15 degrees because a glass of water won't do anything to a bath tub of 15 degree water
That would be a the first law of newton's laws of motion because it stops from an external force
Answer:
Color, formation, gas, odor,
Explanation:
- change are a change in color
- formation of a precipitate
- formation of a gas
- odor change
- temperature change
Answer:
Explanation:
Volume per unit time flowing will be conserved
a₁v₁ = a₂ v₂
π r₁² x v₁ = π r₂² x v₂
(0.9 x 10⁻²)² x .35 = ( .45 x 10⁻² )² x v₂
v₂ = 1.4 m / s
First we write the corresponding kinematics equations:
a = -g
v = -g * t + vo
y = -g * ((t ^ 2) / 2) + vo * t + yo
Substituting the values:
y = - (9.81) * (((0.50) ^ 2) / 2) + (19) * (0.50) + (0) = 8.27m
answer:
the displacement at the time of 0.50s is 8.27m
