Answer:
As the temperature increases, the kinetic energy of the particles increases.
Explanation:
When the temperature of the substance increases, the velocity increases which makes the movement of the particles to speed up. This causes the particles to increase. Therefore, as the temperature increases, the kinetic energy of the particles also increases.

Пояснение:
Используя уравнение движения S = ut + 1 / 2at², где;
U - начальная скорость = 15 м / с
а - ускорение
s - пройденное расстояние = 20м
t - время = 15 секунд
подставляем в формулу заданные параметры
20 = 15 (15) + 1 / 2a (15) ²
20 = 225 + 225a / 2
20 = 225 + 112,5a
20-225 = 112,5a
-205 = 112,5a
а = -205 / 112,5
а = -1,82
Отсюда ускорение -1,82
Answer:
1/4F
Explanation:
We already know thatThe electrostatic force is directly proportional to the product of the charge, from Coulomb's law.
So F α Qq
But if it is now half the initial charges, then
F α (1/2)Q *(1/2)q
F α (1/4)Qq
Thus the resultant charges are each halved is (1/4) and the first initial force experienced at full charge.
Thus the answer will be 1/4F
Which sentence from paragraph 4 most precisely explain the factors that determine the force of gravity?
- <em>"</em><em> </em><em>In</em><em> </em><em>other</em><em> </em><em>words</em><em>,</em><em> </em><em>these</em><em> </em><em>equations</em><em> </em><em>states</em><em> </em><em>the</em><em> </em><em>gravitational</em><em> </em><em>force</em><em> </em><em>between</em><em> </em><em>two</em><em> </em><em>bodies</em><em> </em><em>is</em><em> </em><em>proportional</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>product</em><em> </em><em>of</em><em> </em><em>their</em><em> </em><em>masses</em><em> </em><em>and</em><em> </em><em>inversely</em><em> </em><em>proportional</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>square</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>distance</em><em> </em><em>between</em><em> </em><em>them</em><em>.</em><em>"</em>
It's formula is g=GM/r²
