The answer is; A
Airports are usually controlled by governments because they are the points of entry and exit into a country and therefore should have enough security and customs. The vulnerability of the industry also from factors such as terrorism and weather requires that the government regulates the industry to protect the country's interests.
First the velocity drops to zero in 1.2 secs. In those seconds it went upwards for 7.2 m, then it went from 87.2 to 0m. x-x0=v0*t+1/2*g*t^2 ergo t=sqrt(2x/g) that is 4.1761 s. Finally the total time required is 5.3761 s
<u>Complete Question:</u>
Which of the following electromagnetic waves carries the highest energy, and are most damaging to human?
A. Gamma Rays
B. Microwave
C. Radio-wave
D. Alpha Rays
<u>Correct Option:</u>
Gamma Rays carries the highest energy, and are most damaging to human.
<u>Option: A</u>
<u>Explanation:</u>
The waves of light and other forms of energy that radiate or travel from where they are originated is understood as electromagnetic radiation, and collectively represent electromagnetic spectrum. The gamma rays are dangerous sources of radiation with high energy. Its standard size is 0.000001 nm i.e. size of atomic nucleus diameter. It results from the degradation of atomic nuclei by radioactive means. It is made up of the smallest electromagnetic wavelength, and thus provides the highest photon energy.
I believe the answer is going to B I hope this helps and good luck
Answer:
The speed of molecule decreases and temperature also decreases
Explanation:
Kinetic energy of the molecules of a subsance is directly proportional to the temperature of molecule So as the kinetic energy decrease, temperature also decreases. decreses their speed.
