A type of matter made up of a combination of elements is called a compound. for example table salt, is made up of two elements that by themselves are lethal but chemically combined cancel each other out there for becoming edible.
Answer:
That is, mechanical waves cannot travel through a vacuum. This feature of mechanical waves is often demonstrated in a Physics class. A ringing bell is placed in a jar and air inside the jar is evacuated. Once air is removed from the jar, the sound of the ringing bell can no longer be heard.
A perfectly elastic<span> collision is defined as one in which there is no loss of </span>kinetic energy<span> in the collision. Therefore, we just add the kinetic energies of each system. We calculate as follows:
KE = 0.5(</span>1.0 × 10^3)(12.5 )^2 + 0.5(1.0 × 10^3)(12.5 )^2
KE = 156250 J = 1.6 x 10^5 J -------> OPTION A
Rosalind Franklin, James Watson, and Francis Crick’s discovered the DNA's Double Helix.
<h3>What is DNA?</h3>
DNA is an abbreviation for deoxyribonucleic acid and it can be defined as the molecules that are found within cells, and they are saddled with the responsibility of storing genetic information in living organisms.
In 1953, James Watson and Francis Crick's used other scientists' work to create a model of DNA in that they used Rosalind Franklin's photo to help them determine that deoxyribonucleic acid (DNA) was a double helix.
Furthermore, the discovery of DNA's Double Helix by Rosalind Franklin, James Watson, and Francis Crick led to modern molecular biology, which has helped many scientists and researcher to understand how genes control the chemical processes in the body of a living organism.

Find the number of hours by dividing the distance by mph. The number of hours will be to the left of the decimal point:
250 miles / 65 mph
= 3.846153846
= 3 hours
2) Find the number of minutes by multiplying what is remaining from step 1 by 60 minutes. The minutes will be to the left of the decimal point:
0.846153846 x 60
= 50.76923076
= 50 minutes
3) Find the number of seconds by multiplying what is remaining from step 2 by 60 seconds. The seconds will be to the left of the decimal point:
0.76923076 x 60
= 46.1538456
= 46 seconds
So 3 hours 50 mins and 46 seconds
