Answer:
1069.38 gallons
Explanation:
Let V₀ = 1.07 × 10³ be the initial volume of the gasoline at temperature θ₁ = 52 °F. Let V₁ be the volume at θ₂ = 97 °F.
V₁ = V₀(1 + βΔθ) β = coefficient of volume expansion for gasoline = 9.6 × 10⁻⁴ °C⁻¹
Δθ = (5/9)(97°F -52°F) °C = 25 °C.
Let V₂ be its final volume when it cools to 52°F in the tank is
V₂ = V₁(1 - βΔθ) = V₀(1 + βΔθ)(1 - βΔθ) = V₀(1 - [βΔθ]²)
= 1.07 × 10³(1 - [9.6 × 10⁻⁴ °C⁻¹ × 25 °C]²)
= 1.07 × 10³(1 - [0.024]²)
= 1.07 × 10³(1 - 0.000576)
= 1.07 × 10³(0.999424)
= 1069.38 gallons
Explanation:
KE = 1/2*m*v^2
mass won't change
but velocity is
A: the force is pushing against the direction of the object, so velocity is decreasing, so KE is decreasing
B: the F net line is pretty much straight up, which means there is no net force pushing to the left, but velocity is still increasing
Why? Because if you use the pythagorean theorem, the hypotenuse is always longer than the legs.
Note: velocity only ever stays the same if there is no net force (or 0 acceleration), so all four of these are either decreasing or increasing
C: there is a net force to the right, so velocity is increasing
D: There is a net force to the right but velocity is to the left, so velocity is decreasing
Hope I got these right
Answer:
No, we should not pay attention to these opinions. (Find the essay below)
Explanation:
Celebrities are people who are prominent or well known because of the work that they do. Actors and sports stars are rightly classified as celebrities because their work affords them a lot of exposure. We see them on television, the internet and social media, and hear about their deeds and accomplishments on the radio.
This group of people always have their opinions about life and other topics of interest which they air when interviewed or when they decide to volunteer the information on their own accord. Most times fans who love them value their opinion so much that they even adjust to them or view it as the standard. For these fans, celebrities are their role models. They tend to copy their hairstyles, modes of dressing, and their opinions! Advertisers key to this fact when they use them to promote their goods.
It is very wrong to hold the opinions and actions of celebrities as the gold standard because they are imperfect and are prone to mistakes. Celebrities are just like any other one of us who have opinions or behave in ways that are sometimes wrong. Copying their every move, action, and opinions would be potentially damaging to us. Their opinions should be taken with a pinch of salt.
It is important that while fans maintain the love they have for their favorite celebrities, they also endeavor to have a mind of their own. Each person should know what works for him or her and live by such. It would be a great mistake to be easily carried away by the opinions of others.
Conclusively, balance is key. Love for celebrities should never cloud an individual's thinking. When this is done, future heartaches that come from adhering to wrong opinions can be avoided.
