Three resistors, A, B, and C, are connected in parallel and attached to a battery, with the resistance of A being the smallest a

FromTheMoon [43]

Answer:

Resistor A

Explanation:

Resistors A, B and C are connected in parallel to a battery of voltage represented by V.

Since they are in parallel, the same voltage, V, passes across the three of them.

And from Ohm's law, the voltage (V) through a resistor is the product of the current (I) flowing through it and the resistance (R) of the resistor. i.e

V = I x R

=> I = $\frac{V}{R}$

Therefore, assuming the values of the resistances of resistors A, B and C are A, B and C respectively,

(i) the current, $I_{A}$ through A is

$I_{A}$ = $\frac{V}{A}$

(ii) the current, $I_{B}$ through B is

$I_{B}$ = $\frac{V}{B}$

(iii) the current, $I_{C}$ through C is

$I_{C}$ = $\frac{V}{C}$

From the foregoing, it can be deduced that the current is inversely proportional to the resistance. Therefore, the higher the resistance, the lower the current. Consequential of this, the resistor that carries the highest current is the one with the smallest resistance, which is A

A small sphere hangs from a string attached to the ceiling of a uniformly accelerating train car. It is observed that the string

Dvinal [7]

Answer:

a=7.384 m/s^2

Explanation:

let T be the tension in the string, m= mass

and a= acceleration

from the FBD in the attachment we can write

Tcos37°= mg

Tsin37° =ma

dividing both the equations we get

tan37° =a/g

therefore a=g×tan37°

a= 9.81×0.7535 = 7.384 m/s^2

the magnitude of the acceleration a of the train = 7.384 m/s^2

What type of friction is the type of kinetic friction that is difficult to overcome

Dovator [93]

Answer:

Therefore, Static friction is the type of kinetic friction that is difficult to overcome.

Explanation:

Static friction is the frictional force acting between two surfaces which are attempting to move, but are not moving.

Kinetic friction is the frictional force acting between two surfaces which are in motion against each other.
