That depends on a few things that you haven't told us about the setup.
So I'm going to assume one of them, and then give you the answer
in terms of another one:
-- Assume a Class-I lever . . . the fulcrum is between the load and the effort.
-- Then the effort needed to lift the load is
(the weight of the load) x (13 / the distance between the fulcrum and the effort)
Answer:
Length = 155.6 m
Explanation:
given data
mass = 700 kg
total resistance = 4300 N
tension = 12000 N
speed = 40 m/s
solution
we get here equation for glider in the back and front
for the glider in the back
T - 2400 = 700 a ...........1
for the glider in front
12000 - T - 2400 = 700a .............2
now we add both these equations
12000 - 4800 = 1400 a .............3
a = 5.14 m/s²
and
now we use equation of motion
v² - u² = 2 a S .............4
40² = 2 × 5.14 × S
so
Length = 155.6 m
You have been given the storm's velocity.
Answer:
Exothermic Reaction
Explanation:
<u>ENDOTHERMIC REACTION</u>: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.
The value of enthalpy change ΔH is positive in such reactions showing intake of energy.
<u>EXOTHERMIC REACTION</u>: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.
The value of enthalpy change ΔH is negative in such reactions showing the release of energy.
Since, the value of ΔH = -125 KJ, is negative for the given reaction.
Therefore, it would be considered as <u>Exothermic Reaction.</u>
Answer:
velocity of the object
Explanation:
For an object moving at a constant acceleration, we would expect to see a position graph with a curved shape and a velocity graph with a straight shape.
