physics
A solar heating panel on a roof is used to heat 40 kg of water initially at 22 degress celsius, using the sun, which absorbs 750 joules per second. What would the temperature of this water be after 1 hour?

math
x^2+y^2=36 is a circle. How can you tell without actually plotting? Where is the center?

Physics
1. A model of a helicopter rotor has four blades, each 2.50 m in length from the central shaft to the blade tip and is rotated in a wind tunnel at 1800 rev/min, a. what is the linear speed of the blade tip in m/s? b. what is the radial acceleration of blade tip?

physics
A) yes. B)gravity acts straight down at w=mg. centripetal force is acting towards the center of where it rotates. It would be from the tension. C)It is equal the whole way through. Since it is moving in a uniform circle, the force is equal at any point throughout the rotation.

physics
These two bulbs are 2.0m apart. Sorry for not putting that in the question.

physics
From what distance can these light bulbs be marginally resolved by a small telescope with a 6.0 cm-diameter objective lens? Assume that the lens is limited only by diffraction and wavelength = 600nm

MATH
Yes they can. They are two angles next to each other that share the same side that will add up to 180 degrees. For instance, angles of measurements 45 degrees and 135 degrees are together and form a straight line making them both adjacent and forming a linear pair.
