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:
Boiling water
Explanation:
Boiling water because it has the most rapid movement.
Your answer is it is True. Please no mean comments I'm new to brainly
Answer:
1260 Nm
Explanation:
As one end of the lever makes contact at the point right below the dumpster center of mass and has a distance of 0.3 m to the lever pivot point, plus the fact that the level is also approximately horizontal, we can safely assume that the dumpster gravity is directly perpendicular to the level.
This would make the torque caused by the dumpster gravity on the level is
T = LF = 4200*0.3 = 1260 Nm
To develop this problem it is necessary to apply the concept related to the speed of sound waves in fluids.
By definition we know that the speed would be given by

Bulk modulus
Density of air
From the expression shown above we can realize that the speed of sound is <em>inversely proportional</em> to the fluid in which it is found, in this case the air. When the density increases, the speed of sound decreases and vice versa.
According to the statement then, if the density of the air decreases due to an increase in temperature, we can conclude that the speed of sound increases when the temperature increases. <u>They are directly proportional.</u>
