Answer:
a) Q = 80,000 cal
b) Q = 100,000 cal
c) Q = 540,000 cal
d) Q = 720,000 cal
Explanation:
a)1 kg from 0⁰ Ice to 0⁰ water, the heat produced is latent heat of fusion
= 1 * 80
= 80 kCal = 80,000 cal
b) 1 kg of O°C ice water to 1 kg of 100°C boiling water
Specific heat capacity, c = 1000cal/kg.C
c) 1 kg of 100°C boiling water to 1 kg of 100°C steam
Latent heat of vaporization is needed for this conversion
d) 1 kg of O°C ice to 1 kg of 100°C steam.
Q = 
Q = 80,000 + 100,000 + 540,000
Q = 720,000 cal
Answer:
c) True. factor four
Explanation:
The energy density of an electromagnetic wave is given by
u = ½ ε₀ E² = B² / 2μ₀
Where ε₀ is the dielectric constant and μ₀ the magnetic permittivity.
Let's apply this equation to the present case
If we double the electro field
E ’= 2 E₀
u’= ½ ε₀ (2E₀)²
u’= ½ ε₀ Eo² 4
u’= 4 u₀
Therefore the energy is multiplied by four
Let's check the answers
a) False
b) False
c) True
d) False
e) False

The correct option is B.
There were 4 treatment conditions compared in the experiment.
F ratio plays an essential role in performing a particular dataset of ANOVA. F ratio is particularly a ratio which is obtained by the between-group variance or it is also called MSB and also within-group variance known as MSW. Any F-ratio which is computed is compared with the critical F-ratios from the table as it will check out if there are any variations available between the groups or not.
The researcher reports an F-ratio where the degrees of freedom = 3, 36.
F-ratio is obtained by the calculation of dividing the Mean squared errors because of the treatment by the Mean squared error which occurs due to error.
For the particular case, the researcher reports an F-ratio having degrees of freedom = 3, 36. It is indicating that the treatments are being distributed with degrees of freedom which is 3 and specified errors are distributed with degrees of freedom which is 36.
Let the treatments which were involved in the study can be denoted by k.
Let the total number of individuals involved in the study can be taken as N.
Then, the treatments will be having degrees of freedom as,
= k-1
3=k-1
k=3+1=4
Therefore, the required treatment condition number that was compared is 4.

When driving on multilane street with two way traffic, the best response to this scenario is to drive ahead but if there are vehicles in front of you, it is also best to drive along behind the multilane vehicles. It is not best to over take or to consume the middle lane because it is a multilane street. In which there are only two lanes and over taking it could cause accidents when not careful, and consuming up the middle is not appropriate to take because the lane is for two lanes.
