To get it to start moving, he have to exert a force equal to its maximum force of static friction.
F= fs,max = Ms m g= (0.21) * (180) * (9.8) = 370 N
Let me know if im wrong but if not brainliest user for helping or best answer
Answer:. 1008
7×9= 63 square meters total area.
Each square meter is 100 cm wide and 100 cm long. 100÷25 = 4, so it will take 4 tiles wide and 4 tiles long for each square meter. 4×4= 16
Multiply 16 × 63 = 1008 tiles needed.
Explanation:
While measuring , there are a lot of errors which can happen due to which ""true distances"" be different for different groups even though they are measuring the same distance.
While measuring , there are a lot of errors which can happen , to find the most correct value in order to make the result precise and accurate number of measurements needed to be done in order to reduce the error
As nothing can be measured with full precision and accuracy, different measurements for different groups even though they are measuring the same distance.

Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform, ![f=10\ kHz=10^4\ Hz](https://tex.z-dn.net/?f=f%3D10%5C%20kHz%3D10%5E4%5C%20Hz)
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :
![f=\dfrac{n}{t}](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7Bn%7D%7Bt%7D)
![n=f\times t](https://tex.z-dn.net/?f=n%3Df%5Ctimes%20t)
![n=10^4\ Hz\times 100\times 10^{-3}\ s](https://tex.z-dn.net/?f=n%3D10%5E4%5C%20Hz%5Ctimes%20100%5Ctimes%2010%5E%7B-3%7D%5C%20s)
n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.
It’s C for sure I took this awhile back but I still remember... so thermal equilibrium is when to object have the same temperature due to them touching and transferring temperature for example if we have two metal blocks and one them is hotter than the other when you put them together the heat transfers and makes them both the same temperature.
