Answer:
Scalar quantities: a. Speed
b. Density
Vector quantities: a. Force
b. Displacement
c. Velocity
Explanation:
A vector quantity is a physical quantity that has magnitude and direction so force, displacement and velocity are considered vector quantities because they have magnitude and direction
A scalar quantity is a physical quantity that has magnitude and direction so speed and density are scalar quantities because they have magnitude only
Answer:
0.026 V
Explanation:
Given that,
Inductance of the coil, L = 6 mH
The current changes from 0.2 A to 1.5 A in a time interval of 0.3 s
We need to find the magnitude of the average induced emf in the coil during this time interval. The formula for the induced emf is given by :
So, the magnitude of induced emf is 0.026 volts.
From the things on that list, the copper wire has the least resistance ... unless it happens to be several miles long.
Scientists use models to help explain an idea, visualize hypotheses, and closely examine something (such as an atom).
Blue light has a shorter wavelength than does red light, and since it travels at the same speed (in vacuum) as red light, has a higher frequency. This gives it a higher energy per photon.
