Answer:

b.They include familiar metals such as gold, silver, copper, and nickel.

They include familiar metals such as gold, silver, copper, and nickel.

Transition metals are like main group metals in many ways: They look like metals, they are malleable and ductile, they conduct heat and electricity, and they form positive ions.

"A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile."

"Transition metals are placed between s−block and p−block elements in periodic table. They are termed as d-block elements. These metals are unstable and exhibit transitional behavior between s block and p block elements, hence the name transition metals."

"Electricity is defined as the rate of flow of charges in a conductor."

Electricity is defined as the effects of an electric charge. An example of electricity is the force that powers a light bulb. An example of electricity is lightning. An example of electricity is static electricity, the buildup of electric charges on an object's surface.

Answer:

r = 0.849 m

Explanation:

Given that,

The masses of two objects, [tex]m_1=m_2=2\times 10^2\ kg[/tex]

The force between the objects, [tex]F=3.7\times 10^{-6}\ N[/tex]

We need to find the distance between the masses. The force between two objects is given by the relation as follows :

[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]

r is the distance between them

[tex]r=\sqrt{\dfrac{Gm_1m_2}{F}} \\\\r=\sqrt{\dfrac{6.67\times 10^{-11}\times (2\times 10^2)^2}{3.7\times 10^{-6}}} \\\\r=0.849\ m[/tex]

So, the distance between them is 0.849 m.

Explanation:

We are given:

Mass of Neptune = 1.03 * 10²⁶ kg

Distance from the center of Neptune (r) = 2.27 * 10⁷

now, computing the value of the acceleration due to gravity (g)

Finding g:

We know the formula:

g = G(mass of planet) / (r)²

g = [6.67 * 10⁻¹¹ * 1.03*10²⁶] / (2.27*10⁷)                      [since G is 6.67*10⁻¹¹]

g = (6.87 * 10¹⁵) / (5.15 * 10¹⁴)

which can be rewritten as:

g = (6.87 * 10¹⁵ * 10⁻¹⁴) / 5.15

g = (6.87 * 10¹⁵⁻¹⁴) / 5.15

g = (6.87/5.15) * 10

g = 1.34 * 10

g = 13.4 m/s² (approx)

Answer:

A) The bowling ball will hit the ground first. It is heavier, which has greater density, allowing it to reach the ground first.

B) Feather. If you want to be able to blow a bowling ball in a vaccum cleaner, it's almost impossible since it's very heavy. If it's a feather, it would be easier as it's light and the air inside it is able to force it down.

Explanation:

Answer:

[tex]u = 4.56m/s[/tex]

[tex]T = 0.94s[/tex]

Explanation:

See comment for complete question

Given

[tex]h = 106cm[/tex] --- Height

Solving (a): The initial speed

To do this, we make use of the third equation of motion

[tex]v^2=u^2+2ah[/tex]

In this case:

[tex]v = 0m/s[/tex] --- final velocity at the maximum height

[tex]a = -g = -9.8m/s^2[/tex]

[tex]h = 106cm[/tex]

Convert height to metres

[tex]h = 1.06m[/tex]

Substitute these values in [tex]v^2=u^2+2ah[/tex]

[tex]0^2 = u^2 +2 *(-9.8) * 1.06[/tex]

[tex]0^2 = u^2 -20.776[/tex]

Collect Like Terms

[tex]u^2 =20.776[/tex]

Take the positive square root of both sides

[tex]u =\sqrt{20.776[/tex]

[tex]u = 4.55806976691[/tex]

[tex]u = 4.56m/s[/tex] --- approximated

Hence, the initial velocity is 4.56m/s

Solving (b): Time spent in the air.

This will be solved using the first equation of motion.

[tex]v = u + at[/tex]

Where:

[tex]v = 0m/s[/tex] --- final velocity at the maximum height

[tex]a = -g = -9.8m/s^2[/tex]

[tex]u = 4.56m/s[/tex]

So, we have:

[tex]0 = 4.56 - 9.8t[/tex]

Collect Like Terms

[tex]9.8t = 4.56[/tex]

Make t the subject

[tex]t = \frac{4.56}{9.8}[/tex]

[tex]t = 0.46530612244[/tex]

[tex]t = 0.47s[/tex] --- approximated

The above is the time it reaches the maximum height.

The time it stays in the air is:

[tex]T = 2t[/tex]

This gives:

[tex]T = 2*0.47s[/tex]

[tex]T = 0.94s[/tex]
