Answer: 567 N
Explanation:
If the weight of the person and the bike are supported equally by the two tires, this means that the force acting on each tire, is half of the total weight.
We know that the gauge pressure in one tire, by definition, is equal to the force on the tire, over the contact surface between each tire and the road, so we can write:
P= F/A = (mrider g + mbike g) / A = (Fgrider + 7.5 kg. 9.8 m/s2) / 703 mm2 (1)
As the pressure data is given in lb/in2, it is needed to convert to N/mm2, as follows:
65.5 lb/in2 = 0.455 N/mm2.
Replacing in (1), and solving for Fgrider, we have:
Fgrider = 567 N
Answer:
Mass of object = 8kg
Explanation:
- <em>Since</em><em> </em><em>a</em><em>=</em><em> </em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>v</em><em>/</em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>t</em><em>,</em><em> </em><em>a</em><em>=</em><em> </em><em>(</em><em>1</em><em>8</em><em>-16</em><em>)</em><em>/</em><em>2</em>
<em>=</em><em> </em><em>1.5</em>
- <em>And</em><em> </em><em>F</em><em>=</em><em>ma</em><em> </em>
- <em>Force</em><em> </em><em>=</em><em>1</em><em>2</em>
- <em>a</em><em>=</em><em> </em><em>1.5</em>
- <em>m</em><em>=</em><em>?</em>
<em>You</em><em> </em><em>can</em><em> </em><em>now</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>your</em><em> </em><em>unknown</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>mass</em><em>.</em>
Answer:
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
Explanation:
There are two ways to connect electrical circuits, in series and in parallel.
Series circuits have the problem that when one element is damaged, the entire circuit is interrupted and runs out of power.
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
In Breaker it is connected in series so that when some maintenance is needed, all the energy can be interrupted simultaneously and if some equipment tries to consume a lot of energy, the circuit prevents this action by interrupting the energy of the entire circuit
