Answer:
The emf, electric field and the current in the wire are 10 V, 3.57 V/m and 1.43 A.
Explanation:
Given that,
Resistance = 7 ohms
Length = 2.8 m
Time t =0.2
We need to calculate the change in magnetic flux
Using formula of induced emf

Put the value into the formula


We need to calculate the electric field in the wire
Using formula of electric field



We need to calculate the current in the wire,
Using formula of ohm's law


Put the value into the formula


Hence, The emf, electric field and the current in the wire are 10 V, 3.57 V/m and 1.43 A.

On a Fahrenheit thermometer, the gas becomes 18 degrees warmer.
Answer:
It is one of the 7 diatomics
Explanation:
Br
I
N
Cl
H
O
F
^ these are the 7 diatomic molecules. Atoms of these elements exist as a molecule consisting of two covalently bonded atoms of the same element.
Simply put, for these elements, the diatomic state of the atom is much more stable than the unbound one.
