The amount of heat neededto raise 2.0 kg of a substance by 80 K is 33 kJ. What is the specific heat of
the substance?

Answers

Q = mcθ
 
Where Q = Amount of heat in J
             m = Mass of substance in kg
              θ  = Temperature rise in °C or K
              C = Specific heat capacity in J/kgK

From given data:
Q = 33 kJ = 33 000 J, m= 2.0 kg,   θ  = 80 K,   c = ?

33000 =  2 * c * 80
33000 = 160c
160c   = 33000
       c   =  33000/160 = 206.25

Therefore specific heat capacity is 206.25 J/kgK

your friend wants to know the amount of salt added to her favorite fast food French fries. what would you recommend that she do to find out the amount of salt ?

Answers


Every fast-food chain is required by law to make the nutrition content of the
items on its menu publicly available.

My friend should walk into her favorite place, or into the nearest McRonald's,
Bendy's, Tennessee Fried Turkey, Bulgur King, Plucky Please, White Palace,
Pita Hut, Carl's Senior, Back in the Box, or any of those others, ask to see
the Manager, and ask the manager for a chart of nutritional information that
includes their french fries. 

To be nice about it, she should do this at a time when the place is not too busy,
and the manager doesn't have a lot of more-important things that need to be
doneright now.

Under the french fries, look at the serving size, and the figure for "Sodium"
in that serving, which is the nutrient that your body gets from salt.  Less is
better.  More is worse.  For an adult, the CDC Institute of Medicine says
that 1500mg a day is 'adequate' for an adult.  The US Food and Drug
Administration recommends that adults should get 'no more than' 2300mg
in a day. People who have high blood pressure are supposed to watch it,
and take in a lot less sodium. 

And there are organizations with official-sounding names that totally dispute
all of this.

But to answer your question, that's what she should do to learn the amount
of salt used at the place where likes to get her french fries.

Why does a bullet have more kinetic energy than the recoiling rifle

Answers

They both have the same momentum, not kinetic energy.
When bullet is fired it weights let's say 10 grams (0,01 kg) and has velocity of 1000m/s.
The rifle which weights 10000 grams (10kg) has velocity 1 m/s.
The momentum is equal.

But to calculate kinetic energy you have to use formula
 
Lets calculate:
Bullet's kinetic energy= 1/2*0,01*1000^2 = 5000 J
Rifle's = 1/2*10*1=5 J

So the velocity has much larger impact on kinetic energy than mass.
