Answer is (1) - less mass and greater penetrating power.
Alpha particle is a ₂⁴He nucleus while beta particles are electrons. Hence, the mass of alpha particle is greater than the mass of beta particle. But, the penetrating power is higher in beta particle than alpha particle. Alpha particles can be blocked by few papers but beta particles can go through those papers.

Explanation:
The main cause of the erosion that formed the Grand Canyon was water; most scientists agree that it formed when the Colorado River started carving through layers of volcanic rock and sediment between five million and six million years ago
Answer:
the coefficient of y is -7
A-Locations M and O are at the poles.
Explanation:
Locations M and O are located at the poles because they receive sunlight that is spread out over a large surface area. The poles receive sunlight at an angle to the surface and it causes the rays of the sun to spread out in all direction.
- At the equator, sunlight impinges directly on the surface and the solar radiation here is very much.
- It is important to know that the sun is overhead directly at the equator.
- The earth is tilted at an angle to sun and therefore, areas around the polar region will receive sunlight that is spread out in different directions over a large area.
- Away from the pole, the equator is directly facing the sun and it receives direct sunlight.
