Turn into stone. this will cause erosion for magma to turn to stone
Answer:
677 m
Explanation:
Using the definition of the sine of an angle, we can write
sin 14.1 = (height of mountain) / (slope length of mountain)
sin 14.1 = H / (2780 m) ---> H = (2780 m) x sin 14.1
= 677 m
Answer:
a = -04978 m / s²
Explanation:
For this exercise we can use the kinematics equations, as the initial speed, distance and time indicate, we can use
x = x₀ + v₀ t + 1 /2 a t²
½ a t² = x-x₀ - v₀ t
a = (x-x₀ - v₀ t) 2 / t²
let's reduce the magnitudes to the SI system
x₀ = 1000 mm = 1 m
x = 5000mm = 5m
let's calculate
a = (5 - 1 - 15 60) 2/60²
a = -04978 m / s²
negative sign indicates that braking is related
<h3><u>Answer;</u></h3>
= 480 Joules
<h3><u>Explanation;</u></h3>
We use the formula, Q - W = ΔU
Where, Q = Heat transferred to the system
W = Work done by the system
ΔU = Change of internal energy.
As per the question, Q = 658 J
ΔU = 178 J
Thus, W = Q - ΔU = (658 - 178) J = 480 J.
The energy used to do work by the system is 480 J.
