Answer:
Explanation:
Force on the electron due to magnetic field 's north component will be zero because both velocity of electron and direction of magnetic field are same .
Force due to downward component of magnetic field
= B q v where B is magnetic field , q is charge moving and v is velocity of charge
F = 5 .00 x 10⁻⁵ x 1.6 x 10⁻¹⁹ x 4 x 10⁷
= 32 x 10⁻¹⁷ N
acceleration = F / m where m is mass of electron
= 32 x 10⁻¹⁷ / 9.11 x 10⁻³¹
= 3.5 x 10¹⁴ m/s²
Answer:
Moment of Inertia, I = 0.016 kgm²
Explanation:
Mass of the ball, m = 0.20 kg
Length of the pitcher's arm, l = 0.28
Radius of the circular arc, r = 0.28 m
Moment of Inertia is given by the formula:
I = mr²
I = 0.20 * 0.28²
I = 0.20 * 0.0784
I = 0.01568
I = 0.016 kgm²
I believe that a light bulb releases visible light and a radio antenna releases a radio waves
