Glucose has a chemical formula of: C6H12O6 That means glucose is made of 6 carbon atoms, 12 hydrogen atoms and
(6 oxygen atoms)
ANSWER B: A location can only have one elevation.
Answer and Explanation:
Data provided as per the question is as follows
Speed at point A = 20 m/s
Acceleration at point C = 
The calculation of the magnitude of the acceleration at A is shown below:-
Centripetal acceleration is
now we will put the values into the above formula
= 
After solving the above equation we will get
Tangential acceleration is
Three different units of energy is
1. Joule: is is SI unit of measuring thermal energy or heat
2. Calorie: this system of energy is used when we take CGS system of mass and specific heat capacity
3. BTU: this system is known as british thermal unit which is used in measuring engineering calculations
Answer:
All are true except the last point that says that a battery is a current source and the current at the outlet is always the same.
Explanation:
- A battery is an electro-chemical device which converts the chemical energy into usable electrical energy thus it provides electrical energy.
- Since, the battery maintains a a constant potential difference between its terminals, once connected.
- Since, the movement of electric current requires energy, which is supplied by the electric potential energy stored in the battery.
- The current in the battery flows as per the Ohm's law and we can not say that the current leaving will always remain constant.
- As the current is the flow of electric charge, and charges are not stored in batteries unlike capacitors, thus the current at the leaving end will depend on Ohm's law and will vary accordingly.
