Why is the law of gravity an example of a universal law? a Gravity is the attraction of any mass to any other mass. b Gravity is a force that affects everyone on Earth. c Gravity is the reason the Earth revolves around the sun. d Gravity is a force that exists between any two masses in the universe
Answers
The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
What is Newton's law of gravitation?
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
where, F - Force,
g - gravitational constant,
m₁ - mass of the object 1
m₂ - mass of the object 2
r² - distance between the two masses.
Gravitational attraction is along a line joining the centers of mass of these two bodies. The magnitude of the force is the same on each, consistent with Newton’s third law.
So, The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
Hence, Option D is the correct answer.

b. the distance a spring stretches has nothing to do with how much force is applied to it.
c. as the force on a spring increases, the distance it stretches increases.
d. as the force on a spring increases, the distance it stretches decreases.
Answers
Answer: option c. as the force on a spring increases, the distance it stretches increases.
Explanation:
Hooke's Law relates the force (F) applied on the spring and extension (x) of the spring:
F = - k x
Where, k is the spring constant.
as the force on a spring increases, the distance it stretches increases but it is limited by its elastic limit. The negative sign means that spring force is a restoring force which means that the stretch of the spring is in opposite direction to force.
c. as the force on a spring increases, the distance it stretches increases
current to follow?
Answers
Answer:
Series circuit
Explanation:
By definition series circuit is a closed circuit in which the flow of electric current follows only one path.
In a simple electrical circuit (which is a series circuit) where electric cell is the source of power, each component is connected in such a way that there is only one pathway current flows from the positive terminal(+) round to the negative terminal(-) via the external circuit.
Current having only one pathway to flow means that when one of the components is removed, there will be no current flow.
what is serap's momentum
what is the total momentum of the entire system?
Answers
1) David's momentum is 12,000 kg m/s east
2) Serap's momentum is 15,000 kg m/s east
3) The total momentum is 27,000 kg m/s east
Explanation:
1)
The momentum of an object is given by
where
m is the mass of the object
v is its velocity
In this problem, we have:
m = 600 kg is the mass of David+his dune buggy
is their velocity (taking east as positive direction)
Therefore, David's momentum is:
And the direction is the same as the velocity (east).
2)
Again, we can use the same equation:
where this time
m is the mass of Serap+dunebuggy
v is their velocity
In this problem,
m = 500 kg is the mass of Serap + dunebuggy
v = 30 m/s is their velocity (positive since it is also in the east direction)
Substituting, we find
And the direction is the same as the velocity (east).
3)
The total momentum of the entire system is given by
where
is David's momentum
is Serap's momentum
In this problem, we have the following data, found in the previous parts:
The two momentum have same direction (east), so we can simply add them together to find the total momentum:
And the direction is still East.
