Lunch of a patient has 3 oz skinless chicken, 3 oz of broccoli, 1 medium apple, and 1 cup of nonfat milk
Energy content of 3 oz skinless chicken is = 110 kcal
Energy content of 3 oz broccoli = 30 kcal
Energy content of 1 medium apple = 60 kcal
Energy content of 1 cup non-fat milk = 90 kcal
So the kilocalories of energy patient obtained from lunch
= 110 kcal+ 30 kcal + 60 kcal + 90 kcal = 290 kcal
1. when the ball is just starting to fall, it has high potential but low kinetic energy. when it hits the floor, it has high kinetic but low potential energy
2. heat energy
3. reflective-transparent would be best, as they can reflect some light while let other light through, reflective-opaque would be useless in any circumstances because no light at all would be able to get through
Answer:
f = 80 flutter/ second
T= 0.0125 sec
Explanation:
Given data:
Fluttering of wings = 4800 time per minute
Frequency of wings = ?
Period for one wing in sec = ?
Solution:
There are 60 seconds in one minute, thus frequency of wings
4800/60 = 80 flutter per second
Period:
T = 1/f
T = 1/80
T= 0.0125 sec
pH scale is used to measure the acidity or alkalinity on a scale of 0-14 where 0-6.9 is the acidic region , 7.1-14 is the basic region and 7 is for the neutral substance. We can calculate the concentration of proton from pH.
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
where ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
is the concentration of proton
As per the question ,the pH of coffee is 5.6 and we need to find the concentration of proton so putting the values in the above equation, we get
![5.6=-log[H^+]](https://tex.z-dn.net/?f=5.6%3D-log%5BH%5E%2B%5D)
![-5.6=log[H^+]](https://tex.z-dn.net/?f=-5.6%3Dlog%5BH%5E%2B%5D)
![antilog(-5.6)= [H^+]](https://tex.z-dn.net/?f=antilog%28-5.6%29%3D%20%5BH%5E%2B%5D)
![[H^+]= 2.511\times10^-^6 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D%202.511%5Ctimes10%5E-%5E6%20M)
