Answer:
Explanation:
To solve this problem we use the Hooke's Law:
(1)
F is the Force needed to expand or compress the spring by a distance Δx.
The spring stretches 0.2cm per Newton, in other words:
1N=k*0.2cm ⇒ k=1N/0.2cm=5N/cm
The force applied is due to the weight
We replace in (1):
We solve the equation for m:
Answer:
Explanation:
Vectorially speaking, torque is the cross product between force and distance from fulcrum. Its magnitude is equal to the following expression:
Let assume that force is perpendicular to the distance from the fulcrum. So, the torque needed to turn the bolt is:
Answer:
rotation
Explanation:
The spinning of the Earth on its axis from west to east is called rotation. Effects of the Earth’s rotation are: The rotation of the Earth causes the day and the night. … Due to rotation, winds and the ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. doggo knows ctrl+c, ctrl+v.
