Answer:
When put into steam
Explanation:
When a certain amount of steam at boiling temperature condenses (turning into water), the amount of heat released is
where in this case
m = 25.0 g = 0.025 kg is the mass of steam at 100.0°C
is the latent heat of vaporization of water
So,
Instead, the amount of heat released when the water at 100.0°C is cooled down to 34.0°C is given by
where
m = 25.0 g = 0.025 kg is the mass of water
is the specific heat of water
is the change in temperature
Therefore,
Since 
, we can say that your hand will burn more in the first case.
Due to the principle of conservation of energy, the work done by the engine to move the scooter converts into kinetic energy of the scooter:
where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
Answer: The second option.When
the current flows up the wire, the magnetic field flows out on the left
side of the wire and in on the right side of the wire.Explanation:
The first figure that I copy here with is the figure corresponding to this question.
The thumb is pointing upward.
The rule is that the thumb aims to the direction of the flow of current and the other fingers give the field lines.
The second figure that I attach is a free image from internet and it shows the direction of both the current and the fiedl lines.
So, the conclusion is that
the current goes upward the wire and the field lines go out of the paper (screen) for the points to the left of the wire and in on the right side of the wire.
A cold<span> front </span>occurs when a cold air mass advances into a region occupied by a warm air mass<span>. If the boundary between the </span>cold<span> and </span>warm air masses<span> doesn't move, it is called a stationary front. This is due to the (usually) higher humidity in the </span>air<span> of </span>warm<span> fronts compared to that of </span>cold<span> fronts.
Hope this helps</span>
Speed= freq x wavelength
if freq is doubled the wavelength will halve for constant speed
