Best answer is D) groundwater
Caves generally form by the slow (very very slow) dissolution of soluble rock, such as limestone, which is dissolved by the acid in groundwater. Stalagmites and stalactites are evidence of this very slow dissolution process.
1) Vibrate Parallel to the direction of the wave's propagation
For a closed end we have odd harmonics.
fo, 3fo, 5fo, 7fo, 9fo, ....... fo = V/ wavelength. = V / 4L
Wavelength = 4L.
For a open end we have natural number harmonics.
fo, 2fo, 3fo, 4fo, 5fo, ....... fo = V/ wavelength. = V / 2L
Wavelength = 2L.
Answer:
According to Newton's second law of motion, an object with a heavier mass will have more acceleration than an object with a smaller mass if both objects are moving with the same speed.
Explanation:
F=ma
a=F/m
a∝1/m
mass of any object is inversely proportional to its acceleration.
hence proved, an object with a heavier mass will have more acceleration than an object with a smaller mass if both objects are moving with the same speed.
First we need to find the time in the air
d = 1/2gt^2 + vt
Since there is no inital vertical velocity
4.1 = 1/2 (9.8) t^2
8.2/9.8 = t^2
0.8367 = t^2
t = 0.9147s
Now we multiply by speed
7m/s x 0.9147s = 6.4m
