Answer:
Gravitational force is given by:
F=G×
d
2
m×M
Distance between two masses is increased s.t. new distance is D= 5 d
New gravitational force F
1
=F
Let on of the mass is changed to m
1
so as to maintain the same gravitational force.
The slope would be 8.92g/cm^3.
<em>D = m/V</em>
<em>m = DV
</em>
The equation for a straight line is
<em>y</em> = m<em>x</em> +b, where m is the slope and b is the y-intercept. We have
<em>m</em> = D<em>V</em> + 0
Thus, a plot of <em>m</em> vs <em>V</em> will give a straight line with a slope of <em>D</em> and a
<em>y</em>-intercept at the origin.
Slope = <em>D</em> = 8.92g/cm^3
The amount of heat needed to vaporize the given amount of water is the product of the amount in grams and the latent heat of vaporization in cal per gram. That is,
H = (540 calories / gram)( 500 grams) = 270,000 cal
Thus, the heat needed is 270, 000 calories. The answer is letter C.
Hey there!
Usually what's taught in school is this.
Solid- Particles packed, little energy.
Liquid- Particles less packed, more energy.
Gas- High energy in particles, less particle restriction, very spread out.
But here's the extra thing,
Plasma- Examples are things like fire and lightning. Very, very, high energy.
Hopefully this helps!
