Answer:
Explanation:
Let the velocity of deuteron be v then force on it in magnetic field
Bqv , B is magnetic field and q is charge on deuteron . This force will provide centripetal force for circular path so
mv² / r = Bqv m is mass of deuteron and r is radius of circular path
v = Bqr / m
(.5 x 1.6 x 10⁻¹⁹ x 55.6 x 10⁻² )/ 3.34 x 10⁻²⁷
= 13.31 x 10⁶ m /s
Answer:
Explanation:
Impulse and Momentum
They are similar concepts since they deal with the dynamics of objects having their status of motion changed by the sudden application of a force. The momentum at a given initial time is computed as
When a force is applied, the speed changes to and the new momentum is
The change of momentum is
The impulse is equal to the change of momentum of an object and it's defined as the average net force applied times the time it takes to change the object's motion
Part 1
The T-ball initially travels at 10 m/s and then suddenly it's stopped by the glove. The final speed is zero, so
The impulse is
The magnitude is
Part 2
The force can be computed from the formula
The direction of the impulse the T-ball receives is opposite to the direction of the force exerted by the ball on the glove, thus
The correct answer to this is:
“Air traffic controllers”
<span>These people are the personnel who is responsible
for the safety, orderly, and swift flow of planes flying in and out of
airports using the global air traffic control system. They are generally
stationed in air traffic control centers and control towers on the airport
ground. They monitor the position, speed, and elevation of aircraft in their designated airspace visually
and by radar,
and give directions to the pilots by
radio.</span>

Answer:
If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
Explanation:
R₁ = Resistance of first resistor
R₂ = Resistance of second resistor
V = Voltage of battery = 12 V
I = Current = 0.33 A (series)
I = Current = 1.6 A (parallel)
In series
In parallel
Solving the above quadratic equation
∴ If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
