100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s
Answer:
They both are part of electromagnetic radiation.
Radio waves have longer wavelength than visible waves.
Radio waves have lower frequency than visible waves.
Explanation:
V=d/t
v=speed
d=distance traveled
t=time taken
hope this helps
Answer:
a) Total mass form, density and axis of rotation location are True
b) I = m r²
Explanation:
a) The moment of inertia is the inertia of the rotational movement is defined as
I = ∫ r² dm
Where r is the distance from the pivot point and m the difference in body mass
In general, mass is expressed through density
ρ = m / V
dm = ρ dV
From these two equations we can see that the moment of inertia depends on mass, density and distance
Let's examine the statements, the moment of inertia depends on
- Linear speed False
- Acceleration angular False
- Total mass form True
- density True
- axis of rotation location True
b) we calculate the moment of inertia of a particle
For a particle the mass is at a point whereby the integral is immediate, where the moment of inertia is
I = m r²
