The correct choice is
b. the larger beaker of water contains more heat than the smaller beaker
Reason :
Heat is given as
Q = m c T
where Q = heat contained
m = mass of water
c = specific heat of water
T = change in temperature.
since the specific heat and temperature is same for both the beakers, we need to look at which beaker contains more amount of water. the larger beaker has more mass of water, hence heat contained in the larger beaker is greater.
<span>The speed is a scalar quantity which by definition is the distance traveled per unit of time. Unit for speed is: km/h. (how many km the object is moved for one hour) or mph (miles per hour).
From the given option D. A dog runs an average 8 mph. (this means that a dog is moving 8 miles per hour).

Answer:
D) 12.3 m/s downward
Explanation:
We use the next free fall equation
where 
is the height of the cliff, 
the initial velocity, 
the acceleration of gravity (
) and 
is time.
For the fist rock 
since the rock was dropped, and 
, so we have:
simplifying
the height of the cliff is 44.145m
Now, about the second rock we know that is the same height and now the time es 
, and we need to find
From the fist equation
we clear for
and substitute known values
wich rounds up to 
the direction is downward because the rock is thrown so that it falls through the cliff.
Poisonings mostly have no taste or smell. Thallium is one of the poisons that are hard to detect. Most of these poisons are always prescribed to many patients and can be misused. We also have to take into consideration thay poisoning attacks our immune system and internal organs. Side effects of poisoning are flue like. So when the individual is feeling ill. nobody is going to think it’s poison at first until about 30 mins to an hour. that’s why it takes so long to be undetected at first. because of the symptoms, smell, taste..... it can really be easy to poison someone
