Mechanical digestion is where the food is physically broken down into smaller pieces, such as in the mouth. Chemical digestion is where the food us chemically broken down into subtomic particles , starting with the saliva in the mouth and continuing throught the small intestine.

A potter's wheel has the shape of a solid uniform disk of mass 13.0 kg and radius 1.25 m. It spins about an axis perpendicular t

Fittoniya [83]

Answer: $10.82 kg-m^2$

Explanation:

Given

Mass of solid uniform disk $M=13 kg$

radius of disk $r=1.25 m$

mass of lump $m=1.7 kg$

distance of lump from axis $r_0=0.63$

Moment of inertia is the distribution of mass from the axis of rotation

Initial moment of inertia of disk $I_1=\frac{Mr^2}{2}$

$I_1=\frac{13\times 1.25^2}{2}=10.15 kg-m^2$

Final moment of inertia $I_f$ =Moment of inertia of disk+moment of inertia of lump about axis

$I_f=\frac{Mr^2}{2}+mr_0^2$

$I_f=10.15+1.7\times 0.63^2$

$I_f=10.15+0.674$

$I_f=10.82 kg-m^2$

A car goes around a curve of radius 60 m at a constant speed of 15 m/s. Which of the following values is the centripetal acceler

IRISSAK [1]

Answer:

3.75 m/s^2

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by the equation:

$a=\frac{v^2}{r}$

where

v is the tangential speed of the object

r is the radius of the trajectory

In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is

$a=\frac{(15 m/s)^2}{60 m}=3.75 m/s^2$

Two similar pyramids have base areas of 12.2 cm2 and 16 cm2. the surface area of the larger pyramid is 56 cm2. what is the surfa

Jlenok [28]

The surface area of the smaller pyramid is determined as 42.7 cm².

<h3>Area of pyramids</h3>

The base area of the two similar pyramid is given as follows;

Base area of large pyramid = 16 cm²

Base area of smaller pyramid = 12.2 cm²

<h3>Surface area of the similar pyramids</h3>

The surface area of the smaller pyramid is calculated as follows;

s₁/b₁ = s₂/b₂

s₁/12.2 = 56/16

s₁ = 42.7 cm²

Thus, the surface area of the smaller pyramid is determined as 42.7 cm².
