Investigative questions for heating curve of water in an experiment and hypothesis investigative question ​

Physics

SIZIF [17.4K]3 years ago
4 0

Given what we know, we can confirm that investigative questions are used to develop and test hypotheses and often lead to the formation of an experiment.

<h3>What are investigative questions?</h3>

These are questions posed by scientists that will often lead to a hypothesis. They are the crucial first step in the scientific process. Some examples of investigative questions include:

  • Why are plants green?
  • Does gravity affect all objects equally?
  • What makes ice melt?

etc.

Therefore, we can confirm that investigative questions such as these are often the basis on which hypotheses are created and experiments are made in order to test the speculated results.

A grasshopper floating in water generates waves at a rate of three per second with a wavelength of two centimeters. (a) What is
Nastasia [14]

Answer:

(a) 0.33 second

(b) 6 cm/s

Explanation:

Frequency, f = 3 waves per second

wavelength, λ = 2 cm = 0.02 m

(a) The period of wave is defined as the time taken by the wave to complete one oscillation. It is the reciprocal of frequency.

T = 1 / f = 1 / 3 = 0.33 second

(b) the relation between wave velocity, frequency and wavelength is given by

v = f x λ

v = 3 x 0.02 = 0.06 m /s

v = 6 cm /s

A radio have a wavelength of 0.3m and travels at a speed of 300,000,000 m/s. What is the frequency of this wave?​
Ilya [14]

The frequency of the wave is 1\cdot 10^9 Hz

Explanation:

The frequency, the wavelength and the speed of a wave are related by the following equation:

c=f \lambda

where

c is the speed of the wave

f is the frequency

\lambda is the wavelength

For the radio wave in this problem,

\lambda = 0.3 m

c=300,000,000 m/s = 3\cdot 10^8 m/s

Therefore, the frequency is:

f=\frac{c}{\lambda}=\frac{3\cdot 10^8}{0.3}=1\cdot 10^9 Hz
