We need to find the net force. We are given a starting and final velocity, the length of time the acceleration took place and the total weight of the car. We can use F=ma to calculate the net force. Since...
A vector describes both magnitude and direction, whereas a scalar only describes the magnitude. A common example is speed and velocity. Speed is a scalar, it describes only how fast something is going and...
stars begin as a giant cloud of gas which is also a protostar. gravity will pull the gas in on intelf which increases heat and pressure to such great quantities that nuclear fusion can begin. hydrogen is ...
Firstly, we must set-up an experiment and would need the following apparatus: The cell, a voltmeter, an ammeter and a variable resistor (a rheostat for this example). Setup the experiment so that the cell...
The moment of a couple is the force times the perpendicular distance between the lines of action of the force.
