Answer:
The value is
Explanation:
From the question we are told that
The mass of the external weight is
The height through which the mass drops is
The number of revolution made is
The diameter of the free moving piston is
The distance moved by the free moving piston is
The atmospheric pressure is
Generally the workdone by the external weight is mathematically represented as
=
=
Generally the workdone by the free moving piston is mathematically represented as
Here A is the cross-sectional area with value
So
=>
So
The net workdone is mathematically evaluated as
The negative sign shows that it is acting in opposite direction to
So
maximum allowed value of the speed in roller coaster is given as
now from kinematics we can say
here initial speed will be
acceleration is due to gravity
now we can use this to find the height
so maximum allowed height will be 20.4 m
A) R = 1 / ( (1 / R1)+(1 / R2)+(1 / R3) )
b) I = U / R
c) I1 = U / R1 ... etc.
Answer:
The wavelenght is λ= 6 * 10⁻⁴m.
Explanation:
v= 1500 m/s
f= 2.5 MHz = 2.5 *10⁶ Hz
λ=v/f
λ= 6 * 10⁻⁴ meters
Answer:
true
Explanation:
the wavelength of AM radio is 10 m whereas FM has 1 m
