The gravitational potential energy of the object is 100 J.

Gravitational potential energy stored in an object is the work done in raising the object to a height <em>h</em> against the gravitational force acting on it.

The gravitational force acting on a body is its weight mg, where m is its mass and g, the acceleration due to gravity.

Work done by a force is equal to the product of the force and the displacement made by the point of application of the force.

$GPE = mgh$

The weight of the object is given as 20 J and it is raised to a height of 5 m.

$GPE =(mg)*h = (20 N)*(5m)=100 J$

The gravitational potential energy of the object is 100 J.

The peak wavelength of light coming from a giant red star is 660 nm. Calculate the approximate surface temperature of this star

laiz [17]

Answer:

The value is $T =260.33 \ F$

Explanation:

From the question we are told that

The the peak wavelength is $\lambda_p = 660 nm = 660 *10^{-9} \ m$

Generally according to the Wien's displacement law

$\lambda_p * T = 2.898*10^{-3} \ m \cdot K$

Here T is the approximate surface temperature of this star in K so

$660*10^{-9} * T = 2.898*10^{-3} \ m \cdot K$

=> $T = 4091 \ K$

Converting to Fahrenheit ,

$T = [400 - 273.15 ] * \frac{9}{5} + 32$

=> $T =260.33 \ F$

How does the surface tension of water compared with the surface tension of most other liquids?

Anuta_ua [19.1K]

Surface tension is the direct measure of the cohesive forces between liquid molecules that allows them to form "film", making it more difficult to move an object through the liquid surface. Compared to other known liqiuds, the surface tension of water is much greater.

You would like a pendulum that swings back and forth once every 2 seconds, but the one you have swings once every 1.9 seconds. W

patriot [66]

Your pendulum does a complete swing in 1.9 seconds. You want to SLOW IT DOWN so it takes 2.0 seconds.

Longer pendulums swing slower.

You need to <em>make your pendulum slightly longer</em>.

If your pendulum is hanging by a thread or a thin string, then its speed doesn't depend at all on the weight at the bottom. You can add weight or cut some off, and it won't change the speed a bit.

eimsori [14]

Use the formula M=D×V:

M=10 g/cm³ * 5 cm³ = 50 g

which is more than 40 grams, so the container cannot hold the chain.
