Answer:
Protons have a positive charge
neutrons have a neutral charge
Electrons have a negative charge
Explanation:
Protons and electrons balance each other out.
Answer:
f = 10 Hz
Explanation:
We need to find the frequency of a wave if 10 waves go past in 1 second. Total number of waves per unit time is called frequency. So,
So, the frequency of a wave is 10 Hz.
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
Answer:
I think the correct answer is B.
Answer:
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth
