What else can I help you with?
Before the 17th century what ideas did people have concerning motion velocity and acceleration?
There were many different ideas, but they all went something like this: Most people thought that the natural state of an object was at rest, and that force needed to be applied in order to keep an object moving at constant velocity. Of course, we now know that no force is needed for constant velocity, only acceleration.
What is needed to change speed into a velocity?
You have a velocity when both a speed and a direction is specified. This kind of magnitude is known as a "vector" - that is, when it is relevant to state a direction, as well as a magnitude, we speak about "vectors".
State five essential conditions needed for photosynthesis to take place?
The five essential conditions needed for photosynthesis to take place are sunlight, carbon dioxide, water, chlorophyll, and enzymes. Without any of these conditions, photosynthesis cannot occur effectively.
Does velocity affect motion inertia?
No, velocity does not affect an object's inertia. Inertia is the property of an object to resist changes in its state of motion, regardless of its velocity.
Is force needed to keep a body moving with unifom velocity?
No, once a body is moving with a constant velocity, no net force is required to maintain its motion. This is known as Newton's first law of motion, which states that an object will remain in its current state of motion unless acted upon by an external force.
When the velocity of a contraction is zero the contraction is?
When the velocity of a contraction is zero, the contraction is at a complete stop or in a state of static equilibrium.
What is meant by longitudinal dynamics of aircraft?
Longitudinal aircraft dynamics variables are (small) deviations from operating point or trim conditions state (components): u: velocity of aircraft along body axis v: velocity of aircraft perpendicular to body axis (down is positive) : angle between body axis and horizontal (up is positive) q : angular velocity of aircraft (pitch rate)
Do high velocity liquid molecules escape to the atmosphere?
High-velocity liquid molecules can escape to the atmosphere if they possess enough energy to overcome the intermolecular forces holding them in the liquid state. This typically occurs at the surface of the liquid, where molecules can transition into the gas phase through processes like evaporation. However, for most liquids under normal conditions, only a small fraction of molecules achieve this energy level. In extreme conditions, such as high temperatures, a greater number of high-velocity molecules may escape.
6 inch duct diameter 40 feet long 8 insulation carring 50 degree air in a100 degree attic what is the steady state heat gain?
The air flow velocity is needed to answer this question.
Is migration certificate needed within maharashtra state?
No, migration certificate is not needed within the state.
What are the conditions to achieve balance force?
To achieve balanced forces on an object, the magnitudes and directions of the forces acting on the object must be equal and opposite. This equilibrium state will result in the object either remaining at rest or moving at a constant velocity.
What object has the least inertia?
The magnitude of inertia of an object is we consider the velocity and mass.The object that has least inertia is object that has small mass and velocity.This because the small mass and velocity the easiest it to stop or stop it.As we know that inertia is the tendency of object to remain its state in rest or in uniform velocity in straight line.Small massan velocity of object the small tendency of object to remain it state in rest or in uniform velocity in straight line.
