Answer:
A
Explanation:
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
Answer:
Explanation:
This means that the ratio of the speed of the incident beam of light in a vacuum to the speed of light in the glass is 1.5
Answer:
The power dissipated in a resistor is 117.54 watts.
Explanation:
Given that,
Peak voltage of the Ac generator, V = 230 V
Frequency, f = 210 Hz
Resistance, R = 225 ohms
We need to find the power dissipated in a resistor. The power generated is given by :
So,
So, the power dissipated in a resistor is 117.54 watts. Hence, this is the required solution.
Answer:
15 m/s to the right
Explanation:
Let's say right is positive and left is negative.
Momentum is conserved:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(6.0 kg) (25.0 m/s) + (15 kg) (0 m/s) = (6.0 kg) (-12.5 m/s) + (15 kg) v₂
v₂ = 15 m/s
