What secondary color is made by mixing red and green in the rgb additive-color scheme for light?.
Explanation:
Looking at the placement of primary colors in the RGB color wheel, the mixing of the red and green colors will create Yellow secondary color.
The secondary color that is made by mixing red and green in the rgb additive-color scheme for light is Yellow.
What is secondary color?Red, blue, and some are primary colors. Primary colors cannot be mixed with secondary colors.
All other colors are derived from them. Secondary colors are created by combining two primary colors that are adjacent to each other on the color wheel. Orange, green, and violet are the secondary colors.
As an accent color, a secondary color can be combined with a primary color. The primary color remains dominant, but the secondary color is used in tandem to draw attention.
The sum of two primary colors of equal intensity yields a secondary color: cyan is green+blue, magenta is blue+red, and yellow is red+green.
Thus, the secondary color of red and green combination is yellow.

Calculate the electric force between these two electrons. The value of the Coulomb constant 9 × 10^9 N · m^2/C^2 and the elemental charge is 1.6×10^−19C. Answer in units of N.
The electric force between these two electrons will be 2.8 ×10⁻¹⁹ C. The concept of electric force is used in the given problem.
What is electric force?Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The given data in the problem is;
F is the electric force
K is the Coulomb constant = 9 × 10⁹ Nm²C²
q is the elemental charge = 1.6×10^⁻¹⁹ C
The electric force is found as;
[tex]\rm F=K\frac{Q_1Q_2}{r^2} \\\\ \rm F=9 \times 10^9 \frac{(1.6 \times 10^{-9} \times 1.6 \times 10^{-9}}{((2.82 \times 10^{-15}^2} ) \\\\ \rm F=2.8 \times 10^{-9}\ N[/tex]

The starting materials in a nuclear change have a total mass of 2.3465 × 10–27 kg. after the change, the resulting materials have a mass of 2.3148 × 10–27 kg. how much energy was released during the change? 2.85 × 10–12 j 2.08 × 10–10 j 2.11 × 10–10 j 8.56 × 10–4 j
The energy released during the nuclear change is 2.853*10^(-12) J.
What is Nuclear change?
A nuclear change -- involves changes in nuclear structure, such as fission (splitting) of a nucleus or an atom, or fusion (combining) of neutrons and protons to form heavier atoms
Given that,
Total mass
[tex]m=2.3465\times 10^{-27}\ kg[/tex]
After change , the mass of resulting materials
[tex]m'=2.3148\times 10^{-27}\ kg[/tex]
Using the Einstein's mass energy equation
[tex]E=mc^2[/tex]
The energy released during the change is given by
[tex]\Delta E=mc^2[/tex]
Where, [tex]\Delta m[/tex] is the change of mass in the process
c = speed of light
The change in mass
[tex]\Delta m=m-m'[/tex]
[tex]\Delta m=2.3465\times 10^{-27}-2.3148\times 10^{-27}[/tex]
[tex]\Delta m =0.0317\times 10^{-27}\ kg[/tex]
We substitute the value into the formula
[tex]\Delta E=0.0317\times 10^{-27}\times (3\times 10^8)^2[/tex]
[tex]\Delta E=2.853\ti,es 10^{-12}\ J[/tex]

A block is pushed against the spring with spring constant 15 kN/m (located on the lefthand side of the track) and compresses the spring a distance 5 cm from its equilibrium position (as shown in the figure below). The block starts at rest, is accelerated by the compressed spring, and slides across a frictionless track (as shown in the figure below). It leaves the track horizontally, flies through the air, and subsequently strikes the ground. The acceleration of gravity is 9.81 m/s
a) What is the speed v of the block when it
leaves the track?
Answer in units of m/s.
b) What is the horizontal distance x the block
travels in the air?
Answer in units of m
c) What is the total speed of the block when it
hits the ground?
Answer in units of m/s
Answer:
F = -K x = 15 kN/m " .05 m = .75 kN = 750 N
W = 1/2 K X^2 original potential energy of block

An apple is released from rest 500 m above the ground. Due to the combined forces of air resistance and gravity, it has a speed of 40 m s when it reaches the ground. What percentage of the initial mechanical energy of the apple-earth system was dissipated due to air resistance? take the potential energy of the apple-earth system to be zero when the apple reaches the ground.
The percentage of the initial mechanical energy of the apple-earth system that was dissipated is : 84%
Determine the percentage of the initial mechanical energy dissipatedGiven that
Potential energy = mgh = 0
= m* 9.81 * 500 = 0
= 4905 m J
Kinetic energy ( K ) = 1/2 mv²
= 1/2 * m * 40²
= 800 m
Next step : calculate the dissipated energy
dissipated energy = Potential energy - kinetic energy
= 4905 m - 800 m
= 4105 m
Final step : determine the percentage of the dissipated energy
= dissipated energy / potential energy
= 4105 m / 4905 m
= 84%
Hence we can conclude that The percentage of the initial mechanical energy of the apple-earth system that was dissipated is : 84%

Often times we think about insulation, we think about keeping cold items cold, such as drinks in an ice chest or the cool temperature in your home. But insulation also keeps things high! The same thermos that keeps your water cold keep your hot chocolate worm. How was that possible?
Answer:
So, insulation essentially works by creating a sort of barrier between the hot and the cold object. This barrier helps to reduce heat transfer by either reflecting the thermal radiation or by decreasing thermal conduction and convection from one object to the other.

Answer:
Resonances occur at:
OC OCOC OCOCOC OCOCOCOC OCOCOCOCOCλ
λ/4 3λ/4 5λ/4 7λ/4 9λ/4
A resonance occrurs at λ/4
Thereafter, resonance occurs every λ/2
The fifth resonance will occur at λ/4 + 2λ = 9λ/4
If λ / 4 = 10 m then λ = 40 m
9 λ / 4 = 10 m because the pipe is 10 m long
λ = 40 m / 9 = 4.44 m the fifth resonance occcurs at a wavelength of 4.44 m
f λ = c = 340 m/sec
