Answer:

Velocity is measured in both magnitude and direction (vector quantity) while speed is only measured in magnitude (scalar quantity)

Explanation:

We see velocity is measured using displacement and acceleration which is a vector quantity, as we see below;

[tex]{ \rm{ \vec v} = \vec u + \vec at} \\ { \rm{ \vec {v}^{2} = \vec {u}^{2} + 2 \vec as }} \\ { \rm{ \vec s = \vec ut + \frac{1}{2} \vec a {t}^{2} }}[/tex]

But for speed, distance (scalar quantity) is only measured;

[tex]{ \rm{speed = \frac{ d}{t} }} \\ [/tex]

The difference between displacement and distance is that;

Displacement: The direction matters, if a body is moving to north for x meters, then displacement is +x meters, if the body turns back to south, the displacement is -x meters. So total displacement is (-x) + (+x) = 0

So, direction matters.

Distance: Direction doesnot matter, if body moves to north x meters, and again reverses to south for x meters, total distance is (x + x) = 2x

Answer:

The anwser is A. Insulators

Explanation:

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

The potential enegry can be increased by. Increasing the mass of the object, by varying the distance between the two objects, decreasing the kinetic energy of the molecules by freezing, by compressing or stretching.

Explanation:

And because magnets have north and south poles ,the potential energy depends not only on the position within a field , but also the magnets orientation.

Answer:

The potential enegry can be increased by. Increasing the mass of the object.

Answer:

The Government of Colombia is a republic with separation of powers into executive, judicial and legislative branches. Its legislature has a congress, its judiciary has a supreme court, and its executive branch has a president. The Republic of Colombia is a unitary republic comprising 32 departments, and one capital district. Since Colombia adopts the representative, republican, and democratic form of government, it is governed by representatives of the people, who are elected through direct vote. As a Civil Law country, Colombia’s legal system is mainly based on codes and laws rather than jurisprudence. One of the main characteristics of civil law countries is that their legal system does not recognize the jurisprudence as part of their legal bodies, which means that court’s decisions are only binding for the parties involved rather than for everyone. Judicial decisions are applied case by case and serve as a reference for other judges. However, in Colombia, as well as in some other civil law countries, the high courts’ decisions have gained more power and their scope is not limited as it was previously. In certain occasions, especially in high profile cases where the matters are controversial, a court’s interpretation of the law is just as important as the written law itself. The Colombian National Constitution of 1991 states in Article 1 that “Colombia is a social state of law, organized in the form of a unitary, decentralized republic, with autonomy of its territorial entities, democratic, participatory and pluralist." This means that the central government has the power to make the most important political decisions. Colombia only has a legislative authority, which is responsible for making the laws for the entire territory. The country is divided in territorial entities called departments (equivalent to states in the U.S.) that are separated into districts and local municipalities. These entities do not have legislative or judicial authority. However, as the executive branch of Colombia is administratively decentralized, there are representatives in the departmental, district, and municipal department levels. The representatives in these three levels have certain limited powers that are independent from the central authority.

Answer:

The extremely low pressure of the partial vacuum inside the tank allows the pressure of the air outside the tank to crush it. When the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can can withstand, the can will be crushed.

Answer:

Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.

Answer:

Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.
