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.
The Doppler Effect...
<span>It describes an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.</span>
F = mass x acceleration
We have mass = 200kg
and acceleration = 3 m/s^2 so...
F = (200)(3)
F = 600 N
If Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.
<h3>What is average speed? </h3>
The average speed of an object is the ratio of total distance to total time of motion.
V = total distance/total time
For Frank to be in Tampa by noon, he must spend atleast 4 hours 30 minutes on the road.
18.3 mph = d/4.5 h
d = 82.35 miles
The distance between Gainesville and Tampa is 82.35 miles.
Thus, we can conclude that, if Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.
