The correct answer is: Option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.
Explanation:
The formula for the velocity is given as:
velocity = displacement/time;
It tells us how fast an object cover the distance between two points. In other words, we can say that how fast an object moves in unit time.
Acceleration, on the other hand, is defined as:
Acceleration = change-in-velocity/time
In Physics, we use the term "rate" of a certain quantity changes with time. Here that "certain quantity" is "change-in-velocity." Therefore, acceleration is said to be the rate of change in velocity.
Hence, the correct answer is option (B) Velocity is how fast an object moves and acceleration is the rate of change in velocity.

Answer:
D. Talk to a trusted adult about your worries.
Explanation:
We often come across situations where someone we love begins to get involved in dangerous situations that can compromise their physical and mental health. An example of this is when a friend or family member of ours is struggling with substance abuse.
It is normal in such a situation to be nervous, worried and not knowing how to help those we love, in which case it is important that you talk to someone you trust and be responsible with so that you can talk about their concerns. In addition, it is important that you trust this person and be able to trust the advice he gives.
Exercise is the physical bodily movement practiced to remain fit and healthy. It is not always safe to exercise in a gym. Thus, the statement is false.
Exercise has been defined as the physical movement that is practiced in order to maintain wellness, fitness, and health. It keeps the person from getting a disease like obesity, strokes, weight gain, and loss.
The exercise can be done in a gym or even at home. The gym uses many equipment and machines to maintain fitness. It increases the strength and endurance of the muscles and bones.
Although, the gym provides facilities but is a dangerous place as the environment unbalanced the thermodynamics of the internal body and lowers the gaseous exchange. Also, there may be some incidences while using the equipment and machines.
Therefore, the statement is false.
