Answer:
False
Explanation:
The potential energy of a body increases by increasing the distance or elevation from a reference level (ground). This energy can be easily calculated by means of the following equation.
where:
m = mass [kg]
g = gravity acceleration [m/s²]
h = elevation [m]
As we can see the potential energy is proportional to height, that is, as the body increases its elevation, its potential energy increases.
<span>Because the droplets are conductors, a droplet's positive and negative charges will separate while the droplet is in the region between the deflection plates. You are given a situation that if a neutral droplet passes between the plates. The droplet's dipole moment will point at the center of the droplet.</span>
Answer:
a)0.120m
b)1.60s
c)0.625Hz
Explanation:
a)In this problem, initial displacement A=0.120m was displaced and released with zero initial speed.
The amplitude is the maximum displacement from equilibrium and it was maximum at the moment t=0.(∴The object goes from x=+A to x=-A and back to complete one cycle)
So the amplitude will be equal to the initial displacement A=0.120m
Therefore, the amplitude is 0.120m
b) movement from +A( max positive displacement) to -A (max negative displacement) took place during half the period of SHM
therefore,
0.800 s= T/2 ---> by further solving for T
T= 0.800 x 2
T=1.6 s
The period is 1.6 s
c) As we know that frequency is inversely proportional to the time period.
To find frequency:
f=1/T (∴T=1.6)
f=1/1.6
f=0.625Hz
therefore, the frequency is 0.625 Hz
I'll go with the answer A
