<h3>Hey Mate Here Is Your Answer</h3>

The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics. Kinematic equations are a set of equations that can derive an unknown aspect of the motion of a body if the other aspects are provided.

The density of the nugget is $19 g/cm^3$ and is made of gold

Explanation:

The density of an object can be calculated as

$d=\frac{m}{V}$

where

d is the density

m is the mass

V is the volume of the object

We have to note that density of an object actually depends on the material the object is made of (therefore, two objects made of the same material can have different mass and different volume, but they have same density).

For the nugget in this problem, we have:

mass: m = 38 g

volume: $V=2 cm^3$

So, its density is

$d=\frac{38}{2}=19 g/cm^3$

And by looking at the table, we see that this value corresponds approximately to the density of gold, so the nugget is made of gold.

what was the acceleration of the cart with Low fan speed cm/s squared? what was the acceleration of the cart with medium fan spe

ArbitrLikvidat [17]

Explanation:

The attached figure shows data for the cart speed, distance and time.

For low fan speed,

Distance, d = 500 cm

Time, t = 7.4 s

Average velocity,

$v=\dfrac{d}{t}\\\\v=\dfrac{500}{7.4}\\\\v=67.56\ cm/s$
