The slope of the line on a velocityversus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
Answer:
<em>1. If the switch is closed, the total resistance of the circuit remains the same</em>
<em>2. The brightness of the bulb A when the switch is closed remains the same.</em>
<em></em>
Explanation:
An ideal battery has no internal resistance, and hence, maintains a constant value of voltage without diminishing. The total resistance of the circuit will remain constant since this is an inherent unchanging property of a conducting circuit provided there is no change to its configurations. The brightness of the bulb A will remain unchanged since we are considering an ideal battery. In practice, ideal batteries don't exist, reason why battery powered light bulbs gradually dim with time as the internal resistance increases, till it eventually dies.
Of the waves listed, the one
with the longest wavelength is the radio wave. The answer is letter B. They are
the longest wave in the electromagnetic spectrum. It can either be a long wave
or a short wave.
