We know that;
power=W/t
15000Watts=1800000J/t
t=1800000J/15000Watts
t=120s
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
It is incorrect, because the identity of the original product has changed. Ca3(OH)2 does not exist! It is no longer calcium hydroxide. To balance an equation, you must manipulate the coefficients, a.k.a. the big numbers that go before reactants or products. Subscripts, the little numbers inside the reactants or products, cannot be changed without completely changing the substance.
<span>The answer 0.00140 kiloliters
</span><span>ecause one litre=100 centiliters, and one kilolitre=one litre which means that one kilolitre =100000 centiliters So 140 centiliters are 140 divided by 100000 kiloliters=0.00140 kiloliters</span>
