I believe the correct answer from the choices listed above is option A. Jonah finds a rusty nail outside. The nail is an example of <span>chemical weathering. Rusting of nail is a result of reaction of iron with water in air. Hope this answers the question. Have a nice day.</span>
Gaseous emissions are industrial products such as sulfur dioxide, carbon monoxide, and oxides of nitrogen also released during various manufacturing operations. Particulate control. Methods for particulate control tend to operate on a common principle.
the answer is B a freckle I just had this as a Study Island and got it right.
The graph between the strength of the magnet(number of paper clips picked) and battery is approximately a straight line.
For 25 coil, with increase of 1.5 V battery voltage, the electromagnet picks about 5 more clips. So, for a 7.5 V battery, it would pick about 30 paper clips.
For 50 coil, with increase of 1.5 V battery voltage, the electromagnet picks about 15 more clips. So, for a 7.5 V battery, it would pick about 30 paper clips.

Answer
</u>
The impulse on the second trial is smaller is smaller than in the first trial.
<u>Explanation
</u>
Impose of a body is that change in momentum during a time interval. If the change of momentum takes longer then, the impulse of a force is less. I a moving object hits a hard surface the rate of change of momentum is very high. e.i in the first trial, the egg breaks because it hits the hard surface(ground).
In the second trial, the foam cushion absorbs the shock and prolongs the time of impact with the egg hence decreasing the impulse.
