(1 point) Viewing Window The underwater viewing window of a dolphin aquarium is rectangular and has a width W 15 m (into the page), height H 3 m, and thickness t. The window is located such that its top edge is h = 15 m below the water surface. As a poor design choice, the window is bonded to the walls of the aquarium along its top, bottom, and side surfaces (all surfaces except the two that are necessary for...

Constants Periodic Table A spring (80 N/m) has an equilibrium length of 1.00 m. The spring is compressed to a length of 0.50 m and a mass of 2.1 kg is placed at its free end on a frictionless slope which makes an angle of 41° with respect to the horizontal. The spring is then released. 0.50 m 0 = 41° Part A If the mass is not attached to the spring, how far up the slope from the compressed...

A Review Constants Periodic Table Only about 10% of the electromagnetic energy from an incandescent lightbulb is visible light. The bulb radiates most of its energy in the infrared part of the electromagnetic spectrum. Part A If you place a 100-W lightbulb 2.1 m away from you, what is the intensity of the infrared radiation at your location? Assume that bulb radiates only visible light and infrared radiation. Express...
