If the gap between them doubles, the gravitational pull will be reduced to one-fourth of its current strength.
The inverse of the square of the factor that affects separation distance is the factor that affects electrostatic force. Therefore, the electrostatic force is reduced by a factor of four when the separation distance doubles.The square of the distance between the two charges has an inverse relationship with the force's size. As a result, when the gap between two charges is doubled, the attraction or repulsion weakens and drops to one-fourth of its initial strength.The force is smaller the further apart the masses are. The gravitational force does not decrease by half when the distance between two masses is doubled because it is proportional to 1/d2, but rather by 1/4.

a horizontal force of 8,000 newtons is required to pull a 2,548 kilogram truck across the floor at constant speed across the road. what is the coefficient of kinetic friction?
The coefficient of kinetic friction is 0.314.
Friction is the force resisting the relative motion of sturdy surfaces, fluid layers, and material factors sliding towards each specific. There are numerous styles of friction: Dry friction is a strain that opposes the relative lateral movement of two stable surfaces in touch.
Calculation:-
Force = 8000 N
mass = 2548 kg
a = f/mass
= 8000 / 2548
= 3.14 m/s²
Force = μkN
N = mg
= 2,5480 N
μk(coefficient of kinetic friction) = Force / N
= 8000/ 2,5480
= 0.314
Friction is the shape of contact pressure. It exists between the surfaces that are in touch. The frictional force relies upon the character of the floor in contact.

What would happen to the gravitational force felt between two objects if the radius between them were doubled?.
The force of gravitational attraction is reduced by a factor of 4 when the separation distance between two objects is doubled (increased by a factor of 2).
What is gravitational force?The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity.
Greater gravitational forces will be used to attract heavier things since the gravitational force is directly proportional to the mass of both interacting objects. Therefore, the gravitational attraction between two objects grows as their respective masses do as well. The force of gravity between two objects is equal to their respective masses multiplied by two. If one of the items triples in mass, the gravitational pull between them will also triple.
What is radius?The radius of a circle is the separation between its center and circumference. Always, the diameter is twice the radius. As a result, the formula is created by multiplying the diameter by two.

Kareen weighs 800n and sits at a distance of 4m from the pivot of a seesaw. zaid weighs 1200n. where should zaid sit to make sure the seesaw is balanced
Zaid should be sit at 2.6 m from pivot to make sure the see-saw is balanced.
A force or force system can rotate an object. A moment is a rotational action of force. Moments act clockwise or counterclockwise around a point. The point you select can be any point on the object, but typically the pivot point is selected.
The question is also based on Moment . For the seesaw to be balanced the moment caused by the weigh 800N of Kareen must be equal and opposite to the moment caused by the 1200 N weigh of Zaid.
A moment formula is equal to M = F x d
where , M ---> moment in N-m units
F---> force in Newton
d---> distance in meters
firstly , we calculate the force (F) resulting from the mass of each person.
Use newton's 2nd law , F = m x a .
The moment of the Kareen can be calculated using M = F x d,
moment= 800 (force or weight) x 4(distance from pivot) so, M = 3200 N-m.
The moment of the zaid must be equal and opposite to 3200N , so we have
3200 (moment) = 1200(force or weight) x d (distance).
If we divide this equation by 1200 we get 3200/1200 = d
which gives the d = 2.6m.
Hence, Zaid must sit 2.6m from the pivot to balance the seesaw with the Kareen.

The Frictional Work output on crate is 27.468 J.
When the body is moved in the direction of the force, frictional force will produce positive work. Think of two blocks that are stacked on top of one another. A frictional force between the two blocks prevents the two blocks from sliding if the lower block begins to move slowly in one direction. In the same direction that the lower block is moving, this force acts on the upper block. Friction in this situation therefore produces positive work.Friction can actually do more harm than good. For instance, when a block is sliding over a rough surface, the frictional force acts in the opposite direction from the block's motion and attempts to stop it. The direction of the block's motion and the direction of the frictional force being in opposition to one another, the work done by friction is negative.V=2.80m/s W= VgtanxW= 2.80 x 9.81 x tan90W=27.468 JThe work done on crate by friction is 27.468 J.To study about Work output-

Only 10% of energy moves from one trophic level to the next for each level. The 10 percent rule refers to this. Due to this law, only around 10% of the energy contained in the plants that herbivores consume gets absorbed by them. Only 10% or so of the energy stored as biomass at one trophic level, such as primary producers, is typically transferred to the next trophic level, such as primary consumers.

v = ( 1.73 * 5.55 ) / ( 1.34 * 0.293 )
v = 9.6 / 0.39
v = 24.62 m / s
Therefore, the the magnitude of the velocity of the bar is 24.62 m / s
The given question is incomplete. The complete question is :
A 0.293m -long bar moves on parallel rails that are connected through a 5.55 Ω resistor, as shown in the following figure (Figure 1) , so the apparatus makes a complete circuit. You can ignore the resistance of the bar and rails. The circuit is in a uniform magnetic field 1.34T that is directed into the plane of the figure. At an instant when the induced current in the circuit is counterclockwise and equal to 1.73 A, what is the magnitude of the velocity of the bar?
