Quando aquecemos água em nossas casas, ao nível do mar, utilizando um recipiente aberto, sua temperatura nunca ultrapassa os 100

°C. Isso ocorre porque:
a) ao atingir essa temperatura, a agua perde sua capacidade de absorver calor.
b) ao atingir essa temperatura, a agua passa a perder exatamente a mesma quantidade de calor que esta recebendo, mantendo assim a temperatura constante.
c) as mudanças de fase ocorrem à temperatura constante.
d) ao atingir essa temperatura, a agua começa a expelir o oxigenio e outros gases nela dissolvidos.
e) as mudanças de fases de agua sempre ocorrem em 100 graus Celsius

A wrecking ball is suspended from a 7.0-m-long cable that makes a 25 ? angle with the vertical. the ball is released and swings
Neko [114]
The height of the ball when lifted is given by 7sin(25)=2.96
the gravitational energy is mgh, the kinetic is (1/2)mv².  We can set these equal since the pendulum doesn't lose much energy
mgh = (1/2)mv²
we can divide by m (since we don't have it anyways)
gh = v²/2
v=√(gh/2) = √(9.81*2.96/2)=3.8m/s.
Not exactly one of your choices, but the right one none the less

Eq-48 when operating your vessel with a vhf radio, what channel must you monitor?
77julia77 [94]

VHF Channel 16 must always be monitored. It is the calling and distress channel. This is where the operator might hear a MAYDAY call. This is also where the operator can issue a MAYDAY. Improper misuse of the channel can result to penalties.
