Answer:
Explanation:
Given
Let us suppose police car and motorist travel in straight line and police car catches motorist after s distance
Distance travel by motorist
----1
Distance traveled by Police car


----2
from 1 & 2 we get

(a)Velocity of Police car after t sec



(b)time taken by police car is

(c)Distance travel by police car
In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
The answer is strong push. When you ride a bike, the pedals convert a vertical push from your legs into rotational motion for the wheels to turn.
Answer:
voltage across = 1.6 V
Explanation:
given data
resistance R = 57.61 Ω
capacitance c = 13.13 mF = 13.13 ×
F
inductance L = 196.03 mH = 0.19603 H
fixed rms output Vrms = 23.86 V
to find out
voltage across circuit
solution
we know resonant frequency that is
resonant frequency = 1 / ( 2π√(LC)
put the value
resonant frequency = 1 / ( 2π√(0.19603×13.13 ×
)
resonant frequency f = 3.1370 HZ
so current will be at this resonant is
current = Vrms / R
current = 23.86 / 57.61
current = 0.4141 A
and
so voltage across will be
voltage across = current / ( 2π f C )
voltage across = 0.4141 / ( 2π ( 3.1370) 13.13 ×
)
voltage across = 1.6 V
Answer: 25Hz
Explanation:
Given that:
Wavelength (λ) = 0.4m (the distance between the peaks of a wave is known as wavelength)
Frequency F = ?
Speed of wave V = 10 m/s
The wave frequency is the number of cycles which the wave complete in one second. It is measured in hertz, and represented by the symbol F
So, apply the formula V = F λ
10m/s = F x 0.4m
F = 10m/s / 0.4m
F = 25Hz
Thus, the frequency of the wave is 25 Hertz.
