Answer: 735 N
Explanation:
Weight 
is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass 
of the body by the acceleration of gravity 
:
In the case of our planet Earth, the acceleration due gravity is 
. So for a man whose mass is 
, his weight is:
The freezing point of the water is 0 C , and it equals to 273 K
Then, To convert from Kelvins degrees to Celsius degrees we use the relation
Also,
Answer:
scientists will use absolute dating to find how old a fossil exactly is.
Answer:
12.5
Explanation:
Pressure: Force/Area = 650/52
=12.5
It is trajectory acceleration. A friction track is a device to study motion in low friction environments, I believe. Does this help?
