Which of the following had have the highest viscosity ?
B) corn syrup bevause corn syrup is a mixture of 2 elements
Answer:
Sample Response: In a vacuum, there are no atoms or particles that interfere with the path of light. However, in other media, the speed of light is lower than 3.0 × 108 m/s because the wave is continuously absorbed and re-emitted by each atom in its path. The differences in speed are due to the composition of the medium and the density of the particles in the medium.
Explanation:
Franklin had been waiting for an opportunity like this. He wanted to demonstrate the electrical nature of lightning, and to do so, he needed a thunderstorm.
He had his materials at the ready: a simple kite made with a large silk handkerchief, a hemp string, and a silk string. He also had a house key, a Leyden jar (a device that could store an electrical charge for later use), and a sharp length of wire. His son William assisted him.
Franklin had originally planned to conduct the experiment atop a Philadelphia church spire, according to his contemporary, British scientist Joseph Priestley (who, incidentally, is credited with discovering oxygen), but he changed his plans when he realized he could achieve the same goal by using a kite.
<u>Answer</u>
C.39.2 kPa
<u>Explanation</u>
The pressure in liquids depend on the depth or what we call the liquid column(h), the density of the liquid(σ) and the the acceleration due to gravity(g).
h = 4.00 m
σ = 1000 Kg/m³
g = 9.8m/s²
Pressure Is given by;
P = σgh
= 1000 × 9.8 × 4
= 39200 Pa
=39.2 KPa
Answer:
Displacement.
Explanation:
The change in between the starting position (initial position) and your final position is the amount of distance you <em>actually </em>traveled.
For example, you can use a triangle. The distance you travel for side length a & b is equal to the distance you travel on side c (the hypotenuse). You are pretty much solving for the hypotenuse in this case, or the displacement.
