C) a substance that flows
Measures angular displacement per unit time.
Answer:
See the explanation below.
Explanation:
Work in physics is defined as the product of force by the distance that the body travels in the direction of the force.
It can be represented by means of the following equation.

where:
W = work [J]
F = force [N]
d = distance [m]
In the given example the work is zero since the tree does not move, therefore the bear exerts a force on the tree. But there is no talk of movement of the tree, therefore the work is zero.
Answer:
false
Explanation:
As both parents contribute half of the new organism's genetic material, the offspring will have traits of both parents, but will not be exactly like either parent
To solve this problem we will apply the concepts of strain, flow stress and average flow stress to find the required data. We will start by calculating the Strain which is the logarithmic relationship between the longitudinal change. Later we will find the flow stress through the strength coefficient, the strain and the strain-hardening exponent. Finally with the found values it will be possible to find the average flow stress,
Now the strain is calculated with the logaritmic relation of the lengths.



With this value we can calculate the flow stress,

Here,
K = Strneght coefficient
n = Strainhardening exponent of brass


Finally the average flow stress will be given under the relation:
