Answer:
greater
Explanation:
Let the initial velocity is u .
Acceleration due to gravity on earth, ge = g
Acceleration due to gravity on moon, gm = g / 6
Let the maximum height reached on earth is h and the maximum height reached on the moon is h'.
Use third equation of motion
At maximum height, the final velocity = 0.
For earth
0 = u^2 - 2 gh
h = u^2 / 2g ..... (1)
For moon
0 = u^2 - 2 g/6 x h'
h' = 6u^2 / 2g = 6 h (From (1)
So, the maximum height reached at moon is 6 times the maximum height reached at earth.
When light changes the medium it travels through it also changes speed. The speed in medium is given by formula:
Rearranging formual gives:
From this formula we can make conclusion that index of refraction is inversely proportional to speed of light in medium. This means that greater speed gives smaller index of refraction.
Answer: composition, its size and shape.
Explanation:
All objects have <u>a frequency that characterizes them</u>, which is called <u>natural frequency</u>. This means that if a disturbance or vibration is emitted near the object, it will begin to vibrate due to its natural frequency.
It should be noted that there are objects that have more than one natural frequency, and this depends on the composition of the object, its elasticity, its shape and size.
Answer: heat transfer
The heat is transferred from the hot coffee to the mug and air
