I think it’s Malleability
Answer:1 trip around the earth is an angular displacement of 2*pi
3.6525*10^2 days
I
Explanation:24 h/1 day * 3.600*10^3 s/1h = 3.156*10^7 s
Angular speed = angular displacement / time
Angular speed = 2*pi rads / 3.156*10^7 s = 1.9910*10^-7 rad/s
Hey there!
a) The electric field is in direction of decreasing value of potential so the electric field here will points towards 0v from 9 v. But the charge on particle is negative so the force will be towards the 9v point. and so the charge will move towards the 9 V point.
b) Electric potential is a location-dependent quantity that expresses the amount of potential energy per unit of charge at a specified location while.the electric potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. Electric potential is always a relative quantity because no one can find out absolute potential at a point, so in reality only potential difference exists. We can assume potential at certain point (say at infinity it is zero) only then we are able to define potential at every point.
c) The knowlendge of electric potential helps us in finding the work done on the particle which is used in work energy theorem to find out the chanrge in kinetic energy and other stuff.
Hope this helps!
Answer:
Explanation:
Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.
To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape. Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.
This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.
Answer:
Velocity will be 2.886 m/sec
Explanation:
We have given arm length = 0.70 m
And distance from the handle to surface = 15 cm =0.15 m
So total distance r = 0.70+0.15 = 0.85
We know that acceleration is given by 
Here acceleration is acceleration due to gravity so a=g
So 
So velocity will be 2.886 m/sec
