Write this large number in scientific notation. Determine the values of Vm) and (n) when the following mass of the Earth is writ
hichkok12 [17]

Answer : The answer is, 5.97, 24

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

5000 is written as 5.0\times 10^3

889.9 is written as 8.899\times 10^{-2}

In this examples, 5000 and 889.9 are written in the standard notation and 5.0\times 10^3  and 8.899\times 10^{-2}  are written in the scientific notation.

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

As we are given the 5,970,000,000,000,000,000,000,000 in standard notation.

Now converting this into scientific notation, we get:

\Rightarrow 5,970,000,000,000,000,000,000,000=5.97\times 10^{24}

As, the decimal point is shifting to left side, thus the power of 10 is positive.

Hence, the answer is, 5.97\times 10^{24}

Now the answer is comparing to m.\times 10^n

So, m = 5.97 and n = 24

Thus, the answer is, 5.97, 24

If the mass of a moving object is doubled, which variable will also double? *
iVinArrow [24]

Answer:

potential energy

Explanation:

this is because potential energy= mgh

so when m= 2m

p.e. = 2 times the previous value

Therefore , When mass is doubled , Potential energy gets doubled. When mass is halved , Potential energy decreases by half.

If the volume of a container of gas remains constant, what will happen to the pressure of a gas if you increase the temperature?
Scorpion4ik [409]

Answer:

This example of the effect of volume on the pressure of a given amount of a confined gas is true in general. Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure.

Explanation:

Hope it helps
