Earth’s crust continuously melts and solidifies in the upper mantle. Why does oceanic crust solidify faster than continental cru
Softa [21]

The oceanic crust solidifies faster than the continental crust. Because when magma comes into contact with ocean water it cools faster than when it reaches continental rock. Option C is correct.

<h3>What is the crust?</h3>

The outermost layer of a terrestrial planet is referred to as its "crust."

In the upper mantle, the Earth's crust is constantly melting and solidifying. Compared to magma beneath the continental crust, the oceanic crust has a lower temperature.

Magma cools more quickly when it comes into touch with ocean water than when it hits continental rock. causes the continental crust to solidify more slowly than the oceanic crust.

Hence option C is correct.

What happens to the velocity of an object when balanced force acts on it?
Pani-rosa [81]
When the entire group of forces acting on an object is balanced,
the individual forces all add up to zero, and the effect on the object
is the same as it would be if there were no force at all acting on it.

No force on it means no acceleration ... no change in speed or
direction of motion.

No change in speed or direction of motion means constant velocity.

Find equailent resistance​
vovikov84 [41]

Answer:

0.71ohms

Explanation:

AC and CB are in series hence the total resistance is 3+2=5ohms

AD and DB are in series hence the total resistance is 3+2=5ohms

These resistances are parallel to resistance AB

Let the equivalent resistance be R.

For resistances in parallel

Hence the total resistances are:

5//1//5

1/R =1/5 + 1/1 +1/5 = 1+5+1 /5 = 7/5

Hence the total resistance is R= 1/ 7/5 = 1×5/7= 5/7=0.71ohms

For the following types radio waves infared radiation visible light ultraviolet radiation gamma radiation of electromagnetic rad
ddd [48]

Answer: Option 5.

Decreases increases increases.

Explanation:

Electromagnetic spectrum refers to differences in frequencies, wavelengths and photon energies of electromagnetic radiation.

From the top of the list to the bottom i.e from radio waves, infrared waves, visible lights, ultraviolet radiation, gamma radiation, wavelengths decreases, the frequency increases as the photon energy increases.

The electromagnetic radiations : radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays have high-frequency and short wavelengths. Their wavelengths decrease. The photon energy is directly proportional to wave frequency.
