1. Inside a circle described by a point charge at its center will not be uniform field as a point charge field will change with distance where as we move away the field strength will go down.
2. between parallel plates of equal charge and equal magnitude will have zero electric field because both plates are of same charge so electric field of both plates will cancel each other.
3. inside a circle described by identical, evenly-spaced point charges around the circumference field will be zero as all charges are distributed uniformly and they cancel the field effect of each other.
4. between parallel plates of equal charge and opposite magnitude field will be nearly uniform as the two charges are opposite in nature and equal in magnitude so the effect will be added.
So answer of the above will be between parallel plates of equal charge and opposite magnitude
Answers and Explanation:
Forms of Kinetic energy
- Translational kinetic energy
- Rotational kinetic energy
- Vibrational kinetic energy
Forms of Potential energy
- Gravitational potential energy
- Electrostatic potential energy
- chemical potential energy
Energy efficiency is a measure of the amount of energy conserved in a process. It is the ratio of the output energy to the input energy.
Differences between renewable and non renewable energy
- Renewable energy can replenish themselves by recycling and replacement while non-renewable energy cannot
- Renewable energy are continuously available while non renewable energy are exhausted
- Renewable energy has low carbon emission and hence environment friendly while non renewable energy has high carbon emission and not environmental friendly
Sources of renewable energy
Solar energy.
Wind energy.
Hydro energy.
Tidal energy.
Geothermal energy.
Biomass energy.
Sources of non-renewable energy
Coal
Petroleum
Natural gas
Distribution of energy consumption in the US by energy sector
Petroleum = 36.2 %
Natural gas = 28%
Coal = 13.9%
Renewable energy = 11.0%
Nuclear electric power = 8.4%
Most of the energy consumed by the United States is non-renewable
Electricity is a secondary source of energy. It is derived from the conversion of primary sources
A secondary source of energy is a derivative from the transformation of primary sources of energy
Answer:
Explanation:
y = Distance from the center point
d = Separation between slits = 0.3 mm
D = Distance between slit and screen = 1.5 m
= Wavelength = 700 nm
m = Order = 1
We have the relation
The distance from the screen at which the first bright fringe beyond the center fringe appear is .
You used density, because water/ice has a density of 1, and ice will sink in anything with a lesser density
