It will take the ball 4 seconds to reach the ground because (120/2= 60/2=0= 2+2=4)
Answer:
Option B) It decreases as someone moves away from earth's surface.
Explanation:
The atmospheric pressure at the surface of the earth is at maximum, it is seen that as we move away from the surface of the earth the pressure decreases. As on the top of mountains the atmospheric pressure is found to be low as compared to the surface of the earth.
It is assumed that the atmospheric pressure is caused due to hydrostatic measurements where the changes caused by weight of air are measured.
Also, it is observed that when there is an elevation, the atmospheric pressure decreases.
Answer: 0.125
Explanation:
Given that the
Object height U = 24.8 cm
Image height V = 3.09 cm
Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.
M = V/U
Substitute V and U into the formula above.
M = 3.09/24.8
M = 0.125
Magnification is therefore equal to 0.125 approximately
By remilitarizing Germany, Hitler violated the treaty of Versailles. So the correct answer is D.
The treaty of Versailles was signed after the end of the first World war and among its main points was that Germany would not remilitarize again. This is what Hitler did and violated the point.
