Answer:
The centripetal acceleration is
Explanation:
From the question we are told that
The radius is
The speed is
The centripetal acceleration of the pilot is mathematically represented as
substituting values
Answer:
I'm not sure but I think it's 4.5 v
<span>Length that is distance s = 4.00m
Speed of sound in air V = 343 m/s
Time for metal = 11.0ms = 0.011
Calculating the time t = s / V = 4 / 343 = 0.01166s
Time for the sound in the metal = 0.01166 - 0.011 = 0.00066 = 6.6 x 10^-4s
Speed of sound in metal Vm = 4 / 6.6 x 10^-4 = 6.060 x 10^3 m/s</span>
Answer:
Part a)
charge will move initially in +Y direction
Part b)
Part c)
Part d)
Explanation:
Part a)
Since electric field is in +Y direction so positive charge will move in the same direction
So charge will move initially in +Y direction
Part b)
Force due to electric field on the charge is given as
now work done to move it by 4.15 cm is given as
Part c)
As we know that work done by conservative force is negative change in potential energy
so we will have
Part d)
Work done by electric field = change in kinetic energy of the charge particle
here we have
Answer:
Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the rate of change of momentum
