The formula that relates the 3 variables, namely: mass,
volume, and density is: Density = mass / volume.
Let us identify each variable:
Density - more accurately called the volumetric mass density of a
substance is its mass per unit volume. It is a key concept that examines how
materials communicate in a lot of things, i.e weather, material sciences,
engineering, and other fields of science.
Mass – defined as a property of
a physical body in Physics, and when a net force is applied,
it results to the measure of a specific
object’s resistance to acceleration.
Volume - <span>contained or
occupied by the space of a substance or shape (either by a solid, liquid, gas
or plasma state)</span>
Answer:
- 8.33 x 10⁻³ rad /s ( anticlockwise)
Explanation:
The rotational movement of beetle and turntable is caused by torque generated by internal forces , we can apply conservation of angular momentum.
That is ,
I₁ ω₁ = I₂ω₂ , ω₁ and ω₂ are angular velocity of beetle and turntable respectively.
ω₁ + ω₂ = .05 radian /s ( given )
Momentum of inertia of beetle I₁ = mass x (distance from axis)²
= 15 x 10⁻³ x R² ( R is radius of the turntable )
Momentum of inertia of turntable I₂ =1/2 mass x (distance from axis)²
= 75/2 x 10⁻³ x R² ( R is radius of the turntable )
I₁ ω₁ = I₂ω₂ ,
15 x 10⁻³ x R² x ( .05 - ω₂ ) = 75/2 x 10⁻³ x R² ω₂
15 x ( .05 - ω₂ ) = 75/2 x ω₂
.75 - 15ω₂ = 37.5ω₂
.75 = 52.5 ω₂
ω₂ = - 14.3 x 10⁻³ rad /s ( anticlockwise)
Answer:
KE = 1.05 x105 Joules
Explanation:
KE = 4 * (1.04653 x 105 J) = 4.19 x 105 Joules.
Igneous rocks are conglomerates, predominantly composed of rounded
gravel
Explanation:
The statement that igneous rocks are conglomerate predominantly composed of rounded gravel is not correct. Igneous rocks are rocks formed from magma that cools and solidifies.
- Conglomerates are sedimentary rocks that are made of rounded clasts in a matrix.
- They differ from igneous rocks that crystallize from molten magma.
- Sedimentary rocks are usually derived from the process of weathering, erosion, transportation and deposition on the earth surface.
- Igneous rocks forms from crystallized magma which can be on the surface or deep within the crust.
