There are organelles in the plant cell that the animal cell does not have. Plant cells have rigid cell walls and animal cells have flexible cell membrane. Plant cells contains chloroplasts, which is something animal cells don't have. Also, large, liquid filled vacuoles can only be found in plant cells, and they can occupy up to 90% of a cell's volume. By looking at the cell and see if they have any of these characteristics determines if it is plant cell or animal cell.
hope this helps.
Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams
No, the water is same but the thermometer scales are different
as we know c/5 = f-32/9 where c=Celsius and f=Fahrenheit. (this is the relation between them)
so, 100/5=212-32/9
which means 20=180/9
Answer:
a.241.08 m/s b. 196 Hz c. 392 Hz
Explanation:
a. Determine the speed of waves within the wire.
The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.
Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have
v = 2Lf/n
substituting the values of the variables into v. we have
v = 2 × 1.23 m × 588Hz/6
v = 241.08 m/s
b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.
The first harmonic is obtained from f when n = 1,
So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz
c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz
