Answer:
The resistivity of the wire is
Explanation:
We have,
Length of a wire is 40 cm or 0.4 m
Diameter of a wire is 0.60 mm
Radius is 0.3 mm or 0.0003 m
Resistance of a wire is 1.5 ohm
Now we need to find the resistivity of the material of which it is made. The resistance of a wire in terms of its resistance, length and area is given by :
= resistivity
So, the resistivity of the wire is .
Answer:
1,365 miles
Explanation:
i multiplied 455 x 3 because it traveled 455 miles an hour for three hours.
Explanation:
Both slinky waves and seismic waves are mechanical waves. Mechanical waves requires a medium to travel. These are of two types i.e. transverse wave and longitudinal waves.
Slinky wave is transverse in nature. The medium particle move to and fro during wave propagation.
Seismic waves are longitudinal in nature. These waves moves in the form of compression and rarefaction. Seismic waves are of two types i.e. P waves and S waves.
Hence, we have concluded that both waves are mechanical waves.
