Answer:
if a uniform resistance wire is stretched till it's length becomes four times the the resistance of wire multiples by sixteen times as resistance is directly proportional to the
length of wire.

Answer:
12.0 Volt
Explanation:
Step 1: Given data
Resistance of the ohmic dipole (R): 100 Ohm
Intensity of current (I): 120 mA (0.120 A)
Step 2: Calculate the voltage (V) across this chemical dipole
To calculate the voltage across the ohmic dipole, we will use Ohm's law.
I = V/R
V = I × R
V = 0.120 A × 100 Ohm = 12.0 V
Answer:
Sodium sulfate(Na2SO4) is a salt
Explanation:
It is a neutralization reaction in which sulphuric acid (H2SO4) which is composed of sulfur, oxygen, and hydrogen. Sulphuric acid is strong acid reacts with 2 moles of Sodium hydroxide (in neutralization reaction 1 mole of sulphuric acid is equal to 2 moles of Sodium hydroxide) gives us 2 moles of water and sodium sulfate (Na2SO4) which is composed of sodium, sulfur, and oxygen.
Sodium sulfate (Na2SO4) is salt, when H2SO4 reacts with sodium hydroxide (due to hydrate) it will give us salt (Na2SO4)
yes
