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

Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.
Volcanic eruption would change the surface the quickest
