There’s force of friction/ drag that slows down a moving object, there’s also gravity pulling the wagon down which would help slow it down. Hope this helps good luck.
Answer:
Explanation:
6 waves in 12 seconds
The period of a wave is defined as the time taken by the wave to complete one oscillations.
Here, 6 waves are completed in 12 seconds
So, one wave is completed in 2 seconds
So, the period of the wave is 2 second.
frequency is defined as the number of waves completed in one second. It is the reciprocal of period of the wave.
frequency = 1 / 2 = 0.5 Hertz
Let the wavelength is λ.
f = 660 kHz = 660000 Hz
the relation for the wave speed and the wavelength and the frequency is given by
v = f λ
where v is the speed of wave = 3 x 10^8 m/s
So, 3 x 10^8 = 660000 x λ
λ = 454.55 m
Well first, how do we determine force?
The correct answer is
<span>C. The current in the battery and in each resistor is the same.
In fact, when resistors are connected in series, the current flowing through them is the same in each resistor. This is also equal to the current flowing in the circuit, so it is the same as the current flowing through the battery.</span>
Answer:
-0.4454 Joules
Explanation:
m = Mass of block = 2 kg
h = Height of extension = 17 cm = x
g = Acceleration due to gravity = 9.81 m/s²
Potential energy of the spring

The kinetic energy of the spring

In this system as the potential and kinetic energy is conserved from work energy equivalence we get

The work done by friction is -0.4454 Joules
