Sound is heard louder in newly furnished room ,why?

garik1379 [7]

A newly furnished room is likely to be more sparsely furnished, as clutter has yet to be introduced to the space. This means there will be more hard surfaces from which sound can bounce. This creates a noisier environment. The addition of throws, drapes, cushions, even tapestries will reduce reverberation.

Three cars, car x, car y, and car z, begin accelerating from rest, at the same time. car x is more massive than car y, which is

grigory [225]

When the net force exerted on each car is identical. after 10 seconds, the amount of momentum is same for all cars.

<h3>What is impulse?</h3>

The change in momentum is equal to the product of impact force applied while colliding and time for that impact.

F. t = m (Vf -Vi)

where, Vf is the final velocity and Vi is the initial velocity.

For car X, Fx x t = Mx Vx

For car Y, Fy x t = My Vy

For car Z, Fz x t = Mz Vz

The force applied is same for all and the the time is also same equal to 10 seconds. The impulse is same for all the cars.

Thus, the three cars have same momentum.
