Answer:
Explanation:
|F-->1| = E-->1 x charge on proton
= 300 x 1.6 x 10⁻¹⁹
Magnitude of electric force on proton
|F-->1| = 480 x 10⁻¹⁹ N .
Inside lithium nucleus , there are three protons so charge on it
= 3 x 1.6 x 10⁻¹⁹ = 4.8 x 10⁻¹⁹ C .
Magnitude of electric force on lithium nucleus
|F-->Li| = E-->1 x charge on lithium nucleus
= 300 x 4.8 x 10⁻¹⁹
= 1440 x 10⁻¹⁹ N .
Electron has same charge as that possessed by proton so charge on electron = 1.6 x 10⁻¹⁹ C
Magnitude of force on electron
|F-->1| = E-->1 x charge on electron
= 300 x 1.6 x 10⁻¹⁹
= 480 x 10⁻¹⁹ N .
To find the rate of deceleration, subtract the initial velocity from the final velocity.
Answer:
A wave is a disturbance that carries energy from one place to another.
Explanation:
The answer is 0.04 this is the answer you walcome
The average fluid velocity in the pipe can be obtained by dividing the flow rate of the liquid by the cross-sectional area of the pipe.
Av velocity = Flow rate/Cross-sectional area
Given, flow rate of the liquid = 0.008 m³/s
Cross-sectional area = 
, radius of the pipe is 0.02 m.
Substituting the values we get,
Av velocity= 
= 6.36 m/s
Average velocity of the fluid is 6.36 m/s.
