Bread is considered to be a heterogeneous mixture. It is a heterogeneous mixture because all of the components that are used to make the bread are physically separate.
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
A larger diameter wire has lower resistance. A lower resistance wire produces less heat for a given current flowing through it.
The potential energy that the ball has at the top of the tower is its kinetic energy when it hits the ground. The second ball has more potential energy at the top, because you did more work on it to carry it up there. So it has more KE at the bottom. (A)
Answer:
Explained
Explanation:
Thickness coating= t
wavelength of light λ = 500 nm
2 t =(m+0.5)λ
Here m = 0
t= λ/4
= 500/4 nm
= 125 nm
= 125×10^(-9) m
