Answer:
14523.55J
Explanation:
The work exerted by the jogger against gravitational forces is represented by the following equation:
where m signifies mass, g represents gravitational acceleration taken as 
, and h denotes the elevation of the hill.
Given that the hill measures 132m in length and is inclined at an angle of 12 degrees to the horizontal, the height can be calculated as follows;
Substitute this value into equation (1) along with all other required parameters to arrive at the result;
The first word in the blank is "pours out of you," while the second word to fill in is "diffuse." This implies that a person with an effusive nature tends to openly express their feelings, just as spilled motor oil will spread out over gravel.
Answer:
3.3kg
Explanation:
Given information:
Spring constant = 400N/m
Extension = 8cm = 0.08m
We need to determine:
The mass that the spring can support =?
Solution:
To arrive at the solution:
F = kE
F represents the force
k is the spring constant
E is the extension
So;
F = 400 x 0.08 = 32N
Mass;
Force = mass x gravitational acceleration
32 = mass x 9.8
Therefore, mass = 3.3kg
