Answer:
b) one-third as great.
Explanation:
As we know that same heat is supplied in this experiment
so we will have
now we know that both are initially at same temperature
then their final temperatures are
now we have
so we have
so heat capacity of mystery metal is 1/3 times that of water
The magnetic field strength at point 1 in the figure will be 6.67 ×10⁻⁵ T.
<h3>What is magnetic field strength?</h3>The number of magnetic flux lines on a unit area passing perpendicular to the given line direction is known as induced magnetic field strength .it is denoted by B.
The magnetic field strength is found as;
In the formula,I denote current, and r denotes the distance between the point and the current carrying wire and magnetic field due to current in the bottom wire.
At point 1, the net magnetic field is found as the sum of magnetic field due to current in the top wire.
Hence, the magnetic field strength at point 1 in the figure will be 6.67 ×10⁻⁵ T.
