The characteristics of the shadow allow to find the result for the change of the sun's rays are:

  • As the person advances from the equator to the poles the rays are less perpendicular, which is reflected in a longer shadow.

The shade is a space where the sun's rays do not reach.

When the person is at the equator, his shadow is very small, indicating that the rays are falling vertically.

As the person increases his latitude, a shadow begins to appear every larger shade, due to two processes:

  • The earth is spherical, therefore there is an angle between the normal to the earth's surface and the sun's ray , which is why there is a region where the sun does not reach.
  • The Earth has an inclination with respect to the sun and this inclination changes in the course of the year.

When the person is just over the north pole, the shadow should be infinite, which indicates that the person is parallel to the sun's rays. In reality, due to the inclination of the earth, the shadow is very long, but finite.

In conclusion using the characteristics of the shadow we can find the result for the change of the sun's rays are:

  • As the person advances the sun's rays are less perpendicular, which is reflected in a longer shadow.

A ball, with a mass of 5.9kg, is thrown directly upwards. It reaches a maximum height of 10m from the point at which it was rele
katrin2010 [14]

Answer:

14 m/s

Explanation:

We can solve the problem by using the law of conservation of energy.

At the beginning, when the ball is thrown from the ground, it has only kinetic energy, which is given by

K=\frac{1}{2}mv^2

where m = 5.9 kg is the mass of the ball and v is its initial speed.

As the ball goes up, its speed decreases, so its kinetic energy decreases and converts into gravitational potential energy. When the ball reaches its maximum height, the speed has become zero, and all the kinetic energy has been converted into gravitational potential energy, given by:

U=mgh

where g = 9.8 m/s^2 is the gravitational acceleration and h = 10 m is the maximum height reached by the ball.

Since we can ignore air resistance, energy must be conserved, so the initial kinetic energy must be equal to the final potential energy of the ball, so we can write:

K=U\\\frac{1}{2}mv^2=mgh

And we can solve the equation to find v, the initial speed of the ball:

v=\sqrt{2gh}=\sqrt{2(9.8 m/s^2)(10 m)}=14 m/s

The atmosphere protects us from _____ and _____.
sveticcg [70]

Answer: B. meteorites, UV rays

The earth's atmosphere plays an important role in shielding the space rocks and meteorites enters inside the earth due to collision with the celestial body. Due to high heat and pressure in the mesospheric layer of the atmosphere these meteorites burned up before reaching the biosphere or hydrosphere system of the earth. The UV rays are protected from entering into the earth atmosphere by the ozone layer present in the stratosphere of the atmosphere. Both meteorites and UV rays can negatively effect the human population. Therefore, the atmosphere is an agent which provides protection against them.

Formulating a Hypothesis: Part I Since the investigative question has two variables, you need to focus on each one separately. T
Taya2010 [7]

Explanation:

The kinetic energy is said to be possessed due to the motion of the object. An object at rest will have zero kinetic energy and if it is in motion it will have some kinetic energy. The mathematical expression for kinetic energy is given by :

E=\dfrac{1}{2}\times m\times v^2...........(1)

Where

m is the mass of the object

v is the velocity of object

It is clear form expression (1) that the kinetic energy of the object is directly proportional to the mass and velocity of an object.

So, the hypothesis for the mass and kinetic energy can be written as " when the mass of the object increases, its kinetic energy also increases because there exists a direct relationship between the mass and the kinetic energy of the object".
