Below is the correct explanation on Force except...
Force is a push or pull upon an object resulting from the object's interaction with another object.
Force is a scalar quantity.
The higher the force that acts on the object, the higher the effect that will be done by the object.
Force is a vector quantity.
What are the factors that can disrupt a structure?
Light
Gravity
Air resistance
Pressure
Average sea-level pressure is ...
360 mmHg
101.3 kPa
101.13 Pa
1.01 atm
What are the common disturbances that happen to the spacecraft when launching?
Noise disturbance
Atmospheric pressure
Rocket vibration
Radiation
Why are we having difficulty breathing and feel exhausted when climbing a mountain?
The molecule of oxygen collide with each other at high altitude
At high altitudes, the outside air pressure is lower than it is inside our lungs, making it more difficult to pull in the thinner air and for our veins to pump oxygen throughout the body.
The particles of oxygen do not exist at high altitudes and need some equipment to help humans to breathe
Our body is too tired and needs some rest.
Which of the following are true about pressure?
i. The force applied perpendicular to the surface or amount of force exerted per area.
ii. Compression force acting on the beverage can area will result in the decrease of size.
ii. The higher the force exerted on the surface of an object, the higher the pressure acting on the object.
iv. The higher the altitude, the lower the air pressure occurs.
i and ii only

i,ii and iii
All true
