Hatshy [7]3 years ago
5 0

Answer:

The rock will sink because it is more dense than water.

Explanation:

Katarina [22]3 years ago
3 0

Explanation:

Substances with their density less than that of water which is 1 g/cm³ will float on it whiles those greater than that of water will sink into the water

From the question the density of the object is greater than that of water so the object will sink into the water

Hope this helps you

Which of ONE of the following four elements has the most metallic properties?
olchik [2.2K]

Answer:

12 (Magnesium- Mg)

Explanation:

Looking at the four numbers, we have:

Magnesium, Silicon, Sulfur, and Chlorine.

We can eliminate two of the answers immediately just by looking at the periodic table.

Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's <em>definitely</em> not it. That leaves Magnesium and Silicon.

Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.

Metaloids are elements that have a mix of both<em> metal</em> and<em> nonmetal </em>properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-

We can say Magnesium has the most metallic properties.

hope this helps!!

A resistor converts 350 J of electrical energy to other forms of energy. What is the amount of
Helga [31]

Answer:

50C

Explanation:

Given parameters:

Electrical energy  = 350J

Potential difference  = 7V

Unknown:

Amount of charge = ?

Solution:

To solve this problem, use the expression below;

  E  = q x v

E is the electrical energy

q is the quantity of charge

v is the voltage

Insert the parameters and solve for q;

            350 = q x 7

            q = \frac{350}{7}

             q = 50C

A proton is released from rest at the origin in a uniform electric field that is directed in the positive x direction with magni
Vika [28.1K]

Explanation:

It is given that,

Electric field, E=950\ N/C

We need to find the change in the electric potential energy of the proton-field system when the proton travels to x = 2.5 m

From the conservation of energy, the loss in potential energy is equal to the gain in kinetic energy and kinetic energy is is equal to the work done.

W=F\times x

W=q\times E\times x

W=1.6\times 10^{-19}\times 950\times 2.5

W=3.8\times 10^{-16}\ J

So, the change in electric potential energy of the proton field system is 3.8\times 10^{-16}\ J. Hence, this is the required solution.
