Explain why people who eat only plants must eat a variety of plants in order to obtain all the nutrients they need

Because different plants contain different vitamins and minerals as well as different amino acids and our body needs a large variety of these in order to preform all the necessary chemical reactions taking place inside our body. Some vegetables are very rich in a certain vitamin but are lacking in another, like how oranges have plenty of vitamin C but not iron. Vitamins and minerals are used in your cells to speed up and allow pretty much any chemical reaction to occur, but each one helps with a certain process and cannot simply be replaced by a different vitamin. In addition, very few vegetables contain all of the essential amino acids that work as the building blocks for protein synthesis and the creation of enzymes, so if you are not getting all of these in your diet, it is very unlikely you are producing enough enzymes and as a result certain functions in your body could stop working altogether.

A mass m = 75 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 19.2 m and finally
dalvyx [7]

Answer:

The velocity is 19.39 m/s

Solution:

As per the question:

Mass, m = 75 kg

Radius, R = 19.2 m

Now,

When the mass is at the top position in the loop, then the necessary centrifugal force is to keep the mass on the path is provided by the gravitational force acting downwards.

F_{C} = F_{G}

\frac{mv^{2}}{R} = mg

where

v = velocity

g = acceleration due to gravity

v = \sqrt{2gR} = \sqrt{2\times 9.8\times 19.2} = 19.39\ m/s

Technician A says that the evacuation process will remove dirt and debris from the refrigerant system. Technician B says that th
GuDViN [60]

Answer: Technician B is right.

Explanation:

Evacuation process is used in refrigeration systems to remove moisture, air and non-profit condensable gases in order to achieve maximum function of the system.

vacuum pump is used to draw the sealed AC system into a vacuum. Evacuation of a refrigerant system also helps to maintain pressure, this is so as pulling a vacuum on the system is simply removing matter (mostly air and nitrogen) from inside the system so that the pressure inside drops below atmospheric pressure.
