Centripetal Force, F = mv²/r
Where m = mass in kg, v = velocity in m/s and r = radius of curvature in m.
Centripetal Force, F = 2000 * 25² / 80. Use your calculator.
F = 15 625 N.
Explanation:
It is given that,
Voltage, 
De broglie wavelength in terms of voltage is given by :
m and e are the mass and charge on electron. So,
So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.
The answer is supposed to be during the summer in Richmond,
the angle of the sun at noon from the vertical is 14 degrees which is equal to
Richmond's latitude of 37.5 degrees minus Earth's slope of 23.5 degrees. While in the winter, the angle of the sun at
noon from the vertical is 61 degrees.
The answer would be D. It's D because if there was corruption and instability, how will we fund the project? If there was lack of resources, how will the house be completed? If there was a lack of education, how will buildings be able to be engineered?
