Option C is correct. It has a high frequency. Wavelength is inversly proportional to the frequency. For short-wavelength, the frequency will be high.
Describe the connection between wavelength & frequency?Frequency and wavelength have an inverse connection with one another. As a result, the wave with a high frequency should have a short wavelength.
For short-wavelength, the frequency will be high.

What is the role of greenhouse gases, movement of
energy around earth?
Explanation:
With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth.Energy from the sun heats Earth's surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents.Mrs. Fatima has a a small sports car that she uses to drop her kids off from school that has a mass of 5000 kg.

An empty gas balloon has a mass of 500 kg. The balloon is filled with 3000m^3 of helium gas, at standard temperature and pressure (STP). If the densities of air and helium, at STP are 1.3kgm ^ - 3 and 0.18 kgm^ -3 respectively. Calculate the resultant force acting on the balloon. [g = 10N / Kg]
The resultant force acting on the balloon is 10,400 N.
Resultant force acting on the balloonThe resultant force acting on the balloon is calculated by applying Newton's second law of motion as follows;
F = ma
where;
m is massa is accelerationMass of the helium gas = density x volume
= 0.18 x 3000
= 540 kg
Total mass of the balloon = 500 kg + 540 kg = 1,040 kg

what happens to heat energy after an object is cooled down lolololol asking for my bff
Answer:
Heat energy does not cool. Objects cool. Energy is not an object. Now, what happens when an object cools is that it gives off some of its thermal energy by one or more mechanisms: radiation, conduction, or convection. In radiation the energy escaped the object as electromagnetic waves - you see the red hot poker slowly dim as it cools, in conduction the energy is transferred Mechanically by the atoms of the hot object being in physical contact with those of the cool object and in convection the hot material moves to a cooler region where it gives up its heat energy by either radiation or conduction.

In a parallel circuit, what’s happens to the current through each resistor when the voltage is doubled?
A. The current is doubled
B. The current is decreased by half
C. The current remains constant
Answer:
A
Explanation:
Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)
This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.

What does Einstein's famous equation for nuclear energy, E=mc2, mean?
Mass and energy are produced in a nuclear reaction.
Mass and energy are destroyed in a nuclear reaction.
Some mass and energy are lost in a nuclear reaction.
Some mass is converted into energy in a nuclear reaction.
Answer:
1.It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
2.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
3.In nuclear reactions, mass is never conserved—some mass is exchanged for energy and energy for mass. Nuclear reactions take place in an atom's nucleus. In a spontaneous nuclear reaction, such as radioactive decay, mass is "lost" and appears as energy in the form of particles or gamma rays.
4.In a nuclear reaction, mass decreases and energy increases. The sum of mass and energy is always conserved in a nuclear reaction.
5.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
