If the basalt at the top of the ancient valley below Vulcan's Throne yields a radiometric date (K-Ar) of 15,000 years, and the l
zepelin [54]

Answer:

1.69\times 10^3feet/million year

Step-by-step explanation:

We are given that

Elevation of top of basalt in valley =4100 feet

Elevation of bottom of basalt in valley =2100 feet

Age of top of basalt in valley=15000 years

Age of bottom of basalt in valley=1.2 million years=1.2\times 10^6 years=1200000 years

We have to find the rate of basalt filling in the valley in feet per million yeas

Rate of basalt filling in the valley=\frac{Elevation\;of\;top\;of\;basalt\;in\;valley-elevation\;of\;bottom\;of\;basalt\;in\;valley}{age\;of\;bottom\;of\;basalt\;in\;valley-age\;of\;top\;of\;basalt\;in\;valley}

Rate of basalt filling in the valley=\frac{4100-2100}{1200000-15000}=\frac{2000}{1185000}=1.69\times 10^{-3} feet/year

Rate of basalt filling in the valley=1.69\times 10^{-3}\times 10^{6}=1.69\times 10^3feet/million year

A plane is flying horizontally with speed 315m/s at a height 2770m above the ground, when a package is dropped from the plane.Th
german

Answer:

3) directly above the package.

Step-by-step explanation:

The plane and the package carried by the plane are traveling with the same horizontal speed. When the package is dropped, a new vertical component of velocity is added to the package. The vertical velocity increases because of the acceleration due to gravity. The horizontal speed of the package remains the same. As long as the plane continues to fly at the same speed, the package hits the ground directly below the plane.

Answer: 3) directly above the package.
