History of the Philippines
The Philippines is a nation located in Southeast Asia near the Pacific Ocean. It comprises over 7,000 islands, serving as home to Filipinos. Here are several ways in which the strategic location of our country has contributed to shaping our history:

Answer:
The pen requires 7.2 mJ of energy to extend.
Explanation:
Provided:
Length = 1.8 cm
Spring constant = 300 N/m
Initial compression = 1.0 mm
Additional compression = 6.0 mm
Total compression = 1.0 + 6.0 = 7.0 mm
We need to determine the energy needed
This energy is equivalent to the variation in spring potential energy
Substitute the values into the formula
Therefore, a total of 7.2 mJ is needed to extend the pen.
A hiker proceeds 200 m west and subsequently another 100 m north, resulting in a displacement of 223 m. The direction can be determined using the trigonometric function where sin(angle) = opposite/hypotenuse, yielding an angle of 26.6 degrees. Therefore, the total displacement is 223 m at an angle of 26.6 degrees north of west.
Answer:
The initial speed at which the baseball is thrown is 20.58 m/s
Explanation:
To determine the time taken to reach the peak height in projectile motion, the formula is:
t = (u sin θ)/g
Where u = initial speed of the baseball =?
θ = angle of launch above the horizontal
g = gravitational acceleration = 9.8 m/s²
1.05 = (u sin 30)/9.8
u can be calculated as (1.05 × 9.8)/0.5
u = 20.58 m/s
Answer:
A) and B) are valid.
Explanation:
When an object remains at rest, it is indicative that no net force acts upon it.
The downward gravitational force from Earth must be counterbalanced by an upward force of equal magnitude in order to maintain rest.
This upward force is provided by the normal force, which adjusts to satisfy Newton’s 2nd Law and is always perpendicular to the surface supporting the object (in this instance, the ground).
At the molecular level, this normal force comes from the ground's bonded molecules acting like tiny springs, compressed by the object’s molecules, providing an upward restorative force.
Thus, statements A) and B) are true.
