Answer: The centripetal force.
Explanation:
Refer to the figure below.
The centripetal acceleration of the object is
a = v²/r, directed toward the center of the circular path.
where
v = the tangential velocity
r = radius of the circular path
The centripetal force is
F = (mv²)/r
In the geocentric system, the Earth is considered to be the center of the solar system. The Moon, the planets, the Sun, and the stars all rotate around the Earth (which stays still), with uniform circular motion.
The organisms that belong to the soil food chain, yet do not obtain energy directly from plants are the <span>protozoa.</span>
Answer:
Explanation:
In order to solve this problem, we will need to draw a free body diagram of both situations (see attached picture).
So first, we need to find what the mass of the object is. We can do so by analyzing the horizontal movement of the first situation, so we get:
F=ma
so
m=2.34kg
next, we can analyze the second situation, we will start by analizing the vertical movement so we can determine the Normal force, so we get:
N=W
N=mg
N=3.79N
so now we can analyze the horizontal movement of the block, so we get:
I counted 8 protons so the atomic nun is 8
