It depends on chemistry... A physical deformation to the Jell-O.
the model most likely represents the positions of earth, sun, and moon when there is: greatest difference between high and low tides
The high and low tides are created because of the combination of effects from the moon's gravitational forces with the sun's gravitational forces that affect the tide as the earth rotates
In transversal wave particles do not oscillate along the line of the wave propagation but oscillate up and down about their mean position as the wave travels.thus transverse wave is the one in which individual particles of the medium move about their mean position in a direction perpendicular to the direction of wave propprgation.
In longitutional waves the individual particles of the medium move in the direction parallel to the direction of the propprgation of the disturbance. The particles do not move from one place to another but the simply oscillate back and forth about their position of the rest.
HOPE IT HELPS.
Both B and C are correct.
B. Thomson did discover the electron.
C. Rutherford is one of the people credited for discovering the proton, besides Eugen Goldstein.
If you need only one answer, I'd pick B, though.
Answer:
-39.2m/s
Explanation:
Given that :
t = 4secs
g = -9.8m/s^2
v = ?
u = 0m/s ( since it was at rest )
V = u +at............. 1
Where v is the final velocity
a = -g = -9.8m/s^2 since the ball was dropped from a height which will eventually make it move against gravity
t = 4secs
Substitute the values into 1
v = 0 - 9.8×4
v = -39.2m/s
