the relatively thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.

ivolga24 [154]

Answer: Mars has lower gravity and lower magma buoyancy

Explanation: The gravity in mars is low. Low gravity affect the occurrence of volcanic eruptions. The buoyancy of the magma in Mars is lower and the depth of the magma chamber deeper (Buoyancy is the difference in density between the surrounding crust and the magma ascending for eruption). Olympus Mons which is larger and wider than mount Everest was formed as a result of overcoming of the low gravity and buoyancy by the magma to release enormous volume of magma to the surface.

Another reason why the volcanoes on Mars are so large is because the crust on Mars is static unlike Earth.

Two friends, Joe and Sam, go to the gym together to strength train. They decide to start off with an exercise called flat bench

astra-53 [7]

Answer:

216.31 (the work done by gravity is -216.31) positive for going up.

Explanation:

We look at this question first by getting the right equation for <em>work</em>.

Which should be... W = F x D.

From this, we can do everything, we need the Force (F) first - the question tells us that Joe is lying on his back and moves his arms upward to raise the barbell. This means that he is countering the force of graving on the object.

What is the formula for the force of gravity on an object near the earth?

Right here --- $F_{grav}$ = mg

m = the mass and...

g = the acceleration due to gravity which is <em>9.81 m/s2</em>

Before we plug things in though, we need to convert everything to SI units,

the weight is in kg - so we're good to go there, but the length of Joe's arms are in "cm" we need m or meters. Converting 70 cm to m = .7 m.

Now, we just put it all together - (31.5kg)(9.81m/s2)(.7m) = 216.31 J or 216.31 N m.
