Define saturated and unsaturated fats ​

saturated fatty acid lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is atleast one double bond in the fatty acid chain. Saturated ftas tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.

Saturated fat: A fat that contains only saturated fatty acids, is solid at room temperature, and comes chiefly from animal food products. Some examples of saturated fat are butter, lard, meat fat, solid shortening, palm oil, and coconut oil. Saturated fat tends to raise the level of cholesterol in the blood.

Unsaturated fat: A fat that is liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, sunflower, safflower, or soybean oil. Unsaturated fat tends not to raise the level of LDL ('bad') cholesterol in the blood.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
