Answer:
4 A
Explanation:
We are given that
I=12 A
We have to find the current flowing through each resistor.
We know that in parallel combination current flowing through different resistors are different and potential difference across each resistor is same.
Formula :
Using the formula
Substitute the values
Hence, current flows through any one of the resistors is 4 A.
Some types of storage tanks are exempt from the federal regulations on USTs, including
: A) tanks that store heating oil burned on the premises.
<h3>What are Underground Storage Tank Systems?</h3>
Underground Storage Tank systems are tanks along with the underground piping that has at least 10% of their total volume underground.
Some of the storage tanks that are exempt from the federal regulations on USTs are;
- Farm and residential tanks of 1,100 gallons or less capacity holding motor fuel used for noncommercial purposes.
- Tanks storing heating oil used on the premises where it is stored.
- Tanks of 110 gallons or less capacity.

The best reason for buckling of rail tracks on hot summer days is the thermal expansion or compressive forces acting on the rail tracks.
<u>Explanation:</u>
The rail tracks are composed of metals and they are rigidly connected with each other. If the materials used in construction of rail tracks are old, then there can be weakening of the track materials leading to decrease in their resistivity to thermal heat.
So this increase in temperature on hot days leads to compressive stress on the tracks which causes the tracks to expand and misaligned themselves.
Also the loosening of the ballast, ties and fasteners enhance the speed of buckling on hot summer days. Thus due to thermal expansion of the materials of the tracks, they buckle up as there is no space for desired expansion.
