Answer:
Explanation:
given,
F = 14.1 i + 0 j + 5.1 k
displacement = 6 m
Assuming block is moving in x- direction
we know,
dW = F dx
hence, work done by the force is equal to
Answer:
Geothermal
Explanation:
Geothermal is obtained from the heat from the ground which makes it friendly
The troposphere is the layer of the atmosphere which contacts the surface of the Earth. This layer is <span>0 to 12 km (0 to 7 miles).

Answer:
Explanation:
In a sonometer , expression for speed of wave produced can be given as follows .
v =
v is velocity , T is tension in wire , m is density per unit length .
Here v is inversely proportional to square root of m . So if m becomes m / 4
velocity changes as follows .
velocity =
=
= 2v
velocity becomes two times . Hence to make velocity two times , mass per unit length has to be changed to one fourth value , keeping tension constant .
