Can someone help me find what the “sin0=“ is for this

24/25

Step-by-step explanation:

here's your solution

=> perpendicular = 24

=> base = 7

=> hypotenuse = ?

=> firstly we need to find hypotenuse

=> h^2 = p^2 + b^2

=> h^2 = 24^2 + 7^2

=> h^2 = 576 + 49

=> h^2 = 625

=> h = √625

=> h = 25

now sin thita = perpendicular/hypotenuse

=> 24/25

hope it helps

10¹⁸ ergs

Step-by-step explanation:

From the question,

Using the expression

M = log(E/10¹³)................. Equation 1

Where M = Richter magnitude of earth quake, E = Energy released in ergs.

Given: M = 4.0

Substitute into equation 1 amd solve for E

4 = log(E/10¹³)

Log(E/10¹³) = (4×5)/4

Log(E/10¹³) = 5

E/10¹³ = 10⁵

E = 10⁵×10¹³

E = 10⁵⁺¹³

E = 10¹⁸ ergs
