Biology
1 answer:
Sphinxa [80]3 years ago
8 0

Answer:

Any time a body is in an environment that is colder than 98.6 F (37 C), heat is lost. And since the heat loss in water is 25 times faster than to air, this may occur fairly quickly.

7. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
nydimaria [60]
Kinetic energy = 0.5*M*V^2 

 Q7-
 
0.5*3*(2^2)= 6J

Q8a- 

0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.

Q8b-

at the max height, all the kinetic energy is converted to potential energy, 

gravitational potential energy is = M*g*h

that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:

First ball:
2kg*9.81(g)*10m = 196.2J

Second ball
4kg*9.81*10m= 392.4J

The second ball has more potential energy

What are the roles of covalent bonds and hydrogen bonds in the structure of DNA?
Vinil7 [7]
For the answer to the question above,
 <span>DNA is made up of two nucleotide strands. The nucleotides are connected together by covalent bonds within each strand. The sugar of one nucleotide forms a covalent bond with the phosphate group of another. The two strands themselves are connected by hydrogen bonds. The hydrogen bonds are found between the bases of the two strands of nucleotides. Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine. This is called complementary base pairing</span>
