Answer:
0.33%
Explanation:
From the question given above, the following data were obtained:
Experimental value = 9.842 m/s²
Accepted value = 9.81 m/s²
Percentage error =?
The percentage error in the calculation can be obtained as follow:
Percentage error = |Experimental – Accepted| / Accepted value × 100
Percentage error = |9.842 – 9.81| / 9.81 × 100
Percentage error = 0.032 / 9.81 × 100
Percentage error = 0.33%
Therefore, the error in the calculation is 0.33%
They differ in the number of their neutrons. Hydrogen doesn’t contain neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have mass numbers of one, two, and three.
Answer:
The answer is
<h2>5.75 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 23 g
volume = 4 mL
The density of the object is
We have the final answer as
<h3>5.75 g/mL</h3>
Hope this helps you
C) Condensation is the opposite of evaporation.
Condensation is the phase when water droplet form. Ex) When you have a glass of ice water the water droplets on the outside of the glass are condensation.
Evaporation is when a liquid heats up and turns into a steam or mist. Ex) When you boil water the steam that comes up from the pot is actually water!!
Therefore condensation is caused by cold temperatures, and evaporation is caused by hot temperatures.
