Answer:
Subtract the mass of the cylinder from the mass of the cylinder when it contains gasoline. This is the mass of the gasoline. Divide this figure by the volume, 100 ml, to get the density.
Newton's second law of movement numerically expresses the connection among power and changes in moving. An adjustment in speed implies, by definition, that there is an increasing speed. An outer power acts from outside the arrangement of interest, an inside power acts between components of the framework. Just outer powers influence the movement of a framework, as per Newton's first law, but the inward powers really drop, as we will find.
The answer for the following problem is explained below.
Therefore the volume charge density of a substance (ρ) is 0.04 × C.
Explanation:
Given:
radius (r) =2.1 cm = 2.1 × m
height (h) =8.8 cm = 8.8 × m
total charge (q) =6.1× C
To solve:
volume charge density (ρ)
We know;
<u> ρ =q ÷ v</u>
volume of cylinder = π ×r × r × h
volume of cylinder =3.14 × 2.1 × 2.1 × × 8.8 ×
volume of cylinder (v) = 122.23 ×
<u> ρ =q ÷ v</u>
ρ = 6.1× ÷ 122.23 ×
<u>ρ = 0.04 × </u><u> C</u>
Therefore the volume charge density of a substance (ρ) is 0.04 × C.
Answer:
the net force is greatest at the points where the acceleration is maximum.
the net force is zero at the points where the object is in equilibrium.
Explanation:
net force of any object is defined by Newton's second law i.e F=ma
so when the object has zero acceleration it will experience zero net force and when the object has maximum acceleration it will experience greatest net force say when the object is in a maximum unbalanced state.
