A community plans to build a facility to convert solar radiation to electrical power. The community requires 1.00 MW of power, a
Aneli [31]

We will find that the effective area that must be used to get the desired power is 3,333.33 m^2

The information we have is:

power needed = 1.00 MW = 1,000,000 watts

Energy of the Sun = 1,000 W/m^2

We know that the system has an efficiency of 30%, then per meter square, the energy converted is:

E = 0.3*1,000 W/m^2 = 300 W/m^2

Now we need to find the area (in meters squared) such that:

A*E  = 1,000,000 watts

A*(300 W/m^2) =  1,000,000 watts

A = (1,000,000 watts)/(300 W/m^2) = 3,333.33 m^2

So the effective area that must be used is A =  3,333.33 m^2

In attempting to pull a 1500 kg car out of a ditch, Al exerts a force of 200 N for 5 s, Bill exerts a force of 500 N for two s,
MArishka [77]

Answer:

Clyde will provide greater impulse

Explanation:

We have given that Al exerts a force of 200 N for 5 sec

We know that impulse is given by, impulse = force ×time = 200×5 =1000 N-s

Bill exerts a force of 500 N for 2 sec

So impulse = 500×2 = 1000 N-s

Now the force exerted by Clyde 300 N for 4 sec

So impulse = 300×4 = 1200 N-s

From above calculation we can see that Clyde provide greater impulse than any other

Two trains are headed towards each other on the same track unbeknownst to the engineers. One departs San Francisco. Its average
aalyn [17]

Answer:

7,166 hrs =430  minutes

Explanation:

Since both train are on the same track, going one towards the other, the relative speed is the addition of both, then the time they need to meet, and consistently crash, is the time that (65mph + 55 mph)=120mph need to travel the total distance of 860 miles, of course in this case one part is traveled by the first train and the rest by the other. Then to find the time we use a three rule

1 h --->120mi

X ---->860mi, then X=(860 mi* 1h)/120 mi = 43/6 hrs= 7,16666 hrs, turning this into minutes need that we notice 1h=60min, then 43/6 hrs *60 min/hrs = 430 minutes.
