Answer:
The value is
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here
is the angular velocity which is mathematically represented as
![w =\frac{2 \pi }{ T}](https://tex.z-dn.net/?f=w%20%3D%5Cfrac%7B2%20%5Cpi%20%7D%7B%20T%7D)
substituting
for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as
![r = R + H](https://tex.z-dn.net/?f=r%20%3D%20%20R%20%2B%20H)
substitute
for R and
H
![r = 295.0 * 10^6 +3.60 * 10^6](https://tex.z-dn.net/?f=r%20%3D%20%20295.0%20%2A%2010%5E6%20%20%20%2B3.60%20%2A%2010%5E6)
=> ![r = 2.986 *10^{8} \ m](https://tex.z-dn.net/?f=r%20%3D%20%202.986%20%2A10%5E%7B8%7D%20%5C%20%20m%20)
So
Answer:
a) ![v_2=35.60ft/sec](https://tex.z-dn.net/?f=v_2%3D35.60ft%2Fsec)
b) ![h_2=45ft](https://tex.z-dn.net/?f=h_2%3D45ft)
Explanation:
From the question we are told that:
Weight ![W=100lbf](https://tex.z-dn.net/?f=W%3D100lbf)
Decrease in kinetic energy ![dK.E= 500 ft lbf](https://tex.z-dn.net/?f=dK.E%3D%20500%20ft%20lbf)
Increase in potential energy ![dP.E =1500 ft lbf.](https://tex.z-dn.net/?f=dP.E%20%3D1500%20ft%20lbf.)
Velocity ![V_1=40](https://tex.z-dn.net/?f=V_1%3D40)
Elevation ![h=30ft](https://tex.z-dn.net/?f=h%3D30ft)
![g=32.2 ft/s2](https://tex.z-dn.net/?f=g%3D32.2%20ft%2Fs2)
a)
Generally the equation for Change in Kinetic Energy is mathematically given by
![dK.E=\frac{1}{2}m(v_1^2-v_2^2)](https://tex.z-dn.net/?f=dK.E%3D%5Cfrac%7B1%7D%7B2%7Dm%28v_1%5E2-v_2%5E2%29)
![500=\frac{1}{2}*\frac{100}{32.2}(v_1^2-v_2^2)](https://tex.z-dn.net/?f=500%3D%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7B100%7D%7B32.2%7D%28v_1%5E2-v_2%5E2%29)
![v_2=35.60ft/sec](https://tex.z-dn.net/?f=v_2%3D35.60ft%2Fsec)
b)
Generally the equation for Change in Potential Energy is mathematically given by
![dP.E=mg(h_2-h_1)](https://tex.z-dn.net/?f=dP.E%3Dmg%28h_2-h_1%29)
![1500=mg(h_2-h_1)](https://tex.z-dn.net/?f=1500%3Dmg%28h_2-h_1%29)
![h_2=45ft](https://tex.z-dn.net/?f=h_2%3D45ft)
Answer:32 m/s/s
Explanation: since F=M*A, F=16N, M=0.5kg, A= F/M
A=16/0.5
A=32 m/s/s
They have positive charge and are located in the nucleus with neutrons
I am sure that your right because 600,000/10 is 60,000
