Answer:
Change in momentum,
Explanation:
It is given that,
Mass of the basketball, m = 601 g = 0.601 kg
The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s
It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :
So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
Answer:
Explanation:
The equation of electric field is
E = 375 Sin(5.97 x 10^15 t + 1.99 x 10^7 x)
Compare with the standard equation
E = Eo Sin(ωt + kx)
(b) Amplitude of electric field, Eo = 375 V/m
Amplitude of magnetic field, Bo = Eo / c = 375 / (3 x 10^8)
Bo = 125 x 10^-8 Tesla
Bo = 1.25 x 10^-6 Tesla
(c) ω = 5.97 x 10^15 rad
2 x 3.14 x f = 5.97 x 10^15
f = 0.95 x 10^15 Hz
f = 9.5 x 10^14 Hz
Answer:
1) Force on top face
2)Force on the side face
Explanation:
a)
We know that
Pressure shall be calculated at a depth of (1-0.45) meters from the top of the water surface
Thus force is calculated as under
b)
The force on one of it's sides is calculated in the same manner except that the pressure is obtained at the centroidal level of the face of cube
Thus
