These are adenine and guanine.
Purines adenine and guanine are double ringed structures that make up DNA. Purines have a characteristic double-ring structure composed of carbon, nitrogen and hydrogen atoms.
Each of purine's rings contain two nitrogen atoms making up a total of four within the double ringed structure. The remaining five positions within the rings are occupied by carbon atoms. The purine ring is encircled by hydrogen atoms which can be replaced by other atoms or groups of atoms to form different purines.

Centripetal force is modeled by the equation:
F = MV^2/R
where
F = force
M = Mass
V = Velocity
R = Radius
I will assume the shark is swimming in a circle with a radius of 14 m / 2 = 7 m. The actual radius will be smaller, but I'll assume that the question is simply poorly worded. So we need to calculate the velocity of the shark. The circumference of the circle is pi*14m = 43.98229715 m. And since velocity is defined as distance over time, we have a velocity of 43.98229715 m / 80 s = 0.549778714 m/s.
Now substitute the known values into the equation for centripetal force.
F = MV^2/R
F = 681 kg * ( 0.549778714 m/s)^2 / 7m
F = 681 kg * 0.302256635 m^2/s^2 / 7m
F = 205.8367683 kg*m^2/s^2 / 7m
F = 29.40525261 kg*m/s^2
F = 29.40525261 N
Rounding to 2 significant figures gives a force of 29 Newtons.</span>
The answer would be (D.) uranus
Answer:
The ocean liner
Explanation:
Given that,
The mass of the bullet, m = 0.0014 Kg
The velocity of the bullet, v = 396 m/s
The mass of the ocean liner, M = 7.1 x 10⁷ Kg
The velocity of the ocean liner, V = 13 m/s
The kinetic energy is given by the formula,
K.E = 1/2 mv²
1) The kinetic energy of the bullet,
K.E = 1/2 x 0.0014 x 396²
= 109.775 J
2) The kinetic energy of the ocean liner,
K.E = 1/2 x 7.1 x 10⁷ x 13²
= 6 x 10⁹ J
Hence, the ocean liner has more kinetic energy.
