As an object sinks in a fluid, the buoyant force ____.
german
I think the correct answer from the choices listed above is option C. As an object sinks in a fluid, the buoyant force increases before it is submerged and as the object is submerged the buoyant force stays the same. This can be explained by Archimedes principle.<span />

If ∆H = + VE , THEN WHAT REACTION IT IS<br>1) exothermic<br>2) endothermic​
podryga [215]

Answer:

endothermic

Explanation:

An endothermic is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Why is the sum of forces/net force less than the applied force? Think about the direction of the forces in your answer
Reil [10]

Answer:

he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem

Explanation:

When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.

Let's carry out an example with two forces, F1 and F2 of equal magnitudes

if they are in the same direction

           F_total = F₁ + F₂ = 2 F

if they are at 90º

          F_total = \sqrt{F_1^2 + F_2^2}= \sqrt{2}  \ F

if they are at 180º

          F_total = F₁ -F₂ = 0
