what happens to the gravitational force when the distance between them stays the same and the mass of both objects is doubled
Dimas [21]

Answer:

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

A positive charge and a negative charge held a certain distance apart are released. as they move, the force on each particle:___
iVinArrow [24]

A positive charge and a negative charge held a certain distance apart are released. as they move, the force on each particle increases

The most common charge carriers are the positively charged proton and the negatively charged electron. The movement of any of these charged particles constitutes an electric current

<h3>What is a Charge ?</h3>

When there are more or fewer protons in an atom than electrons, the substance has an electric charge. Protons have a positive charge, while electrons have a negative charge. If a substance has more protons than electrons, it is positively charged; if it has more electrons, it is negatively charged.

  • The SI units for charge are ampere-second or coulomb. When one ampere of electric current goes through the conductor for one second, one coulomb of charge passes through it. Charge is denoted by the formula Q = I t.

A house at the bottom of a hill is fed by a full tank of water 5m deep and connected to the house by a pipe that is 110m long at
yawa3891 [41]

Answer:

a) p=964178.7\ Pa

b) h=98.2853\ m

Explanation:

Given;

  • depth of the water-tank, d=5\ m
  • length of the pipe, l=110\ m
  • inclination of the pipe from the horizontal, \theta =58^{\circ}

a)

Now the effective vertical height of the water column from the free surface of the water to the bottom of the pipe at house:

h=d+l.\sin\theta

h=5+110\sin58

h=98.2853\ m

Now the pressure due to effective water head:

p=\rho.g.h

where:

\rho= density of the liquid, here water

g= acceleration due to gravity

h= height of the liquid column

p=1000\times9.81\times 98.2853

p=964178.7\ Pa

b)

Now the height of water corresponding to this pressure will be the same as the effective water head by the law of conservation of energy.

h=98.2853\ m

A box of mass 7.7 - kg is accelerated from rest across a floor at a rate of 2.6 m/s2 for 18.5 s. Find the net work done on the b
mixer [17]

Answer:

Explanation:

The net work will change the kinetic energy

W = ½mv² = ½m(at)² = ½ma²t²

W = ½(7.7)2.6²(18.5²) = 8907.3985 = 89 kJ
