Solution -
Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.
While moving from a high energy orbital to a low energy level orbital, an electron releases some energy. Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy
Hence, the given option is B
Answer:
Explanation:
Choose all the answers that apply.
Water:
1.Can dissolve most substances
2. Has a strong attraction to itself
3.Is neither acidic and basic

The correct answer is A. Experimental group
Explanation:
In experiments, the experimental group refers to the group of subjects that receives special treatment or in which the scientist or researcher intervenes. This is the opposite of a control group that does not receive treatment and therefore, it is used as a reference to measure the effect of the treatment.
This implies, in the experiment presented Group A is the control group as they do not have special treatment because they sleep normally and Group B is the experimental group as the researcher modifies their sleep time and reduces it two hours which means in this group there is a treatment or intervention.
One US penny has a thickness of about 1.52 mm.
1.52 * 1000 = 1520 mm
1520 / 10 = 152 cm
1000 pennies is about 152 centimeters tall.<span />
