Explanation: I JUST TOOK THE PF EXAM AND GOT IT CORRECT!!!!
The correct answer of this question is: Work = Force . Distance
EXPLANATION:
The work is said to be done by a body if the force applied on the body has a component along the direction of displacement.
Let us consider a body of mass m.
The body is acted upon by a constant force F . Due to this force, the body undergoes a displacement of S .
Let is the angle between force and displacement.
Hence, the component of force along the direction of displacement is .
The work done by that body is calculated as -
Work done W =
=
= [ ∵
Let .
Hence, work done W = FScos0
= FS [ cos0 = 1]
Hence, the relation between work, force and distance can be written as -
Work = force . distance
B. Nonmetallic elements tend to have a positive valence and tend to be electron borrowers.
C. Metals tend to have a negative valence and tend to be electron borrowers.
D. The greater the number of electrons an atom has to borrow or to lend, the greater the activity of the atom
Answer:
A
Explanation:
B. transform fault area
C. seafloor spreading zone
D. region of paleomagnetism
Answer:
Option (A)
Explanation:
Earth crust is comprised of numerous lithospheric plates. These plates constantly move over the viscous asthenosphere layer. This movement of plates is due to the convection current generated in the mantle due to the radiation of the heat from the earth's core.
This plate motion takes place in three different ways, namely
1) Convergent plate motion
2) Divergent plate motion
3) Transform plate motion
In a convergent plate motion, two plate collides with one another. Due to this collision, the denser plate gets subducted below the less denser plate forming a subduction zone. This region is also known as the Benioff zone.
Hence, the correct answer is option (A).
elliptical
square
the answer is circular
