The fulcrum is the point in any mechanical device where the moment due to weights is zero.
(Weight 1 x distance 1) - (weight 2 x distance 2) = 0
(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0
weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m
= 2.1 Kg
A. they can use damage to property sometimes even bury villages
<span>When frog matures from tadpole to adult, its gills are lost and develops functioning lungs. After maturity, frogs are still able to breathe through their skin---- known as “bimodal breathing,” wherein an animal uses two different systems for bringing in oxygen. These two different breathing systems allow adult frogs to shift between aquatic habitats (which require skin respiration) and land habitats (which are more suited to lung respiration).</span>
Woah where do i start well first earthquakes are movements of tectonic plates under the crust when they slide together they make vibrations wich is what we feel but they happen mostly on fault lines places like San Andreas are on those lines so they feel them most. fault lines are the place where 2 continents meet as they drift and move on liquid magma under them they crash into each other.
