The smallest unit among the options is mm(Millimeters). Thus, option a) is the answer.
The smallest unit among the options is "a) mm," which stands for millimeter. It's a metric unit of length that is one-thousandth of a meter (1/1000). Millimeters are commonly used for precise measurements, especially in fields like engineering, science, and manufacturing, where accuracy is crucial.
Centimeters (cm) are larger than millimeters, with one centimeter being equal to 10 millimeters. Meters (m) are even larger, being the base unit of length in the metric system. Kilometers (km) are the largest unit among the options, equivalent to 1000 meters.
In summary, when comparing the given options, millimeters are the smallest unit of length, followed by centimeters, meters, and then kilometers, with each subsequent unit being larger by factors of 10.
The correct option is : a) mm.

Answer:
The the smallest unit among the options provided is mm (millimetre).
Explanation:
mm (millimetre) is a metric unit of length equal to one-thousandth (1/1000) of a metre.
cm (centimetre) is equal to one-hundredth(1/100) of a metre. It is a subunit of length is the SI Sytem. It is used to measure small lengths.
m (metre) is the distance that light travels in vaccum in 1/299792458 seconds. It is the fundamental building block in metric system and is universally accepted.
km (kilometre) is equal to 1000 metres. It is commonly used to measure longer distances.

The right answer is the activation energy.
The catalyst increases the reaction rate by introducing new reaction paths (mechanism), and lowering its activation energy, or activation Gibbs free energy. By doing this it can increase the speed, or lower the temperature of the reaction. It is important to note that the catalyst does not alter the total Gibbs free energy of the reaction which is a system state function and therefore has no effect on the equilibrium constant.
Answer : The correct option is, the activation energy
Explanation :
Activation energy : Activation energy is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy.
During the chemical reaction, the reactants react to form product. When a catalyst is added to a chemical reaction then the reaction becomes faster that means the rate of reaction increases and the activation energy decreases.
In the given diagram, 'G' is the activation energy without catalyst and 'H' is the activation energy with catalyst.
The energy diagram is shown below.
Answer:
Hypertonic solution
Explanation:
A solution with higher solute concentration is called as hypertonic solution while the one with less solute concentration is termed as hypotonic solution. Osmotic movement of water occurs from hypotonic to hypertonic solution to balance the concentration of solution. When an animal cell is placed in a hypertonic solution, it loses water through osmosis and shrinks.
Answer: c. high-level waste
Explanation:
The used or spent fuel comes from the nuclear reactor that can be no longer efficient to be used again for the purpose of generating electricity, because the efficiency to conduct fission reaction by such fuel is low. But still it may be thermally hot, highly radioactive and harmful. It comes under the category of high level wastes. The high level wastes are those wastes that are produced as a byproduct of the nuclear reactors.
