A tomato is apart of the fruit family:) hope this helps!
Kinetic energy is proportional to the square of the speed. So when anything or anybody speeds up, its kinetic energy increases.
Answer:
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. For example, when you shuffle your feet across a carpet, you are creating many surface contacts between your feet and the carpet, allowing electrons to transfer to you, thereby building up a static charge on your skin. When you touch another person or an object, you can suddenly discharge the static as an electrical shock.
Explanation:
Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon. Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.

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:
gravitational force and outward pressure
Explanation:
The stars are very massive stellar objects, so they have a strong gravitational force, which drives the star to contract itself, but also in stars there are nuclear reactions such as fusion of hydrogen and other elements, that releases energy and creates a pressure from the center to the star exterior, an outward pressure that goes against the gravitational force. So when a star is stable these two forces exist in equilibrium or in balance, in which the star does not collapse by gravity or disintegrate by its outward pressure.
