the earth
Explanation:
because the moon is blocking the light of the sun
Answer:
The maximum potential energy of the child will be maximum at the two end points.
The maximum kinetic energy of the <em>child </em>occurs at the lowest point of the swing.
The potential energy of the child depends on the displacement of the child.
P.E = mgh
The maximum height attained occurs at the two end points of her swing motion.
Thus, the maximum potential energy of the child will be maximum at the two end points.
The kinetic energy of the child depends on the velocity of the child
K.E = ¹/₂mv²
The maximum velocity of the swing occurs at the lowest point of the swing.
Thus, the maximum kinetic energy of the child occurs at the lowest point of the swing.
Hope this helps!
Answer:
B. It is highly flammable.
Explanation:
Chemical properties deal with how the substance will behave when brought into contact with other substances, and usually have to do with it undergoing some kind of reaction. Flammability is a chemical property.
Density, melting point, and color are all considered physical properties.
Answer:
q1 = mCpΔT
= 18.016g × 1.84J/g.K × (418.15-373.15)
= 1491.72 J
q2 = n×ΔH vap
= 1mol ×44.0kJ/mol
= 44KJ
∴ qtotal = q1+ q2
= 1.498kJ + 44.0kJ
= 45.498KJ
Explanation: The heat flow can be separated into steps.all that is being observed at a constant pressure,the heat flow is equal to the enthalpy.
Answer:
Explanation:
MM of I2 = 2 (127 g) = 254 g/mol
0.065 mol I2 x 254g I₂/ 1 mol I₂ = 16.5 g I2
