What is a frequency of a wavelength

1 answer:

3 0

Light is measured by its wavelength (in nanometers) or frequency (in Hertz). One wavelength. equals the distance between two successive wave crests or troughs. Frequency (Hertz) equals the number of waves that passes a given point per second. Hope this helped

A 120.0 kg crate is placed on a 15.00°

Citrus2011 [14]

F = 2820.1 N

Explanation:

Let the (+)x-axis be up along the slope. The component of the weight of the crate along the slope is -mgsin15° (pointing down the slope). The force that keeps the crate from sliding is F. Therefore, we can write Newton's 2nd law along the x-axis as

Fnet = ma = 0 (a = 0 no sliding)

= F - mgsin15°

= 0

F = mgsin15°

= (120 kg)(9.8 m/s^2)sin15°

= 2820.1 N

The fastest propeller-driven aircraft is the Russian TU-95/142, which canreach a maximum speed of 925 km/h. For this speed, calc

valentinak56 [21]

Answer:

The resultant displacement of plane = 1310.76 Km

Explanation:

Given that,

Speed of the plane = 925 Km/h

Therefore, in 1 hour plane travels 925 Km

From figure,

Displacement if it travels east for 1.5 h, AB = 1387.5 Km

Displacement if it travels north-west for 2 h, BC = 1850 Km

Angle formed between two displacement = 135°

The resultant displacement is given by the relation

AC² = AB² + BC² + 2 AB BC Cos θ

Substituting the values in the equations,

AC² = 1387.5² + 1850² + 2 x 1387.5 x 1850 x Cos 135°

= 1718095

AC = 1310.76

Therefore, the resultant displacement of plane is 1310.76 Km

Which form of electromagnetic radiation with a relatively high amount of energy is used to sanitize lab goggles?

alexdok [17]

Answer:

Gamma radiation.

Explanation:

Electromagnetic waves are waves produced with respect to the interaction of electric field and magnetic field. They can be arranged with respect to their increasing or decreasing wavelength to form a pattern called electromagnetic spectrum.

Gamma radiation can be used for sterilization purpose due to the fact that it has a relatively high amount of energy, and do not produce any characteristic radiation.
