Name the force that stops a block from sinking into the road surface

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.

The acceleration of an object is the slope of its velocity-time graph. True False
