a. Remain in a fixed position.

b . Crystalline solids

<h3>What are the properties of solid?</h3>

Some properties of solid are:

solid have a fixed shape and a fixed volume
solid cannot be compressed
solids have high density.
force of attraction between the particles in solid is very strong.
The space between the particles of solids is negligible.
atoms are remain in a fixed position

The properties of crystalline solid

The atoms that components that make up the solid are all in definite positions
Atoms occur in a regular repeating pattern.

Hence , The particles of a solid are in fixed positions.

The arrangement of atoms in a solid causes it to have a definite are called crystalline solids.

The solids whose particles occur in a definite pattern are called crystaline solids.

<h3>What is a crystalline solid?</h3>

The term crystalline solid has to do with the type of solid in which the atoms that components that make up the solid are all in definite positions and occur in a regular repeating pattern.

The particles of a solid are found in fixed positions. The solids whose particles occur in a definite pattern are called crystaline solids.

An object is moving east with a constant speed of 30 m/s for 5 seconds. What is the object’s acceleration?

Shtirlitz [24]

Answer:

6 m/s²

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 30 m/s

Time (t) = 5 s

Acceleration (a) =..?

Acceleration is defined mathematically as:

Acceleration (a) = Velocity (v) /time (t)

a = v /t

With the above formula, we can obtain the acceleration of the object as follow:

Velocity (v) = 30 m/s

Time (t) = 5 s

Acceleration (a) =..?

a= v/t

a= 30/5

a = 6 m/s²

Therefore, the acceleration of the object is 6 m/s² due East.

Mary and her younger brother Alex decide to ride the carousel at the State Fair. Mary sits on one of the horses in the outer sec

Alex

Answer:

ωM = 1.7 rad/s

vM = 3.4 m/s

ωA = 1.7 rad/s

vA = 1.7 m/s

Explanation:

Calculation of the angular speed (ω)

We use the following formula for circular motion:

ω = θ / t Formula (1)

Where:

ω: angular speed (rad/s)

θ:angle that the particle travels (rad)

t: time interval (s)

Equivalence

1 revolution = 2π rad

Data

θ= 1 revolution = 2π rad

t = 3.7 s

We replace data in the formula (1):

ω = (2π rad) / (3.7s )= 1.7 rad/s

Because the angular speed depends only on the number of turns in a time interval then Mary's angular speed (ωM) is equal to Alex's angular speed (ωA).

ωM = ωA = 1.7 rad/s

Calculation of the tangential speed (v)

We use the following formula for circular motion:

v = ω*r Formula (2)

Where:

v : tangential speed (m/s)

ω: angular speed ( rad/s)

r : radius of the circular path (m)

Data

ωM = ωM = ω= 1.7 rad/s

rM = 2m : Mary's circular path radius

rA = 1m : Alex's circular path radius
