Answer:
When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.
To find the solution to the problem, we would be using Planck's equation which is E = hv
Where:
E = energy
h = Planck's constant = 6.626 x 10-34 J·s
ν = frequency
Then, you’ll need a second equation which is c = λν
Where:
c = speed of light = 3 x 108 m/sec
λ = wavelength
ν = frequency
Reorder the equation to solve for frequency:ν = c/λ
Next, substitute frequency in the first equation with c/λ to get a formula you can use:
E = hν
E = hc/λ
But we are looking for the wavelength, so rearrange it more, then our final equation would be:
λ = hc / E
λ = (6.625E-34)(3.0E8 m/s) / (1.06E-13)
λ = 1.875E-12 m
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges.
Answer:
3054.32618 rad/s²
-431.1989 rad/s²
29080
Explanation:
Converting angular speed to rad/s
The average acceleration while speeding up is 3054.32618 rad/s²
The number of turns in the 1.2 seconds
The number of rotations in the 1.2 seconds is 349.99
Number of rotations in the 45 seconds
Average angular acceleration while slowing down -431.1989 rad/s²
Number of rotations while slowing down is 2479.16718
Total number of rotations is 349.99+26250+2479.16718 = 29079.15718 = 29080
