The temperature that the aluminum will have a resistivity that is three times the resistivity copper has at room temperature is 227°C.

<h3>How to calculate the temperature?</h3>

It should be noted that the temperature of resistivity is given as:

p(t) = p(20°C) (1 + (t - 20°C)

The resistivity at room temperature is illustrated as:

pCu(20°C) = 1.68 × 10^-8

pAl(20°C) = 2.65 × 10^-8

Therefore, the equation will be:

3 × 1.68 × 10^-8 = 2.65 × 10^-8(1 + 0.00435(t - 20°C)

0.902 = 0.00435(t - 20°C)

t = 20 + 207

t = 227°C

Therefore, the temperature is 227°C.

a=5 m/s²

t=20 s. Therefore;

Vf=14+(5*20)

Vf=114 m/s.

The average intensity of sunlight at the top of the earth's atmosphere in 1390 w/m2. what is the maximum energy that a 34-m x 46
slavikrds [6]
Panel surface area =34m×46m=1,564m^2
total power =1564m^2×1390w/m^2
=2173960watts
now you must calculate total energy.
Energy = power×Time
However time must be in seconds so we multiply 2hrs×60min×60s=7200seconds
7200s×2173960w =15,652,512,000 joules of energy

Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)

Power output of an engine is with work (w=60,000) during 60 s Calculate the power of this work?*
igomit [66]

Answer:

<em>The power output of the engine is 1,000 Watt</em>

Explanation:

<u>Mechanical Power </u>

Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.

The power can be calculated as:

\displaystyle P=\frac {W}{t}

Where W is the work and t is the time.

The engine does a work of W=60,000 J during t=60 s. Calculate the power:

\displaystyle P=\frac {60,000}{60}

P = 1,000 Watt

The power output of the engine is 1,000 Watt
