Answer:
6.34×10⁹ seconds
Explanation:
Applying,
V = d/t............. Equation 1
Where V = speed plate, d = distance covered by the plate, t = time it takes the plate to travel
make t the subject of the equation
t = d/V............ Equation 2
From the question,
Given: d = 5 cm/yr = (5×3.154×10⁻⁹) = 1.577×10⁻⁸ m/s, d = 100 meter
Substitute these values into equation 2
t = 100/1.577×10⁻⁸
t = 6.34×10⁹ seconds
Hence the time it takes the the plate to travel is 6.34×10⁹ seconds

Explanation:
Solar panels are a renewable resource because they take energy from the sun.
Answer:
-11 m
Explanation:
Given:
v₀ = 12.5 m/s
v = -13.7 m/s
t = 18.3 s
Find: Δx
Δx = ½ (v + v₀) t
Δx = ½ (-13.7 m/s + 12.5 m/s) (18.3 s)
Δx = -11 m
