The geosphere interacts with the hydrosphere when water causes rock to erode. The atmosphere provides the geosphere with heat and energy for erosion, and the geosphere reflects the sun's energy back into the atmosphere.
V = at + V0
where v0 is the initial speed, a is the acceleration and t is the time.
So:
v = 5m/s^2*5s + 25m/s = 50 m/s
Answer:
Answer:
71.6°
Explanation:
According to the diagram
ED = 6 feet
DA = EB = 3 feet
AC = 15 feet
AB = ED = 6 feet
BC = AC - AB = 15 - 6 = 9 feet
Let the angle is θ from the horizontal
By the triangle EBC
tanθ = BC / EB = 9 / 3
tanθ = 3
θ = 71.6°
Thus, the angle from the horizontal is 71.6°.
Explanation:
Answer:
How does each sum relate to the energy of the absorbed photon? the total energy of each set of emitted photons is equal to the energy of the absorbed photon.
Explanation:
The speed of the wave in water is 833.33 m/s
The given parameters;
- depth of the wrecked ship, d = 1000 m
- frequency of the wave transmitted, f = 50 kHz
- time of motion of the echo, t = 2.4 s
The speed of the wave in water is calculated by applying echo equation as shown below;
Thus, the speed of the wave in water is 833.33 m/s
