A ball is dropped from the top of a tall building. As the ball falls, the upward force of air rsistance becomes equal to the downward pull of gravity. When these two forces become equal in magnitude the ball will: a) flatten due to the forces b) fall at a constant speed c) continue to speed up d) slow to a stop

Answers

Answer 1
Answer: fall at a constant speed

Answer 2
Answer:

Final answer:

When the force of air resistance equals the downward force of gravity, the net force on a falling object becomes zero, meaning it will fall at a constant speed.

Explanation:

The subject of this question is Physics, specifically focusing on the aspects of forces, gravity, and air resistance involved when an object is in free fall. When the magnitude of the upward air resistance equals the downward pull of gravity, the net force on the ball becomes zero. According to Newton's second law of motion, when the net force on an object is zero, its acceleration is also zero, meaning it will not speed up or slow down. In this case, the ball will fall at a constant speed. Therefore, the correct answer is b) fall at a constant speed.

Which movement causes day and night on Earth?rotation of Earth
revolution of Earth around the Sun
Earth’s elliptical orbit in space
moon’s orbit around Earth

Answers

The movement causes day and night on Earth is the rotation of Earth.

What is rotation?

The rotation is the spinning around of an object about its own axis passing through the center.

When the Earth rotates about its own axis, the rotation completes in 24 hours. This causes the day to night and night to day. When the part of Earth is in front of Sun, there is day. But, when the same part of Earth goes away from the Sun, the sunset occurs and then eventually night occurs.

Thus, the movement causes day and night on Earth is the rotation of Earth.

The movement that causes day and night on Earth is the rotation of the earth on its axis, which is in option a as the earth rotates from west to east, completing one full rotation in approximately 24 hours.

As the Earth rotates, the side facing the sun experiences daylight, while the opposite side facing away from the sun experiences nighttime. This rotation creates the cycle of day and night that we observe on Earth. The other movements mentioned, such as the revolution of Earth around the Sun, Earth's elliptical orbit in space, and the moon's orbit around Earth, are not directly responsible for causing day and night.

Why don't the present shapes of the continents fit perfectly into the supercontinent?

Answers

The reason why the shapes of the continents as of today do not perfectly fi into to super continent because long time ago the super continent was scattered into pieces. And as times go by, those smaller parts of super continents undergo soil erosion caused by the water and other way that causes their original shapes change.  
Thus, if we are going to judge now if those smaller part of super continent, they’re no longer gonna fit perfectly because through time their original form changed
