Answer:
To calculate speed, all you have to do is divide distance by time.
Explanation:
Velocity is just speed in a particular direction. For example, if in 3 hours you ran 6 kilometers west, your velocity was 6 km/3 hours = 2 km/hour west.
Answer:
25N
Explanation:
Assuming the lab is on earth:
w = mg = 2.5 (9.81) = 25N
The choices can be found elsewhere and as follows:
<span>A 10 timesB 2 timesC 4 timesD 8 timesE 16 times
I believe the correct answer from the choices listed above is option E. If you turn up the temperature of an oven from 250 degrees kelvin to 500 degrees, the oven will be radiating 16 times.</span>
Answer:
<em>Reaching activation energy</em><em> is necessary because reactants require a </em><em>minimum</em><em> </em><em>amount of energy</em><em> start breaking a</em><em> chemical bond.</em>
Explanation:
Activation energy is the minimum amount of energy required by the reactants to initiate a chemical reaction. The unit of activation energy is joule or kilo joule per mole or kilo calories per mole. Activation energy depends on temperature.
The temperature dependence of activation energy is given by Arrhenious equation. Activation energy is a threshold value of energy. For any reaction to occur this is the minimum amount of energy required.
