Answer:
- 1100 J heat flows out
Explanation:
dW = - 1600 J (as work is done on the gas)
dU = 500 J
dQ = ?
According to the first law of thermodynamics
dQ = dU + dW
dQ = 500 - 1600
dQ = - 1100 J
As heat is negative so it flows out.
The image position is 13.9 cm from the mirror
Explanation:
To solve this problem, we can use the mirror equation:

where
f is the focal length
p is the distance of the object from the mirror
q is the distance of the image from the mirror
In this problem, we have:
f = 3.4 cm is the focal length of the mirror (positive for a concave mirror)
p = 4.5 cm is the position of the object (the tree)
Solving the equation for q, we find the position of the image:

When the ball on a spring is replaced by a smaller ball with half the mass : The period decrease by 29%
<h3>Calculate the Period </h3>
We will apply the formula below to calculate period
T =
where :
T₁ / T₂ =
where m₂ = m₁ / 2
Therefore :
T₂ =
= 0.71 T
Hence we can conclude that the period will decrease by 29% ( i.e 100 - 71 ).

This bifurcation is called a saddle-node bifurcation. In it, a pair of hyperbolic equilibria, one stable and one unstable, coalesce at the bifurcation point, annihilate each other and disappear.
<h3>What is a bifurcation equilibria?</h3>
- The mathematical study of changes in a family of curves' qualitative or topological structure, such as the integral curves of a family of vector fields or the solutions to a family of differential equations, is known as bifurcation theory.
- A bifurcation happens when a tiny, gradual change in a system's parameter values (the bifurcation parameters) results in an abrupt, "qualitative," or topological change in the system's behavior.
- This term is most frequently used to refer to the mathematical study of dynamical systems.
- Both continuous systems (represented by ordinary, delay, or partial differential equations) and discrete systems can experience bifurcations (described by maps).

Answer:
3.83×10⁻¹⁹ J
Explanation:
The energy of a photon can be found using the formula: E=hc/λ
- h is Planck's Constant which is approximately 6.63×10⁻³⁴
- c is the speed of light which we'll round to 3.00×10⁸
- λ is the wavelength of the photon. You typed 5200 but that's not even within the visible light spectrum's wavelength range, so I'm going to assume you meant 520 nm; or 5.20×10⁻⁷ m.
Plugging all that info in should give approximately 3.83×10⁻¹⁹ Joules of energy.
(You could get slight variations depending on what you chose to round up or down or not at all.)
