Assuming this rate to be constant how many years will pass before the radius of the Moon's orbit increases by 3.6 x 10^6 m
Evgen [1.6K]

The number of years that will pass before the radius of the Moon's orbit increases by 3.6 x 10^6 m will be 90000000 years.

<h3>How to compute the value?</h3>

From the information given, the orbit of the moon is increasing in radius at approximately 4.0cm/yr.

Therefore, we will convey the centimeters to meter. This will be 4cm will be:

= 4/100 = 0.04m/yr.

Time = Distance / Speed

Time = 3.6 x 10^6/0.04

Time = 90000000 years.

Complete question:

Tidal friction is slowing the rotation of the Earth. As a result, the orbit of the moon is increasing in radius at approximately 4.0cm/y. Assuming this rate to be constant how many years will pass before the radius of the Moon's orbit increases by 3.6 x 10^6

You are using a constant force to speed up a toy car from an initial speed of 6.5 m/s
Pachacha [2.7K]

By the work-energy theorem, the total work done on the car is equal to the change in its kinetic energy:

<em>W</em> = ∆<em>K</em>

<em>W</em> = 1/2 (0.34 kg) (22.9 m/s)² - 1/2 (0.34 kg) (6.5 m/s)²

<em>W</em> ≈ 82 J

What are 3 types of cells that helper T cells produce upon being an alarmed of an antigen? Thanks for your help!! :)
Svetllana [295]
Whenever these are an alarming due to a foreign antigen, the Helper T cells, Memory T cells, and Cytotoxic T cells are being produced. Helper T cells to recognize the specific foreign antigen that is entering the body, Memory T cells to remember the specific foreign antigen that is attacking, and Cytotoxic T cells that are for the destruction of the foreign cells and produce cytokines to attract macrophages

What is a reasonable estimate of the average kinetic energy of an athlete during a 100 m race that takes 10s?
arlik [135]
The average weight of an athlete should be around 60kg so from the information that the athlete can run 100m in 10s, we can calculate that their average speed is 10m/s. Using the kinetic energy formula, Ek = 1/2mv^2 we can calculate the kinetic energy using 60kg as the mass.

(1/2)(60)(10^2) = Ek

Ek= 3000J
