Answer:
The pressure of the tire will be 4.19 atm
Explanation:
The ideal gas equation is:
p0 * V0 / T0 = p1 * V1 / T1
Since V0 = V1 because the volume of the tire doesn't change
p0 / T0 = p1 / T1
p1 = p0 * T1 / T0
We need absolute temperatures for this equation
16 C = 289 K
45 C = 318 K
Now we replace the values:
p1 = 3.71 * 318 / 289 = 4.19 atm
<span>Permanent magnets are objects made from magnetized material and produce continual magnetic fields. Everyday examples include refrigerator magnets used to hold notes on a refrigerator door.</span><span>Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic. Examples of these materials include iron, nickel, and cobalt.</span><span>The counterexample to a permanent magnet is an electromagnet, which only becomes magnetized when an electric current flows through it.</span>Magnets always have a north pole and a south pole, so if one were to split a permanent magnet in half, two smaller magnets would be created, each with a north pole and south pole.Permanent magnets are made from ferromagnetic materials that are exposed to a strong external magnetic field and heated to align their internal microcrystalline structure, making them very hard to demagnetize.
We will use Newton's second law to find the resultant force:
F = ma
For this, we need the acceleration given by:
a = (v - u) / t
a = (85 - 35) / 20
a = 2.5 m/s²
F = 148 x 2.5
F = 370 Newtons
