What else can I help you with?
Is this statement true or false Air can cause friction?
true
Is it true or false that the greater the surface area of an object the greater the air resistance?
true
What statement about airplane and rocket is true?
Only one requires air molecules to generate lift.
True or false Projectiles always have a pointed shape?
False, a projectile is simply something that flies through the air irrespective of its shape. A football is a projectile. footballs are pointed though. Think: NERF bullets.
What is true statement about projectiles?
A true statement about projectiles is that they follow a curved trajectory known as a parabolic path when launched into the air, influenced primarily by gravity and initial velocity. The horizontal motion of a projectile is constant, while its vertical motion is affected by acceleration due to gravity. This means that, neglecting air resistance, the horizontal and vertical motions are independent of each other.
Is this statement true or false Air can cause friction?
true
The invention of an air brake provided railroad passengers increased safety and comfort and allowed for longer and faster trains true or false?
That is a true statement.
It's a high-pressure zone with rising air. true or false?
It's a high-pressure zone with rising air. true or false
How True or false cool air is heavier than warm air?
true
Is this statement true or false when Mass and air resistance affect the gravitational attraction between objects?
Mass certainly affects the gravitational attraction between objects; air resistance doesn't.
Frogs can breathe air through their skins true or false?
false
Does oxygen enter the blood in the air sacs true or false?
true
True or false the higher the altitude the lower the air pressure?
true?
Is this statement true or false The temperature at which water vapor begins to condense on solid objects is called the dew point.?
True. The dew point is the temperature at which air reaches saturation and water vapor in the air begins to condense into liquid water on surfaces.
Is it true or false that to float in air a blimp could be filled with helium?
False
When you climb a mountain the air pressure increase true or false?
False, air pressure goes down as altitude increases. Air acts like water in the sense that they are both fluids. If you are on the surface of the earth you are in the bottom of the fluid just like water the pressure is higher on the bottom. So when you increase altitude you are reaching the top of the fluid therefore decreasing pressure.
Is it true or false the force that drives air into the lungs come from air pressure?
No atmospheric pressure
