1). Take a sample of the substance. The sample should be the largest
possible that will allow it to be be easily handled and the following steps
to be performed with it.
(The density doesn't depend on the size of the sample, and every sample
of the same substance has the same density. But using a larger sample
can improve the accuracy of the measurements you make, and therefore
improve the accuracy of the density you derive for the substance.)
2). Ask or measure the mass of the sample.
3). Ask or measure the volume of the sample.
4). Divide the mass by the volume. Their quotient is the density
of the substance.
So when the body moves in a straight line the average velocity is equal to the average speed. average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. this happens when a particle moves along a straight line in a fixed direction.
Yes, Oxygen atoms may bond to themselves and they do, forming diatomic Oxygen gas.
Answer:
The fatel voltage is 100 volts.
Explanation:
Given that,
Current passes near the heart is,
An electrician working with sweaty hands makes good contact with the two conductors he is holding, one in each hand.
Resistance, R = 2000 ohms
We need to find the fatal voltage. It can be calculated using Ohm's law as :
So, the fatel voltage is 100 volts. Hence, this is the required solution.
