Answer : The density of an object is,
Solution : Given,
Mass of an object = 60 g
Volume of an object =
Formula used :
Now put all the given values in this formula, we get the density of an object.
Therefore, the density of an object is,
How long does it take light to travel 2462 mi, the distance between LA and NY? Provide the answer in ms. (1 mi= 5280 ft, 1ft= 12
in., 1 in.= 2.54 cm)
Please go through this detail by detail because Chemistry is a really hard subject for me to understand. Thank You:)

<h3>Further explanation</h3>Regular straight motion is the motion of objects on a straight track that has a fixed speed
Formula used
S = distance = m
v = speed = m / s
t = time = seconds
Straight motion changes regularly is the straight motion of objects that have a fixed acceleration
Formula used
V = vo + at
Vt² = vo² + 2as
St = distance on t
vo = initial speed
vt = speed on t
a = acceleration
The distance that light travels can be considered using the principle of irregular straight motion because it has a constant speed
The speed of light itself is 3.10⁸ m / s
The distance between LA and NY = 2462 mi, so we convert the units to m
Because 1 mi = 5280 ft, 1ft = 12 in., 1 in. = 2.54 cm, then
2462 mi = 2462 mi x 5280 ft x 12 in x 0.0254 m
2462 mi = 3962204,928 m
We use the straight-line motion formula
S = v x t
t = S : v
t = 3962204,928 m : 3,108 m / s
t = 0.0132073 s
conversion to milisecon :
t = 0.0132073 s x 1000 ms
t = 13,2073 ms
