FASTA ball has 116.62 J of gravitational potential energy at a height of 85 m. What is the mass of the ball?

a.0.14 kg
b.0.37 kg
c.11.9 kg
d.21.82 kg

Answers

Answer 1
Answer:

Answer:

a)0,14 kg

Explanation:

Formula to calculate the gravitational potential energy:

U=  m *g*h  : equation (1)

U: It's gravitational potential energy in Joules (J)

m: body mass in kilograms (kg)

g= the acceleration of gravity (m/s^(2))

h= the body heigt measured from the floor (m)

Known information:

U= 116.62 J

g = 9.8 m/s^(2)

h =85m

mass calculation:

We replace the known information in equation 1 :

116.62 = m*9.8*85

m =116.62/(9.8*85)

m= 0,14 kg

The mass of the ball is 0,14 kg  

Answer 2
Answer: The answer is a. 0.14 kg

PE = mgh
116.62 = m•(9.8)•(85)
m = 116.62/(9.8•85)
= 0.14 kg

The driver of a 1500 kg car, travelling on a highway, hits the brakes. A force of 12000 N stops the car in a distance of 64 m. how fast was the car going when the driver hit the brakes?

Answers

Answer:

v = 32 m/s

Explanation:

As per work energy theorem we know that work done by all the forces must be equal to change in kinetic energy of the car

So here when brakes are applied then work is done by the brakes which is equal to change in kinetic energy of the car

so we know that work done by the brakes is given as

W = -12000 * 64

W = -768000 J

now we will have

W = 0 - (1)/(2)mv^2

-768000 = - (1)/(2)(1500) v^2

v = 32 m/s

Which alternative energy source would be expected to be the least dependent upon the weather?a. wind power
b. solar power
c. geothermal power
d. none of the above

Answers

Answer;

C. geothermal power

Explanation;

Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content. It depends the least on weather.

Geothermal energy is the heat from the Earth. 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.

Of the three sources listed, geothermal energy
is the least dependent on the weather.
(Once it's installed and running, that is.)

The principal limitation of wind power is unpredictability. Please select the best answer from the choices provideda. True
b. False

Answers

The correct answer is A: True. Although the ability to forecast weather has increased over the years, the ability to predict when and how much wind will occur at any given time and place is difficult. Weather conditions are subject to constant change and while some areas are known to have more wind than others, there is no guarantee about how much wind there will be as weather patterns vary in consistency.

Photosphere, convective zone, radiative zone
Convective zone, chromosphere, corona
Radiative zone, corona, convective zone

Answers

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers. Option A is correct.

What are the layer of sun?

Corona, photosphere, chromosphere are the layers of the sun in the correct order from innermost to outermost.

The distance is measured from the sun's core for the inner layers and from the sun's surface for the outer layers. The Core and Convection Zone, are the inner layers.

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers.

Hence, option A is correct.

What is geothermal power

Look at the parts of the word ... you've seen them both before:

"Geo ..." . . . has something to do with the Earth.

"... thermal" . . . has something to do with heat.

"Geothermal" . . . "Earth heat".

You know that the Earth's core is liquid metals, at high temperature.
You may also know that when people go down into a deep mine, it's
always warm down there.

Some of the heat from the Earth's core soaks up through the Earth,
and there's actually a lot of it available without going too deep below
the surface.

You may have read about "hot springs" ... pools of water that are always
hot, because they extend down deep and get heated by the Earth's heat. 
And you may have seen pictures or videos of "geysers" ... deep holes in
rock where there's water down at the bottom, which gets heated by the
Earth's heat, and when it gets to boiling temperature, this stream of hot
water and steam comes shooting up out of the hole.  There are a lot of
those geysers in Yellowstone National Park in Wyoming.

Well, if there's enough of this hot water close enough to the surface,
then you can actually install pipes to bring it up to the surface, use the
hot water to heat houses and buildings, and even use the steam to spin
turbines and generate electric power !  Then you're using "Geothermal"
energy . . . "Earth heat".

If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same. Please select the best answer from the choices provided T F

Answers

Answer: The correct answer is True.

Explanation:

Average kinetic energy of the particles is defined as the average of the kinetic energies of the particles present in a medium. It is the measure of temperature of the medium.

Mathematically,

K=(3)/(2)(RT)/(N_A)

where,

K = kinetic energy

T = Temperature

\text{Kinetic energy}\propto \text{Temperature}

As, kinetic energy of the particles is directly proportional to the temperature. Increase in temperature will result in the increase in the kinetic energy and vice-versa.

We are given, that the temperature of the two glasses are same, so the average kinetic energy of the particles will also remain same.

Hence, the correct answer is True.

The statement ‘If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same’ is true. This is because temperature is directly proportional with the kinetic energy of the molecules. If there is no change in temperature, there would not be kinetic movement of the molecules.
