Wooden cube, density 620kg/m², is 0.08m tall, 0.12m wide, and 0.12m thick. It floats in a liquid with density 900kg/m². A string attached to the bottom of the container prevents the cube from floating up to the surface. Find the tension in the string. [8]

A heavy rainstorm dumps a total of 73 cm of rain on a rectangular shaped city area measuring 9 km by 17 km over a 27 hr period. Determine the average rate of rain fall in metric tons per second. NOTE: 1 cm3 water has a mass of 1 gram and 1 metric ton = 1000 kg. I attached how far I have gotten on this problem and I don't know if I did that correctly or not and am not sure where to go from where I am at.

Container 1 has rectangular base with area of 4.03m ^ 2 and its height is 1.3 m. Container 2 has a volume of 24m ^ 3. What the sum of the volume of the two containers with correct number of significant figures?

Physical units in mechanics are usually some combination of the dimensions time T, mass M, and length L. Consider the physical quantities m, r, u, a, and t with dimensions [m] = M, [r] = L, [u] = LT-, [a] = LT-2, and [1] = T. Enter the dimensional expression of the quantity on the right-hand side of each equation. Your answers may contain only M, L, T, and exponents. Assume that each of the following equations is dimensionally consistent. Lo = mur [Lo] = W = mar [W] = T

Determine the absolute uncertainty for the calculated value in the following scenarios. Express as (computed result) ± (absolute uncertainty) (units).   You measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty?   Please use the formula I posted ! Thank you!

At 9:13 A.M., a sports car is traveling 30 miles per hour. Two minutes later, the car is traveling 90 miles per hour. The mean value theorem guarantees that at some time during this two-minute interval, the car's acceleration is exactly A miles per hour squared. Compute the value of A. A = mi/h² Need Help? Read It

Create a C++ program for managing a grocery store's Inventory system. The Inventory information is stored in a text file named "grocery inventory.txt." Each line in the file represents a grocery item with the following format: "SKU, Name, Category, Quantity Price" The program should allow the user to add new items, update the quantity of existing Items, and display the total value of the inventory. Ensure that the program checks for the existence of "grocery inventory.txt" and handles cases where the file is empty. Utilize functions to organize your code effectively, with comments explaining each function's purpose. You can use data structures like arrays or structs to store and manipulate inventory data. The program should output the updated inventory information to a file named "updated_grocery_Inventory.txt." Ex: grocery Inventory.txt: 101, Apples, Fruits, 50, 0.75 102, Bread, Bakery, 20, 2.50 103, Milk, Dairy, 30, 3.99 (updated grocery inventory.txt after adding 100 packs of Eggs…

An Olympic-size swimming pool is 50 m long, 25 m wide, and 2 m deep. In terms of volume, this pool, when full, holds how many kilogallons of water? Use the following equivalences: 1 gallon = 3.8 L     1 kilogallon = 103 gallon      1 L = 103 mL     for water: 1 mL = 1 cm3      1 m = 100 cm   [Numerical Problem: Just write the numerical answer without units. Express your answer to 2 significant figures in standard notation]

This was wrong. Can you solve this again with these numbers? What is the root mean square velocity, vrms, for Hydrogen molecules (H2) at 20oC? Hint: How many amu does an H2 molecule contain. 1 amu = 1.67 x 10-27 kg Boltzman's Constant, k = 1.38 x 10-23 J/K Give your answer in m/s to 4 significant figures (NO DECIMALS)
