All electromagnetic waves travel in vacuum at the speed of c=3×10^8 m/s. Find the wavelength of microwaves of frequency 10^10 Hz

Physics

erica [24]3 years ago

Recall the wave equation, c=f\lambda where c is the speed of the wave (m/s), f is the frequency of the wave (Hz) and λ is the wavelength of the wave (m).

c=f\lambda \Rightarrow \lambda =  \frac{c}{f} so \lambda =  \frac{3 \times 10^8}{10^{10}} = 0.03 \text{m}

What is the length of a spring that has 450J of potential energy and a spring constant of 650N/m?
11111nata11111 [884]

Answer:

Δx = 1.2 m

Explanation:

The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²

Δx = √(2PS/k) = √(2(450)/650) = 1.17669... ≈ 1.2 m

The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.

Which of the following processes are Exothermic? I. Melting II. Sublimation III. Vaporization IV. Condensation
mariarad [96]

Answer: condensation process is exothermic. The correct option is IV.

Explanation: Exothermic reaction is a chemical reaction in which heat is released to the surrounding environment.

condensation is defined as a process by which a medium changes from gaseous phase into liquid phase. Using water molecules to illustrate, to transform water molecules to gaseous phase it requires the heat of vaporization to be overcomed. This same hear of vaporization needs to be given off when changing back to liquid phase.

The gravitational acceleration on Earth is 9. 8 m/s2. What is the weight of a car on Earth (to the nearest whole number) if it h
astraxan [27]

Hi there!

Recall the equation for weight.

W = Mg

W = Weight (N)

M = Mass (kg)
g = acceleration due to gravity (m/s²)


The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

W = 1360 * 9.8 = \boxed{13,328 N}
