Answer:
Explanation:
l = 600mm = 0.6m
d = 40mm = 0.04m
hd = 30mm = 0.03m (diameter of the hole)
hl = 100mm = 0.1m (hole length)
modulus of elasticity for the aluminium = 85GN/m2
compressive load = 180kN
Answer:
A. A person would have the same mass, but weigh less.
Explanation:
Remember, even if you weigh less because of a change in gravity's force on your body, your body's mass is still the same.
Due to the principle of conservation of energy, the work done by the engine to move the scooter converts into kinetic energy of the scooter:
where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
There are asteroids, which are rocks that fly through the space, and meteors which are pretty much the same. The only difference is their sizes. There are also planets, big and small. The moon, the dwarf planet Pluto, and many more. There are probably thousands of other planets that we haven't quite yet discovered. Soon we will though. There are also billions of stars, such as the sun, and some others we don't have names for that form constellations.
Hope this helped!!
