Answer:
yes
Explanation:
using law of HC(heat capacity), which is
- heat loss=heat gain
- energy H=MCQ
Where M is mass of substance,C is specific heat capacity, and Q is temperature change
In case of two substance
- the H = Mc*Cc*Q+Mw*Cw*Q(provided the initial and final temperature are given)

Answer:
Option 2 - Standard deviation
Explanation:
To find : Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?
Solution :
Standard deviation is defined as,
- It is a mathematical measure that is used to evaluate the difference between the mean value of a set of number and each value in the group.
- It is calculated as the square root of variance by determining the variation between each data point relative to the mean.
The measure of dispersion that indicates how much scores in a sample vary around the mean of the sample is the standard deviation.
Therefore, option 2 is correct.
Answer:
overtone- one over the first
n skips by twos
4 antinodes
500 Hz
Explanation: Hope this helps :)
This is either a trick question or a very hard one. In the first case: An electric field cannot occur inside a conductor (or by using the superposition principle you find out that at this point your electric fields cancel each other out)... Or you must use the laplace equation and proper boundary conditions to solve for the electrostatic potential
