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/

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
