N a physics lab experiment, a student sets up an inclined ramp on a table with two photogates 20 cm apart. A ball rolls down the ramp and the photogates read that it takes 0.25s for the ball to pass through photogates. If the end of the table is 87 cm above the floor, What is the ball’s horizontal velocity?
Where could a coin be placed so that the ball directly strikes the coin on impact with the ground?

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

wavelength divides in half and speed stays the same.

i believe the answer is a hope it and is correct

well clustered together.
