A small child gives a plastic frog a big push at the bottom of a slippery 2.0 meter long, 1.0 meter high ramp, starting it with
lesya692 [45]
First, let's find the angle of inclination using the tangent function.

sin θ = opposite/hypotenuse = 1 m/2 m
θ = 30°

Assuming the ramp is frictionless, the force balance is:
F = mgsinθ = ma
Cancelling out m,
a = gsinθ = (9.81 m/s²)(sin 30°) = 4.905 m/s²

Using the equation for rectilinear motion at constant acceleration,
x = v₀t + 0.5at²
2 m = (6 m/s)(t) + 0.5(4.905 m/s²)(t²)
Solving for tm
t = 0.297 seconds

Using the equation for acceleration:
a = (v - v₀)/t
4.905 m/s² = (v - 6 m/s)/0.297 s
Solving for v,
v = 7.46 m/s

Answer:

Location B, because cracks between plates are filled with molten rocks which solidify

Explanation:

Location B because, as the tectonic plates move away under the sea, inside the sea are cracks of the ocean floor that releases molten rocks, or a type of liquid that hardens when interacting with liquid (thats from the mantle).

State one way by which Carbon Dioxide increases in the atmosphere
weeeeeb [17]

Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
