What happens in energy transformations with the total amount of energy?

Answers

Answer 1

Answer:

Answer:

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

Explanation:

cause it is energy

Light travels 300,000,000 m/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year. State this distance in centimeters.

Answers

   (3 x 10⁸ meter/sec) x (100 cm/meter) x (3.2 x 10⁷ sec/year)

   = (3 x 10⁸ x 100 x 3.2 x 10⁷) (meter-cm-sec) / (sec-meter-yr)

   = ( 9.6 x 10¹⁷    ) ( cm/yr )

In which direction should you look to see the setting moon.

Answers

Every sky object sets in the west.

It depends on the time of day. If it's just after moonrise, look in the east, low in the sky. Then near moonset, look in the west, also low in the sky.

Big Al stands on a skateboard at a rest and throws a 0.5-kilogram rock at a velocity of 10.0 m /sec. Big Al moves back at 0.05 m/sec. What is the combined mass of Big Al and the skateboard?

Answers

let
his and skateboard's combined mass is x
we know
F1=-F2
0.5kg*10m/s=-0.05m/s xkg
5=0.05x(minus cancel with the m/s as it represented the opposite direction of velocity and now there is no velocity in this equation.. so minus is avoidable. and the kgs cancel out)
x=10
so their combined mass is a 100 kg.. (I hope I didn't mess thing up for you)
