Um corpo de massa 100kg encontra-se a uma altura de 180m numlocal onde g= 10m/s² quando e solto. qual a sua energia potencial gravitacional após de queda? qual sua energia cinética ao atingir o solo? despreza todas as forças de resistência ao movimento

U = 180000 Joules

K = 180000 Joules

Explanation:

C

U = mgh

Then

U = (100)(10)(180) = 180000 Joules

When this object falls in the earth this potential energy is transforming in kinetical energy, but how the energy is conserving, this object has the same energy; then

K = 180000 Joules

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
