Answer:
1.2 inches
Step-by-step explanation:
Area of sphere
A = 4πr²
17.6 = 4(3.14)r²
17.6 = 12.56r²
Divide both sides by 12.56
1.4012738854 = r²
Take the sqaure root of both sides
1.1837541491 = r
Rounded
r = 1.2
We use the kinetic energy equation and substitute our data solving for the mass:
ke = (1/2)mv^2
m = 2*ke/v^2
m = 2*600/4^2
m = 1200/16
m = 75 kg
we can substitute directly because the units are homogeneus in the SI system: J, m/s, kg
They each go up by 5 :) 2+5=8 8+5=14 etc.
Answer:
30
Step-by-step explanation:
A right triangle is supposed to equal 90, if you add the other 31 + 29 you will get 60, having 30 as the last side.
