Question # 40

Physics
1 answer:
jenyasd209 [6]3 years ago
7 0

Answer:

Potential Energy = x = m g h

Kinetic energy = 1/2 m v^2

Assuming the mass fall from rest

1/2 m v^2 = m g h

v^2 = 2 g h

So the speed attained is independent of the mass

Also, x / v   does not have the units of mass

So the solution is none of the above.

How will a current change if the voltage in a circuit is held constant while the resistance doubles? 1. it's impossible to predi
laila [671]
According to Ohm's Law: 

I =  \frac{V}{R}

Where: V = Voltage
            I = Current
            R = Resistance

As you can see here, you can say that Current is directly proportional to Voltage and indirectly proportional to Resistance. This means that as the voltage increases, current increases and as the resistance increases, current decreases. 

So in your scenario, if the voltage remains the same, but the resistance is doubled, that means that the current will be halved. So the answer to your question is 2. the current will drop to half of its original value.

A 1569 kg car moves with a velocity of 15 m/s. What is its kinetic energy? Joules
Crank
Kinetic energy = 1/2 * mass * velocity^2

In this case,
KE = 1/2 * 1569 kg * (15 (m/s))^2 = 176,5 kN
