Answer:
1788.402 MJ
Explanation:
Work done = Force (N) x distance (m)
First we have to convert distance into metres:
173.8 x 1000 = 173,800 m
Then plug these values into the equation above:
173,800 x 10290 = 1788402000 J
The reason it's Joules (the unit for energy) is because work done = energy transferred
Now we have to convert Joules into Mega Joules:
1 J = 1/1000000 MJ
1788402000 J = 1788402000/ 1000000 = 1788.402 MJ

Rose and Joel's children recently moved out to live independently. The couple has been missing their kids and is experiencing the empty-nest syndrome. Which TWO strategies will help them deal with their loneliness? -pursuing a hobby -joining an activity club with like-minded people -calling their children regularly -visiting their children frequently -convincing their children to move in back home with them
Answer:
Joining a club and getting a hobby
Explanation:
Join a club if you want to meet people, and when they choose a hobby it should be more than just gardening, because gardening sucks in the long term and it doesn't fill that gap. I know because my grandma did it and she is still sad.
1. If you add air to a flat tire through a single small entry hole, why does the air spread out to fill the tire?
Answer:
The tire fills up just like anything else that holds air when u pump a ball or tire up it fills all the way up cause it is a small confined space and after filling it with air the atoms of the air fill the tire up

PLZZZZZZZZZ HELPPPPP. BRAINLEST GIVEN What is a force of attraction between an object and the earth due to gravity?
Answer:
acceleration due to gravity: -9.8 m/s^2
Fg=mass of object*(-9.8)
Explanation:
This is a pretty vague question, but I'll answer as best I can.
All matter has gravity. YOU have gravity, although your gravitational pull is small. So, the force of attraction between the Earth and an object on Earth is modeled as
Force of gravity=(Gravitational constant*mass of object 1*mass of object 2)/distance between objects squared
Note that distance between an object on Earth and Earth is the radius of Earth (distance to Earth's core/center of mass)

in hydraulic pressure the area of the larger piston is half of the smaller piston.if the force of 4000N is applied on the smaller piston.what is the distance covered by the train ?
Answer:
The distance moved by the train is half the distance moved by the force
Explanation:
Given that the force applied to the smaller piston, F₂ = 4,000 N
The pressure in the area of the larger piston, A₁ = 2 × The pressure in the smaller piston, A₂
∴ A₁ = 2 × A₂
We have;
[tex]\dfrac{A_1}{A_2} = \dfrac{2\cdot A_2 }{A_2} =2 = \dfrac{F_1}{F_2}[/tex]
F₁ = 2·F₂ = 2 × 4,000 N = 8,000 N
F₁·d₁ = F₂·d₂
∴ 8,000 N ×d₁ = 4,000 N × d₂
d₁ = 1/2·d₂
∴ The distance moved by the train is half the distance moved by the force

Which graph best represents the relationship between KE and speed?
A graph with vertical axis K E and horizontal axis Speed with a straight line sloping sharply upward.
A graph with vertical axis K E and horizontal axis Speed with a concave line sloping sharply upward.
A graph with vertical axis K E and horizontal axis Speed with a straight line sloping sharply downward.
A graph with vertical axis K E and horizontal axis Speed with a curved line going first upward and then downward.
A graph with vertical axis K E and horizontal axis Speed with a straight line sloping sharply upward.
Relationship between kinetic energy and speedThe kinetic energy of an object is directly proportional to the square of its speed which means that if kinetic energy of an object increases the speed of that object is also increases and vice versa so we can conclude that graph with vertical axis K E and horizontal axis Speed with a straight line sloping sharply upward is the right answer.

If a motor is rated at 5.6KW, work done in 20minutes is equal to:
Answer:
given Power= 5.6×1000=5600watt
t=20min=20×60=1200sec. work done=?
P=w/t
w=pt=5600×1200=672×10^4Joule
The amount of work done by the motor is equal to 6.72 Megajoules.
Given the following data:
Time = 20 minutesPower = 5.6 Kilowatt = 5600 Watts.Conversion:
1 minute = 60 seconds20 minutes = [tex]20 \times 60 = 1200[/tex] seconds.To determine the amount of work done by the motor:
Mathematically, the work done by an object with respect to power and time is given by the formula:
[tex]Work\;done = power \times time[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 5600 \times 1200[/tex]
Work done = 6,720,000 Joules

The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of the tube is 0.015m) find the velocity of the sound produced by the tuning fork.
Answer:
The velocity of the tuning fork sound is 317.4648 m/s
Explanation:
The given parameters are;
The frequency of the fork, f = 426.7 Hz
The length of the closed air column, L = 0.186 m
The diameter of the tube, d = 0.15 m
At the fundamental frequency in a closed tube, we have;
λ = 4·L
Where;
λ = The wavelength of the wave
L = The length of the tube
From the equation for the velocity of a wave, we have;
v = f·λ
Where;
v = The velocity of the (sound) wave
f = The frequency of the wave = 426.7 Hz
λ = 4·L = 4 × 0.186 m = 0.744 m
∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s
Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s

Explanation:
Well i took the quiz and made a %100 meaning i am correct.
The laterite soil is found in warm, humid climates
What are Laterite soil?A variety of rocks weathered under highly oxidising and leaching circumstances to form laterite soil, which is present in the soil layer and is rich in iron oxide.
Given data ,
Let the soil be represented as A
Now , the soil is found in warm, humid climates
The laterite soil is is rich in iron and aluminium, are assumed to have developed in hot, humid tropical climes. Because to the substantial concentration of iron oxide, nearly all laterites have a rusty-red colour.
They develop as a result of prolonged, intensive erosion of the underlying rock material, which most frequently takes place during periods of high temperatures and heavy precipitation that alternate with periods of dry weather.

question:
If all matter has a gravitational force, why don’t two tennis balls on the ground move towards each other on their own?
A. The force of gravity from the tennis balls is too small.
B.The tennis balls are outside of each other’s gravity field.
C.The tennis balls are too small to produce any gravity.
D.There is too much friction between the balls and the ground
(the picture is just of the question)
Answer:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Explanation:
I could be wrong but I would say B :)
Have a good day!
answer:
i believe the answer is d
explanation:
here's why;
c. is incorrect because everything has a gravitational force.
a. is also incorrect because gravity is what holds the tennis ball down and keeps it on the ground.
i don't really know how to explain why b. is wrong, but d. is the correct answer because the force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.
good luck :)

If two monochromatic light waves undergo destructive interference, the amplitude of the resultant wave is
Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
Answer:
No, the resulting wave in the diagram does not demonstrate destructive interference. The resulting wave in the diagram shows a bigger wave than Wave 1 or Wave 2. If it demonstrated destructive interference, it would be a smaller wave or a horizontal line. With destructive interference, waves break down to form a smaller wave, or cancel each other out, resulting in no wave formation.
