Answer: 0.5 hour / 30 minutes / 1800s

Explanation: The problem can be expressed through the following equation:

v = d/t

Derive to find t:

t = d/ v

= 300 km /600 km/ h

= 0.5 hr

0.5 hr x 60 mins/ 1 hr = 30 mins

Or in seconds

30 mins x 60 s/ 1 min = 1800 s

Answer:

30 minutes

Explanation:

If the plane is going 600 km/h

divide the length and time and it would be half of that, so 300 km would take 30 mins.

Svetach [21]

Answer:

The process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO2) is an example of a solid that undergoes sublimation.

Calculate the wavelength of a photon of light having a frequency of 3.50 x 1015 Hz.
Aliun [14]

Answer:

Wavelength, \lambda=8.57\times 10^{-8}\ m

Explanation:

Given that,

Frequency, f=3.5\times 10^{15}\ Hz

We need to find the wavelength of a photon of light. The relation between frequency and wavelength is as follows :

c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3.5\times 10^{15}}\\\\\lambda=8.57\times 10^{-8}\ m

So, the wavelength of the light is 8.57\times 10^{-8}\ m.
