What causes melting of material under divergent plate boundaries?

Triss [41]

Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting

A sports car traveling along a straight line increases its speed from 19.8 mi/h to 59.9 mi/h.a. What is the ratio of the final t

Natasha2012 [34]

Answer

given,

initial speed of the car (v₁)= 19.8 mi/h

final speed of the car (v₂)= 59.9 mi/h

a) initial momentum = m v₁

P₁ = 19.8 m

final final momentum = m v₂

P₂ = 59.9 m

ratio = $\dfrac{P_2}{P_1}$

= $\dfrac{59.9 m}{19.8 m}$

ratio of momentum= $\dfrac{P_2}{P_1}=3.025$

b) initial kinetic energy= 1/2 m v₁²

K₁ = 196.02 m

final kinetic energy= 1/2 m v₂²

K₂ = 1794.005 m

ratio = $\dfrac{K_2}{K_1}$

= $\dfrac{1794.005 m}{196.02 m}$

ratio of Kinetic energy= $\dfrac{P_2}{P_1}=9.15$

In a race, a runner traveled 12 meters in 4.0 seconds as she accelerated uniformly from rest. The magnitude of the acceleration

mestny [16]

<span>The runner is moving by uniformly accelerated motion, starting from rest (so, his initial velocity is zero). The law of motion of the runner is
</span> $x(t) = \frac{1}{2} at^2$ <span>
where x(t) is the distance covered after time t, and a is the acceleration of the runner. By re-arranging the formula, we get
</span> $a= \frac{2S}{t^2}$ <span>
We know the runner has covered a distance of S=12m in t=4.0 s, and if we plug these numbers into the equation, we find the acceleration of the runner:
</span> $a= \frac{2S}{t^2} = \frac{(2*12m)}{(4s)^2} =1.5 m/s^2$ <span>
</span>

How would the moon appear from Earth if the moon did not rotate?

andrey2020 [161]

It would mean that only one side of earth would be light and the other dark all the time also we would only see the sun on one side and on the other we see the moon

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.
