No, empty plate doesn't get heated up in the microwave.
This is because the microwave oven heats the food by heating the water molecules that compose it.
This is achieved by increasing the vibration amplitude of the water molecules and their kinetic energy, therefore, increasing their temperature.
So, if the element that gets into the microwave oven does not contain water (as is the case of an empty paper plate), it will not heat up.
Therefore, this is all about the transfer of energy. This the principle on which microwave works. The transfer of heat energy from one object to the other increases the kinetic energy of the particle of the other object. But no object mean no heat energy transfer and the plate isn't heated.

When an object undergoing simple harmonic motion is farthest from it's equilibrium position kinetic energy is at its minimum.
What is simple harmonic motion?A motion in which the restoring force is directly proportional to the body's displacement from its mean position is known as a simple harmonic motion, or SHM. This restoring force always moves in the direction of the mean position.
A particle moving in simple harmonic motion accelerates as a(t) = - ω² x (t). Here, ω denotes the particle's angular velocity.
A constant exchange of kinetic and potential energy occurs in simple harmonic motion. Potential energy is at its peak and kinetic energy is zero at the distance from the equilibrium point that can be travelled the farthest. At the equilibrium point, the kinetic energy is at its peak and the potential energy is zero. The oscillating body has different values of kinetic and potential energy at other points in its motion.

The piston the student is standing on has a 0.22-times larger diameter than the piston the elephant stands on.
What is mechanical advantage of a hydraulic lift?Pascal's law is shown via the hydraulic system.In doing so, we are able to use a modest force on the small piston to generate a bigger force on the huge piston.At each piston, the ratio between the force and the area must be the same.The three practical tools that make use of Pascal's law are hydraulic presses, hydraulic lifts, and hydraulic brakes.Given parameters:
Mass of the student: m = 70 kg.
Mass of the elephant: M = 1200 kg.
Let the diameters of the piston the student is standing on and the piston the elephant is standing on are respectively d and D.
Using Pascal's law , we can write,
Force applied by the student's weight ÷ area of the piston the student is standing on = Force applied by the elephant's weight ÷ area of the piston the elephant is standing on.
⇒ 70 kg × g / π d² = 1200 kg × g / π D²

determine the maximum absolute values of the shear and bending moment. (round the final answer to one decimal place.)
Its maximum quantitative measurements of the bending moment and shear moments are equal at Mmax=0.8538kN.m.
What does the term "bending moment" mean?The vertical pressure or load given to a horizontal beam that causes bending is known as the bending moment. A ductility is a force that can change along a bar or beam's length and causes it to bend.
What different bending moments are there?Depending on the direction of the bending, there are two different types of bending moments: Positive or negative bending: The top fiber experiences compression, which prompts a tension (or tugging) response in the bottom fibre. Young's modulus for the beam's material is same in both tension and compression.
Briefing:
Take P = 3.5 kN
Taking moments about A,
RB×1=3.5×0.3+3.5×0.7+0.450
RB=3.95kN
Resolving the forces vertically,
RA+RB=3.5+3.5
RA+3.95=3.5+3.5
RA=3.05kN
3.05/x=3.95/(1-Xx)
x=0.436m
Mmax=3.05×0.436−3.5×0.136

monochromatic light falls on two very narrow slits 0.043 mm apart. successive fringes on a screen 6.10 m away are 8.8 cm apart near the center of the pattern.
In a double-slit interference experiment, the gap y of most of order m from the middle of the observed interference sample at the display screen is y = mλD/d.
where D = 6.10 m is the space of the display screen from the slits, and d = 0.043 mm = 0.043 × 10⁻³ m is the distance between the two slits.
The fringes at the display are 8.8 m apart from each other means the primary most (m=1) is placed at y=8.8 m apart from the middle of the sample.
Therefore, from the previous components we can locate the wavelength of the light:
λ = yd/mD = (8.8m) (0.043 × 10⁻³m) / (1) (6.10m) = 62.03 × 10⁻⁷m
And from the relationship between frequency and wavelength, c = λf, we are able to find the frequency of the light:
f = c/λ = 3 × 10⁸ m per sec / 62.03 × 10⁻⁷ = 0.048× 10⁻⁷ Hz

A 45.0 l sample of gas has a pressure of 975 torr at 35.2 c if the volume changes to 3.6 x 10^3 ml and the pressure changes to 2.61 atm what is the new temperature in ∘C?(8 points)
A 45 L sample of gas has a pressure of 975 torr at 35.2°C. The new temperature in °C is -222°C.
Given that, volume V₁ = 45 × 10³ ml
Pressure P₁ = 975 torr
Temperature T₁ = 35.2 °C = 35.2 + 273 = 308.2 K
V₂ = 3.6 × 10³ ml
P₂ = 2.61 atm = 1983.6 torr
T₂ = ?
The formula of combined gas law is P₁ V₁ / T₁ = P₂ V₂/ T₂
975*45 × 10³ / 308.2 = 1983.6*3.6 × 10³/ T₂
T₂ * 975 * 45 / 308.2 = 1983.6 * 3.6
T₂ = 1983.6 * 3.6 * 308.2 / 975 * 45 = 50.16 K - 273 = -222°C
