Formula for time
t=d/s
so…
t= 48m/4m/s
the two ms cancel each other out and ur left with s
t=12s
Answer:
Writing reactants on the left, and the products are written on the right
Explanation:
Answer:
a common temperature is reached.
Explanation:
The principle of heat transfer is that heat flows from a substance of higher temperature to that of lower temperature until when a common temperature is reached.
For ice on getting in contact with a hot body; it changes to water at 0°c utilising the latent heat of fusion. After ice has been converted to water at 0°c, water starts increasing in temperature till a common temperature is reached.
Carbon-14 is a naturally occurring carbon isotope.
Carbon-14 has a known half-life.
Carbon-14 is present in all living organisms.
Answer: 1. False, an ammeter must be placed in a series connection to experience the same current which it is measuring
2. True, a voltmeter measures voltage (electric potential) in volts
3. False, a voltmeter should have high internal resistance such that it does not significantly alters current in a circuit.
4. True, a meters measure current
5. True, voltmeter would measure electric potential across a resistor
6. False, since they tend to influence the current in a circuit, ideally it should have very low resistance near zero
