Sally and Maria hypothesized that earthworms lived only in dark, damp places. They measured a one-meter square in a shady spot n

ear a stream. They dug through the soil and collected earthworms. They collected 43 worms. They repeated the experiment in several locations, sunny and dry included. They found the most worms in the shady, damp plot near the stream. Several other groups of science students carried out the same experiment and got similar results. This is an example of

Based on the tug of war pictured below, what is the net force? –190 N 10 N –10 N 190 N.
umka21 [38]

Force is defined as the push or pull applied to the body. Its unit is Newton. The net force will be 10 N on the right side.

What is force?

Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

The given data in the problem is;

F₁ is forced by person 1 = 100 N

F₂ is forced by person 2= 90 N

Fₓ is the net force

Fₓ = F₁ -F₂

Fₓ  = 100-90

Fₓ= 10 N

Hence the net force will be 10 N on the right side.

To learn more about the force refer to the link;

Which of the following is a physical property of water?
photoshop1234 [79]
Hi there!

First of all, you have to pay attention to the question, and they are asking for something physical, and physical means to be seen on the outside.

The answer is A because you can clearly see that water is a liquid. Being a liquid is a physical property.

It wouldn't be B because I believe it would be a chemical property to react with many substances.

Hope this helps! :D

Explain why we have to observe stars and other astronomical objects from above Earth’s atmosphere in order to fully learn about
GarryVolchara [31]

Answer:

Explanation:

As per the spectrum range, it is important to observe the Sun and other astronomical objects from Earth's surface because they lie in the visible band of spectrum.

Earth's atmosphere absorbs ultraviolet light coming from the space thus helps us to know and learn about their properties.

If we place telescope in space, would be covered with water droplets thus making it useless to study about any object or to see them hence proper place such as Earth's atmosphere is well suited to observe stars and other celestial bodies.

When the volume of the gas is reduced, what change in property would be the most reasonable to expect?
STatiana [176]

Answer:

Two possibities: Increase in pressure or decrease in temperature.

Explanation:

There are two possibilities under the assumption that mass of the gas is conserved and, consquently, the amount of moles is also conserved, a reduction in the volume of the gas leads to an increase in pressure (Boyle's Law) and a decrease in temperature (Gay-Lussac's Law)
