Option (C)

Explanation:

The magma in the hot-spot region are basaltic, they can move fast because of their low viscosity. Whereas, the magma present in the subduction zone are rhyolitic, and moves slowly due to its high viscosity. Viscosity of a magma is directly proportional to its silica content.

This is the difference between the volcanoes over a hot-spot region and over subduction zone.

Answer: Thus, the correct answer is option (C).

C. Volcanoes above subduction zones have lava that is not basaltic.

Two 110 kg bumper cars are moving toward each other in opposite directions. Car A is moving at 8 m/s and Car Z at –10 m/s when t

salantis [7]

Explanation:

Mass of bumper cars, $m_1=m_2=110\ kg$

Initial speed of car A, $u_1=8\ m/s$

Initial speed of car Z, $u_2=-10\ m/s$

Final speed of car A after the collision, $v_1=-10\ m/s$

We need to find the velocity of car Z after the collision. Let it is equal to $v_2$ . Using the conservation of momentum as :

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

$110\times 8+110\times (-10)=110\times (-10)+110v_2$

$v_2=\dfrac{-1320}{110}\ m/s$

$v_2=-12\ m/s$

So, the velocity of car Z after the collision is (-12 m/s). Hence, this is the required solution.

A dog of mass 4 kg runs up a hill of height 8 m. How much gravitational potential energy does the dog gain?

Genrish500 [490]

A. 314 because when you use the formula for the GPE ; GPE=MGH or means mass times gravity time height (4x8x9.8) and thats equivalent to 313.6 which rounds up to 314. Hope it helps
