If you have an instrument that uses radiowaves with a frequency of 1.0x10^11 hz, what is the energy in joules and the wavelength in meters? use the equations c= av (i can't do the symbols) and e=hv

wavelength =  3×10⁻³ m

E = 6.63×10⁻²³ j

Explanation:

Given data:

Frequency of wave = 1.0 ×10¹¹ Hz

Wavelength of wave = ?

Energy of wave = ?

Solution:

speed of wave = wavelength × frequency

wavelength = speed of wave/ frequency

wavelength = 3×10⁸ m/s / 1.0 ×10¹¹ s⁻¹

wavelength =  3×10⁻³ m

Energy:

E = h. f

E = 6.63×10⁻³⁴ Kg.m²/s × 1.0 ×10¹¹ s⁻¹

E = 6.63×10⁻²³ Kg.m²/s²

Kg.m²/s² = j

E = 6.63×10⁻²³ j

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

idk what is it? is this a question that you know the answer or u dont
