Answer:

Density, d=19.3\ g/cm^3

Explanation:

Mass of the sample of gold, m = 38.6 grams

Volume of gold sample, V=2\ cm^3

The density of gold sample is given by mass per unit volume. Mathematically, it is given by :

d=\dfrac{m}{V}

d=\dfrac{38.6\ g}{2\ cm^3}

d=19.3\ g/cm^3

So, the density of the sample of gold is 19.3\ g/cm^3. Hence, this is the required solution.

Density = Mass ÷ Volume

Your mass = 38.6 grams
Your volume = 2 cm3

38.6 ÷ 2 = 19.3 grams per cm3

Mason notices that his boat sinks lower into the water in a freshwater lake than in the ocean. What could explain this?
suter [353]

<u>Answer </u>

D. Salt water is denser than freshwater.

<u>Explanation</u>

A boat is able to float on water because it experiences an upthrust upwards.

The magnitude of the upthrust depends on the density of the liquid.

When the liquid is denser the boat will experience a great upthrust as compared to when in a less dense liquid.

If the boat sinks lower in the freshwater than in salty water, then Salt water is more dense than freshwater.

A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by x = 18.0t and y =
In-s [12.5K]
Position:                 x = 18t    y = 4t - 4.9t²

First derivative:        x' = 18      y' = 4 - 9.8t

Second derivative:    x'' = 0        y'' = - 9.8


Position vector:      P  =  (18t) i  +  (4t - 4.9t²) j

Velocity vector:      V  =  (18) i  +  (4 - 9.8t) j

Acceleration vector  A  =              (- 9.8) j
