so as we know potential energy is stored energy which is the top of the roller coaster when you increase the pull of gravity you will increase potential energy and kinetic energy is a theory that states that particles of matter are always in motion. and that the amount of motion depends on the amount of energy in the particles so for short kinetic energy is energy in motion which is the roller coaster when its moving. mechanical energy is the same thing energy in motion such as a moving vehicle which is still the roller coaster when its moving. conservation of energy from the roller coaster is not destroyed nor created the energy changes form.
so the potential energy is stored in the top of the roller coaster. kinetic energy is when the roller coaster is in motion same thing for mechanical and conservation is the energy that is being released from the roller coaster is neither destroyed nor created.
i hope this makes sense XD
Answer:
OBr₂
Explanation:
<em>The ionic character depends on the difference of electronegativity between the elements. The higher ΔEN, the greater the ionic character.</em>
SBr₂
ΔEN = |EN(S)-EN(Br)| = |2.5-2.8| = 0.3
OBr₂
ΔEN = |EN(O)-EN(Br)| = |3.5-2.8| = 0.7
SeCl₂
ΔEN = |EN(Se)-EN(Cl)| = |2.4-3.0| = 0.6
TeI₂
ΔEN = |EN(Te)-EN(I)| = |2.1-2.5| = 0.4
SCl₂
ΔEN = |EN(S)-EN(Cl)| = |2.5-3.0| = 0.5
OBr₂ is the molecule with the most ionic character.
Answer:
Mass = 1.42 g
Explanation:
Given data:
Amount of heat absorbed = 4.56 j
Initial temperature = 29°C
Final temperature = 36°C
Mass of iron metal = ?
Specific heat capacity of iron = 0.46 j/g.°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 36°C - 29°C
ΔT = 7°C
Q = m.c. ΔT
m = Q / c. ΔT
m = 4.56 j / 0.46 j/g°C . 7°C
m = 4.56 j /3.22 j/g
m = 1.42 g
Answer:
Ligands
Explanation:
Ligands are small molecules that transmit signals in between or within cells. Ligands exert their effects by binding to cellular proteins called receptors.
