Carbon dioxide is one of the main green house gases that helps in the absorbing heat from the atmosphere. It makes the temperature suitable for the organism to live on earth.
Carbon dioxide is a waste product of cellular respiration which is released inside the body an is expelled into the outer atmosphere.
Scalar and Vector quantities are Distance and Displacement respectively.
Scalar Quantity is any quantity which has only magnitude but no direction.
It is as follows:
- Distance
- Speed
- Time
- Energy
- Density
- Volume
- Temperature
- Distance
- Work
- Mass
- Frequency
- Direct current
- Entropy
- Refractive index
- Charge
- Electric potential
- Luminous intensity
- Amount of substance
- Pressure
- Power
Vector Quantity is any quantity which has magnitude as well as direction.
It is as follows:
- Displacement
- Force
- Acceleration
- Weight
- Angular Momentum
- Light velocity
- Current
- Gravitational field
- Electric field
- Linear momentum
- Torque
- Polarization
- Centripetal force
- Tension
- Thrust
- Angle
- Drag force
- Impulse
- Alternating current
- Frictional force
