A meterstick is supported at each side by a spring scale. A heavy mass is then hung on the meterstick so that the spring scale o

n the left hand side reads four times the value of the spring scale on the right hand side. If the mass of the meterstick is negligible compared to the hanging mass, how far from the right hand side is the large mass hanging. (A)25 cm (B) 50 cm (C)67 cm (D)75 cm (E) 80 cm in

Answer:

80 cm

Explanation:

Suppose the large mass is at point A which is at length 'x' meter  from right, Since it is on meter stick so the length on left will be (1-x) meter .

Since the system is in equilibrium position

clock wise torque around point A= anti clock wise torque around point A

force on left side × distance from point A on left side = force on right side × distance from point A on right side

Since left side is 4 times more reading - it means four times force of tension is acting there as compared to right side !

Let force be F

then,

4F × (1-x)=F × x

==> 4(1-x)=x

==> 4-4x=x

==> 4 =5x

==> x= 4/5=0.8 meter = 0.8 × 100 cm = 80 cm

Two sound waves are traveling through the same medium. They have the same amplitude, wavelength, and direction of travel. If the
Sloan [31]

Answer:

Constructive interference

Explanation:

Here, the medium is same, same wavelength, same frequency, same amplitude and same direction of propagation.

Let the intensity of waves be I which is same for both

The formula for the net intensity is

I^{2}=I_{1}^{2}+I_{2}^{2}+2I_{1}I_{2}Cos\phi

where, Ф be the phase difference

So, I_{R}^{2}=I^{2}+I^{2}+2IICos6\pi

Here, IR is maximum so the interference is constructive in nature.

If we know the force, the distance, and the time we can calculate only power. work and power. only work. neither work or power.
scZoUnD [109]

Work = (force) x (distance)

Power = (work) / (time)

Knowing force, distance, and time, it looks like
you can calculate both <em>work and power</em>.

But that's not all !

-- <u>Speed</u> = (distance) / (time)

-- <u>Impulse</u> = change in momentum = (force) x (time)
