The label means that the bulb will consume 75 joules of electrical energy in 1 sec
Answer: 31.6ft
Explanation:
Check the attachment for the diagram.
According to the right angle triangle AEC, we will use Pythagoras theorem to get |AC|. Note that |AE| = |AB| - |CD|
that is 20ft - 10ft = 10ft
According to the theorem, the square of the sum of the adjacent side and the opposite side is equal to the square of the hypotenuse.
|AE|^2 + |EC|^2 = |AC|^2
10^2 + 30^2 = |AC|^2
100 + 900 = |AC|^2
|AC| = √1000
|AC| = 31.6ft
Therefore, the wire should be anchored 31.6ft to the ground to minimize the amount of wire needed.
Answer:
Compression- pushing together
Refraction- pulling apart
Wavelength- the length of the wave

I attached a free body diagram for a better understanding of this problem.
We start making summation of Moments in A,



Then we make a summation of Forces in Y,



At the end we calculate the angle with the sin.


Cleavage<span> is the tendency of a </span>mineral<span> to break along smooth planes parallel to zones of weak bonding. Fracture is the tendency of a </span>mineral<span> to break along curved surfaces without a definite shape. These </span>minerals<span> do not have planes of weakness and break irregularly.</span>
