Answer:
Both Thomson and Rutherford used charged particles in their experiments.
Explanation:
An Earth revolution is a trip around the sun in a closed path (relative to the sun).
The path is very nearly an ellipse with the sun at one focus, and a little less nearly a circle with the sun at the center.
One complete revolution takes roughly 365.24 days, and at that point, the Earth immediately begins another one.
We have a special word that we use to refer to that special period of time. In English, it's called a "year".
Answer:
![\tau=3.96\ ksi](https://tex.z-dn.net/?f=%5Ctau%3D3.96%5C%20ksi)
Explanation:
Given that
d= 1.5 in ( 1 in = 0.0254 m)
d= 0.0381 m
P= 75 hp ( 1 hp = 745.7 W)
P= 55927.5 W
N= 1800 rpm
We know that power P is given as
![P=\dfrac{2\pi N\ T}{60}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B2%5Cpi%20N%5C%20T%7D%7B60%7D)
T=Torque
N=Speed
![55927.5=\dfrac{2\times \pi \times 1800\ T}{60}](https://tex.z-dn.net/?f=55927.5%3D%5Cdfrac%7B2%5Ctimes%20%5Cpi%20%5Ctimes%201800%5C%20T%7D%7B60%7D)
T=296.85 N.m
The maximum shear stress is given as
![\tau=\dfrac{16 T}{\pi d^3}](https://tex.z-dn.net/?f=%5Ctau%3D%5Cdfrac%7B16%20T%7D%7B%5Cpi%20d%5E3%7D)
![\tau=\dfrac{16\times 296.85}{\pi \times 0.0381^3}](https://tex.z-dn.net/?f=%5Ctau%3D%5Cdfrac%7B16%5Ctimes%20296.85%7D%7B%5Cpi%20%5Ctimes%200.0381%5E3%7D)
![\tau=27.35\ MPa](https://tex.z-dn.net/?f=%5Ctau%3D27.35%5C%20MPa)
We know that 1 MPa =0.145 ksi
![\tau=3.96\ ksi](https://tex.z-dn.net/?f=%5Ctau%3D3.96%5C%20ksi)
Answer:
B. MASS & MATTER
Explanation:
Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.
