Answer:

The sun is father away during the winter.

Explanation:

In the northern hemisphere, during the winter it is summer in the southern hemisphere. The sun is farther away for us so the days get shorter in the winter since the sun inches away faster.

Answer:

Tilt of the Earth

Explanation:

The Earth's rotational axis is titled at an angle 23.4°. When then northern hemisphere is pointed towards the Sun it is summer in the northern hemisphere and winter in the southern hemisphere.

In the northern hemisphere a day would be longer and gets more sunlight than the southern hemisphere.

The same happens when it is summer in the southern hemisphere.

a baseball is thrown vertically upwards and returns to the thrower three seconds later find speed at which the ball us thrown

rodikova [14]

Answer:

14.7 m/s

Explanation:

Since the motion of the ball is a uniformly accelerated motion, we can find the initial speed by using the following suvat equation:

$s=ut+\frac{1}{2}at^2$

where

s is the vertical displacement

u is the initial velocity

t is the time

a is the acceleration

In this problem, we have:

s = 0 (because at the end of the motion, the ball returns to its original position)

u = ?

$a=g=-9.8 m/s^2$ is the acceleration of gravity (negative because it is downward)

$t = 3 s$ is the total time of flight

Solving for u, we find the initial velocity of the ball:

$0=ut+\frac{1}{2}at^2\\u=-\frac{1}{2}at=-\frac{1}{2}(-9.8)(3)=14.7 m/s$

Why does a rolling sphere slows down?

VLD [36.1K]

The sphere slow down due to friction force between the surface of the sphere and the surface on that the sphere is rolling . The friction force acting against the motion of the sphere. Thats why it is slowed down. In fact not only a sphere, anything can not slow down untill a force act against it's motion.
