Answer:
C
Explanation:
Ore is usually refined once digged out to make certain things
Answer:
The correct option is (c).
Explanation:
In the conduction process, the electrons get transferred from one object to the other object. The electrons are freely charged particles. Protons cannot be moved freely.
In the given problem, the given aluminum pie plate is negatively-charged initially. After the conduction process, the plate gets electrically neutral.
It means that the excess of electrons from the aluminum pie plate is removed. Then, the number of electrons and the number of protons becomes equal. The plate becomes electrically neutral.
Therefore, the correct option is "Electrons were removed from the object".
There simple rules for series and parallel circuits.
For the series circuits we have the following rules:
1)The same current flows through each part of a series circuit.(<span>I = I1 = I2 = I3)
2)</span>The total resistance of a series circuit is equal to the sum of individual resistances.(<span>Req = R1 + R2 + R3)
3)The</span> voltage applied to a series circuit is equal to the sum of the individual voltage drops.(<span>V = V1 + V2 + V3)
</span>For the parallel circuits we have the following rules:
1)Voltage is the same across each component of the parallel circuit.(<span>: V = V1 = V2 = V3)
</span>2)The sum of the currents through each path is equal to the total current that flows from the source.(<span> I = I1 + I2 + I3)
3)The total resistance is equal to the sum of the reciprocal value of individual resistors in the circuit.
The x region represents the series circuit. The y region represents a combination of series and parallel circuit. This means that for y region we can apply laws for both series and parallel circuits.
So, all the equation can be applied to the y region.
However, not all equation can be applied to the x region. We can apply following equation to the x region:
1)</span><span>I = I1 = I2 = I3
</span>2)<span> V = V1 + V2 + V3
3)</span><span>Req = R1 + R2 + R3</span>
The momentum of truck is 20790 kg m/s
<em><u>Solution:</u></em>
Given that we have to find the momentum of truck
From given, 1155 kg truck has a velocity of 18 m/s
Therefore,
Mass = 1155 kg
Velocity = 18 m/s
<em><u>The momentum is given by formula:</u></em>
![p = m \times v](https://tex.z-dn.net/?f=p%20%3D%20m%20%5Ctimes%20v)
Where, m is mass in kg and v is velocity in m/s
Substituting the values we get,
![p = 1155 \times 18\\\\p = 20790](https://tex.z-dn.net/?f=p%20%3D%201155%20%5Ctimes%2018%5C%5C%5C%5Cp%20%3D%2020790)
Thus momentum of truck is 20790 kg m/s
Answer:
Dynamic flexibility
Explanation:
Dynamic flexibility can be generally defined as the ability of the body muscles and joints to move in full range of motion. High flexibility in these joints and muscles leads to the decreasing pain and injury in different parts of the body.
Proper warm up exercises are needed to be carried out that involves both the combination of controlling movements and stretching of the body, and this directly enhances the dynamic flexibility of the body.
The athletes and sports persons possesses a good dynamic flexibility of their body as they carry our different types of body exercises.
