So this aint about school but I need some help. So I like my best friends brother and he know I like him from rumors but I want him to know I like him without someone doin it for me. I have liked him since fourth grade. I'm now in 7th and so is he. He said he liked me but than got a gf and now I don't know if he likes me or not. I guess you can say were some what friends. I try not to lile him but it's to hard cuz I really really reayyy like him. He's like a new level of happiness for me. But please tell me how i can tell him I lile him. If any of my friends see this im sorry.

first off if he has a gf, I wouldn’t tell him. But if they’re not together anymore than I say tell him girl #

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

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
