Answer:
The transformation went from a gas to a solid which is a Deposition
Explanation:
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
Answer: (B) They can be penetrated only with longer wavelengths such as radio and infrared.
Explanation:
A dark nebula is a type of interstellar cloud with such a high density that it "hides" the light of the background stars.
It should be noted that these nebulae are composed mostly of hydrogen (the star's primary fuel), and the absence of light (in the visible range of the electromagnetic spectrum) is caused by the interstellar solid dust that constitutes the cloud, which is why they are also called absorption nebulae.
However, <u>if powerful telescopes that detect at long wavelengths, such as infrared and X-rays, it is possible to observe through these nebulae and even observe the existence of young stars.</u>
If the car is going at constant speed than the velocity isnt changing, only the direction of velocity.
Answer:
4 N
Explanation:
Electrostatic force is directly related to the charge of each object hence when the charge is doubled in only one of the objects, the force also double. If it's doubles on both objects, the force becomes four times. In this case, it's doubled on one object hence 2*2= 4 N
