The number of protons present in ATOM 1 is______
Ira Lisetskai [31]
Three protons and three electrons. The protons are the plus signs because protons are positively charged, and the electrons are the minus signs because electrons are negatively charged. Also, the neutrons are the circles. Neutrons are negatively charged

What is the diffrence between speed and avarege speed
Gekata [30.6K]
Speed is actually instantaneous speed, the speed an object is moving at that very instant.
But average speed is the total distance traveled divided by the total time.
Let's say you travelled 10 miles in 2 hours, your average speed would be 10 divided by 2, which is 10 miles / hr.

But during those 10 miles you may be accelerating, decelerating and be travelling 1 mile/hour and 20 miles/hour at another point. But your average speed would be total distance / total time. So your instantaneous speed can change throughout that period of time.

A warehouse has 5,000 drums of liquid chemicals. The foreman knows that 50 of these drums contain off-quality chemicals. Assume
IrinaVladis [17]
Given that the drum is replaced each time before sampling, the selections are independent events. Then, the probability of the combined event is the product of each probability: (50/5000) * (50/5000) * (50/5000) = (1/100)^3 = 0.000001

Steve wants to investigate the expansion and contraction of gases at different temperatures. He knows that at higher temperature
goblinko [34]

Answer: C. Gas particles move faster and farther apart at higher temperatures.

Explanation:

The options include:

A. the number of gas particles increases at higher temperatures

B. the number of gas particles decreases at higher temperatures

C. gas particles move faster and farther apart at higher temperatures

D. gas particles move more slowly and get closer together at higher temperatures

The statement that describes how the outcome (dependent) variable changes as a result of the changes made to the tested (independent) variable is that gas particles move faster and farther apart at higher temperatures.

It should be noted that the particles in the gases will collide more frequently with one another because of the shorter space that is between them.

The increase in the temperature will bring about a faster movement of the particles which in turn, brings about a rise in the diffusion rate and also the collision rate.
