Apendulum on earth swings with angular frequency ω. on an unknown planet, it swings with angular frequency ω/ 4. the acceleration due to gravity on this planet is a pendulum on earth swings with angular frequency . on an unknown planet, it swings with angular frequency 4. the acceleration due to gravity on this planet is a. 16 g. b. 4 g. c. g/4. d. g/16 .

g / 16

Explanation:

T = 2π

angular frequency ω = 2π /T

=

ω₁ /ω₂ =

Putting the values

ω₁ = ω ,     ω₂ = ω / 4

ω₁ /ω₂ = 4

4 =  

g₂ = g / 16

option d is correct.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the correct choice is a .
