The moon is 230,100 miles from planet earth.
I hope it helps! good luck in chem!
F = ma
<span>where </span>
<span>F = frictional force </span>
<span>m = mass of the block = 1.4 kg (given) </span>
<span>a = acceleration of the block = 1.25 m/sec^2 (given) </span>
<span>Substituting values, </span>
<span>F = (1.4)(1.25) </span>
<span>F = 1.75 N </span>
<span>By definition, </span>
<span>F = (mu)(Normal force) </span>
<span>where </span>
<span>mu = coefficient of friction </span>
<span>Normal force = mg = 1.4*9.8 = 13.72 </span>
<span>Again, substituting appropriate values, </span>
<span>1.75 = mu(13.72) </span>
<span>mu = 0.128</span>
Answer:
Explanation:
q = Charge of proton = 
v = Velocity of proton = 
c = Speed of light = 
B = Magnetic field = 0.00687 T
= Angle = 
Magnetic force is given by
The magnetic force acting on the proton is
i dont know about this but im willing to help you even im a questioneer....
