A car traveling at a constant speed goes around a sharp curve. Is the car accelerating? Explain.

1 answer:

7 0

The answer is: Yes, the car is accelerating because it is changing direction as it goes around the curve.

- Because the direction of motion of an object even if the object is maintaining a constant speed still count as acceleration.

- Acceleration is a change in velocity, either in its magnitude i.e speed or in its direction or both.

- So, In a uniform circular motion, the direction of the velocity changes constantly, So there is always an associated acceleration, even though the speed might be constant.

-So when you go around a sharp curve if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction.

Answer:

The increasing order of conductivity is O< Ge< Mn.

Explanation:

Electrical conductivity is defined as the measure of the ability of a material to conduct electrical current through it. The conductivity depends on the atomic and molecular structure of the material.

Metals are good conductors because they have a structure with many electrons with weak bonds, and this allows their movement instead non-metals have between four and eight valence electrons, which lack this tendency.

The conductivity increases in the periodic table from top to bottom and from right to left.

oxygen is a nonmetal therefore it is a bad conductor.

Germanium is a metalloid whose conductivity is greater than a nonmetal and worst than a metal.

Manganese is a metal,in this case, it is a good conductor.

Problem:

In a gender based experiment, the blood pressure of different ages of men is been checked and recorded to determine if there is any correlation. What will be the independent, dependent and controlled variables?

Answer:

A controlled variable is the variable that is left constant throughout the course of an experiment. The controlled variable here is the gender.

A dependent variable is the variable that is been determined or measured during the course of an experiment. The dependent variable here is the blood pressure.

An independent variable is the variable that is intentionally or decidedly altered during the course of an experiment. The independent variable here is the age.
