1. A 4kg ball is on a 5m ledge. if it is pushed off the ledge, how much kinetic energy will it have just before hitting the ground? 2. a 3 kg rock sits on a 0.8 meter ledge. how much gravitaional potential energy does it have while it sits on the shelf?

b. what will happen to the gravitaional potential energey if the rock falls off the shelf

c. if it is pushed off, how fast will it be going at the bottom just before it hits the ground?

3. a 0.003 kg fog jumps into the air at 3 m/s. what is the energy of the movement of the frog?

4. as the frog rises in the air he gains (blank) energy and loses (blank) enegry since he slows down.

5. assuming that all of the kinetic energy of teh fog is converted to potential enegery at the top of his jump before he falls back down to the ground, what height would he acheive with this jump?

Whoever answers all five questions will get brainliest and a five star rating/thanks please help me asap this is due tomorrow!!! :(

watch you tube or play clash royale, mainly clash royale

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
