Answer:
According to Newton's third law, for every action force there is an equal (in size) and opposite (in direction) reaction force. Together, these two forces exerted upon two different objects form the action-reaction force pair.

Answer:
★ In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies.

Answer:
The correct solution is "37.5 km".
Explanation:
Given:
Distance between the trains,
d = 75 km
Speed of each train,
= 15 km/h
The relative speed will be:
=
=
The speed of the bird,
V = 15 km/h
Now,
The time taken to meet will be:
hence,
The distance travelled by the bird in 2.5 h will be:
⇒
Answer:
It's had to be a Nuclear change since by nuclear fusion we can convert lead to Gold.
Therefore <u>Option B. Nuclear Change</u> is Answer.

We can answer this problem by dimensional analysis. As we can see, the units of the electric field strength is newtons per coulomb. If we multiply a value with units of coulomb we will obtain newtons which is a units of force.
Force = 9.4x10^7 N / C (8.1 x10^-9 C)
Force = 0.7614 N
