Answer:
The constant angular acceleration of the wheel is 12.16 rad/s²
Explanation:
Given;
initial angular distance, θ = 28
time of the motion, t = 5 s
initial angular velocity is calculated as;

final angular velocity is given as, 
The constant angular acceleration is calculated as;

Therefore, the constant angular acceleration of the wheel is 12.16 rad/s²
Answer:
About 2 units.
Explanation:
We assume that there is no heat dissipating instrument in the room
Total cooling load of the room is defined from the given below equation
=
+
+
where
= 10*100 W =1 KW
= 40*360 KJ/h= 4 KW
=15000KJ/h= 4.17 KW
= 1+4+4.17=9.17 KW
the number of air conditioner unit is =
=1.83
which is approximately 2 units
Answer:
<em>Physical activities play an important role in manage our stress levels</em>.
<u>Explanation:
</u>
In our daily life <em>we face many stressful experiences such as job, studies, a chronic disease </em>etc., <em>the brain send warnings to the muscles and to the adrenal glands which releases adrenaline and cortisol</em>. <em>Stress leads to high blood pleasure and there are many strategies to manage our stress,</em> keeping our mind in a positive attitude helps to reduce stress levels.<em> Doing physical activities keep our mind away from stress. Yoga, Meditation, Deep breathing exercises, Aerobics keeps our mind free from stress.</em>
Explanation:
By one dimension, one means motion along a line, or in one particular direction. Think of a car going down a straight road, or a person running on a straight track.
...
1. Motion in one dimension
2. Average velocity.
3. Instantaneous velocity.
Spectroscopy is the study of the absorption and emission of light and other radiation by matter.
<h3>How can we conclude the statement?</h3>
Spectroscopy is the interaction of lights and atoms and the study of the emission and absorption of light.
Spectroscopy can be defined as the study of light absorption as well as its emission. It is also uses to study of structure of atoms.
It offers techniques that has to do with how a sample responds to the radiation of light.
Its applications are:
- Used to determine atomic structure To determine metabolic functions
- studies spectral emissions
- Helps to improve the effectiveness of drugs
