What velocity is needed for a 2400 kg car to have the same amount of momentum as an 800 kg car?

Answers

Answer 1

Answer:

since velocity is directly proportional to momentum, the heavier car will need 2400/800 = 3 times the speed of the small car.

Answers

Answer: C is the answer

Explanation:

In the given diagram Portion C has the longest wavelengths.

What is the electromagnetic spectrum?

The electromagnetic spectrum is the range of all types of electromagnetic radiation. Electromagnetic radiation is a form of energy that travels through space in the form of waves. This energy is produced by the movement of electric and magnetic fields, and it includes a range of wavelengths and frequencies.

The electromagnetic spectrum includes a wide variety of types of electromagnetic radiation, ranging from low-energy radio waves to high-energy gamma rays.

The different regions of the electromagnetic spectrum include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Each region of the electromagnetic spectrum has its own unique properties, such as its wavelength, frequency, and energy.

For example, radio waves have long wavelengths, low frequencies, and low energies, while gamma rays have short wavelengths, high frequencies, and high energies. The different types of electromagnetic radiation have different applications in areas such as communication, medicine, and astronomy.

Therefore, The correct option is portion C having the longest wavelengths.
