Explanation:
Given
Range of ball =7.88 m
Initial speed=13.1 m/s
and we know
Range of Projectile is
(b)other angle would be complementary of 
Answer:
0.0025 sec
Explanation:
Period = 1 / frequency = 1/400 = 0.0025 sec
1.) core- the central region where nuclear reactions consume hydrogen to form helium
2.) radiative zone- the section of solar interior between the innermost core and the outer convective zone.
3.) convection zone- where light (photons) is created.
4.) photosphere- the visible surface of the sun that we are most familiar with
5.) chromosphere- second most outer layer of the sun. due to low density it is relatively transparent and only apparent during eclipses.
6.) corona- an aura of plasma that surrounds the sun and other stars but is usually hidden by the bright light of the sun’s surface.
The acceleration goes up.
