Explanation:
Answer:Explain the symbols.
Explanation: Because it shows you what it is.
Explanation:
Inertia is related to only mass, not speed.
Since a jet plane has more mass than a car, it has more inertia.
Answer:
Mass, m = 1.31 kg
Explanation:
It is given that,
Density of iron,
Side of cube, a = 55 mm = 5.5 cm
We need to find the mass of the cube of iron. Mass per unit volume is called the density of the substance. It is given by :
m = 1314.36 grams
or
m = 1.31 kg
So, the mass of the iron cube is 1.31 kg. Hence, this is the required solution.
A magnet is an item or substance that generates a magnetic field. The broken pieces of the magnet will have 4 poles.
A magnet is an item or substance that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most remarkable property: a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and others.
When a magnet is broken into two pieces, it produces two complete magnets, each with its own north and south poles and the same orientation as the original.
For example, if you break a 12-inch bar magnet with N on the left end and S on the right end midway between the two ends, you'll get two magnets with N on the left end and S on the right end, as seen in the illustration below.
Hence, the broken pieces of the magnet will have 4 poles.
