Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
Answer:
Gravity is the attraction between two objects that have mass. The amount of gravity is directly proportional to the amount of mass of the objects and inversely proportional to the square of the distance between the objects. Gravity is a force that increases the velocity of falling objects - they accelerate.
Explanation:
Since the connection is in series, the current divider can be used. It's mathematical expression is In = (It Rt) / Rn. If the value for is solved, power dissipation can also be solved using P = I^2 R.
I = 0.47 A
A. P = (0.47)^2 (5) = 1.11 Watts
B. P = (0.47)^2 (9) = 2 Watts
C. P = VI = 16(0.47) 4.24 Watts
Let m = the mass of the softball.
Then the mass of the basketball is 3m.
By definition, momentum = mass * velocity.
If both the softball and basketball move at the same velocity, v, then
Momentum of the softball = mv
Momentum of the basketball = 3mv
Answer: The momentum of the basketball is 3 times that of the softball.
