s^2 h= ?
1000 = 20 * 9.8 * h
1000 = 196h
h = 5.10204082
The height is around 5m
