To avoid engine failure, your friend suggests a gravitational powered elevator.
Explanation:
Answer:
Child maltreatment or child abuse is a phenomenon of sexual, physical, and/or psychological abuse of children.
Five different psychological perspectives of childhood maltreatment are as follows:
- Poverty is one of the biggest cause of childhood maltreatment that impact once psychological health.
- Child do not get proper care from their parents.
- Childrens are emotionally weak and anything negative thought can depress them.
- Lack of communication sometimes make children underconfident.
- Social descrimination on the basis of race and gender can impact a child psychological balance.
<span>The polarity of a water molecule
comes from the uneven distribution of electron density of hydrogen and oxygen
atom. The oxygen in the water molecule is more electronegative than the
hydrogen. Water has a <u>partial positive charge near the hydrogen atom and a
partial negative charge near the oxygen atom</u>. The result of this
electrostatic attraction results in the bond called hydrogen bond. Also, because
of this bond, it has the ability to dissolve most of the solutes due to its
polarity and bonding.</span>
This question involves the concept of the law of conservation of energy.
The spring constant of the cable is "915.6 N/m".
<h3>LAW OF CONSERVATION OF ENERGY:</h3>
According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only change from one form to another form. In this scenario, the elastic potential energy stored by the cable will completely be transformed into the gravitational potential energy at the highest point.


where,
- k = spring constant = ?
- m = mass = 160 kg
- g = acceleration due to gravity = 9.81 m/s²
- h = total height covered after launch = 12 m + 30 m = 42 m
- x = stretched length = 12 m
Therefore,
<u></u>
<u>k = 915.6 N/m</u>
<u></u>
