Answer:
If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves.
Explanation:
0.25 m/s squared

The wavelength is equal to Planck's constant divided by the ball's momentum.
This means that:
lambda = h / p .............> equation I
Momentum = mass * velocity ............> equation II
Substitute by equation II in equation I, you get:
lambda = h / mv
Now, we are given:
lambda = 8.92 * 10^-34 m
Planck's constant = 6.625 * 10^-34
velocity = 40 m/sec
Substitute with these givens in the above equation to calculate the mass as follows:
8.92*10^-34 = (6.625*10^-34) / (40*m)
mass = 0.0185678 kg
Sulphur
The missing element is sulphur
Here the compound is composed of element X and chlorine.
it is given,
XCl (6) ----> 6Cl
mass = 13.1%
it is X and Cl = 100%-13.10%
= 86.90%
chlorine = 86.90
X = 13.10
We assume 100g of sample
so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.
now we split that chlorine into two moles of chlorine.
- Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
- We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
- we discover that we have 0.4086 moles of X when we divide this by six.
- We obtain those moles of X from 13.10 g of X.
- Given that Mueller masses grams per mole, I can compute the molar mass.
- 13.10 grams of X are contained in 0.4086 moles of X.
- Or, to put it another way, each remote has a molar mass of 32–06 grams.
- The element with this molar mass is sulfur, as I can see from the periodic table.
- Okay, so the element we're looking for in this situation is sulfur.
