Answer:
0.3376 mm
Explanation:
The computation of the spacing in mm between the slits is shown below:
As we know that
where,
= wavelength
L = distance from the scrren
= spanning distance
As there are 11 bright fingers seen so m would be
= 11 - 1
= 10
Now placing these values to the above formula
So, the spacing is
= 0.3376 mm
We simply applied the above formula.
The amplitude and wavelength are measured in meters while frequency is measured in decibels.

Units of measurement:</h2>
- Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.
- Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.
- Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.
- Wave speed: It is measured in m/s.
- Loudness: The loudness of the sound is measured in decibels.
Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

So, the weight is supported by the tension in the two wires, but only part of the tension goes in holding the body: the vertical component.
If the angle between the ceiling and the wire is 40 deg, then the vertical component is
T_y = T * sin(40),
There are two wires, so together they do
2*T*sin(40)
And all this holds the weight of the body, so:
2*T*sin(40)=150 ----> T = 75/sin(40)~116.68 N,
Notice how it is larger than 150N (both wires is ~ 233 N), as the angle becomes smaller, there is less tension that is vertical, so one needs more tension to make the vertical component as large as (half) the weight of the body
Hope it helps!
Answer:
Solar cell generates DC
Windmill generates AC
Explanation:
Solar cell generates DC from the panel, to use this DC for electricity it has to be passed to an inverter which convert DC to AC.
Windmill generates AC from the wind blades. This type of energy can be used directly with household appliances using AC, or passed to a rectifier to convert it to DC.
Well I can’t bee any so the closest one is 6 but the answer should be 6.1 and also I’m a middle schooler so I want to learn more stuff like this but I recommend 4.5
