Answer: 1.13 X 10^3 g or 1130 g
Explanation: When you add up everything, you will get 1134.1288 g = 1.11341218 X 10^3. But while adding significant figures, we always look for the least significant figures (here 4.65 has least sig. figures i.e. 3) and take that as a reference to how many significant figures we should have in the answer. (Pretty hard to explain!) Hope you got it!!

Answer:
The given figure shows two men M and N facing two flat and hard walls, wall 1 and wall 2. Man N fires a gun. Man M hears two echoes, one from wall 1 and second from wall 2. The speed of sound in
air is given to be 325 m/s. After the firing of the gun by the man N, the man M will hear the first echo in how many seconds?
Answer:
0.96 m, upward
Explanation:
Initial velocity, u=0
Where 
Substitute the values
Hence,the block moves upward because displacement is positive.
