<span>Magnetic field lines form circles that go around the wire.</span>
Answer:
Explanation:
Given length is
Circumference of a circle is given as:
a.But the circumference is equal to length of the wire. Therefore circumference as a function of is:
b.Area as function of
Area is calculated as
Rewrite the circumference equation to make r the subject of the formula.
To express area as a function of :-
Therefore area of circle as a function of is
Well first i found three they are silver cadmium and indium<span />
Answer:
After a nucleus with 85 protons undergoes alpha decay, it has 83 protons.
Explanation:
In an alpha particle there are two protons
In the given substance's nucleus, there are total of 85 protons
After the decay, the proton number reduce
The current proton number after decay is
85 -2 = 83
After a nucleus with 85 protons undergoes alpha decay, it has 83 protons.
Answer:
force = 1 × N
Explanation:
given data
automobile mass = 1200 kg
insect mass = 0.0001 kg
insect accelerated = 100 m/s²
to find out
magnitude of the force the insect exerts on the car
solution
we get here force the insect exerts that is express as
force = mass × acceleration ............1
put here value we get
force = 0.0001 × 100 m/s²
force = 1 × N
