Answer:
The important thing about emotional health is being in control of their thoughts, feelings, and also behaviors.
Explanation:
Emotional health is an important part of overall health. People who are emotionally healthy are in control of their thoughts, feelings, and behaviors. They're able to cope with life's challenges. They can keep problems in perspective and bounce back from setbacks.
To solve this problem we should apply Newton's third law for which it is defined that there must be an equal reaction in the opposite direction.
From this law, if Car A generates a force on car B, that car must have opposed a force exactly the same but in the opposite direction. The car A moved to the left and generates a force of 900lb so the magnitude of the force in the car B is also 900lb but to the right (opposite direction to the first car)
The correct option is 900lb to the right.
<u>Answer</u>:
"Chemical bonds are formed or broken" is NOT true about physical properties.
<u>Explanation</u>:
Any characteristic that could be determined without changing composition of the substance is called as physical properties.A object can be observed or described using a physical property. Physical properties of a substance include only size, shape and physicality in a general aspect.
It does not include how its chemical properties like bonds or which type of elements combined to form a compound likewise. Hence formation or breaking of chemical bonds does not determine the physical properties
