What has to happen for a feather and a ball to fall at the same rate?

Answers

Answer 1

Answer: Because the force of gravity is different for both of these objects, they will not fall at the same rate. To make both of these fall at the same rate, we need both to have the same mass so that the gravitational pull is equivalent also.

Answer 2

Answer: They will NOT fall at the same late.
A ball will fall much faster than a feather. A feather tends to float down, much as a ball, it immediately drops.

Bone-strengthening physical activity done _____ increases bone-mineral content and bone density in youth.

Answers

Hi!

The answer would be three days a week

Explanation

Bone-strengthening activity is key to ensuring that bones remain healthy to maintain an individual's lifestyle. The physical activity to strengthen bone may be brisk walking, exercises that include weights, or gymnastics to lift a few. The purpose of these activities are to observed to contribute to an increase in the bone mineral density of adolescents and children. Several studies have established that about 150 minutes a week for adults, or 3 days a week (60 minutes a day) for the youth should be devoted to bone strengthening physical activity to ensure good health of the body.

Hope this helps!

Answer:

three or more days a week

Explanation:

While watching a recent science fiction movie, one Klingon spaceship blows up a Droid spaceship with a laser gun. The Klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. Scientifically, this scene is inaccurate because A)
light can not reflect off objects in the vacuum of space.

B)
they would not be able to see anything outside the window.

C)
lasers can not be transmitted through the vacuum of space.

D)
the sound of the explosion would not be transmitted back to their ship.

Answers

Answer:

D) the sound of the explosion would not be transmitted back to their ship.

Explanation:

Sound is a mechanical wave. A mechanical wave requires a medium to travel and transfer energy. It travels be compression and rarefaction of the medium. Since in space it is vacuum, the sound energy by the explosion of the spaceship would not be able to travel through the space, the Klingon crew are not required to cover their ears to muffle the noise. This scene would be inaccurate scientifically.

How does lightning occur?

Answers

I've learned that lighting occurs when clouds in the sky bump into each other. The harder the clouds bump into each other, the louder and bigger the lighting gets :D

The positive and negative electrons split in the cloud

Positive going to the bottom of the cloud and negative to the top.

Since you are made of negative electrons, you attract the positive electrons to you causing you to get struck by lightning.

The ground has negative electrons too!

This will shock the ground and end up shocking you as well, since the ground and you are connected.

Lightning and thunder are connected! They do happen at the same time. The reason why the thunder travels later than the lightning is because you are away from the lightning and the sound waves are just getting near you

B.) How are thunderstorms dangerous?

Thunderstorms are dangerous because they give off positive energy. If you are standing outside while a thunderstorm is in session, you could get shocked since you are made of negative energy and attract positive energy.

If your hair is sticking straight up, you are about to be struck by lightning. Crouch down and cover your head next to your ears and prepare for impact.

You might ask, "Why can't I just run from the lightning?" That is true, but since you aren't faster than light itself, you will still wind up caught in the storm.

Avoid this by staying inside.

Hope this helps <3
