moving the balls closer together
pumping more air into the soccer ball
putting the baseball in a plastic case
Explanation:
The gravitational force between the baseball and the soccer ball will increase if the moving balls are closer together, pumping more air into the soccer ball and putting the baseball in a plastic case.
According to Newton's law of universal gravitation "the force between two masses is proportional to the magnitude of their mass and inversely proportional the square of the distances between them". It is mathematically expressed as:
Fgravity = G
Where G is a constant called the universal gravitation constant.
M1 is the mass of particle 1
M2 is the mass of particle 2
r is the distance between them.
The force of gravity increases as their masses increase and also as the distance between the bodies reduce.
From the options:
Moving the balls closer together distance reducing
Pumping more air into the soccer ball mass increasing
Putting the baseball in a plastic case mass increasing

Answer:
The vacuum tube was replaced with transistor.
Explanation:
- The invention of semiconductor was very useful in making solid state transistor that allowed the production of small yet faster, cheaper, and more trusted and reliable computers.
- These solid state transistor is so often used that, it nearly replaced all the use of transistor.
- This replacement took place after the invention of semiconductor in the year around 1940.
- Vacuum tubes also known as thermionic tubes are not used anymore in computers and electronics.
The temperature of the water getting colder would cause the liquid in the thermometer to drop due to less heat being transferred from the water to the liquid, so the liquid molecules are closer than when they have high energy.
Answer:
It should be A
Explanation:
the amount of energy a population has should be based on how many people there are. if more people come into the population, the more energy it should have. if people leave the population, the less energy it should have.
