Answer:
2.5 m/s
Explanation:
Given that :
Distance between free-throw line and basket = 5m
Time it takes basketball to reach basket = 2 seconds
Speed of the ball:
Speed = Distance / Time
Speed = 5 meters / 2 seconds
Speed = 2.5 m/s
When an atom shares electrons they form a covalent bond.
Answer:
Strong broad peak around 3200-3600 cm-1 should be present
Strong peak around around 1700 cm-1 should be absent
Explanation:
Infrared spectroscopy is an analytical technique which is used for molecular structure characterization by identifying the functional groups present in a given molecule based on the absorption wavelength (or wavenumber).
In an IR spectrum the carbonyl group is associated with the C=O stretch which occurs as a strong peak around around 1700 cm-1. For alcohol the -corresponding O-H stretching frequency occurs as a strong broad peak between 3200-3600 cm-1.
Therefore, in the case of estradiol the presence a strong broad peak in the 3200-3600 cm-1 and the absence of the peak at around 1700 cm-1. would suggest that the transformation is complete.

The energy of a nuclear reactor gets converted to electricity by using steam. As steam converts mechanical energy to electricity.
Answer: Option C
<u>Explanation:
</u>
Nuclear reaction works on the principle of nuclear fission. The main functioning of nuclear reactor is the generation of neutrons by fission of Uranium oxide.
The rate of generation of neutrons need to be controlled in the reaction to have a controlled chain reaction which is suitable for generating electricity.
So, the controlling of rate of nuclear generation is done by moderators. The moderators are generally water or graphite in any nuclear reactor. So during these process, steam is produced in the reactor core which then flows through a turbine engine.
The steam rotates the turbines in the generator and thus the mechanical energy of the turbine during rotation is converted as the electrical energy in the generator.
