Answer:
It would take approximately 289 hours for the population to double
Explanation:
Recall the expression for the continuous exponential growth of a population:
where N(t) measures the number of individuals, No is the original population, "k" is the percent rate of growth, and "t" is the time elapsed.
In our case, we don't know No (original population, but know that we want it to double in a certain elapsed "t". We also have in mind that the percent rate "k" would be expressed in mathematical form as: 0.0024 (mathematical form of the given percent growth rate).
So we need to solve for "t" in the following equation:
Which can be rounded to about 289 hours
It is false that the main goal of health psychology is to design machines that are easier for people to use.
Health psychology studies the human psyche and its effects on a person's overall health - it doesn't have much to do with making machines.
Density = (mass) / (volume)
4,000 kg/m³ = (mass) / (0.09 m³)
(4,000 kg/m³) x (0.09 m³) = mass
mass = 360 kg
force of gravity = (mass) x (acceleration of gravity) = (360 kg) x (9.8 m/s²) = (360 x 9.8) kg-m<span>/s² </span><span>= </span>3,528 newtons .
Answer:
hhere is your answer this might help u..
Explanation:
this is because..
mercury forms <u>convex meniscus</u>... with object.. which make it not to wet any type of surfaces..
but...
water forms <u>concave meniscus.</u>.. which act opposite like mercury and wets the body...
and another reason is that water has <em><u>adhesive</u></em> properties...
