The relative density of the battery decreases when the battery is turned from charging to discharging position.
The relative density of the charged battery is mostly 1.28 to 1.3 and the relative density of the discharged battery is 1.15.
Thus, option C is more appropriate for the given case.
Answer:
Explanation:
Given
Potential Energy of a particle is given by
For minimum or maximum Potential Energy differentiate U(x) w.r.t x
putting
To know minimum value check
at x=-2
so at x=-2 potential energy is minimum
Explanation:
Her cells will not work well when they have low levels of oxygen.
Answer:
The unit rate is $0.22 lb
Explanation:
The given parameters are;
The price for 18 lb = $3.99
We have;
The unit rate is the price for one unit. Whereby the unit of measurement is the lb, we have that one unit = 1 lb.
Therefore, given that 1 lb = 18 lb/18, the price of 1 lb which is the unit rate is given as follows;
18 lb price = $3.99
Divide both sides by 18 to get;
18 lb/18 = $3.99/18 = $0.221
Therefore, we have;
1 lb = 18 lb/18 = $0.221
The unit rate, which is the cost for 1 lb to the nearest hundredth = $0.22/lb.

Explanation:
1. Sound energy is the wave form of mechanical energy that is transferred by the vibration of the of the medium through which it propagates
2. An electrical conductor is used to conduct electricity from one point to another
3. An object or material flows when it has a smooth motion towards a given direction, such as a river
4. Thermal ener<u>g</u>y is the form of energy that is given off by a body as sensible heat that can be measured as a temperature by a thermometer
5. Electric current is the electricity in a circuit
6. An insulator is a material that limits the flow of electricity or heat
7. Light energy is the form electromagnetic energy which the eye can sense
8. An electric current flows an electric circuit which consist of a source of electricity and an path through which the electric current can easily flow.
