Some things that causes friction between surfaces is a bike on a rocky road. The<span> action of one surface or object rubbing against another causing friction. Im not really sure if I helped But yeah..</span>
Army and Ellie left school at the same time.
Army lives farther than Ellie.
They arrived at their homes at the same time.
This means that Army travels faster than Ellie.
Time
Since the time is constant here, increasing the distance directly increases the speed.
Answer:
Kinetic energy and potential energy.
The term 'mechanical energy' refers to the sum of the kinetic energy and the gravitational potential energy of an object,
With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
Answer: rp/re= me/mp= 544 * 10^-6.
Explanation: To calculate this problem we have to consider the circular movement by the electron and proton inside a magnetic field.
Then the dynamic equation for the circular movement is given by:
Fcentripetal= m*ω^2.r
q*v*B=m*ω^2.r
we write this for each particle then we have the following:
q*v*B=me* ω^2*re
q*v*B=mp* ω^2*rp
rp/re=me/mp=9.1*10^-31/1.67*10^-27=544*10^-6
