Answer:
A. Join glycerol to fatty acids
Explanation:
I majored in Physics.
Answer:
Amplitude
Explanation:
Amplitude is the vertical distance between the baseline to the crest or the horizontal diatance between crest and trough of a wave. Trough is the lowest point of the wave hence called the baseline while crest is the highest point of a wave. The horizontal distance between two successive waves is however called the wavelength and the product of wavelength and frequency gives the velocity of the waves. Note that amplitude has no effect on the velocity of the waves.
Given that.
F=3•i+4•j
And it from point (0,0)m to (5,6)m
dx=final position - initial position
dx=(5,6)-(0,0)
dx=(5,6)m
dx=5•i +6•j
Work done by the force is give by
W = F•dx
W=F•dx
Note that i•i=j•j=1 and i•j=j•i=0
Then,
W=(3i+4j)•(5i+6j)
Therefore,
W=3i•(5i+6j)+4j•(5i+6j)
W=15i•i+18i•j+20j•i+24j•j
W=15+0+0+24
W=39J
Then the work done by the force is 39 Joules
