Answer:
Gold is not used for making electric wires because it is too rare, and too costlier than Copper. Silver and copper are used for making wires. Copper is almost used in electric lines
Answer:
Option A
Explanation:
From the question we are told that:
Mass
Velocity
Generally the equation for momentum for Ball A is mathematically given by
Initial Momentum
Final Momentum
Therefore
Generally the equation for momentum for Ball B is mathematically given by
Initial Momentum
Final Momentum
Therefore
Option A
Answer:
The magnitude of the acceleration is
The direction is north of east
Explanation:
From the question we are told that
The force exerted by the wind is
The force exerted by water is
The mass of the boat(+ crew) is
Now Force is mathematically represented as
Now the acceleration towards the north is mathematically represented as
substituting values
Now the acceleration towards the east is mathematically represented as
substituting values
The resultant acceleration is
substituting values
The direction with reference from the north is evaluated as
Apply SOHCAHTOA
substituting values
I have the exact same question, any chance you figured it out since you posted this?
Gauss law states that the electric flux through any closed
surface is proportional to the net electric charge inside the surface. This is
expressed mathematically in the form of:
Φ = Q / εo
Where,
Φ = the electric flux = unknown (which we have to find for)
Q = the net electric charge = 5.0 µC = 5 E-6 C
εo = the permittivity of free space = a constant value =
8.85 E-12 C^2 / N m^2
Plugging in the values
into the equation will result in:
Φ = 5 E-6
C / (8.85 E-12 C^2 / N m^2)
Φ = 564,971.75 Wb = <span>5.6 x
10^5 Wb </span>
