Answer:

Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. ... In June, when the Northern Hemisphere is tilted toward the sun, the sun's rays hit it for a greater part of the day than in winter.

Answer:

It is because the earth's spin axis is tilted with respect to its orbital plane

Explanation:

This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. I hope it helps you

What conclusions can be drawn about the decrease in the number of grass blades in both the experimental and control groups?
emmainna [20.7K]

The control group is the group that does not receive the experimental treatment. Experimenters use the control group to compare it to the experimental group in order to determine if the treatment had an effect. So, if there is the same result in both groups (decrease in the grass blades) it means that the given treatment had no effect on the experimental group and that the decrease is due to some other conditions.

4) If an object of 40 kg is moving east at 20 m/s and collides with a 20 kg object moving along the same vector at 10 m/s, what
Anuta_ua [19.1K]

Answer:

The smaller object will move at 30 m/s

Explanation:

From the principle of conservation of linear momentum,

Momentum of objects before collision = momentum of objects after collision.

m_{1}v_{1} + m_{2}v_{2}=m_{1}v_{3}+m_{2}v_{4}

where m_{1}, m_{2} , v_{1}and v_{2} are the masses  and velocities of the objects 1 and 2 respectively before collision.

40\times 20 + 20\times 10 = 40\times 10 + 20\times v_{4}

1000= 400 + 20v_{4}

v_{4}=30m/s

Hence, the object will move at 30 m/s
