An oscillator makes four vibrations in one second. What is its period and frequency?

Answers

Answer 1
Answer: Frequency = no. of oscillations/ time

= 4 / 1
= 4Hz

Time period = 1/ frequency

= 1/ 4

= 0.25 seconds.

Answer: a

Explanation: Hope it helps

Answer:

A

Explanation:

I think its a because A would be heavier making it go down faster than B. its like when you drop a father compared to a ball, the feather is lighter so it will go down slower than the ball because it has more mass

Why do the kites and eagles fly without flapping their wings?

Answers

Answer:

because they both have large area to capture air

Answer:

Because they have a large surface area to capture moving air when going at a certain speed.

Explanation:

When your trying to fly a kite and the wind isn't that much, you have to run so that the kite can come in contact with the fast moving air which pushes the kite to go up. Just like a eagle because when a eagle is trying to fly, it has to first flap its wings to push air downwards so that it can create lift and at a certain altitude, the eagle doesn't have to flap it's wings though it tilts its body downwards a little so that gravity can do the work, so the eagle is basically gliding downward.

A person walks out of a store with a pillow at the top of an overflowing shopping cart. While walking to the car, the cart's wheel hits a large rock, causing the cart to suddenly stop. Which of the following is likely to happen as a result of Newton's first law of motion?

Answers

The pillow will continue to go forward as Newton's first law states that an object will continue in it's path unless another force acts upon it
