Answer:
m = 2.01[kg]
Explanation:
This problem can be solved using Newton's second law which tells us that the force applied on a body is equal to the product of mass by acceleration.

where:
F = force = 12.5 [N]
m = mass [kg]
a = acceleration = 6.2 [m/s²]
![12.5=m*6.2\\m = 2.01[kg]](https://tex.z-dn.net/?f=12.5%3Dm%2A6.2%5C%5Cm%20%3D%202.01%5Bkg%5D)
Answer:
Straight Line
Explanation:
For an ideal gas,
PV = nRT
For a fixed quantity ( constant number of moles) of a gas at fixed temperature
Right side of the equation will be constant
Thus,
PV = C
So, P =
.
Thus P is directly related to 
That's why plot between P and
will be an straight line.
Answer:
(c) always equal to the weight of the liquid displaced.
Explanation:
Archimedes principle (also called physical law of buoyancy) states that when an object is completely or partially immersed in a fluid (liquid, e.t.c), it experiences an upthrust (or buoyant force) whose magnitude is equal to the weight of the fluid displaced by that object.
Therefore, from this principle the best option is C - always equal to the weight of the liquid displaced.
<span>The earth gets most of its energy from the sun. The answer is letter B. This
is because most of the living organisms on earth need sunlight to perform
activities that would balance the ecosystem. Sunlight is the reason for the
climate system on earth, the production of food through cellular respiration
and many more.</span>
