Answer:

ANSWER KEY Relationship of Magnets CER

Claim (Write one sentence stating the cause and effect relationship of magnets.)

In magnets, like poles repel, whereas opposite poles attract.

Evidence (Provide scientific data to support your claim. The evidence should include how attraction and repulsion is demonstrated by the matchbox cars and the position of the poles of the magnets.)

When the North Pole of the magnet (orange) and the South Pole of the magnet (green) came close to one another they attracted and when the North Pole of the magnet (orange) and the North Pole of the magnet (orange) came close to one another, they repelled. The South Pole against the South Pole repelled as well. Therefore confirming that opposite poles attract and like poles repel. We were able to record data to show the distance that each car traveled by using either attraction or repulsion. Four out of five cars give evidence that the repulsion, created by opposing poles, had the stronger force.  

Reasoning (Explain why your evidence supports your claim. Describe how the poles of the magnet determine whether magnets attract or repel and how your evidence allowed you to see the force of the attraction or repulsion.)

Magnets have an invisible force around them, called the magnetic field, which has North and South Poles. The opposite poles attract and like poles repel. We saw this through completing the activity by seeing and measuring the distance that was traveled by each car using attraction and repulsion.

For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in kJ. We use the conversion: 1000 cal = 4.184 kJ The solution is as follows:

A person takes a trip, driving with a constant speed of 94.5 km/h except for a 22.0 min rest stop. If the person's average speed
qwelly [4]
From the average speed you can fix an equation:

Average speed = distance / time

You know the average speed = 65.1 kg / h, then

65.1 = distance / total time,

where total time is the time traveling plus 22.0 minutes

Call t the time treavelling and pass 22 minutes to hours:

65.1 = distance / [t + 22/60] ==> distance = [t + 22/60]*65.1

 
From the constant speed, you can fix a second equation

Constant speed = distance / time traveling

94.5 = distance / t ==> distance = 94.5 * t

The distance is the same in both equations, then you have:

[t +22/60] * 65.1 = 94.5 t

Now you can solve for t.

65.1t + 22*65.1/60 = 94.5t

94.5t - 65.1t = 22*65.1/60

29.4t = 23.87

t = 23.87 / 29.4

t  = 0.812 hours

distance = 94.5 km/h * 0.812 h = 76.7 km

Answers: 1) 0.81 hours, 2) 76.7 km
