Question is Incomplete, Complete question is given below.

Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.

A) Current is proportionate to the conductance of the circuit and precisely proportional to the voltage applied across the circuit.

B) Current is conversely proportional to the electrical tension of the circuit and corresponds to the resistance across the circuit.

C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.

D) Current is commensurate to the resistance of the circuit and directly proportional to the electric pressure applied across the circuit.

Answer:

C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.

Explanation:

Now Ohms Law states that, "So long as a physical state of a conductor remains the potential difference applied to the conductor is directly proportional to current flowing through it."

I ∝ V

V=IR also I=V/R

where R is the Resistance

Hence, From above equation we can say that Current increases when there is increase in Voltage but Current decreases as the resistance decreases.

Hence,Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.

• A plastic bag filled with air has a volume of
ratelena [41]

Answer:

The change in the mass of box = 0.01 kg

Volume of air in the polythene bag = Volume of air in the rigid box

Therefore, Volume of air in the box = 0.008 m^3

Now, Density = Mass/ Volume

=> Density = 0.01 / 0.008 = 1.25 Kg / m^3

What force causes weight? How is weight affected as an object moves farther away from the center of the earth?
stich3 [128]

Gravity affects weight of an object

Its weight reduces as it moves away from the center as gravity is strongest near the core and reduces as you move away

Lonnie pitches a baseball of mass 0.20 kg. The ball arrives at home plate with a speed of 40 m/s and is batted straight back to
suter [353]

Answer:

B) 20N.s is the correct answer

Explanation:

The formula for the impulse is given as:

Impulse = change in momentum

Impulse = mass × change in speed

Impulse = m × ΔV

Given:

initial speed  = 40m/s

Final speed = -60 m/s (Since the the ball will now move in the opposite direction after hitting the bat, the speed is negative)

mass = 0.20 kg

Thus, we have

Impulse = 0.20 × (40m/s - (-60)m/s)

Impulse = 0.20 × 100 = 20 kg-m/s or 20 N.s
