Radiant heat transfer is proportional to the 4-th power of absolute temperature.
Therefore if the temperature is quadrupled, the radiant heat energy will increase by a factor of
4⁴ = 256

Answer: 256

Calculate the magnitude of the acceleration of Io due to the gravitational force exerted by Jupiter. [Show all work, including t
galina1969 [7]

The magnitude of the acceleration due to the gravitational force exerted by Jupiter is 25.91 m/s².

<h3>What is acceleration due to gravity?</h3>
  • This is the acceleration of a body under a free fall due to influence of gravity.

The magnitude of the acceleration due to the gravitational force exerted by Jupiter is calculated as follows;

F = mg = \frac{GmM}{R^2} \\\\g = \frac{GM}{R^2}

where;

  • M is mass of Jupiter
  • R is the radius of Jupiter
  • G is universal constant

g = \frac{6.67 \times 10^{-11} \times 1.8986 \times 10^{27}}{(69,911 \times 10^3)^2} \\\\g = 25.91 \ m/s^2

Thus, the magnitude of the acceleration due to the gravitational force exerted by Jupiter is 25.91 m/s².

Why do smaller endotherms require more energy per unit of mass than larger endotherms?
Naily [24]
They expend more oxygen. Littler endotherms lose warmth to the earth proportionately speedier than huge endotherms: less warm mass, protecting layers in littler creatures are less successful by dint of being more slender, and more prominent surface region to volume proportion implies snappier radiation of warmth

The distance between two objects is increased by three times the oringinal distance. How will this change the force of attractio
tigry1 [53]
<span>The distance between two objects is increased by three times the oringinal distance.  Since they were already separated by one time the original distance,
the additional three times the oringinal distance now puts them four times the original distance apart.

Whether we're talking about the gravitational forces of attraction or
the electrical forces of attraction, either one is inversely proportional
to the square of the distance between the objects. 

So changing the distance to four times the original distance causes
the forces to become 1/4</span>² as strong as they were originally. 

The forces become 1/16 of their original magnitude.<span>

a ball is dropped from rest at a height of 89m above the ground. (a)what is it's speed just before it hits the ground? (b) how l
kykrilka [37]

Answer:

(a) 41.75m/s

(b) 4.26s

Explanation:

Let:

 Distance, D = 89m

 Gravity, g = 9.8 m/s^{2}

Initial Velocity, u = 0m/s

Final Velocity, v = ?

Time Taken, t = ?

With the distance formula, which is

D = ut + \frac{1}{2} gt^2

and by substituting what we already know, we have:

89 = \frac{1}{2}×9.8×t^{2}

With the equation above, we can solve for t:

t=\sqrt{\frac{89(2)}{9.8}} \\t=\sqrt{\frac{178}{9.8} } \\t=\sqrt{18.16} \\t=4.26 seconds

Now that we have solved t, we can use the following velocity formula to solve for v:

v = u + at, where a is also equals to g, so we have

v = u + gt

By substituting u = 0, g = 9.8, and t = 4.26,

We have:

v = 0 + 9.8(4.26)\\v = 41.75m/s
