Answer:
0.091 sec
Explanation:
f = frequency of oscillation of the mass attached to the spring = 11 Hz
T = Time period of oscillation of the mass attached to the spring = ?
Time period and frequency of oscillation of the mass attached to the end of spring are related as
Inserting the values
T = 0.091 sec
Explanation:
the no of proton of an element is found in the inner part of the orbital of an element along with the neutron ,also knowing that this two add up to give mass no an element
where neutron+proton=mass no=nucleon no,where proton= electron, unless it carries charges call ion
The speed of a periodic wave disturbance is 2.45 m/s.
<u>Explanation:</u>
Sound waves travel as sinusoidal nature. And the distance between the two successive crests or troughs are determined as the wavelength of the sound wave.
Similarly, the measure of number of complete cycles in a given time is defined as frequency of sound wave. The speed of any wave is determined as the product of wavelength of transmission of wave and frequency of that wave.
Thus,
×
So,
× = 2.45 m/s.
Thus, the speed of periodic wave disturbance is 2.45 m/s.
Answer:
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
Explanation:
The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
<h3>Wavelength of the light</h3>
The wavelength of the light is determined using the following formulas;
where;
- λ is wavelength
- d is width of the slit
- D is the distance of the screen
- y is distance between the central bright fringe and dark fringe
<h3>Actions that would decrease the width of the central bright</h3>
y = (λD) / (d)
- Decrease in the wavelength of the light
- Increase in the width of the slit
Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
