Energy is the capacity of doing work
<u>Answer:</u>
total mass = 410 g
<u>Explanation:</u>
density = 1.8 g/cm³
volume = 200 cm³
density = mass / volume
mass (of liquid) = density x volume
= 1.8 x 200
= 360 g
total mass (beaker + liquid) = 50 + 360 = 410 g [Ans]
Hope this helps!
Because we can reproduce with just one and if more eggs were released, the female reproductive life (which is 40 years) would be shorter and so there would be less time for every female human to reproduce since the amount of eggs is limited. (Also fraternal twins come from 2 eggs released at the same time)
They are poor conductors because they keep the heat trapped in one spot, while other materials like metal let the heat go through itself.
Answer:
2.83 x 10^4m/s
Explanation:
First, let us calculate the time taken by the object to hit the surface of the earth.
H = 4.1 x 10^7m
g = 9.8m/s2
t = √(2H/g)
t = √((2x 4.1 x 10^7) /9.8)
t = 2892.64secs
Now, we can find the velocity with which the object strikes the earth as follows:
V = gt
V = 9.8 x 2892.64
V = 2.83 x 10^4m/s
