he reason would be straightforward in case you have complete the test already. The bottles have a undeniable volume of air interior them.. you have often happening that gases do strengthen in case of heating.So, the air interior the bottle in sunlight expands.. often, in case you don't have an go out course for the air, it would desire to develop the stress interior the bottle or if is extra suitable than a undeniable decrease.It may blow up the bottle too. As u would desire to have considered some bicycle tires explode while saved below warm sunlight.Here, even with the undeniable fact that, we are offering an get away course for the air interior the bottle via keeping a balloon above.So the elevated air escapes into the balloon thereby swelling it.While the balloon saved below would not have a lot variations to observe. Its truly an straightforward test to do..

One situation is force applied to a moving object in the direction of its motion. The second situation is force applied to a moving object in the opposite direction of its motion. The third situation of force creating can be force that is applied to an object in motion that comes from arbitrary directions.

To get this answer you need to follow the equation of KE=0.5*mv^2
But we don't have the m part in the equation. So just plug in the numbers to see which works best, though I can tell you before we do that the answer would be a.

As you may know, gravity, is a force of 9.8 m/s. And we want to get 9.8 Joules. So if we take a half a kg stone, release it at one meter, we get half of the normal gravity pull, 4.90 Joules. That means if we take half a kg stone and drop it at a doubled height, we get 9.8 Joules.

That is also to say that if we have a 1kg stone and drop it at one meter you will get the normal pull of gravity in Joules, 9.8J.

Be careful though, this does not mean if you drop a 1kg stone and a .5 kg stone the 1kg will hit first. This simply means that the 1kg stone will have twice the Joules that the .5kg stone has.

lubasha [3.4K]

The angular speed can be solve using the formula:
w = v / r
where w is the angular speed
v is the linear velocity
r is the radius of the object

w = ( 5 m / s ) / ( 5 cm ) ( 1 m / 100 cm )
w = 100 per second

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.
