Answer:
The potential energy is zero since the rock isn't moving.
Answer:
Magnetic field at the center will be 
Explanation:
We have given that diameter of the loop d = 14 cm = 0.14 m
So radius 
Current in the loop i = 2.40
We know that magnetic field at center of circular loop is given by
So 
Magnetic field at the center will be
Answer:
1)FALSE
2)TRUE
3)FALSE
4) FALSE
Explanation:
1) Retrieving an entry at a given position is not slow ( it is done using index number ) hence the answer is FALSE
2) Adding an entry at the end of the list is Fast this is because in using array implementation a new entry is made immediately after the last position and it is done very fast as well. hence the answer is TRUE
3) Retrieving an entry at a given position ( from an ADT list ) that is been implemented using Vector is very fast this is simply because Indexing in vector is done at a fixed time hence the answer is FALSE
4) Adding an entry at the end of the list is slow using vector hence answer is FALSE
Answer:
If the beer is in the crystal clear glass, unprotected from the sunlight then it will starts skunking within 30 seconds. The reason behind the skunking of the beer is a photo chemical reaction. So one can avoid the skunking of beer by packaging it in the cans or opaque bottles.
Explanation:
Answer:
C)0.59 N
Explanation:
By the Achemides principle we know that the buoyancy force on an object which is immersed in a incompressible fluid at rest is equal to the weight of the fluid displaced. So all we have to do is to find the mass of 60ml.
Density = mass / volume
Mass = density × volume
= 1 g/cm³× 60 cm³
{ as 1ml=1cm³}
= 60 g
So force equals to,
Force = weight = mass × gravitational acceleration
= 0.06×9.8 = 0.59 N
