Seismic wave is the answer
Answer:
Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x.
A should be the answer since it makes the water down there cold and the air also. (asked my grandma haha
The time it takes for the Moon to rotate once around its axis is equal to the time it takes for the Moon to orbit once around Earth
The drag force acting on the rocket is 80N.
<h3>Give an explanation of drag force?</h3>
The divergence in velocity between the fluid and the item, also known as drag, exerts a force on it. Between the liquid and the solid object, there should be motion. Drag is absent in the absence of motion.
The air molecules are more compressed (pushed together) on the surfaces that are facing the front while being more dispersed (spread out) on the surfaces facing the back. Turbulent flow, which occurs when air layers split from the surface and start to swirl, is what causes this.
The drag force acting on the rocket F = ma
Given,
m = 4kg, a = 20ftm/s²
Substituting m and a values in the above formula,
The drag force acting on the rocket F = 4×20
The drag force acting on the rocket F = 80N.
