Explanation:
Let us assume that the given cylinder is 2.6 cm wide and its height is 3.1 cm. And, when piston is pushed down then the steady force is equal to 15 N.
Now, radius of the cylinder will be as follows.
r = 
= 
= 1.3 cm
or, = 0.013 m (as 1 m = 100 cm)
As, area of cylinder =
=
= 
Relation between pressure and force is as follows.
Pressure =
= 
= 25996 
Since, 1
= 1 Pa (as 1 kPa = 1000 Pa)
Therefore, P = 25996
= 25.99 kPa
= 26 kPa (approx)
Thus, we can conclude that pressure of the gas inside the cylinder is 26 kPa.
Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)

Explanation:
a) The expression for grating diffraction is
d sin θ = m λ
where d the distance between two slits, λ the wavelength and m an integer that represents the diffraction range
In this exercise we are told that the two spectra are in the same position, let's write the expression for each network
Network A
m = 1
sin θ = 1 λ / dA
Network B
m = 2
sin θ = 2 λ / dB
they ask us for the relationship between the distances, we match the equations
λ / dA) = 2 λ / dB
dB / dA = 2
b) let's write the equation of the networks
sin θ = m_A λ / dA
sin θ = m_B λ / dB
we equalize
m_A λ/ dA = m_B λ / dB
we use that
dB / dA = 2
m_A 2 = m_B
therefore the overlapping orders are

The gravitational force of attraction between two objects would be increased by "decreasing the distance between two objects"
Hope this helps!
Answer:
law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
Snell's law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. ... Snell's law asserts that n1/n2 = sin α2/sin α1.
