The answer is option C.
For example, you are being chased by an elephant. The best way to outrun it would be to run in a zig-zag pattern. As the elephant has a large mass,it's mass would be resistant towards moving sideways,thus this proved that greater mass,greater inertia
M = mass of the ball A = 5.0 kg
m = mass of the ball B = ?
V = initial velocity of the ball A before collision = 20 m/s
v = initial velocity of the ball B before collision = 10 m/s
V' = final velocity of the ball A after collision = 10 m/s
v' = final velocity of the ball B after collision = 15 m/s
using conservation of momentum
M V + m v = M V' + m v'
(5.0) (20) + m (10) = (5.0) (10) + m (15)
100 + 10 m= 50 + 15 m
5 m = 50
m= 10 m/s
Given: Velocity of light c = 3.00 x 10⁸ m/s
Frequency f = 7.65 x 10⁷/s
Required: Wavelength λ = ?
Formula: λ = c/f
λ = 3.00 x 10⁸ m/s/7.65 x 10⁷/s
λ = 3.92 m
First we need to find the current flowing in the circuit. The three resistors are in series, so the equivalent resistance of the circuit is the sum of the three resistances:
Then we can apply Ohm's law to the whole circuit, to find the current flowing:
And now we can apply Ohm's law to the resistor of
to find the voltage drop across it:
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
