Air bags are kept in the steering wheel or
dashboard and expand during a serious collision, usually a front collision that
occurs at over 10 mph. To do its important job, an air bag comes out of the
dashboard at up to 200 mph, faster than the blink of an eye. It is estimated
around 10 inches of space to inflate. The force of an air bag can hurt those
who are too close to it. Driver and front seat passengers should be
moved as far back as practical, mainly people of short built. It is highly suggested
that you be seated no less than 10 inches away from the air bag. Therefore, the answer is letter b.
Children with low self efficacy will take a longer time to achieve their targets whereas those with high self effficacy will be more likely to find success easily
Answer:
The magnitude of the net current = 18 A.
Direction of the net current is along the negative z axis.
Explanation:
<u><em></em></u>
<u><em>Given:</em></u>
- Number of electrons flow through the given cross section,
- Number of electrons flow through the given cross section,
- Time interval for which the electrons and protons flow,
The current through a cross section is defined as the amount of charge passing through that cross section in unit time.
We know,
Charge on an electron,
Charge on a proton,
Therefore,
The amount of charge flowing due to electrons is given by
The amount of charge flowing due to protons is given by
The current flowing through the cross section because of the electrons is given as:
The negative sign shows that the current is due to the flow of negative charge, and the direction of current is always opposite to that of flow of negative charge i.e., electrons.
Thus, the direction of this current is along the negative z direction.
The magnitude of this current = 12 A.
The current flowing through the cross section because of the protons is given as:
The direction of this current is same as that of electrons,
The directions of the currents due to both, the electrons and the protons are along the negative z direction, therefore the magnitude of the net current is given as:
If the Sun were replaced by a 1-solar-mass black hole, then Earth wouldcontinue to orbit the black hole in precisely its present orbit. The planets would actually continue on in their orbits as if nothing had happened<span>.</span>
