Answer:.
Coriolis effect and Temperature differences between the equator and the polar areas.
Explanation:
Global winds are created by both the spin of the Earth (Coriolis effect) and the differences in temperature between the equator and the polar areas. These winds are often grouped together as trade winds, easterlies, and westerlies.
Look at the rock sitting on the hill in the picture above. Gravity should make the rock slide down the hill. What force is acting to balance gravity,keeping the rock in place? - D. friction
Centripetal force and momentum have to do with movement. Gravity cannot balance gravity.
The purpose of an air filter is to purify the air around you removing particles such as dust from the air.
Answer:
(b) Water
Explanation:
The density of the liquid is found by dividing its mass by its volume.
__
<h3>mass</h3>
The mass of the liquid is the difference in mass between the full and empty graduated cylinder:
liquid mass = (145 g) -(45 g) = 100 g
<h3>volume</h3>
The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.
<h3>density</h3>
The ratio of mass to volume is the liquid's density:
ρ = (100 g)/(100 mL) = 1 g/mL
This density identifies the most likely liquid as water.
