Acceleration
On a velocity time graph, the y-axis is velocity, and the x-axis is time. So the slope is the change in velocity for every unit of change in time.
acceleration- the rate of change of velocity per unit of time.
hope this helps :)
Answer: The block of 0.4 Kg travel the same distance that the block of
0.2 Kg
Explanation: Considering the second newton law, we have the following
F= m*a
F= P*sin (θ) where θ is the angle for the incline
so mg sin (θ)= m*a
a=g sin(θ)
both block have the same acceleration in the inclined plane so travel the same distance independent of its mass.

Answer:
Part a)
T = 3.96 s
Part b)
T = 1.98 s
Part c)
T = 2.8 s
Explanation:
As we know that time period of spring block system is given as
T = 2.8 s
Part a)
If the mass of the block attached is doubled
then we will have
Part b)
If the spring constant is doubled
then we have
Part c)
If the amplitude is halved but mass and spring constant will remain the same
so here we know that time period does not depends on Amplitude
so we will have
T = 2.8 s
Answer:
Explanation:
wave length of light λ = 502 nm
screen distance D = 1.2 m
width of one fringe = 10.2 mm / 20
= .51 mm
fringe width = λ D / a , a is separation of slits
Puting the values given
.51 x 10⁻³ = 502 x 10⁻⁹ x 1.2 / a
a = 502 x 10⁻⁹ x 1.2 / .51 x 10⁻³
= 1181.17 x 10⁻⁶ m
1.18 x 10⁻³ m
= 1.18 mm .
