Answer:
is the rate of change of its position of an object with respect to a frame of reference, and is a function of time. Velocity is equivalent to a measure of an object's speed and direction of motion.

Answer:
a,b,c and d.
Explanation:
Of the following statements the correct are:
a) It is possible to induce a current in a closed loop of wire located in a uniform magnetic field by either increasing or decreasing the area enclosed by the loop.
b) It is possible to induce a current in a closed loop of wire without the aid of a power supply or battery.
d) It is possible to induce a current in a closed loop of wire by change the orientation of a magnetic field enclosed by the wire.
e) It is possible to induce a current in a closed loop of wire by changing the strength of a magnetic field enclosed by the wire.
Answer:
The energy stored is 1.4 x 10^-9 J.
Explanation:
Side of square, L = 10 cm = 0.1 m
Distance, d = 2 mm = 0.002 m
Electric field, E = 4000 V/m
The energy stored in the capacitor is
The capacitance is given by
Answer:
Their common velocity after collision is 3.6 m/s
Explanation:
Given;
mass of the first meatball, m₁ = 3.0 kg
initial velocity of the first meatball, u₁ = 6.0 m/s
mass of the second meatball, m₂ = 2.0 kg
initial velocity of the first meatball, u₂ = 0 m/s
let their common velocity after collision = v
Apply the principle of conservation of linear momentum for inelastic collision ;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
(3 x 6) + (2 x 0) = v( 3 + 2)
18 = 5v
v = 18 / 5
v = 3.6 m/s
Therefore, their common velocity after collision is 3.6 m/s
