The Earth takes (365 and 1/4) days to orbit the sun. That's the length of our 'year'.
Since it's not really possible to make our calendar a quarter of a day longer every year, we make the calendar a <u><em>whole</em></u> day longer every 4 years.
So "Leap years" make up for the extra one-fourth day the Earth takes to orbit the sun.
The average speed is the distance per time ratio. velocity is the rate at which the position changes
You didn't give us anything other than the question. No options are provided so I cannot answer. Nobody can.
Answer:
w = 98.1[N]
Explanation:
The weight of a body independent of its speed or acceleration, will always be equal to the product of its mass by the acceleration of gravity.
In this case we have:
w = m * g
where:
m = mass = 10 [kg]
g = gravity = 9.81[m/s^2]
w = 10 * 9.81 = 98.1 [N]
