- Alarm Clock. The buzzing sound of an alarm clock helps you wake up in the morning as per your schedule. The sound is something that you can’t see, but hear or experience.
- Cell Phones Cellphones have become like Oxygen gas in modern social life. Hardly, anyone would have been untouched by the effects of a cell phone. Whether conveying any urgent message or doing incessant gossips, cellphones are everywhere. But do you know how does a cell phone work? It works on the principle of electricity and the electromagnetic spectrum, undulating patterns of electricity and magnetism.
- Walking.Now, when you get ready for your office/school, whatever medium of commutation is, you certainly have to walk up to a certain distance. You can easily walk is just because of Physics. While you have a walk in a park or on a tar road, you have a good grip without slipping because of a sort of roughness or resistance between the soles of your shoes and the surface of the road.
Explanation:
physical is related to things perceived through the senses as opposed to the mind; tangible or concrete.

-12.25N
Explanation:
Given parameters:
Mass of shopping cart = 7kg
Time = 2s
initial velocity = 3.5m/s
Unknown:
Average net force required to stop the cart = ?
Solution;
According to newton's second law"acceleration of body results when a net force acts on a body".
F = ma
where F is the force
m is the mass
a is the acceleration
Acceleration is the change in velocity with time
a = 
Therefore;
F = m x
v is the final velocity, in this case it is zero, 0
u is the initial velocity
t is the time taken
Putting in the parameters:
F = 7 x 
= -12.25N
This force that will stop the cart will be directed in the opposite direction with a magnitude of 12.25N

Answer:
-10C= Solid
10C= Liquid
50C= Liquid
90C= Liquid
110C= Gas
120C= Gas
Explanation:
Below 0 degree C (Celsius), water is frozen means it is in the form of ice. After 0 degree, once we keep it in room temperature, the ice starts becoming liquid (water), and once we heat water, after 100 degree C (Celsius) water starts boiling and thus starts entering gaseous state.
