Answer:
(a) There are 3.17 times more shakes in a second than seconds in a year.
(b) Humans have existed for 9067.72 universe seconds.
Explanation:
(a) First we calcule how many seconds are in a year. One year have 365 days, one day has 24 hours, one hour has 60 minutes and one minute has 60 seconds, so:
Now, we calculate how many shakes are in a second:
Finally, we calculate how many more shakes in a second are there than seconds in a year:
(b) Using a simple rule of three we can calculate how many "universe seconds" have humans existed, recall that 1 day has 86400 seconds:
1010 years--------->86400s
106 years----------> x seconds

Answer: a. net force is acting on object A in the same direction of its motion.
Explanation:
The second law of Newton states that the acceleration of a particular object is dependent on two main things which are the mass and force. According to the law, the acceleration of the object will be directly related to the net force while the acceleration is also relates inversely to the mass.
Therefore, based on the information given in the question, a force is acting on object A in the same direction of its motion.
Answer:
427.392 kJ
Explanation:
m = Mass of gas = 4.5 kg
Initial temperature = 200 K
Final temperature = 360 K
R = Mass specific gas constant = 296.8 J/kgK
= Specific heat ratio = 1.5
Work done for a polytropic process is given by
The work input during the process is -427.392 kJ
Answer:
<em>The chef can make 8 casseroles</em>
Explanation:
<u>Units Conversion</u>
We need to recall 1 gallon = 16 US cups.
A casserole needs 1 cup of milk, and the chef has 0.5 gallons of milk. Those 0.5 gallons are equivalent to 0.5*16 = 8 cups, thus the chef can make 8 casseroles.
