Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
Explanation:
Henry's Law (formulated in 1803 by William Henry) states that aa constant temperature, the amount of gas dissolved in a liquid is directly proportional to the partial pressure exerted by that gas on the liquid.
Mathematically it can be formulated as
C = H⨯P
being:
C: the molar concentration of dissolved gas A,
P: the partial pressure of it
H: Henry's constant
Substituting:
C = P * H
C = (2.50 * 0.9869) * 58.0
C = 143.1
Answer:
the solubility (in m units) is
C = 143.1
Answer:
42.05 m/s
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Height (h) = 239 m
Acceleration due to gravity (g) = 3.7 m/s²
Final velocity (v) =?
The velocity with which the camera hits the ground can be obtained as follow:
v² = u² + 2gh
v² = 0² + 2 × 3.7 × 239
v² = 0 + 1768.6
v² = 1768.6
Take the square root of both side
v = √(1768.6)
v = 42.05 m/s
Therefore, the velocity with which the camera hits the ground is 42.05 m/s

Answer:
v₀ = 13.24 m / s
Explanation:
Let's use Newton's second law to find the average acceleration during the crash
F = m a
. a = F / m
a = 8000/73
a = 109.59 m / s²
Now we can use the kinematic equations to find the initial velocity, since when the velocity stops it is zero (v = 0)
v² = v₀² - 2 a x
v₀² = 2 a x
v₀ = √ 2 a x
v₀ = √ (2 109.59 0.80)
v₀ = 13.24 m / s
