Answer:
The displacement of the car is 10 km at an angle of 36.9 degrees.
Explanation:
(AP) A car travels 8.00 km west from A to B; then the car travels 6.0 km north from B to C. Calculate the total displacement of the car? to. 10 km 36.9 ° b. 10 km 34.8 ° c. 12 km 34.8 ° d. 12 km 34.8 ° e. 12 km 35.9 °
It is given that,
A car travels 8.00 km west from A to B
The car travels 6.0 km north from B to C
We need to find the total displacement of the car. Initially, the car is moving due west and then it moves due north. So, the displacement of the car is given by :
To find angle,
So, the displacement of the car is 10 km at an angle of 36.9 degrees.
Hi
<span>Explicit- and implicit-solvent molecular dynamics simulations are performed to study complexation in two polyelectrolyte systems: poly(styrene sulfonate)/poly(allylamine hydrochloride) (PSS/PAH) and poly(acrylic acid)/poly(allylamine hydrochloride) (PAA/PAH). Both these systems have been used in layer-by-layer assembly of polyelectrolyte films, with the first of these typically yielding linear growth in film thickness with increasing numbers of layers and the second yielding exponential growth. In both the systems, the polyelectrolytes have the same number of monomers and are present in stoichiometric proportion, and water is used as solvent. Simulations give important insights into the structure and composition of the complexes. We found that the PSS/PAH complex is more compact and has a smaller fraction of water than the PAA/PAH complex due to the presence of phenyl rings in the PSS chain and the hydrophilic nature of the charged group in the PAA chain. Either an increase in salt concentration or a decrease in partial charge fraction increases swelling and the water content in the complex. To overcome the computational limitations associated with the explicit-solvent simulation, a simple strategy to develop the force field for an implicit-solvent simulation is proposed. In the absence of salt and for fully charged polyelectrolytes, the radius-of-gyration and the various radial distribution functions predicted by the implicit-solvent simulation match well with those predicted by the explicit-solvent simulation, while reasonable agreement is obtained in the other cases. The implicit-solvent simulation was performed for bigger system sizes, and we observed trends similar to those observed for smaller system sizes, suggesting that the simulation results are independent of system size.

Answer:
It is difficult to magnetize.
Force = change in momentum / impact time
= mass (change in velocity) / impact time
= 0.07 (0.5-0) / 0.5
= 0.07N

Hey mate......
Explanation:
<em>In a class, the teacher asked a student named Mary to mark America on the Globe. Mary did it correctly, now the teacher asked the students "Who found America?" </em>
<em> The students replied.....</em>
<h2>Ma'am Mary found America! </h2>
Lol!!
Hope it helps!
