An interglacial is a period of time that occurs between Ice Ages. It’s marked by warmer temperatures and milder climates. During
Korolek [52]

Answer:

The correct answer is - 43%.

Explanation: The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.

A severe thunderstorm dumped 2.4 in of rain in 30 min on a town of area 29 km2. What mass of water fell on the town? One cubic m
Alexus [3.1K]

Answer:

The mass of water is 1.7661\times10^{9}\ kg

Explanation:

Given that,

Area of town = 29 km²

Time = 30 min

Height = 2.4 inch

Mass = 103 kg

We know that,

1 m = 39.37 inch

So, 2.4\ inch =\dfrac{2.4}{39.37}

2.4\ inch=0.0609\ m

We need to calculate the volume

Using formula of volume

V=H\times A

Put the value into the formula

V=0.0609\times29\times1000^2

V=1766100\ m^3

We need to calculate the mass of water

Using formula of density

\rho=\dfrac{m}{V}

Put the value into the formula

1000=\dfrac{m}{1766100}

m=1000\times1766100

m=1.7661\times10^{9}\ kg

Hence, The mass of water is 1.7661\times10^{9}\ kg

If an object weighs 40N, calculate the mass (gravity = 9.8m/s^2)​
Elan Coil [88]

Answer:

4.08 kg

Explanation:

We can apply the Newton's second law of motion to find the mass of this object:

F=ma,

where m is mass, and a is acceleration, which is substituted by g here. Now, plugging given numbers in the equation, we have

40=m\cdot9.8.

Solving for mass, we have

m=\frac{40}{9.8}\\=4.08 \;\text{kg}.
