Answer:
A.) 3.975 m/s
B.) 0.925 m/s
Explanation:
Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.
A) What is her average speed over the entire trip?
The average speed = (4.90 + 3.05)/2
Average speed = 7.95/2
Average speed = 3.975 m/s
B) What is her average velocity over the entire trip?
Since velocity is a vector quantity, that is, we consider both the magnitude and direction
Average velocity = ( 4.90 - 3.05)/2
Average velocity = 1.85/2
Average velocity = 0.925 m/s
B. Accelerate before entering the curve
C. Applying the brakes only after exiting the curve
D. Apply the accelerator throughout the entire curve
Correct answer choice is:
A) Decelerate before the curve.
Explanation:
Decrease your speed before overtaking a curve. Watch out for road symbols signaling of nearing curves so that you have enough time to reduce down before driving through the curve. It is desirable to drive below the posted speed limit as you progress and drive through curves. Turn as little as probable.
For safety concerning a curve, the correct answer is:
A. Decelerate before the curve.
When approaching a curve while driving, it is essential to slow down or decelerate before entering the curve. This allows you to maintain better control of the vehicle and reduce the risk of losing traction or skidding.
By reducing your speed before entering the curve, you can handle the curve more safely and smoothly, adjusting your steering and maintaining stability throughout the turn. Accelerating into a curve or applying the brakes only after exiting the curve can lead to unsafe driving conditions and increase the likelihood of accidents. It is always safer to slow down before taking a curve to ensure a safer driving experience.

Answer:
This new element belongs to the group 2.
Explanation:
In the periodic table, the vertical columns are called groups (or families). The elements in the same group share similar chemical and physical properties.
One of these properties is the same amount of outer valence electrons.
For example, in the group 1 the elements have 1 outer valence electron (If we assume that the element is in a neutral state which is without electrical charges).
If this new element has 2 electrons in its outer level it will belong to the group 2. The group 2 is well-known as alkaline earth metals.
For example, the magnesium (Mg) and the calcium (Ca) belong to the group 2.
