B-Phylogenetic trees show evolutionary relationships among organisms.
C-Different species are grouped together.
D-Binomial nomenclature can show the most recent ancestor of two species.
The moon surface is visible to an observer on earth due to the gravitational force that attracts the moon to the earth. The more massive the body is, the more the smaller body is attracted to the larger body. We can only see the side of the moon due to the speed at which the moon rotates.
b. about 5 m/s2.
c. about 10 m/s2.
d. about 20 m/s2. E. about 50 m/s2.
We have that From the Question a ball is thrown straight up. At the top of its path its acceleration is
0 m/s2.
Option A
From the question we are told
A ball is thrown straight up. At the top of its path its acceleration is
a. 0 m/s2.
b. about 5 m/s2.
c. about 10 m/s2.
d. about 20 m/s2.
E. about 50 m/s2.
Generally
For a Ball thrown straight up at the top of its path where The gravitational force equals the force of the thrown,the Point where the ball is at equilibrium the Velocity of the ball is zero
Therefore
From the Question
A ball is thrown straight up. At the top of its path its acceleration is
a. 0 m/s2.
Option A

Explanation:
Total mass = 90 + 90 + 30 kg = 210 kg
Normal force = 210 kg ( 9.81 m/s^2) = 2060.1 N
Force of friction to overcome = normal force x coeff of static friction
F = 2060.1 x .15 = ~ 309 N to get the cart moving...
B. the splitting of atoms to release energy
C. natural underground reservoirs of steam and hot water
D. very hot minerals deep underground
The answer is; C
In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.
ANSWER
C. natural underground reservoirs of steam and hot water.

Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east.
