296/km from city A, the vehicles will pass each other.
Answer:
My answer to the question is "250kg motorcycle moving at a speed of 45m/s.
<span>The force acting on the ball is the same than the ball acts on the floor at the moment of hitting but in the reverse direction. So the ball produces a force downwards and the floor makes the same force in value but upwards.
Then the value of the force that impulses the ball upward is: F = m * a
where F is force or impulse, m is mass of the ball and a is acceleration (9.8 m/s2)
F = 1.2 kg * 9.8 m/s2 = 11.76 kg*m/s2 = 11.76 Newtons (upwards)</span>
Answer:
Voltage of the secondary coil is 720 volts.
Explanation:
Number of turns in primary coil, N₁ = 60
Number of turns in secondary coil, N₂ = 360
Input rms voltage of primary coil, V₁ = 120 V
We have to find the output rms voltage of the secondary coil. The relationship between the number of coil and voltage is given by :


V₂ = output rms voltage of the secondary coil.
After solving above equation, we get :
V₂ = 720 V
Hence, the output rms voltage of the secondary coil is 720 volts.
