Numerical problems Solve the following numerical problems:
A box weight 900 N and its base is a square of side 2m. What pressure
does the block exert on the ground.
The weight of a box is 300 kg. The lower surface area is 150 square meter.
What is the pressure exerted by the box? (g = 10m/s)
b.
(Ans. 255 Pa]
(Ans. 20 N/m or 20 Pa]
A 5m x 4m x 3m tank is filled with water. What pressure is exerted by
at its buttom
(Given; density of water = 1000 kg/m3 and g = 100m/s)
30000(P
Calculate the pressure exerted by a liquid at 4m if its density is 700kg/

more than, less

less than, more

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
