Answer:
Explanation:
<u>Uniform Acceleration </u>
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
It's known a train moves from rest (vo=0) to a speed of vf=25 m/s in t=30 seconds. It's required to calculate the acceleration.
Solving for a:
Substituting:
Answer:
Explanation:
Given
Wavelength of light
Screen is away
Distance between two adjacent bright fringe is
When same experiment done in water, wavelength reduce to
So, the distance between the two adjacent bright fringe is
Keeping other factor same, distance becomes
Answer:
The Pressure is 0.20 MPa.
(b) is correct option.
Explanation:
Given that,
Change in volume = 9.05%
{tex]\dfrac{\Delta V}{V_{0}}=0.0905[/tex]
We know that.
The bulk modulus for water
We need to calculate the pressure difference
Using formula bulk modulus formula
Hence, The Pressure is 0.20 MPa.
