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.

In colder weather, people usually wear coats when going outside. Coats keep us warm because of the material of the coat. Our body supplies the heat, and the material helps to trap body heat and keeps the heat from escaping into the air. This is what keeps us warm.

Answer:

5) Displacement = +3.125 m

Displacement is in the same direction as the force vector.

6) Force = -53.89 N

Force is in an opposite direction relative to the displacement.

Explanation:

5) We are given;

Force; F = 160 N.

Workdone; W = +500 J

Now, formula for workdone is;

W = Force × displacement

Thus, displacement = Work/force

Displacement = 500/160

Displacement = +3.125 m

Thus, displacement is in the same direction as the force vector.

6) We are given;

Displacement; d = 18 m.

Workdone; W = -970 J

Like in the first answer above,

Workdone = Force × Displacement

Thus;

Force = Workdone/Displacement

Force = -970/18

Force = -53.89 N

Since force is negative and displacement is positive, it means force is in an opposite direction relative to the displacement.

The lever has two “arms”:

The load arm is the portion of the lever directly connected to the load.

The effort arm is the portion of the lever to which we apply the effort, or input force.

The formula of the mechanical advantage(MA) of a lever is given as

MA = load/effort.

Given,

load = 2kg , effort = 30cm

MA = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]

MA  = 0.06 cm

Therefore,

A 2-kg mass placed 30-cm to the left of the fulcrum is balanced by a 2-kg mass placed  0.06 cm to the right of the fulcrum.

Answer:

I found it would be quadrupled if it was doubled

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:

where

m is the mass of the object

v is its speed

From the equation, we notice that the kinetic energy is:

Directly proportional to the mass

Proportional to the square of the speed

In this problem, the initial kinetic energy of the object is

K = 100 J

Later, the speed of the object is doubled:

v' = 2v

Therefore, the new kinetic energy will be

So, we see that the kinetic energy will quadruple.

Answer:

2.86m/s²

Explanation:

[tex]\boxed{average \: acceleration = \frac{change \: in \: velocity}{time} }[/tex]

Car's average acceleration

[tex] = \frac{20 - 0}{7} \\ = 2.86 \: m/ {s}^{2} \: (3 \: s.f.)[/tex]

The reason why the change in velocity over time is average acceleration is because we are finding the total difference in velocity and dividing it against the total duration. This means that the acceleration of the car can vary throughout the 7 seconds (may not be a constant acceleration) but on average, the car's acceleration 2.86m/s², to 3 significant figures.

Change in velocity

= v -v₀

= final velocity -initial velocity

Since the car is at rest at the beginning, the initial velocity (v₀) is 0m/s.

Answer:

Average acceleration

As we are already knowing that

[tex] \sf Acceleration_{Avg} [/tex] = TA/T

TA = Total acceleration

T = Time

A = 20/7

A = 2.85 m/s²

C. His victory against a superior British foe inspired the American troops.

Explanation:

John Paul Jones is considered the hero in the Revolutionary War. He is known as the Father of the US Navy.

In the Revolutionary War, Jones sided with the American colonists against the British and took hold of naval ships. In 1779, when the British warship Serapis was in conflict with the American warship Bon Homme Richard, Jones plugged the American warship with the Britisher's warship and tossed a grenade into the opponent warship. Thus when Jones was victorious in the war, this boosted the American spirits for the war.

Therefore, option C is the correct answer.
