Answer & Explanation:
Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.
Crest: points A and E
Trough: points C and J
Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.
Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

Answer:
a. 5.0 x 10⁷ brown grains = 50 million
b. 5.0 x 10³ brown grains = 5000
Explanation:
The concentration of 2 % brown sand means we have for every 100 grains of sand 2 are brown.
We need to calculate the number of brown sand in the bucket as follows:
= 2.5 x 10⁹ billion grains of sand x (2 brown grains/ 100 grains of sand)
= 5.0 x 10⁷ brown grains
Likewise if the concentration of brown sand is 2.0 ppm, it mean that we have 2 brown grain per every million grains of sand.
= 2.5 x 10⁹ billion grains of sand x ( 2.0 brown grains/10⁶ grains of sand )
= 5.0 x 10³ brown grains
The answers make sense since a concentration of 1 part per million is ten thousandths of a 1 percent
Answer:
The pendulum will begin to swing in the direction of the unbalanced force
Explanation:
The action of an unbalanced force on a pendulum will cause the pendulum to go into oscillation.
It must be stated that an unbalanced force causes acceleration of an object, in the direction of that force. Hence, unbalanced forces always set an object in motion.
