Answer:
The force is ![F = 1397 lb](https://tex.z-dn.net/?f=F%20%20%3D%20%201397%20lb)
Explanation:
From the question we are told that
The length of the box is ![l = 19 \ in](https://tex.z-dn.net/?f=l%20%20%3D%20%2019%20%5C%20in)
The width of the box is ![w = 5 \ in](https://tex.z-dn.net/?f=w%20%3D%20%205%20%5C%20in)
The height is ![h = 4\ in](https://tex.z-dn.net/?f=h%20%20%3D%20%204%5C%20in)
The pressure experience on one of the sides is mathematically represented as
Where A is the area of the box which is mathematically evaluated as
![A = l * w](https://tex.z-dn.net/?f=A%20%3D%20%20l%20%2A%20w)
substituting values
![A = 5 *19](https://tex.z-dn.net/?f=A%20%3D%20%205%20%2A19)
![A = 95 \ in^2](https://tex.z-dn.net/?f=A%20%3D%2095%20%5C%20in%5E2)
This pressure is equivalent to the atmospheric pressure which has a constant value of ![p = 14.7 pi](https://tex.z-dn.net/?f=p%20%3D%2014.7%20pi)
This implies that
![14.7 = \frac{F}{95}](https://tex.z-dn.net/?f=14.7%20%20%3D%20%5Cfrac%7BF%7D%7B95%7D)
=> ![F = 14.7 *95](https://tex.z-dn.net/?f=F%20%20%3D%20%2014.7%20%2A95)
=> ![F = 1397 lb](https://tex.z-dn.net/?f=F%20%20%3D%20%201397%20lb)
Answer:
Scenario A, B and E is True.
Explanation:
Scenario A) True. Removing carbon dioxide from atmosphere decreases greenhouse effect of atmosphere. Thus, temperature rise decreases.
Scenario B) True. The more evaporation creates the more greenhouse effect. Therefore, temperature rise increases.
Scenario C) False. Removing carbon dioxide from atmosphere decreases greenhouse effect of atmosphere. Thus, temperature rise decreases.
Scenario D) False. The more evaporation creates the more greenhouse effect. Therefore, temperature rise increases.
Scenario E) True. If reflected radiation increases from Earth, temperature rise of the Earth will decrease. Ice cover increases reflectivity which leads temperature level decrease.
Scenario F) False. If reflected radiation increases from Earth, temperature rise of the Earth will decrease. Ice cover increases reflectivity which leads temperature level decrease.
Answer:
They are both correct.
Explanation:
The density of an object is defined as the ratio of its mass to its volume. This implies that the density of the object is both proportional to the mass and also to the volume of the object. John only mentioned mass which is correct. Linda mentioned the second variable on which density depends which is the volume of the object.
Hence considering the both statements objectively, one can say that they are both correct.
