Answer:
Explanation:
Gauss' Law should be applied to find the E-field 3.9 cm from the surface of the sphere.
In order to apply Gauss' Law, an imaginary spherical shell (Gaussian surface) should be placed around the original sphere. The exact position of the shell must be 3.9 cm from the surface of the original sphere.
Gauss' Law states that
Here, the integral in the left-hand side is equal to the area of the imaginary surface. After all, the reason behind choosing the imaginary surface a spherical shell is to avoid this integral. The enclosed charge in the right-hand side is equal to the charge of the sphere, -84.0 nC. The radius of the imaginary surface must be 5 + 3.9 = 8.9 cm.
So,
It is made up of B) atoms
Each jump covers one center of the square to the other. If you can imagine the scenario, a single jump would cover a length of the side of one whole square. So, if it took three jumps, the total distance would be
d = 3 * 5 cm
d = 15 cm
Therefore, the magnitude or distance is 15 cm. The displacement depends on the direction of motion.
Answer:
The advantages of these types of thermometers is that they are cheap, easy to read, can be submerged in liquids, require very little maintenance and are reliable. The disadvantages are that they break easily and there is risk of mercury poisoning if the glass tube breaks.
