Answer:
The force constant of the spring is 735 N/m.
Explanation:
It is given that,
Mass of fruit, m = 1500 g = 1.5 kg
Compression in the scale, x = 0.02 m
We need to find the force constant of the spring on the scale. The force acting on the scale is given by using Hooke's law. So,
![F=-kx](https://tex.z-dn.net/?f=F%3D-kx)
Also, F = mg
![mg=kx](https://tex.z-dn.net/?f=mg%3Dkx)
k is force constant
![k=\dfrac{mg}{x}\\\\k=\dfrac{1.5\times 9.8}{0.02}\\\\k=735\ N/m](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7Bmg%7D%7Bx%7D%5C%5C%5C%5Ck%3D%5Cdfrac%7B1.5%5Ctimes%209.8%7D%7B0.02%7D%5C%5C%5C%5Ck%3D735%5C%20N%2Fm)
So, the force constant of the spring is 735 N/m.
When the object is at the focal point the angular magnification is 2.94.
Angular magnification:
The ratio of the angle subtended at the eye by the image formed by an optical instrument to that subtended at the eye by the object when not viewed through the instrument.
Here we have to find the angular magnification when the object is at the focal point.
Focal length = 6.00 cm
Formula to calculate angular magnification:
Angular magnification = 25/f
= 25/ 8.5
= 2.94
Therefore the angular magnification of this thin lens is 2.94

Duracell batteries are an example of an electrochemical cell that is powered between the reaction of Magnesium and Zinc, occurring in basic conditions (alkaline battery). This type of reaction has a precise output of 1.5 volts, and looks like this:
Zn + 2MnO2 ➡️ ZnO + Mn2O3
It’s not rechargeable.
Golf Cart Batteries are an example of an electrochemical cell that is powered by the reaction between Lead and Sulfuric Acid (Lead-Acid battery). This type of reaction occurs on larger scales than an alkaline battery, and thus can generate a variety of powers depending on how many instruments are present within the battery. The reaction looks like this:
PbO2 + Pb + 2H2SO4 ➡️ 2PbSO4 + H2O
This is a rechargeable cell, but is rather prone to discharging by the environment and surroundings of the battery.
Answer:
Explanation:
the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats, and the inverse of the spatial frequency.
Wavelength measures the distance from one point of a wave to the same point on an adjacent wave, whereas the frequency represents how many waves are produced from the source per second. Wavelengths are measured in nanometers and frequencies are measured in hertz or waves per second
