In this sense, I believe that we simply divide both currents.
Therefore, we do 16 / 2 = ... 8. And to check answer, we turn back to equation. 8 = voltage (x) (2) equals 16.
Answer:
I would saw B. I choose B because translational motion is an object that shifts between one place to another.
Answer:
A-18500J
B-232.5 rad/s
Explanation:
A- As the cylinder rotates through 1000rad, it sweeps a distance of
So the work, which is distance times force, of the tension done on the cylinder through that distance is
W = Td = 50 * 370 = 18500 J[/tex]
B- The torque that exerts on the cylinder by the tension is
To = TR = 50*0.37 = 18.5 Nm
As the cylinder is hollow, its moments of inertia is
The torque is generating an angular acceleration of:
The time it takes to go from rest to 1000 rad
Therefore the final rotational speed is
Explanation:
First, we need to calculate the constant force, that is, the ratio between the applied force and the rubber stretch due to the application of the force:
Now, we can know how far will an 18N force stretch the rubber. From (1):
The work done by the external force on the rubber is equal to its elastic potential energy:
Answer:
5.9 x 10⁻⁷m
Explanation:
Given parameters:
Frequency = 5.085 x 10¹⁴Hz
Speed of light = 3.0 x 10⁸m/s
Unknown:
Wavelength of the orange light = ?
Solution:
The wavelength can be derived using the expression below;
wavelength =
v is the speed of light
f is the frequency
wavelength = = 5.9 x 10⁻⁷m
