Answer: 12.6 newtons

Explanation:

Take the equation, static force equals static friction times normal force.             ( F = μn )

Divide both sides by static friction so normal force is the answer.

( F / μ = n )

Insert your numbers (4.11 F and 0.325 μ) into the equation to get your answer.

( 4.11 / 0.325 = n )

n = 12.6

My first time helping someone and future people on this site. This is the answer I put in and got right.

Answer:

Genetics is a branch of biology that studies the inheritance of physical and behavioural characteristics of living things, and how these traits are passed down through generations. Geneticists study genes and the science of heredity (inherited traits passed down through generations).

When a gas is rapidly compressed (say, by pushing down a piston) its temperature increases. When a gas expands against a piston,
shusha [124]

Answer:

Explained in explanation

Explanation:

The first law of thermodynamics states that the change in internal energy of a system(ΔU) is equal to the sum of the net heat transfer into the system(Q) and the net work done on the system(W). In equation, this law is;

ΔU = Q + W

Now, when there's gas inside a container with a movable piston that's tightly fitting, we will assume that the piston can move up and down thereby compressing the gas or allowing the gas to expand against it.

Now these gas molecules inside the container possess kinetic energy. Thus, the internal energy(U) of the system is simply the sum of all the kinetic energies of the individual gas molecules present in the container.

Therefore, if the temperature(T) of the gas increases, then the speed and internal energy(U) of the gas molecules will also increase. In the same way, if the temperature of the gas decreases, the speed and internal energy of the gas molecules would also decrease.

Now, back to the question, when the piston is pushed down, it does work on the gas and the gas does negative work on the piston. Thus, the gas will be get compressed to a smaller space, and thereby making the gas molecules to hit the piston at a faster rate. Thus, there is a decrease in speed and as we saw earlier that when there is a decrease in speed, it means temperature has decreased.

Whereas, when the piston is moved up, the gas does positive work on the piston and the speed of the gas molecules will increase. Like I said earlier that increase in speed means increase in temperature.
