Answer:
The gravitational force is 
Explanation:
Given that,
Mass of large ball = 8.4 kg
Mass of small ball = 0.061 kg
Separation = 0.057 m
Gravitational constant 
We need to calculate the gravitational force
Using formula of gravitational force

Put the value into the formula


Hence, The gravitational force is 
Answer:
B. Parameter.
Explanation:
After inspecting all of 55,000 kg of meat stored at the Wurst Sausage Company, it was found that 45,000 kg of the meat was spoiled.
The data above is described as a parameter because the data describes the entire population (the meat). the difference between statistic and parameters are statistic is used to describe a sample whereas parameter is used to describe the population.
Most of the substances have higher density in solid state. When we heated solids it change its state to liquid. After a few minutes the liquid will boil and after that it will change to gas. Gaseous state of matter has the lowest density. From this we can conclude that density decreases with increase in temperature.
Note the point: Water has higher density in 4℃, at its liquid state
Answer: The proton speed = 3 × 10^5m/s
Explanation: The electric P.E change the proton if It can reach the positive plate.
The workdone
