Answer:
Ex(P) = -3.602 x 10^6 N/C
Explanation:
- q2 = 2.6 μC = the net charge on the conducting shell
- inner radius of conducting shell = a = 2.2 cm =0.022m
- outer radius of conducting shell = b = 4.5 cm = 0.045m
1) To get Ex(P), the value of the x-component of the electric field at point P, located a distance 8.8 cm along the x-axis from q1 ;
Ex(P) = k(q1+q2)/r^2
= 9 x 10^9 (-5.7 + 2.6) x 10^-6 /0.088^2
Ex(P) = -27.9 x 10^3/ 0.007744
Ex(P) = -3.602 x 10^6 N/C
Answer:
Atoms are the most basic units of an element whereas molecules are atoms that are chemically bonded together.
Explanation:
- The atoms are made up of protons, neutrons, and electrons that are the basic constituents of matter.
- The atoms occur in nature as single or bonded.
- The inert gases are the atoms that they occur as the individual atoms in nature.
- All other atoms in nature are bonded to the same elements or different elements and form molecules.
- Hence, atoms are the most basic units of an element whereas molecules are atoms that are chemically bonded together.
Answer:
A. They travel faster in a solid than other mediums
Explanation:
Sound waves travel faster in solids because the density of solids is higher than that of liquids which means that the particles are closer together and sound can be transmitted more easily.
Answer:
No it can't .
Explanation:
In accordance to the law of conservation of energy
<em>≈ 0.47 m/s²</em>
<em>Hi there !</em>
<em>Acceleration formula</em>
<em>a = (v₂ - v₁)/t</em>
<em />
<em>a = (26.8m/s - 24.8m/s)/4.3s</em>
<em>= (2m/s)/4.3s</em>
<em>≈ 0.47 m/s²</em>
<em>Good luck !</em>
