Firstly , draw the path 2.3 to east and 4.1 to the north. you’ll get a right - angle triangle . the hypotenuse is the displacement.
to find the distance , use Pythagoras theorem.
let the displacement = c
c ^ 2 = 2.3 ^ 2 + 4.1 ^ 2
c = 4.7 km
then , you need to find the angle.
tan theta = 4.1 / 2.3
theta = 61 degree
i am sorry if my answer was wrong but i hope it helps you and you can understand it : )
Since here two bulbs are connected in a line without any branching between them
Also there is same current through out the circuit in both bulbs
So it is SERIES combination of the circuit
here in series
current remains same
so correct answer is
<u>B. Series</u>
Answer:
e = 30 V
Explanation:
given,
N = 30 turns
Area = 0.25 m²
angular speed = ω = 100 rad/s
Magnetic field = 0.04 T
maximum induced emf in the loop = ?
e = N B A ω
e = 30 x 0.04 x 0.25 x 100
e = 30 V
hence, the maximum emf induced in the loop is equal to e = 30 V
The answer is c or b because a chemical property reacts with oxygen and it can be boil at 00 degrees Celsius but it can float in water so the answer is b,c,d,e.
Answer:
Explanation:
The theory of propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be
10.5775 - 10.3005
= .2770 g
errors will be added ie in subtracted value we can find error to the tune of
.0002 + .0002 = .0004 g
So the subtracted value will be written as
.2770 ± .0004
