Answer:
200 m/s
Explanation:
Given that,
A plane is moving due north, directly towards its destination. Its airspeed is 200 mph. A constant breeze is blowing from west to east at 60 mph.
We need to find the rate at which the plane is moving towards North. It can be given by :
Where
is the angle with the North
Hence, the plane is moving at a rate of 200 m/s.
Answer:
The correct answers to then question are
A and B
Explanation:
As highlighted, the atoms of the two isotopes are chemically identical and they have similar characteristics due to the presence of equal number of protons and electrons (92 each). Therefore factors influenced by the chemistry of the atoms of the isotopes such as the distance between atoms and the stiffness of the inter-atomic spring is identical for both and
An analogy of the spring constant and the inter-atomic distance is to consider the atoms of the metal to be interconnected by elastic material and as such the stiffness of the elastic material and the inter-atomic distance are determined by surface factors occurring on the surface
