Answer:
7.00 m
Explanation:
Given:
v₀ = 2.00 m/s
v = 5.00 m/s
a = 1.50 m/s²
Find: Δx
v² = v₀² + 2aΔx
(5.00 m/s)² = (2.00 m/s)² + 2(1.50 m/s²)Δx
Δx = 7.00 m
If the temperature is high there is less water because it evaporates if it is cloudy it is more because it doesn't evaporate
Answer:
114.92749 keV
Explanation:
r = Radius of trajectory
m = Mass of electron = 
B = Magnetic field = 0.044 T
q = Charge of electron = 
The centripetal force and the magnetic forces are conserved

Velocity of first electron

Velocity of second electron

Total kinetic energy is given by

Converting to eV


The energy of incident electron is 114.92749 keV

c) The tangential speed of a point on the rim of the turn-table:




d) The tangential and normal components of the acceleration of the turn-table:



![a_{n} = (0.365\times 10^{-3}\,m)\cdot \left[(0.421\,\frac{rev}{s} )\cdot (\frac{2\pi\,rad}{1\,rev} )\right]^{2}](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%20%280.365%5Ctimes%2010%5E%7B-3%7D%5C%2Cm%29%5Ccdot%20%5Cleft%5B%280.421%5C%2C%5Cfrac%7Brev%7D%7Bs%7D%20%29%5Ccdot%20%28%5Cfrac%7B2%5Cpi%5C%2Crad%7D%7B1%5C%2Crev%7D%20%29%5Cright%5D%5E%7B2%7D)
