Answer:This is an explanation
for 150 km its all ik i tried hard ty
Explanation:The car covers 150 km in 3 hours or 3*60 = 180 minutes.
So in 12 min the car will cover (12/180)*150 = 10 km.
In a spectrograph, black lines can be seen going through the array of colors. The pattern of these lines indicate the composition of the star.
Different elements block different parts of the spectrum, resulting in black lines.
The correct answer would be false. The less internal heat a jovian planet emits the lesser it stirs up its clouds making the atmosphere hotter. All of the four Jovian planets have unique atmospheres. They have more or less the same structures but they differ in their average temperature. As the distance of the planet is closer to the sun the atmosphere would be cooler. These planets are Jupiter, Saturn, Uranus and Neptune. They do not have a solid structure instead they are primarily composed of helium and hydrogen which makes them gas giants or ice planets. They are larger in size than the remaining planets in the solar system.
The pyrite will be bigger, because its density is much lower.
I <em>do</em> know that the gold's volume will be 2.5906 (With a bunch more numbers after it)
50 divided by 19.3 = 2.5906
Answer:
(a) Both the charges are positive or negative.
(b) Teh value of each charge is 1.53 x 10^-5 C.
Explanation:
Spring constant, K = 340 N/m
Natural length, L = 0.4 m
stretch, y = 0.033 m
(a) Let the charge on each sphere is q and they repel each other so the nature of charge of either sphere may be both positive or both negative.
(b) The electrostatic force is balanced by the spring force.
