Mass of the object is given as
now the speed of object is given as
here we know that
now we will have
now we will have kinetic energy of the object as
now the power is defined as rate of energy
so here we can find power as
so above is the power used for the object
The type of mass movement that happens very slowly is Creep.
Explanation:
Mass movement, usually known as mass wasting, is that the descent movement of a mass of surface materials, like soil, rock or mud. This mass movement generally happens on hillsides and mountains because of the influence of gravity and may happen terribly slowly or terribly quickly.
Answer:
a) v=1.36f
b)m=.36
c) real
d) Inverted
Explanation:
a)
In this question we have given,
object distance from converging lens,u=-3.78f
focal length of converging lens,=f
we have to find location of image,v=?
and magnification,m=?
we know that u, v and f are related by following formula
.............(1)
put values of f u in equation (1)
we got,
or
v=1.36f
b) Magnification, 
c)
Here the object is located further away from the lens than the focal point therefore image is real image and inverted.
d) image is inverted
The reaction of the half-life is a description of the needed time for the reactant to deplete.In the first order reactions formula, k is considered as the first order rate constant whose unit is denoted as 1/s. Hope this helps.
Answer:
Chain reaction is possible by neutron
Explanation:
Nuclear reaction is mainly two types,
⇒ Nuclear Fission : heavy atom split into two light atom.
Ex. Uranium, thorium
⇒ Nuclear fusion : lighter atom combine together
Ex. Hydrogen to helium
In fusion reaction the large amount of energy is produced as compare to fission reaction.
Sun gets brighter by fusion reaction.
In case of uranium fission reaction is possible by colliding neutron.
