a. The attachment shows a cube floating in a fluid. Derive an expression relating the submerged depth X, the specific weight of the cube, and the specific weight of the fluid.
b. If the cylinder in the second attachment, made of a uniform material, is placed in fresh water at 95 degrees Celsius, how much of its height would be above the surface (ignore kerosene note and 600mm note - refers to another problem?. Assume the specific weight of water is 9.44 kN/m^3.© BrainMass Inc. brainmass.com October 24, 2018, 5:54 pm ad1c9bdddf
a. Let us assume that the specific weight of the cube and fluid be sc and sf respectively.
Volume of the cube Vc = s*s*s = s^3
The weight of the cube W = sc*Vc
=> W = sc*s^3 ......................(1)
The upthrust of fluid on cube = weight of the fluid displaced W'
W' = sf*V'
where, V' = volume of cube ...
For (a), this solution solves using the equation: volume of the cube Vc = s*s*s = s^3. For (b), the problem is solved in general terms because the specific weight of the cylinder is not given.
Human Development in The Classroom
I need help with the information on each question and examples to prepare for writing a paper:
1. Analyzing the importance of understanding the stages of human development in the classroom.
2. Analyze some of the problems that might result from a teacher's lack of such understanding.
3. Focusing on one stage ( early childhood), include a discussion of teacher behaviors that would promote students' thinking abilities, behaviors that would help students achieve greater success, and behaviors that would promote the social and emotional well-being of the individual student as well as improve the classroom environment for children in that stage.
4. Include classroom practices and materials that you feel promote diversity and equity within the educational experience.
Please focus on the early childhood like kindergarten. Thank you.View Full Posting Details
