Who conducted the study?

Explanation:

One good question to ask the toothpaste making company is who conducted the study?

A company making toothpaste claiming a scientific study revealed that their toothpaste makes the mouth five times cleaner must have introduced a bias in this finding.

For a scientific study to be accepted and substantiated, it must have been tested and repeated by other scientists.
If no other scientist confirms this, then there is an obvious bias in the claim and it is not scientific.

Vlada [557]

here's the solution,

we know that,

=》

$wave \: speed = wavelength \times frequency$

so,

=》

$18 = 3 \times f$

=》

$f = \dfrac{18}{3}$

=》

$f = 6$

frequency = 6 hertz

mihalych1998 [28]

Answer:

Average speed = 1.3 m/s

Explanation:

Given that a student walks 160 m in 150 s. The student stops for 30 s and then walka 210 m farther in 140 s.

Neglect the time the student stops.

The total distance covered will be

Distance = 160 + 210

Distance = 370 m

The total time of the whole distance journey will be

Time = 150 + 140 = 290 s

The formula for speed is

Speed = distance/time

Speed = 370/290

Speed = 1.276 m/s

Therefore, the average speed is 1.3 m/s approximately
