Venus & Mars are the 2 planetss
Answer:
In the parallel plate capacitor,
q = e0EA, q is the charge on the plate, E is electric field intensity, A is the area of each plate, e0 = 8.854 x 10^-12F/m.
The charge density is q/A(charge per unit area)
q/A = e0 x E, from the equation above.
Therefore, q/A = 1.40 x 10^4V/m x 8.854 x 10^-12F/m
q/A = 12.3956 x 10^-8 = 1.23956 x 10^-7C/m2
Explanation:
A parallel plate capacitor consist of two plates facing eachother with separation d in between them. One of the plate is positively charged and the other is negatively charged. There is a dielectric material in between the plates. The charges on the plate is given as: q = e0EA
<u>Answer:</u> The molarity of solution is 0.954 M
<u>Explanation:</u>
We are given:
5.098 mass % solution of potassium hydroxide
This means that 5.098 grams of potassium hydroxide is present in 100 grams of solution
To calculate volume of a substance, we use the equation:
Density of solution = 1.05 g/mL
Mass of solution = 100 g
Putting values in above equation, we get:
To calculate the molarity of solution, we use the equation:
Given mass of potassium hydroxide = 5.098 g
Molar mass of potassium hydroxide = 56.1 g/mol
Volume of solution = 95.24 mL
Putting values in above equation, we get:
Hence, the molarity of solution is 0.954 M
Answer:
1. alpha - decreased mass by 4 - decrease atomic number by 2
2. beta electron - no change - increase by 1
3 - beta positron - no change - decrease by 1
4. gamma - no change - no change
5. electron capture - no change - decrease by 1
Explanation:
There are five main types of radioactive decay, a process where the nucleus loses energy by emitting radiation, these radiation or type of radioactive decay are alpha particles, beta particles, positron or beta positron, gamma particles and electron capture.
The effect of these particles causes a change in the number of subatomic which leads to different atomic mass and atomic numbers after the decay -
1. alpha - decreased mass by 4 - decrease the atomic number by 2
2. beta electron - no change - increase by 1
3 - beta positron - no change - decrease by 1
4. gamma - no change - no change
5. electron capture - no change - decrease by 1
The distance between molecules INCREASES when the substance vaporizes
Explanation:
The distance between the molecules increase due to the fact that as you put more energy into the substance the kinetic energy of the molecules increases. This means they are vibrating more vigorously and the collision between the molecules are becoming more energetic. This means the collisions fling the molecules far away from each other (due to their increased momentum) hence the increased average distance between molecules.
