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

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
