Can you please help me with this physics question
erastova [34]

Answer:

See the answers below

Explanation:

We can solve both problems using vector sum.

a)

Let's assume the forces that help the diver dive as positive downward, and the forces that oppose upward, as negative

F_{resultant}=100+30-85+900\\F_{resultant}=845[N]

The drag force is horizontal d this way in the horizontal direction we will only have the drag force that produces the water stream.

F_{drag}=50[N]

b)

Let's assume the forces that propel the rocket upwards as positive and forces like the weight of the rocket and other elements as negative forces.

F_{resultant}=960+7080-7700\\F_{resultant}=340 [kN]

Label these parts on the wave below: Amplitude, Wavelength, Crest, Trough, Rest Position
Leviafan [203]

Answer:

Wavelength is the distance between from one crest to another crest or from one trough to another trough. The amplitude is the distance from the midpoint to the crest or trough. Crest is the highest point of the or a wave. Tough is the lowest point of the or a wave. Rest position is the position where it lies on the midpoint line.

Explanation:

I need a diagram to label these parts.

Which of these statements is true? controlled data produces valid experiments. controlled experiments produce valid data. valid
Brums [2.3K]

Each of the choices may be considered right depending on the use of context or on how terms are defined, but the one that is most correct is:

 

"Controlled experiments produce valid data"

 

Controlled experiments are experiments in which factors which are not the interest of the study or which are not being studied are controlled or accounted for in the design, so that resulting data are less likely to be caused by some anomaly or by some variable other than those being studied. In usual research scenarios it is not the data itself that is acted upon in the <span>experiment - it is the experiment itself, the factors and the physical processes that will eventually yield data.</span>
