<span>If a lever has a constant force applied at 90∘ to the lever arm at a fixed distance from the pivot point (point of rotation), the torque on the lever is given by Torque = force (at 90∘ to lever arm) × distance to pivot point
Force should be perpendicular to the lever arm
Therefore; you would do 15N X 2.0 m = 30 Nm or 30Joules</span>
Answer: Esta tendencia es tan regular que el poder de combinación, o valencia, de un elemento se definió una vez como el número de átomos de hidrógeno unidos al elemento en su hidruro. El hidrógeno es el único elemento que forma compuestos en los que los electrones de valencia están en la capa n = 1.
Explanation:
¡Espero que esto ayude!
m/s² aka meter per second squared.
acceleration = change in velocity/time
= distance/time
--
time
= m/s
--
s
=m/s^2
I also think it’s B but not quite sure
The answer is <span>Silicon, it also forms 4 bonds. Usually elements in the same group or vertical column in the periodic table all have similar chemical bonding properties. </span><span>It is just below carbon, so it has more similarities of properties with carbon. </span>
