Answer:
A tectonic plate (also called lithosphere plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Explanation:
-- Top picture:
'a' and 'b' have the same magnitude, and both are positively charged.
-- Bottom picture:
The charge on the particle is negative.
Answer: Both are Brittle
Explanation:
Metals are lustrous, malleable and ductile. Metals are good conductors of heat and electricity.
Non-metals are poor conductors of heat and electricity. Non-metals are brittle and non-lustrous elements.
Elements which have properties between metals and non-metals are known as metalloids.
Some mettaloids are lustrous and conductors of electricity. One property that these elements share with non-metals is that these are brittle i.e. they can easily break.
field is force at a distnce = falling under grav ... contact is force at point of contact
