Answer:
F = 10 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = forces [N]
m = mass = 0.05 [kg]
a = acceleration = 200 [m/s²]
![F =m*a\\F = 0.05*200\\F = 10 [N]](https://tex.z-dn.net/?f=F%20%3Dm%2Aa%5C%5CF%20%3D%200.05%2A200%5C%5CF%20%3D%2010%20%5BN%5D)
Answer:
microwaves
Explanation:
Electromagnetic waves consist of waves of different wavelengths. Among the choices given, waves are ordered for increasing wavelengths as follows:
gamma rays --> ultraviolet waves --> infrared waves --> microwaves
So, microwaves are the waves with the longer wavelength among the given choices. This is the reason why they are used by the cell phone companies: in fact, since they have longer wavelengths, microwaves can travel longer distances without being absorbed by objects or obstacles, and so they are more reliable for broadcasting and telecommunications.
Answer:
The answer is D.
Explanation:
Just like how cold air falls and warm air rises the same is with water.
Also the places with the coldest water is the north and south pole. The equator is relatively always warm so yeah.
They should see if there are any sources of bias
Explanation:
The best way to ascertain the reliability of the claim in the article is to see if there is a source of bias.
A source of bias in the article can tell a lot about how reliable and trustworthy the article is. It will also give room to more research about the claim in the article from other sources.
It is possible for some elements of bias to be introduced into a set of observation due to preference and choices.
