Answer:

Explanation:
When the springs are connected end to end, it means they are connected in series. When the springs are connected in series, the stress applied to the system gets applied to each of the springs without any change in magnitude while the strain of the system is the sum total of strains of each spring. The spring constant of the resultant system is given as,

Here, n = 10
Spring constant of each spring = k
Thus,




Explanation:
Hey there!
Given;
Force (f) = 100 N
Acceleration (a) = 10m/s^2.
Mass (m)=?
We have;
Force = mass * acceleration.
So,
100 = m * 10
Or, 100 = 10m
Or, m= 100/10
Therefore, mass is 10kg.

Chemical properties due to the changes in both
as per the reaction we have

so here 1 mole of H2 react with 1 mole of O2 and give 1 mole of H2O2 as the product
now we will find the moles of given reactant
moles of H2

moles of O2

so here both present in 1 mole each hence the product will also formed 1 mole
so here we have
H2O2 will form
so mass of the product
mass = moles* molecular mass


so the product mass will be 34 g
The phrase below that is able to be compressed is D. gas only.
Although it is possible to compress liquids, it requires a great deal of pressure to accomplish a little compression, which is why liquids and solids are often referred to as incompressible.
