How is the 3rd law different from the 1st and 2nd laws?
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Explanation:
A force of 600N is used to slide a sled across a floor 20 meters . The rope pulling the sled is held at 35 * . How much work does the force do?
Answer:
9830 J
Explanation:
(Just a tip, you should use the degree symbol ° instead of *)
That being said we know W = F*d*cos(θ). In this case θ = 35°.
W = F*d*cos(θ) = 600*20*cos(35)
= 12000*cos(35)
= 9829.925 Joules
Solution: Work ≈ 9830 J
What is the difference between epicenter and focus?
Answer:
The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus.
Explanation:
What is the acceleration of a 7 kg mass if the force of 70 N is used to move it toward the Earth?
Answer:
10 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
m is the mass
f is the force
From the question we have
[tex]a = \frac{70}{7} = 10 \\ [/tex]
We have the final answer as
10 m/s²Hope this helps you

Answer:
63.4 °C
Explanation:
If we assume the "fixed points" are 0 °C and 100 °C, then the thermometer reading as a function of actual temperature can be described by a linear equation that must have (0, -0.5) and (100, 106) as solutions. We can use these points in the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (106 -(-0.5))/(100 -0)(x -0) -0.5
y = 106.5x -0.5
Then, for x = 60, the thermometer reading is expected to be ...
y = 106.5×60 -0.5 = 63.4 . . . °C

TRUE or FALSE?If you are an astronaut slowly drifting away from the space station, you might be able to drift back to the station by throwing a 5-kg tool rapidly in the direction that you are traveling (away from the station).
Answer:
yes every action as an equal and and opposite reaction. if you throw a tool then it will give you a reaction and you will move back.
Explanation:
According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.
To understand it better:
Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.
So, if you as an astronaut in the described situation throw your tool in the direction that you are traveling (in the opposite direction of the space station), according to Newton's third law, you will be automatically moving towards the station

A gas has a pressure of 150 kPa at a volume of 6 m3. Calculate the volume of the same mass of gas at a pressure of 425 kPa
Answer:
V2 = 2.12 m³
Explanation:
Given the following data;
Original pressure, P1 = 150 kPa
New pressure, P2 = 425 kPa
Original volume, V1 = 6 m³
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 150 * 6 = 425V_{2} [/tex]
[tex] 900 = 425V_{2} [/tex]
[tex] 900 = 425V_{2} [/tex]
[tex] V_{2} = \frac {900}{425}[/tex]
[tex] V_{2} = 2.12[/tex]
Therefore, the new volume of the mass of gas is 2.12 cubic metre.

A 20N bucket is accelerated upward out of a well, by a rope with a force of 75N. What is the acceleration of the bucket
Answer:
36.76m/s²Explanation:
Given
Weight of the bucket = 20N
Mass = Weight/acceleration due to gravity
Mass = 20/9.8
Mass = 2.04kg
Applied force = 75N
Get the acceleration
According to Newton's second law:
F = ma
a = F/m
a = 75/2.04
a = 36.76m/s²
Hence the acceleration of the bucket is 36.76m/s²

If a galaxy is located 200 million light years from Earth, what can you conclude about
the light from that galaxy?
A. The light will travel a total of 200 million kilometers to reach Earth.
B. The light will travel 200 million kilometers per second to reach Earth.
C. The light will travel a total of 300,000 kilometers to reach Earth.
D. The light will take 200 million years to reach Earth.
please help :(
Answer:
D
Explanation:
It's quite simple actually, you see, what light years basically means is how many years light takes to travel from point a to point b. So here it says that a galaxy is 200 million light years away. So since that light is 200 million years away, it would take 200 million years until that light reaches us.

Which shows increasing entropy?
mowing a lawn
folding clothes
falling leaves
washing dishes
Answer:
mowing a lawn
Explanation:
Entropy is the degree of disorderliness of a system. As a body moves from a more ordered state to a less ordered one, the entropy of the system increases.
Mowing a lawn is a typical example of increasing entropy. When a lawn is being mowed, the grasses becomes disordered without any fixed orientation. Folding a clothe is trying to bring orderliness to the clothe patterning. Washing dishes will make one arrange them in an ordered way. Falling leaves brings leaves together.Answer:
Falling leaves!
