The Ampere is the basic unit of electric current.
One Ampere means one coulomb of electric charge (6.24 x 10¹⁸ electrons)
flowing past you every second.
A Body Held Completely Immersed Inside a Liquid Experiences Two Forces: (I) F1, the Force Due to Gravity and (Ii) F2, the Buoyant Force.
Answer: Option (a) is the correct answer.
Explanation:
It is known that potential energy is the energy occupied by an object or substance due to its position is known as potential energy.
Therefore, more is the space occupied by an object more will be its position at a particular location. Hence, more will be its potential energy. On the other hand, smaller is the space occupied by an object, smaller will be the position holded by it.
Hence, smaller will be its potential energy.
Thus, we can conclude that for the given situation the statement, potential energy of the larger sphere is greater than that of the smaller sphere, is true.
The angle is 34.4°.
The radius of a circle and the central angle determine the length of an arc. We are aware that the arc length is equivalent to the circumference for an angle of 360 degrees (2π). As the proportion between angle and arc length is constant, we can say that:
L / θ = C / 2π
As circumference C = 2πr,
L / θ = 2πr / 2π
L / θ = r
We find out the arc length formula when multiplying this equation by θ:
L = r * θ
The arc length is equal to the radius multiplied by the central angle.
Radius of the circle, r = 2.70m
Length of the arc, L = 1.60 m
L = rθ
θ = L / r
= 1.60 / 2.70
= 0.6 rad
θ = (0.6 rad × 180° ) / π rad
= 34.4°
Therefore, the angle is 34.4°.
