The car has gravitational potential energy (Eg)
Eg = mgh
Eg = (53kg) (9.81N/kg) (14m)
Eg = 7 279.02 J
(And don't forget that an object going around a curve at a constant speed is also accelerating.)
I believe there are two reasons:
1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.
2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
Answer:
Explanation:
This does not violate Newton's 1st law because the net force would still be 0 in order to produce uniform motion (aka constant velocity). The other forces acting on the vehicles is air resistance which is non-zero. So we need car internal force to counter balance this force, which require extra gas for the car.
Answer:
Correct answer: There are four variables rather than two - The amount of charge q₁, the amount of charge q₂, the distance between the spheres and the relative dielectric permeability εr of the medium.
Explanation:
I assume you meant two spherical objects.
The force between two charged objects according to Coulomb's law is calculated by the formula:
Fc = 1/ (4 π ε₀ εr) · (q₁ · q₂) / d²
where :
- ε₀ is the dielectric permeability of the vacuum
- εr is the dielectric permeability of the medium
- q₁ the amount of charge of the first sphere
- q₂ the amount of charge of the second sphere
- d is the distance between the spheres

Acids are the EXACT OPPOSITE of bases, but they're both still deadly. Base (or basic/alkali) is something in everyday thinks like toothpaste, milk, etc. But too much intake of bases can harm you, and if water has too much alkali, the fish living in it can die. Acidic, on the other hand, is very effective. Acids are usually in oranges, sodas, even your stomach has acids in it. Too much acids can rot your teeth, can cause "heartburn", even can give you a stomachache.
