Density because it can measured and felt.
Answer:using Newton third law
Let initial velocity of block be u1=3m/s
Mass of moving block m1 =1kg
Final velocity of block =V
Mass of stationary block m2= 4kg
Since they stick together, their final velocity will be the same.
m1u1 + m2u2=(m1+m2)v
(1*3)+(0*4)=(1+4)v
3=5v
Divide both sides by 5
V=0.6
Final velocity is 0.6m/s

Answer:
(a) 
(b) 
Given:
Time period of Pulsar, 
Equatorial radius, R = 15 Km = 15000 m
Spinning time, 
Solution:
(a) To calculate the value of the centripetal acceleration, 
on the surface of the equator, the force acting is given by the centripetal force:
(1)
where
(2)
Now, from (1) and (2):
(b) To calculate the tangential acceleration of the object :
The tangential acceleration of the object will remain constant and is given by the equation of motion as:
where
u = 
Answer:
A.The new discovery might cause the theory to be dismissed since it contradicts it.
Or
D.The new discovery might further deny the theory since it presents evidence that contradicts it.
Itl be hard for them to decide you know, since this bigbang theory by darwin is widespread and cant be easily opposed..
