Answer:
Time = 6.243 years = (1.97 × 10⁸) s
Explanation:
Speed = (Distance)/(Time)
Time = (Distance)/(Speed)
Distance = 4.37 light years = 4.37 × c × years
Time = (4.37 c.years)/(0.7c)
Time = 6.243 years = (1.97 × 10⁸) s
Hope this Helps!!!
Answer: i think its local drive
Explanation:
Answer:
The magnetic flux through the coil is greatest when the plane of its area is perpendicular to the magnetic field
Explanation: from the formula magnetic flux @= BScos∆
At perpendicular ∆ will be zero making cos∆ =1
Answer:
E = 12.25 x 10³ N/C = 12.25 KN/C
Explanation:
In order to balance the weight of the object the electrostatic force due to the electric field must be equal to the weight of the body or charge. Therefore,
Electrostatic Force = Weight
E q = mg
where,
E = Electric Field = ?
m = Mass of the Charge = 5 x 10⁻³ kg
g = acceleration due to gravity = 9.8 m/s²
q = magnitude of charge = 4 μC = 4 x 10⁻⁶ C
Therefore,
E(4 x 10⁻⁶ C) = (5 x 10⁻³ kg)(9.8 m/s²)
E = 0.049 N/4 x 10⁻⁶ C
<u>E = 12.25 x 10³ N/C = 12.25 KN/C</u>
