Work is defined as the force times the distance which is mathematically expressed W = Fxd. The given force is 5x10^4 and the distance is 10000 m (the distance is converted as meter because Nm = J) the work done by the wind is W = 5x10^4 N (10000) = 500 x 10^6 Joules. I hope it answered your question
Pseudoscience
Pseudoscience is made of up statements, beliefs or practices that claim to be scientific and factual but are not based in the scientific method.
Answer:
I'm pretty sure it's false
Explanation:
.
B. Barometer is used to measure atmospheric pressure.
Answer:
4776.98 N is the minimum force to start the rise.
Explanation:
We can use the first Newton's law to find the minimum force to move the block.
So we will have:
Where:
- F is the force
- W(x) is the weight of the block in the x direction, W = mg*sin(15)
- F(f) is the static friction force (F(f) = μN), μ is the static friction coefficient 0.4.
Therefore 4776.98 N is the minimum force to move the block.
