If all the sides are equal, then it is an equilateral triangle. This means after walking 100 meters, you had to turn 1/3 of 180 degrees (because that's what the interior angles of the triangle add up to).
So, 180 * 1/3 = 60 degrees.
We aren't done yet.
60 degrees is not the angle which you have turned from your path.
You turned 120 degrees to describe an angle of 60 degrees on the interior side.
The answer is B.
Explanation:
It is given that,
The separation between two parallel wires, r = 5.6 cm = 0.056 m
Current in both the wires is 2.65 A
(a) We need to find the magnitude of the force per unit length between the wires. It can be given by :

(b) As the current is in same direction, the wires will attract each other.
Answer:
300 m/s
Explanation:
2d = vt
v = 2d/t
v = 2×90/.3
v=300 m/s
d = distance
t = time
v = velocity/speed of sound
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity (
)
F= m* 9.8
or, m=
= 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
