1.Why is it important to accurately predict possible formation and path of a hurricane?

stellarik [79]

1. By predicting the path of hurricanes, it is possible to warn people in its prospective path in advance. This way lives can be saved. In addition economic cost. associated with its destruction, can be minimized by bracing in advance for the storm along its path.

2. When the sea temperatures increase, there is increased vaporization of water into the atmosphere. This causes a transfer of heat into the atmosphere from the hydrosphere. This causes a drop of pressure in the local region that is one ingredient associated with the beginning of a hurricane.

3. The more the humidity, it means the more the heat transfer to the atmosphere through condensation. This reduces the pressure proportionally with the amount of humidity. This low pressure is an ingredient for hurricanes. In addition, the higher the humidity the larger the clouds and the larger the thunderstorms and precipitation associated with the hurricane

4. Winds drive hurricanes and determines their vicious force. In the formation of the hurricane, low winds are required to allow the formation of the funnel at the front betwen the cold and warm air masses. Winds blowing in congruence with the hurricane after then make it stronger while those that blow against it weaken it.

5. The answer is; YES, I would expect a hurricane. This is because at 12 0 N and 45 0 W are the open oceans of the Pacific. The average sea temperaturs in summer is between 15 0 and 20 0. At 27.5 0, this increases the humidity at the local region and therefore the tranfer of heat to the atmsphere. The light breeze gives the stability required for the air convection currents to occur forming a funnel front between the air masses.

how does a particle differ from its anti-particle? it has opposite mass. it has opposite charge. its wave-function is the opposi

FromTheMoon [43]

An antiparticle is a subatomic particle that, by definition, has the same mass as its normal particle counterpart but the opposite magnetic moment and electric charge. An electron's antiparticle, for instance, is the positron.

The mass of an antiparticle is equal to that of the particle version, but it has the opposite charge. Antiparticles have opposite charges, baryon numbers, lepton numbers, and strangeness. A subatomic particle known as an antiparticle has the same mass as a particle of regular matter but the opposite electric charge and magnetic moment. Thus, the positron (a positively charged electron) is the opposite of the negatively charged electron.

Un libro del peso di 12 N è in equilibrio su un tavolo. Sapendo che il coefficiente di attrito statico vale 0,5, la forza di att

Tanzania [10]

Answer:

60

Explanation:

Translation -

A book weighing 12 N is balanced on a table. Knowing that the static friction coefficient is 0.5, how much is the friction force worth?

Friction force is

f = u * n

f = 0.5 * 12N

f = 60

A solid block of metal is at its melting temperature. it takes 24j to melt 6kg of a metal. what is the latent heat of fusion of

Marina86 [1]

The Latent heat of fusion is also known as the Enthalpy of Fusion. It is a kind pf change in enthalpy.

<h3>Brief explanation of Latent Heat of Fusion? </h3>

The latent heat of fusion, is the change in enthalpy that takes place when energy, typically heat, is provided to a specific quantity of a substance to causes it to change from a solid state to a liquid state at a constant pressure.

For instance, 1 kilogram of ice melts at 0 °C at a variety of pressures, absorbing 333.55 kJ of energy without causing a change in temperature.

The heat of solidification, which occurs when a substance changes from a liquid to a solid, is equal and opposing.

This energy includes the contribution necessary to displace its surroundings against ambient pressure in order to accommodate any corresponding change in volume.

The melting point or the freezing point, depending on the situation, is the temperature at which the phase transition takes place. Conventionally, unless otherwise stated, the pressure is taken to be 1 atm (101.325 kPa).

<h3>Calculation</h3>

The formula of latent heat of fusion is L= q/m

Here q is the heat provided and m is the mass of the object.

So, L = 24j/6kg

L= 4j/kg

So, the latent heat of fusion is 4 j/kg
