Okay so i have a few questions:
1. an individual has a weight of 735 newton’s. what is the individual’s mass? show the appropriate equation and show your work
2. a temperature of a 50kg block increases by 15 degrees celsius when 337,500 j of thermal energy are added to the block. what is the specific heat of the object? show your work
(what is the block made of? ) (is this block a good material for insulators or conductors)
3. describe how the velocity and acceleration of a skydiver changes as she falls from the plane back to the ground.

1.

m = 74.9 kg

Explanation:

As we know that weight of the object is force due to gravity

Now we know that

2.

Explanation:

Heat added to the system is given as

so we will have

3.

Velocity will increase while acceleration will remain constant

Explanation:

When skydiver falls from rest then velocity will increase with time while the acceleration due to gravity will remains constant.

So here we can say that

while velocity will increase while it falls from certain height

this is a good question! i'll do some research and come back when i have the answer!

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
