How do you think a graph of deceleration would differ from a graph showing acceleration

A graph of acceleration would have to be a graph with an increasing slope, since you're going faster and faster

a graph of deceleration would have to be a graph with a negative slope since you are slowing down over time

Simply, a deceleration starts from top and goes down, and acceleration goes from bottom to top.

TRUE OR FALSE The time period of a simple pendulum does not depend upon mass, but depends, but depends on the size of the bob, b
Dimas [21]

Time period depends on the length of the pendulum and the force of gravity.

<h3>On what things time period depends?</h3>

The time period of a simple pendulum does not depend on mass and material of the bob. It depends on the length of the pendulum and the force of gravity because more length of the pendulum leads to more time to complete one cycle.

So we can conclude that time period depends on the length of the pendulum and the force of gravity.

As a train accelerates away from a station, it reaches a speed of 4.9 m/s in 5.1 s. If the train's acceleration remains constant
vodomira [7]
Acceleration is the rate of change of the velocity of a moving object. To determine the speed the object has at a certain time, we need to determine the acceleration first by dividing the speed with the time given. We do as follows:

acceleration = 4.9 m/s / 5.1 s = 0.96 m/s^2

To determine the velocity after 7.1 s, we multiply 7.1 s to the acceleration. 

speed or velocity = 0.96 x 7.1 = 6.52 m/s

What is the correct answer?
dexar [7]

Answer:

length=2

Explanation:

You simply find the zeros of the quartic polynomial

The factored form is (x+1)(x-5)(x-2)=0

The zeros become -1,5 and 2

Dimension 5 is already given and the question says length>width and 2>-1

Therefore length=2

Imagine you use Nitrogen as your gas. If you have the cold side as cold as you can without liquefying it (78 K), and run the hot
alina1380 [7]

Answer:

The efficiency of a Stirling engine is 74%

Explanation:

Given:

Temperature of gas when it is cold T_{1} = 78 K

Temperature of gas when it is hot T_{2} = 300 K

The efficiency of a stirling engine,

  \eta =1 - \frac{T_{1} }{T_{2} }

  \eta = 1- \frac{78}{300}

  \eta = 1-0.26

  \eta = 0.74

∴ \eta = 74 \%

Therefore, the efficiency of a Stirling engine is 74%

The speed for a car that went a distance of 125 miles in 2 hours time is ______. Question 2 options: 250 meters/sec 62.5 miles/h
Goryan [66]

Answer:

62.5 miles per hour

Explanation:

Speed = Distance travelled / Time taken

Speed = 125/2 = 62.5

You derive the units of the speed...by using the speed formula....,

Speed = Distance/Time

Speed = miles/hour

Hence the units for the speed = miles/hour
