Physics
1 answer:
Vlada [557]3 years ago
8 0

Answer:

y = 4 Sin (2πt)

Explanation:

Amplitude, A = 4

frequency, f = 1

Wave function is given by

y = A sinωt

where, ω is angular frequency

ω = 2 π f = 2 π x 1 = 2π

So, the desired wave function

y = 4 Sin (2πt)

4. A steel cable spanning a river is 220.000 m long when the temperature is 30.°C.
romanna [79]

Answer:

219.9208  m

Explanation:

The new length is given by

New length= Original length *(1-Temperature change*coefficient of

thermal expansion of steel)

Here, the change in temperature is 30^{\circ}-0^{\circ}= 30^{\circ}

New length= 220.000(1-30*12x10^{-6}=219.9208m

Therefore, the new length will be 219.9208 m

PLEASE HELP ME Color corresponds to the ______________ of light waves. wave speed cycles wavelength
lorasvet [3.4K]
Wavelength. Each wavelength is a certain color. For instance, shorter wavelengths (like 470nm) will be blue or violet, while longer wavelengths (like 650nm) will be red. Hope this helps! :)

Which of the following is not a component of a normal experiment?
MaRussiya [10]

Answer:

D. Validity group

Explanation:

A validity group is not necessarily a component of a normal experiment.

A normal experiment is made up of the dependent variables, independent variables, and most times the control group.

  • The dependent variable is one that relies on the outcome of the effect produced from the experimental design
  • The independent variable is the one that causes a desired effect under the study.
  • The control group is a group that does not receive any treatment nor attenuation of the conditions.
