If an object is consist of a negative acceleration or
composed of it, it is likely engaging of having to accelerate in a certain
direction in which the direction is heading towards the opposite of the
direction that is stated and that is likely to be a positive direction.

Answer:
force on larger piston = <em> </em>
Explanation:
we label the pistons as piston A and piston B
small piston A:
area = a
force = f
large piston B:
area = A
force = ?
<em>Pascal's law of pressure state that the pressure delivered to a liquid is transmitted undiminished to every portion of the fluid.</em>
we know that pressure = force ÷ area
pressure of piston A =
pressure of piston B =
obeying Pascal's law, the system pressures must be equal. Therefore
force on large piston (B) = F =<em> </em>
Answer : The energy of one photon of hydrogen atom is,
Explanation :
First we have to calculate the wavelength of hydrogen atom.
Using Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 10973731.6 m⁻¹
= Higher energy level = 3
= Lower energy level = 2
Putting the values, in above equation, we get:
Now we have to calculate the energy.
where,
h = Planck's constant =
c = speed of light =
= wavelength =
Putting the values, in this formula, we get:
Therefore, the energy of one photon of hydrogen atom is,
