A cube of side length of 50 cm is lowered carfully with top and bottom parellel to the surface into a clear, freshwater lake. A) when the top of the cube is 4.5 cm below the surface what is the total force due to the water in the top of the cube? B) What is the total force on the bottom? C) what is the net force due to water on the cube? Explain the effect of water on the...
QUESTION 4: (10 points) A force of 30 Newtons is required to stretch a spring from its natural state to a length of 15cm. A force of 80 Newtons is required to stretch it to 20 cm from its natural state. How much work is required to stretch it from 15cm to 20 cm? Show ALL your steps and calculations.
Two rooms, each a cube 4.5 m per side, share a 13-cm-thick brick wall. Because of a number of 100-W lightbulbs in one room, the air is at 35 ∘C, while in the other room it is at 12 ∘C. How many of the 100-W bulbs are needed to maintain the temperature difference across the wall? Express your answer as an integer (in bulbs)
An Aluminum cube (6 sides) having a side dimension of 3.0 cm is initially at a uniform temperature of 100 ◦C. It is suddenly exposed to an airstream of 10◦C with h = 30 W/m2 · ◦C. Check for the suitability of the lumped capacity analysis and determine the time (sec) for the cube temperature to drop to 25◦C?
A cube of side 9.50 cm is placed in a uniform field E= 7.50 x 10' N/C with edges parallel to the field lines (field enters into the right face of the cube, passes through it and exits from the left side). What is the net flux through the cube? Express your answer to three significant figures and include the appropriate units. μΑ ? net - Value Units Submit Request Answer Part B What is the flux through the right...
A solid aluminum cube is attached to spring-like device and is able to oscillate horizontally with negligible friction. Each side of the cube is 1.50 cm long. The cube is initially pulled to a point where it stretches the spring-like device by 2.55 cm where it is held at rest with a horizontal force of 1.35 N. What is the frequency at which it oscillates when it is released? (Assume the density of aluminum is 2.70 g/cm3.) answer in Hz
