The reaction time of Boris is t(r), so before that, Boris will not have jumped. Thus, H(b)(t) = 0
The vertical displacement will simply be
D(t) = H(a)(t)
I'd guess at valve B. more information about the interesting question would help.
1. First blank is A. Conductors
Second blank is D. Insulators
2. C. Heat
Answer:
<em>Billow clouds provide a visible signal to aviation interests of potentially dangerous turbulent sky since they indicate instability in air currents.</em>
Explanation:
Billow clouds are created in regions that are not stable in a meteorological sense. They are frequently present in places with air flows, and have marked vertical shear and weak thermal separation and inversion (colder air stays on top of warmer air). Billow clouds are formed when two air currents of varying speeds meet in the atmosphere. They create a stunning sight that looks like rolling ocean waves. Billow clouds have a very short life span of minutes but they provide a visible signal to aviation interests of potentially dangerous turbulent sky since they indicate instability in air currents, which although may not affect us on the ground but is a concern to aircraft pilots. The turbulence due to the Billow wave is the only logical explanation for the loss of 500 m in altitude of the plane.
Answer:
10 gram gold is added
Explanation:
given data
pure gold = (24/24)
added = 15 grams
gold = 14 K ( 14/24)
gold = 18 K ( 18/24)
to find out
How much pure gold added
solution
we know here that when we add gold to get 20 K gold or 22K
so we added here 15 gram 14 K
we consider here m is pure gold added
so by composition here
we get
15 (14K) + m ( 24 K) = ( 15 + m ) (18) ...................1
solve it and find m
m = 10
so 10 gram gold is added
