Answer:
F = m g sin theta force accelerating block

a = 9.8 sin 24 = 3.99 m/sec^2
D. Advances in technology were needed to gather more evidence.
Explanation:
New technologies had to be developed to ascertain Wegener's claims.
The major flaw in Wegener's postulate was that the moving continents lacked a mechanism to drive them into motion.
His theory needed more scientific backing also.
- A major leap was made when new technologies used during the second world war was deployed to investigate the ocean floor.
- Sequences of magnetic anomalies were unraveled using equipment developed during the second world war
- This gave further proof to the idea of continental drift and it expanded the theory into a more broader and inclusive theory of plate tectonics.
