Answer:
The wood's potential energy on the carpenter's shoulder is 150 J.
Explanation:
Given;
mass of the wood, m = 10 kg
height through which the wood was raised, h = 1.5 m
acceleration due to gravity, g = 10 m/s²
The wood's potential energy on the carpenter's shoulder is calculated as;
P.E = mgh
P.E = 10 x 10 x 1.5
P.E = 150 J
Therefore, the wood's potential energy on the carpenter's shoulder is 150 J.
Answer:
It increases proportionally
Explanation:
The gravitational force between the Earth and an object on its surface is given by

where
G is the gravitational constant
M is the Earth's mass
m is the mass of the object
R is the Earth's radius
In this problem, the Earth's mass is increased, while the diameter (and therefore, the radius) doesn't change. From the equation, we see that the gravitational force is directly proportional to the Earth's mass: therefore, if the mass is increased, the force will increase as well by the same proportion (for example, if the mass is doubled, the force will double as well)
Answer:
It is a gene!!
Explanation:
It is because RNA is referred to as a gene. Genes are contained in chromosones.
The correct answer is<span> number of oscillations in a given period of time
This is measured in what is called the Hertz measurement and the period of time is usually taken to be per second.</span>
