How many ohms of resistance must be present in a circuit that has 240 volts and a current of 15 amps?
PIT_PIT [208]

Answer:

16 ohms

Explanation:

V= I ⋅ R

where,  V  is the net potential difference in the circuit,  I  is the current in the circuit and  R  is the net resistance of the circuit.  

In this case,  V = 240  volts,  I = 15  amperes.

240 = 15 ⋅ R  

⇒ R = 240/ 15 = 16  ohms

How did doubling the pressure change the gas volume?
stiv31 [10]
<span>For an ideal gas, the product of pressure and volume equals a constant times the absolute temperature. If each of the temperature and pressure of the gas is doubled, the product of pressure and volume increases by a factor of 4, and the absolute temperature must increase by the same ratio.</span>

Neporo4naja [7]

Answer:

Vector quantity

Explanation:

What is a vector quantity?

-> A vector quantity has both direction and magnitude

What is scalar quantity?

-> S scalar quantity has only magnitude

[] Based on these definitions, 9.7 x 104 km East is a vector quantity because it includes a direction, East.

Have a nice day!
