Answer:
Speed of moving clock is
=πr/(86400) m/s
Here,
m and s are SI units of distance and time respectively.
Explanation:
If
radius of circular clock= r
than,
total distance covered on clock=S=2πr m
here, m=SI unit of distance
and required time for covering the total distance=t= 86400s
speed of normal clock=
=S/t
=2πr/86400 m/s
As, moving moving clock is ticking half as fast as normal clock so,
speed of moving clock==/2
=2πr/(86400)*2 m/s
<em> =πr/(86400)</em> m/s
Explanation:
The separation between the interference fringes on the screen increases because
the distance of the screen from the slit is increased. Therefore option (a) is correct.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory.
Therefore option (b) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory. Therefore option (c) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory. Therefore option (d) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory.
Therefore option (e) is incorrect.

Below are the choices that can be found from other sources:
A. The marlin has more momentum.
<span>B. The salmon has more momentum. </span>
<span>C. Both have the same momentum. </span>
<span>D. Both have no momentum.
</span>
Velocity is speed. Momentum is the product of velocity and mass. Because the Marlin has a much greater mass that means that it's momentum would also be greater.
<span>Lets look at this. momentum = mass x velocity </span>
<span>lets say that velocity for both fish is at 2 meters per second </span>
<span>Marlin : momentum = 500 x 2 = 1000 </span>
<span>Salmon : momentum = 20 x 2 = 40 </span>
<span>Therefore the answer is A</span>

Answer:Protons interact in ways that electrons do not. ... Electrons are not affected by the strong force, and so they only get trapped by the electrical attraction to the nucleus which is much weaker in ionized atoms.</h2><h2 /><h2>
Explanation:Therefore it is easier for electrons to move away from one atom to another, transferring charge.</h2>
Answer:4.05 s
Explanation:
Given
First stone is drop from cliff and second stone is thrown with a speed of 52.92 m/s after 2.7 s
Both hit the ground at the same time
Let h be the height of cliff and it reaches after time t
For second stone
---2
Equating 1 &2 we get
