Question

**Question 1-** A man has a mass of 65 kg on the
Earth's surface. How far above the surface of the Earth would he
have to go to "lose" 11 %of his body weight?

**Question 2-** A 195 kg object is taken to a
height of 390 kmabove the Earth's surface. What is the object's
mass at this height? and What is the object's weight at this
height?

Answer #1

EDIT:

(2)

A 100 kg object is taken to a height of 370 km above the Earth's
surface.
A)What is the object's weight at this height?

2. A 65 kg man is standing at the Earth's surface.
(a) What is the approximate magnitude of the gravitational force on
the man by the Earth. Give your answer in newtons. Get the mass and
radius of the Earth from the inside back cover of your text.
Remember, enter only the number; don't try to enter the
units.
N
(b) What is the approximate magnitude of the force of gravitation
on the same man by the Sun. You may...

Compare the weight of a 5.40-kg object on Earth's surface to the
gravitational force between a 5.40-kg object that is one Earth
radius from another object of mass equal to 5.98 ×× 1024
kg. Use Newton's universal law of gravitation for the second part
of the question.
2)
Determine the gravitational force an Earth radius away.
(Express your answer to three significant figures.)

A 345 kg satellite is orbiting on a circular orbit 8955 km above
the Earth's surface. What is the gravitational acceleration at the
location of the satellite? (The mass of the Earth is
5.97×1024 kg, and the radius of the Earth is 6370
km.)?

A satellite is orbiting Earth 1,790 m above Earth's surface.
Earth has a mass of 5.97×1024 kg and a radius of
6371×103 m. What is the satellite's speed? Answer in SI
units, rounded to the nearest whole number.
Thank youuuu

A 1.88 -m ( 6 ft 2 in. ) man has a mass of 99 kg, a body surface
area of 2.2 m 2 , and a skin temperature of 35.3 ∘ C. Normally, 80
% of the food calories he consumes go to heat; the rest goes to
mechanical energy. His emissivity e is 1 because his body radiates
almost entirely nonvisible infrared energy, which is not affected
by skin pigment. (Careful! His body at 35.3 ∘ C radiates...

A man of mass m=74.0 kg is holding his breath and floating, at
rest, on the surface of a lake. While holding his breath, his
density is p=994.0 kg.m^3. He exhales, which increases his density
to 1030.0 kg/m^3 and so he begins to sink. The density of water is
1000.0 kg/m^3.
a) when the man is floating at the surface of lake, what percent
of his body's volume is above water?
b) once the man exhales, what is the buoyancy...

A person of mass 75 kg is standing on the surface of the
Earth.
a. Calculate the total energy of this individual, assuming they
are at rest relative to the surface. (Hint: Use the expression for
gravitational potential energy (*NOT Ug=mgh*)). Although
the person is standing at rest relative to the surface of the
Earth, they are rotating along with the Earth and thus store some
kinetic energy.) Ignore the rotation of the Earth about the Sun,
the motion of...

A satelite in a circular orbit has an orbital period of 189
minutes . On Earth the satelite weighs 980 N. The earth's mass is
5.97 × 1024 kg, its equatorial radius is 6.3 × 106 m, and G = 6.67
× 10−11 N • m2/kg2.
How far is the satellite above the earths surface?
How far is it from the earths surface?
If the weight of the satelite on Earth were 8820 N instead of
the 980 N given...

A satellite (mass 2400 kg) is orbiting the Earth, with a speed
of 7500 m/s. What is the height of this satellite above the Earth's
surface?
Note: you may find the following information useful. The
universal gravitational constant is 6.67x10-11
Nm2/kg2 ; the mass of the Earth is 6.0 x
1024 kg; the radius of the Earth is 6.4 x 103
km.
can you please show work if you can? I APPRECIATE YOU!!!
