Answer:
endothermic energy or chemical energy
Explanation:
An endothermic process increases the enthalpy H of the system, during which the closed system (usually) absorbs thermal energy from its surroundings.
Chemical energy is the form of potential energy in which energy is stored in chemical bonds. The breaking of chemical bonds absorbs energy, while the formation of new bonds releases energy.

25,000 Feet = 7620m
PE = mgh where m is mass, g is gravity accel: 9.8 n h is height
= 90 x 9.8 x 7620
= 6720840J
= 6.72MJ
F = ma where m is mass, a is accel = gravity = 9.8
= 90 x 9.8
= 882N
Accel = gravity = 9.8m/s^2
KE = 1/2mv^2 where m is mass n v is vel
if no wind resistance, PE leaving airplane = KE at net
6720840 = 1/2 x 90 x v^2
v^2 = 149352
v = 386.5m/s
Answer:
Explanation:
From the exercise we know:
So, the average acceleration is:
The average force is:
Answer:
<em>Well, Many protists are harmful to humans, other animals and plants because they cause diseases and crop failures. However, some protists are actually beneficial to other creatures and are used by humans for various purposes. Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Hope That Helps!</em>
