The type of metal of the wire
The distance from the wire
The amount of the current
Answer:
24 m/s
Explanation:
Given that,
A typical road bike wheel has a diameter of 70 cm including the tire.
Speed of the cyclist = 12 m/s
We need to find the speed at the top of the tire moving. The velocity of the topmost point is twice that of the velocity of the object.
v = 2 × 12
= 24 m/s
Hence, the required velocity is 24 m/s.
The momentum p of a moving particle is the product between its mass, m, and tis velocity, v:
In our problem, we know
and
, and using the relationship mentioned above, we can find the mass m of the particle:
The answer is D “the lake contains more mass and more heat than the cup of water”
