Answer from: vleverett444

Current in a conductor can be increased by Both of these (3rd Option )

Explanation:

Ohm's law states that the current is directly proportional to its applied voltage and it is inversely proportional to the resistance between the points.

Factors increasing the current in a conductor are:

As we know that resistance and conductance are inversely proportional to each other.As we increase the voltage across the two points, then the current in the conductor increases.As we decrease the resistance the current in the conductor increases.

Answer from: JaredO

THE CURRENT IN A CONDUCTOR CAN BE INCREASED BY BOTH INCREASING THE VOLTAGE ACROSS IT AND DECREASING ITS RESISTANCE.

Explanation:

Ohm's law states that the voltage or potential difference between two points is directly proportional to current passing through resistance and directly proportional to resistance.

According to ohm's law,

V = I * R

It means voltage is directly proportional to current and resistance.

current and resistance are inversely proportional to each other.

so from the above law it can be stated that current in a conductor can be increased by both increasing the voltage across it and decreasing its resistance.

Answer from: Quest

To use anything transparent

Answer from: Quest

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6 $\frac{m}{s^{2} }$

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
