Answer:
Speed is 1.962*10^-3m/s
Explanation:
Given that
Mass of proton==1.67*10^-27
Acceleration due to gravity (g)=9.81m/s^2
Angle of inclination A=90°
Charge (q)=1.6*10^-19
Magnetic field (B)=5*10^-5T
From lorentz force
It can be seen that
F=w =mg=qvBsinA
We're Velocity (v)=mg /qBsinA
V=1.67*10-27*9.81/1.6*10^-19*5*10^-5*sin90
V=1.962*10^-3m/s
Answer:
if the resistor is fitted in series with the bulb , then the current flowing will be 0.15 A.....
if the resistor if fitted in parallel with the bulb ,
the current flowing will be 0.6 A
Explanation:
total potential difference = 1.5V
when resistors in series ,
total equivalent resistance is = 5 + 5 = 10 ohm
so current = 1.5 ÷ 10 = 0.15
when resistors in parallel ,
total equivalent resistance is = (5 × 5)÷(5 + 5) =2.5 ohm
so current = 1.5÷2.5 = 0.6 A
D) To overcome the electrostatic forces between opposing nuclei.
No work was done. Work is calculated by force/distance. If there isn't a distance change, no work has technically been done. I'm pretty sure that's right, at least! Hope it helps.
