1. none of the above, because the ball must go inside the net
5. shooting
6. none of the above. the only skill that the goalie has that the rest dont have is using his hands to stop the ball from getting into the net
7. heading. if done incorrectly can seriously be dangerous
8. dribbling

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>

Two closed organ pipe gives 4 beats when sounded together at 5°C. Calculate the number of beats in 35°C

Gre4nikov [31]

Answer:

The number of beats is 10.58 in 35°C.

Explanation:

The beat frequency is given by : f₁-f₂

At 5°C, f₁-f₂ = 4

We need to find the number of beats in 35°C.

The frequency in a standing wave is proportional to $\sqrt T$ .

So,

$\dfrac{f_1-f_2}{f_1'-f_2'}=\dfrac{\sqrt {T}}{\sqrt{T'}}\\\\f_1'-f_2'=(f_1-f_2)\times \dfrac{\sqrt{T'}}{\sqrt{T}}\\\\f_1'-f_2'=4\times \dfrac{\sqrt{35}}{\sqrt{5}}\\\\f_1'-f_2'=10.58$

So, the number of beats is 10.58 in 35°C.

The current supplied by a battery in a portable device is typically about 0.151 A. Find the number of electrons passing through

butalik [34]

Answer:

n = 1.7*10²² electrons.

Explanation:

As the current, by definition, is the rate of change of charge, assuming that the current was flowing at a steady rate of .151 A during the 5 hours, we can find the total charge that passed perpendicular to the cross-section of the circuit, as follows:

$I =\frac{\Delta q}{\Delta t} \\ \\ \Delta q = I* \Delta t \\ \\ \Delta t = 5hs*\frac{3600s}{1h} = 18000 s$

⇒ Δq = I * Δt = 0.151 A * 18000 s = 2718 C

As this charge is carried by electrons, we can express this value as the product of the elementary charge e (charge of a single electron) times the number of electrons flowing during that time, as follows:

Δq = n*e
