That type of bending is called "diffraction" of waves.
If Earth was twice as far from the sun, the force of gravity attracting the Earth to the sun would be only one-quarter as strong. The correct answer will be C.
Newton's three forces, normal, tension and friction, are present in a surprising number of physical situations
Newton's Laws, that describe the relationship between an obejct and the forces acting upon it, apply in almost every physical situation, from quantum mechanics to electricity.
The correct answer is:
Newton’s laws can explain the forces that occur between objects every day
Answer:
A
Explanation:
I'm pretty sure it's A because when you look up the properties of alkali metal it states stuff about its melting points and what to expect. (correct me if I'm wrong but I had this same question on a test and I'm sure this is the answer lol)
Answer:
Explanation:
Given
A plastic rod is rubbed with a woolen cloth and the Glass rod is rubbed with silk rod.
After the rubbing Plastic rod will acquire the negative rod and the glass rod will acquire a positive charge.
(a)If an object repels the plastic rod then it must be of the same nature i.e. of negative charge.
As the object is negative in nature it will attract the glass rod.
(b)Another object is attracting the plastic rod i.e. the object must be positively charged as a plastic rod. This happens because the opposite charge attracts and same charge repel each other.
It will repel the glass rod
