Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.

Explanation:

For equilibrium, $\sum M = 0$ .

So, $8 m \times mg - (10 m) T_{1}$ = 0

$T_{1} = \frac{8 \times mg}{10}$

= $\frac{8 \times 90 \times 9.8}{10}$

= 705.6 N

Also, for equilibrium $\sum F_{y}$ = 0

$T_{1} + T_{2} - mg$ = 0

or, $T_{2} = mg - T_{1}$

= $90 \times 9.8 - 705.6$

= 176.4 N

Thus, we can conclude that the tension in the first rope is 176.4 N.

Describe your ecological footprint. What do the results mean? What are some things

bixtya [17]

The ecological footprint finds the person demand on natural demand.

<h3>What is ecological footprint?</h3>

The ecological footprint is the method promoted by the Global Footprint Network to find human demand on natural capital. The quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system.

Some things which could do to reduce your footprint is Reduce Your Use of Single-Use, Disposable Plastics, Switch to Renewable Energy, Eat Less Meat, Reduce your Waste, Recycle Responsibly, Drive Less, Reduce Your Water Use, Support Local.

Thus, the ecological footprint is to find person demand on natural demand.

Atomic nuclei of almost all elements consist of

wolverine [178]

<h2>Answer: protons and neutrons. </h2>

The atomic nuclei of almost all elements consist of protons and neutrons.

The nucleus of an atom has very small dimensions. However, it <u>occupies its central part and concentrates more than 99% of its total mass. </u>

It is in the nucleus that the protons (positive charge) and neutrons (neutral charge) are found.
