Answer:
The combination, L = I / (m * R) , that appears in the equation for the period of a physical pendulum, is called radius of oscillations
Hope this helps :]
The absorption spectrum would have all the wavelengths of the light source but would have black lines where the two red and one orange lines were in the emission spectrum
Answer:
The answer is X
Explanation:
Cause the highest points will most likely have the most potential energy
Answer:
V = 3.54 m/s
Explanation:
Using the conservation of energy:

so:

where w is te weigh of kelly, h the distance that kelly decends, m is the mass of kelly and V the velocity in the lowest position.
So, the mass of kelly is:
m = 425N/9.8 = 43.36 Kg
and h is:
h = 1m-0.36m =0.64m
then, replacing values, we get:

Solving for v:
V = 3.54 m/s
I'm pretty sure it is true. (78% sure)
