Answer:
Explanation:
From free falling objects we know that height is equal to:
From the exercise we know that
Being said that, we can calculate how long would it take to the object to hit the ground knowing that the height at that point is 0
Solving the quadratic formula we got that
or
Since time can not be negative the logical answer is <u><em>t=5s</em></u>
So, the object hit the ground at 5s
Answer: 2Ω
Explanation:
Rtotal = 18Ω (ohms is represented by Ω)
Divide 18Ω into three equal parts
18Ω/ 3 = 6Ω
Now, if there are three resistors each with 6Ω connected in parallel, the equivalent resistance of the combination (Rtotal) of the circuit is as follows:
i.e 1/Rtotal = (1/R1 + 1/R2 + 1/R3)
1/Rtotal = (1/6Ω + 1/6Ω + 1/6Ω)
1/Rtotal = (1 + 1 + 1)/6Ω
1/Rtotal = 3/6Ω
1/Rtotal = 1/2Ω
To get the value of Rtotal, cross multiply
Rtotal x 1 = 2Ω x 1
Rtotal = 2Ω
Thus, the equivalent resistance of the combination is 2Ω
Answer:
While weight training will improve muscle strength and mass, the potential of a body to develop muscle is limited in part by genetic factors that are out of an individual's control.

Answer
What makes up a perfect planet? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon. Proportionate Ozone Layer and Light amount. According to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the Universe. This is the perfect planet. In the end a perfect planet includes SUSTAINBLE DEVELOPEMNT IN EVERY ASPECT OF LIFE!
Explanation:
Earth has trees and other planets don't have as much life as Earth so they don't have trees and wild life growing in them.
