Answer:
Magnitude of the force on proton = F = 1.1085 × 10^-15 N
Explanation:
Charge on proton = q = 1.60 × 10^-19 C
Velocity of proton = V = 4.0 × 10^4 m/s
Magnetic field = B = 0.20 T
Angle between V and B = θ = 60
We know that,
F = qVBsin θ = (1.60 × 10^-19)( 4.0 × 10^4)( 0.20)sin(60)
F = 1.1085 × 10^-15 N
Answer:
The temperature rise of the water is = 0.14 °c
Explanation:
Height = 60 m
Potential energy change ΔP =
ΔP = m × 9.81 × 60
ΔP = (588.6 × m) Joule
Since the Potential energy change is equal to the internal energy change or Enthalpy change.
ΔP = ΔH
Since ΔH = m × C × ΔT
⇒ ΔP = m × C × ΔT
Put all the values in above formula we get
⇒ 588.6 × m = m × 4184 × ΔT
⇒ ΔT= 0.14 °c
Therefore the temperature rise of the water is = 0.14 °c
Answer:
V, W, and Y.
Explanation:
For a particle in uniform circular motion, the velocity vector remains constant in magnitude, but it continuously changes its direction. The velocity is tangent to the circle. The velocity vectors are all the same length.

To compute the net effect of two waves, we use the superposition principle, and we can call the resultant wave "superposed wave".
We can rewrite the sentence as follows:
"<span>If the above two waveforms were sound waves, we would hear the superposed wave louder. If the above two waveforms were light waves, we would see the superposed wave dimmer."</span>
The tension in the cable when the craft was being lowered to the
seafloor = <span>7500 N - 1800 N = 5700 N</span>
