The specific heat of copper is 0.385 J/g•°C. Which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°C to 29°C? Q = 0.75 g x 0.897 J/g•°C x 29°C Q = 0.75 g x 0.385 J/g•°C x 22°C Q = 0.

What is the overall fusion reaction that converts mass into other forms of energy in the sun's core?

We always see the same side of the Moon because Choose one:A. the Moon does not rotate on its axis. B. the Moon rotates once each revolution. C. when the other side of the Moon is facing toward us, it is unlit. D.

A 54 kg man holding a 0.65 kg ball stands on a frozen pond next to a wall. He throws the ball at the wall with a speed of 12.1 m/s (relative to the ground) and then catches the ball after it rebounds from the wall.

A current of 0.5A is drawn by a filament of bulbfor 10 minute find the charge that flows through the circuit

What is a 2d game. Give a refrence.

Two exactly similar wire of steel and copper are stretched by equal force. if the total elongation is 10cm. find how much each wire is elongated given young's modules for steel = 2*10^10 N/M^2 and Young's modules for copper 2*10^10N/M^2.

Which of the following is the FINAL step in a forecasting system? A. Validate and implement the results. B. Make the forecast. C. Select the forecast model (s). D. Gather the data needed to make the forecast.

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phenomena and post it here.

Unlike the idealized voltmeter, a real voltmeter has a resistance that is not infinitely large. part a a voltmeter with resistance rv is connected across the terminals of a battery of emf e and internal resistance r.
