Answer:
Total distance = 400+700+1200= 2300km
Explanation:
the resultant of d 1st right angle triangle + 1200
= 806.2 + 1200 = 2006.2km
It is C) because that truck has more mass
Answer:
a and b are the correct answers
Explanation:
Well, the relationship between the net force and mass and acceleration of an object are directly related, as per the equation - Fnet = ma.
Thus the solution is A. As the net force of an object decreases, the object's acceleration also decreases, mass is kept constant.
Answer:



Given:
Weight of solid in air, 
Weight of solid in water, 
Weight of solid in liquid, 
Solution:
Calculation of:
1. Relative density of solid, 


2. Relative density of liquid, 


3. Density of liquid in S.I units:
Also, we know:

where
= density of liquid
= density of water
Now, from the above formula:
