Answer:
See below
Step-by-step explanation:
Part A
<em><u>Formula</u></em>
M = 2/3 * log(E/Eo)
<em><u>Givens</u></em>
M = ??
E = 2 * 10^15 joules
Eo = 10^4.4
<em><u>Solution</u></em>
M = (2/3) * log(2 * 10^15 / 10^4.4)
M = (2/3 ) log (7.96 * 10 ^ 11)
M = (2/3) * 11.901
M = 7.934
Part B
What the question is saying is that E/Eo = 10000
You don't have to figure out exact values.
M = 2/3 * log(10000)
M = 2/3 * 4
M = 8/3 or 2 2/3 or 2.66667
If you have choices, please list them.
Find the common denominator which is 4. Then, multiply denominator and numerator with 2. When you add it, don't change the denominator
1/4 + 2/4 =3/4
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Product to Sum Identities:
2 sin A · cos B = sin (A + B) + sin (A - B)
2 cos A · cos B = sin (A + B) + sin (A - B)
Given: cos A + cos B = 1/2 and sin A + sin B = 1/4
<u>Proof LHS → RHS</u>
LHS = RHS: 1/2 = 1/2
Answer:
128cm²
Step-by-step explanation:
A=½×b×h
