How strong is a neutron star's gravity.
Answer:
About a thousand billion times! Because neutron stars are so dense, they have intense gravitational and magnetic fields. The gravity of a neutron star is about a thousand billion times stronger than that of the Earth. Thus the surface of a neutron star is exceedingly smooth; gravity does not permit anything tall to exist.
It's crazy strong.

While you push a box you begin to decrease the force you are exerting on the box. When will the box reach equilibrium?
A. When the force you are exerting on the box is equal to 0.
B. When Fyou on box = -Fbox on you.
C. When the force of the box becomes Fyou on box < Fbox on you
D. The box will never reach equilibrium.
The application of a force on the box overcomes the friction and causes the box to accelerate
While the force is decreasing, the box will stabilize;
B. When [tex]\underline{F_{you \, on \, box} = -F_{box \, on \, you}}[/tex]Reason:
Newton's third Law of Motion states that action and reaction are equal in magnitude and opposite in direction
When the box is pushed with a force, [tex]F_{you \, on \, box}[/tex], the reaction of the box of mass, m, is as follows;
[tex]F_{you \, on \, box}[/tex] = [tex]F_{friction}[/tex] + m × accelerationWhere;
[tex]F_{friction}[/tex] = [tex]-F_{box}[/tex] for example
The negative sign is due to the direction of the friction force, or [tex]F_{box}[/tex] is opposite to the direction of the applied force
When the force is decreased to F₂ = [tex]F_{you \, on \, box}[/tex], such that we have;
[tex]F_{you \, on \, box}[/tex] = [tex]-F_{box \, on \, you}[/tex] , which is the condition for equilibrium, and the net
force is zero and according to Newton's first law of motion, the box moves
at constant speed no acceleration
Therefore the box will reach equilibrium when;

A 55-kg person lands on firm ground after jumping from a height of 2.8 m.
Explanation:
What are you searching for?
Potential energy?
Answer:
3018.4
Explanation:
So this velocity just before reaching the ground, the final equals square root of two times G times H. So gs 9.8 m per second squared H is 2.8 m. So it gives the velocity of 7.41 m per second squared. That's the velocity right before touching the ground. So to find the impulse required to come to rest here, we just do mass times the velocity minus zero. So zero is the final momentum, final velocity zero. So that makes the final momentum zero. So we multiply the mass with the velocity before touching the ground and after. And subject zero. That's the momentum after touching the ground. So we multiply mass 55 kg. At 7.41 velocity we got 407.45. kilograms meters per second of impulse. we know that the force will be larger for stiff stiff flex compared to bend flex. Because the stiff flex. Bring the object to rest in a short amount of time and distance. So in part C, that's calculate for stiff flex. The stopping distance, Delta Y. Is 0.1 m. This one centimeter. So we can calculate the acceleration of the body when it comes to rest. From the moment it touches the ground. equals v squared over two times Delta Y. So we use the square is 54.88. The 7.41 square divided by two times 0.01 gives us an explosion of 2744 m/s square. So you multiply this acceleration by the mass to get the force so force equals mass times acceleration gives us a large force, 159 20 newtons. Then for bent legs, repeat the same process with a different delta Y, delta Y of 200.5 m. So that's 50 centimeters and calculate acceleration the same process. Just use a different value of delta Y. And we get as much smaller acceleration 54.88 m per second square. And the force experience would just be mass times acceleration. That gives us 3018.4 newton's a lot smaller than for stiff flex.
How mass and volume of matters are connected to density?
This is a physics question not maths
Answer:
An object's density is the ratio of mass to volume of an object. The mass is how much it resists acceleration when a force is applied to it and generally means how much of an object or substance there is. Volume describes how much space an object takes up.
Which area of astronomy does Kepler's laws address? (1 point)
A. The movement of asteroids in the solar system
B. The movement of the sun in relation to the planets.
C. The movement of planets within the solar system.
D. The movement of stars within galaxies.
Answer:
B
Explanation:
His law describes the orbits of planets around the Sun.
The area of astronomy that Kepler's laws address is the movement of planets within the solar system. The correct option is C.
What is Kepler's law?According to Kepler's first law, "all the planets revolve in elliptical orbits around the sun, with the sun at one of the foci."
Perihelion is the point at which the planet is closest to the sun, and aphelion is the point at which the planet is farthest from the sun.
Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, describe the orbits of planets around the Sun.
Kepler's laws of planetary motion represent a watershed moment in the transition from geocentrism to heliocentrism. They establish the first quantitative link between the planets, including Earth.
Thus, the correct option is C.

a ball thrown horizontally with the velocity of 20 m\s from a 20 m building .what is the time
Answer:2.02s
Explanation:
At the y component, the tract of the ball is free falling body. The initial velocity at y component is 0 m/s.
Height = 1/2 * g * t^2
20 = 1/2 * 9.8 * t^2
t = (20 * 2 / 9.8)^1/2, t = 2.02s

What is the Validity measures of a basketball bouncing
This study was aimed at testing the construct validity of the basketball basic motion skills test instrument (ITK GDBB). The research used descriptive method of 3 basketball experts in the city of Cimahi; 3 experts are the expert in basketball. The instrument used was the ITB GDBB developed by Silvy (2019) consisting of top passing, bottom passing, top service, bottom service, chest passing, bounding passing, overhead passing, and leading ball (dribbling). This instrument consists of 76 items that cover 4 domains in basketball, namely chest pass, overhead pass, bound pass, and dribbling. The validity method used the construct validity of different power types. For the reliability method, it used the Kuder Ricardson (KR) and Objectivity analysis. The results of the construct validity analysis of a total of 76 items show that the score is ranged from 0.67 to 1.00. The construct validity value of 71 items in the basketball game is in the high category (= 1.00), 5 items are in the sufficient category, the relativity score is ranged from 0.75 to 0.98, and the objectivity score is ranged from 0.89 to 0.95. The conclusion is that this test instrument can be used as a standardized basic motion skill test for standardized large ball games for validity in basic motion skills in basketball games for grade VII junior high school students.

What happens when acetate rubs with wool
When a Cellulose Acetate rod is rubbed with a woolen duster, friction occurs, rubbing loosely held electrons from the rod onto the duster. So, this time, the rod loses electrons. Since the Acetate rod now has fewer electrons than protons it has become positively charged. Hope this helps!
Answer:
The charge becomes positive.
Explanation:
When rubbed with cellulose acetate the charge of the fur/wool will become negative.
