Answer:
Fx = 32.14 [N]
Fy = 38.3 [N]
Explanation:
To solve this problem we must decompose the force vector, for this we will use the angle of 50 degrees measured from the horizontal component.
F = 50 [N]
Fx = 50*cos(50) = 32.14 [N]
Fy = 50*sin(50) = 38.3 [N]
We can verify this result using the Pythagorean theorem.
![F = \sqrt{(32.14)^{2}+ (38.3)^{2}} \\F = 50 [N]](https://tex.z-dn.net/?f=F%20%3D%20%5Csqrt%7B%2832.14%29%5E%7B2%7D%2B%20%2838.3%29%5E%7B2%7D%7D%20%5C%5CF%20%3D%2050%20%5BN%5D)
False. Energy in any form is a scalar quantity.
True
Explanation:
It is correct to say that the salinity of the oceans has been relatively constant throughout geologic time because salt is removed at the same rate it has been added.
Salinity is the amount of dissolved salt found in the ocean. It is the degree of saltiness of the ocean.
- The rate at which salt has been added into the ocean over the years through geologic time has been very constant.
- Most salts in the ocean comes from land.
- Also the rate it has been removed is fairly constant.
- The salinity of ocean has once been used to date the age of the earth.

Answer:
a delta
Explanation:
The landform produced at the location E where the Mississippi River enters the Gulf of Mexico is a delta.
A delta is a depositional landform where a smaller body of water enters into a larger one.
The Gulf of Mexico contains a larger body of water and as the Mississippi river enters into it, it splits up into many distributaries.
So, this feature is a delta.
