Answer:

The speed of the car is 60 m/s.

Explanation:

It is given that,

Distance covered by the racing car, d = 900 m

Time taken by the car, t = 15 s

Let v is the speed of the car. The speed of any object is equal to the distance covered divided by total time taken as :

v=\dfrac{d}{t}

v=\dfrac{900\ m}{15\ s}

v = 60 m/s

So, the speed of the car is 60 m/s. Hence, this is the required solution.

Einhorn and Finkle are in a convenience store together. For a while they talk about stealing hot dogs and deodorant, for they ar
dangina [55]

We can conclude that Einhorn decides  not to steal according to the pre-conventional level where as Finkle decides per the conventional level according to Kohlberg's theory.

Explanation:

Kohlberg's theory is explained in three stages:

  1. The pre-conventional stage where sense of moral is controlled externally by rules of authority figures such as parents and teachers.An action is viewed according to the results obtained after the act.
  2. Conventional stage is when a person's morals are controlled by authority figures and their positive relation to the society norms.
  3. Post-conventional level relies on a person's principles and values where some laws are seen as unjust.

In this case, Einhorn recognizes that if you steal, you might end up being caught and punished because it is not accepted by authority figures and could led to punishment.  This is stage one. Finkle recognizes that stealing is unaccepted by the law and people in a society should avoid it.This is stage two.

We can conclude that Einhorn's decision not to steal is influenced by the pre-conventional level where as Finkle's by the conventional level according to Kohlberg's theory of moral development.

A car accelerates at a constant rate of 3 m/s2 for 5 seconds. If it reaches a velocity of 27 m/s, what was its initial velocity?
Kaylis [27]

The initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.

CALCULATE INITIAL VELOCITY:

The initial velocity of the car can be calculated by using one of the equation of motion as follows:

V = u + at

Where;

  • V = final velocity (m/s)
  • u = initial velocity (m/s)
  • a = acceleration due to gravity (m/s²)
  • t = time (s)

According to this question, a car accelerates at a constant rate of 3 m/s² for 5 seconds. If it reaches a velocity of 27 m/s, its initial velocity is calculated as follows:

u = v - at

u = 27 - 3(5)

u = 27 - 15

u = 12m/s.

Therefore, the initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.

Question 11 of 11 | Page 11 of 11
KiRa [710]

Answer:

Decreases the time period of revolution

Explanation:

The time period of Cygnus X-1 orbiting a massive star is 5.6 days.

The orbital velocity of a planet is given by the formula,

                                        v = √[GM/(R + h)]

In the case of rotational motion, v = (R +h)ω

                                         ω = √[GM/(R + h)] /(R +h)

Where 'ω' is the angular velocity of the planet

The time period of rotational motion is,

                                     T = 2π/ω

By substitution,

                                      <em>T = 2π(R +h)√[(R + h)/GM] </em>

Hence, from the above equation, if the mass of the star is greater, the gravitational force between them is greater. This would reduce the time period of revolution of the planet.

What is the component in a car engine that would detect the need for air?​
Ipatiy [6.2K]

Answer:

Control of air–fuel ratio

Oxygen sensors tell the ECU whether the engine is running rich (too much fuel or too little oxygen) or running lean (too much oxygen or too little fuel) as compared to ideal conditions (known as stoichiometric).
