What else can I help you with?
Does Motion occurs when there is a change in speed true or false?
True. Motion occurs when an object changes its position relative to a reference point. A change in speed indicates a change in the rate of motion, which can result in the object moving at a different pace or direction.
Is it true that Refraction occurs when a wave strikes an object and bounces off?
false
When an object is forced to vibrate at its natural frequency resonance occurs True Or False?
True. Resonance occurs when an external force is applied to an object at its natural frequency, causing it to vibrate with increased amplitude. This can lead to the object resonating and potentially causing structural damage.
Can Once energy is applied to cause an object to vibrate a sound occurs true or false?
True. When energy is applied to make an object vibrate, it creates sound waves that we perceive as sound.
Distinguish between apparent weightlessness and true weightlessness?
Apparent weightlessness occurs when an object is in free fall, making it feel weightless due to the absence of support forces. True weightlessness occurs when an object is at a point in space where the gravitational pull is negligible, resulting in a complete absence of gravitational forces acting on the object.
When work is done energy is transferred from one object to another true or false?
True. When work is done, energy is transferred from one object to another. Work is the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
Expansion cards are installed in long narrow expansion slots on the motherboard True or False?
True
Is it true or false that balanced forces on an object cause the object the object to accelerate?
False. Balanced forces on an object do not cause the object to accelerate. Acceleration occurs when there is an unbalanced force acting on an object. Balanced forces result in no net force acting on the object, keeping it at a constant velocity or at rest.
Is it true condensation occurs when water vapor is heated?
No, condensation occurs when water vapor is cooled and changes from a gas to a liquid. Heating water vapor would cause it to remain in its gaseous state or potentially transform into steam, which is still a gas.
When the only force acting on a falling object is air resistance the object is said to be in free fall true or false?
False. When the only force acting on a falling object is air resistance, it is not considered to be in free fall. Free fall occurs when an object falls solely under the influence of gravity with no other forces acting upon it.
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
Are Expansion cards installed in long narrow expansion slots on the motherboard?
True
