Answer:
decreases, but frequency increases.
Explanation:
Wavelength and frequency are inversely proportional, meaning the higher the frequency, the shorter the wavelength, and the lower the frequency, the longer the wavelength.
Answer: Arrow B
Explanation:
Arrow B best best represents the path the ball follows after the string breaks.
This is because the described situation is related to <u>uniform circular motion</u>, in which the tangential velocity is the linear velocity vector that is <u>always tangent to the trajectory</u> and is the distance traveled by the ball in its circular motion in a period of time.
Hence, if this circular motion suddenly stops, the ball will fly in a direction that is tangent to that circle.
Answer:
No .
Explanation:
The vapor pressure of water at room temperature is .0313 atom or 3.13 kPa.
To make a liquid boil, its vapor pressure must be equal to pressure around it.
So pump must create pressure of 3.13 k Pa or less to make water attain its stage of boiling at room temperature. As the motor can not produce pressure lesser than 15 k Pa , pump will not be able to make water boil at room temperature.

Answer:
the change in energy of the block due to friction is
Explanation:
From the question we are told that
The frictional force is
The mass of the block is
The length of the ramp is
The height of the block is
The change in energy of the block due to friction is mathematically represented as
The negative sign is to show that the frictional force is acting against the direction of the block movement
Now substituting values
Answer:
Every object in space exerts a gravitational pull on every other
explanation : gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It can also cause life-destroying asteroids to crash into planets..
