An increase in the temperature will speed up the reaction by increasing the frequency and efficiency of the collisions of molecules.

Rearrange the equation for the area of a rectangle (A=l x w) to solve for length, L
Mariana [72]
Not sure if this is what you mean but l= A/w
(length equals area divided by width)

STP is the abbreviation of standard condition for temperature and pressure which is 273.15K temperature and 1.013× 10^5 Pa pressure. Since the pressure and temperature changes, I assume the question would ask about the result of the volume. The temperature used in ideal gas should be Kelvin, so 27 Celcius would be 300.15K.
The calculation would be
PV=T
V=T/P

V2/V1= T2*P1/T1*P2
V2/V1=273.15K*  90^10^3Pa/ 300.15K *  1.013× 10^5 Pa
V2= 0.81904 * 51.7ml
V2= 42.34ml

The force of 75 N must overcome in order to get the truck to start moving. What type of friction must be overcome?
Tamiku [17]

Answer:

Static Friction.

Explanation:

Friction is the force that resists the relative motion between the surfaces sliding against each other.

Static friction is friction between objects that are not in relative motion with each other.

The coefficient of static friction, typically denoted as  μs,

Static friction arises due to surface roughness( relative term)

The static friction force can be overcome by an applied  maximum force

F max =  μs x N

N= normal force

Any force smaller than F max attempting to slide one surface over the other is opposed by a frictional force of equal magnitude and opposite direction.

Any force larger than F max overcomes the force of static friction and causes sliding to occur.

This maximum force is sometimes called the limiting value also. Here that value is 75 N.
