Answer:

1. 1816

2. In order to make a weather map, what process was followed? They had to manually plot out the points of equal atmospheric pressure on an Isobar. Then, plot the rest of the information intended for that map.

3.  Early weather maps could only be surface charts. There was no way of knowing what was happening higher in the troposphere so a complete picture of the atmosphere was impossible.

4. The weather maps are the most valuable tool to a meteorologist because it helps with the weather forecast. Without the weather maps it would be hard to predict what the weather would be. They help summarize what is going on in the atmosphere.

5. The information is then electronically sent to Washington, DC where it is analyzed.

Hope it helps! <3

Explain how machines can be useful if the output is always less than the input work
Anni [7]

Because: Some of the work done by the machine is used to overcome the friction created by the use of the machine. ... Work output can never be greater than work input. Machines allow force to be applied over a greater distance, which means that less force will be needed for the same amount of work.

How much electrical energy is used by a 400 W toaster that is operating for 5 minutes?
Shkiper50 [21]

The electrical energy consumed by a toaster is 0.033 Kwh.

<u>Explanation</u>:

The power utilized by the toaster is 400 W.

\text { The power utilized by the toaster is } 400 \mathrm{W} \text { in kilo-watts is } \frac{400}{1000}=0.4 \mathrm{Kw}

The toaster is operated for 5 Minutes.

\text { The toaster is operated for } 5 \text { Minutes in hours is } \frac{5}{60}=0.083 \text { hours. (One minute is } 60 \text { seconds) }

We know that,

\text {power}=\frac{\text {energy}}{\text {time}}

Substitute the values in the above formula to obtain electrical energy,

0.4=\frac{\text { energy }}{0.083}

Electrical energy = 0.4 × 0.083

Electrical energy is 0.033 Kwh.
