sertanlavr [38]3 years ago
8 0

Answer:

m = 4

Explanation:

We have,

You apply a force of  600 N to the branch  which acts as a lever. It means it is input force, IF = 600 N

The rear of the truck  weighs 2,400 N. It means it is output force, OF = 2400 N

The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :

m=\dfrac{2400}{600}\\\\m=4

So, the mechanical  gain of the lever arm is 4.

Explain why people who eat only plants must eat a variety of plants in order to obtain all the nutrients they need
katrin2010 [14]
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.

The Lamborghini Huracan has an initial acceleration of 0.80g. Its mass, with a driver, is 1510 kg. If an 80 kg passenger rode al
irina [24]

Answer:

a = 15.1 g

Explanation:

The relation between mass and acceleration is given by :

m\propto \dfrac{1}{a}

If a₁ = 0.80g, m₁ = 1510 kg, m₂ = 80 kg, we need to find a₂

So,

\dfrac{m_1}{m_2}=\dfrac{a_2}{a_1}\\\\a_2=\dfrac{a_1m_1}{m_2}\\\\a_2=\dfrac{0.8g\times 1510}{80}\\\\a_2=15.1g

So, the car's acceleration would be 15.1 g.

A quick USB charger claims its output current is 1.97Amp. We know that the standard USB output voltage is 5V. What is the output
Arte-miy333 [17]

Answer:

Output power of the charger is 9.85 watts.

Explanation:

It is given that,

Output current of the USB charger, I = 1.97 A

The standard USB output voltage, V = 5 V

We need to find the output power of the charger. It can be determined using the following formula as :

P = V × I

P=5\ V\times 1.97\ A

P = 9.85 watts

The output power of the charger is 9.85 watts. Hence, this is the required solution.
