Answer:
144 ft
Explanation:
h(t) = -16t² + 64t + 80
The maximum height is at the vertex. We can find the vertex of a parabola using -b / (2a):
t = -64 / (2×-16)
t = 2
The vertex is at 2 seconds. The height of the stone at this time is:
h(2) = -16(2)² + 64(2) + 80
h(2) = 144
The maximum height is 144 feet.
Answer:
Weight measurement at poles will be slightly more than at equator.
Explanation:
Firstly earth bulges at equator. This makes the body far from earth center at equator than poles. Secondly, the surface centrifugal forces of earth due to rotation also plays vital role in disturbing the gravity value. The centrifugal forces cancel the effect of gravity more at equator than at poles.These factors combine to create difference of about 0.5% in gravity values at pole and equator.
gravity at pole=9.832 m/s^2
gravity at equator=9.780 m/s^2
Answer:
x = 600 Km
Explanation:
given,
speed of transverse wave = 4.05 Km/s
speed of longitudinal wave = 7.695 Km/s
difference of the time of arrival of wave = 69.9 s
now,
t₂ - t₁ = 69.9 s
let x be the distance
x = 597.645 Km
x = 600 Km
distance of recorder from the site is 600 Km approximately.
