Is impulse conserved in collision?
In collisions, impulse is not always conserved because impulse depends on the change in momentum of the objects involved. If external forces are acting during the collision, then impulse may not be conserved. However, in ideal situations like perfectly elastic collisions where no external forces are present, the total impulse before and after the collision would be the same.
What impulse would occur when the same force of 10 N acts on the cart for twice the time?
The impulse will be twice as large, at 20 Ns, due to the force acting for a longer duration. Impulse is the product of force and time, so increasing the time the force is applied increases the impulse.
When impulse will be zero?
An impulse will be zero when the force acting on an object is zero or when the force is applied for a very short period of time. In other words, when the change in momentum of an object is zero, the impulse will also be zero.
If a box is hit with a 280 N force for .08 seconds. What is the impulse on the box?
The impulse on the box is equal to the force applied multiplied by the time duration it was applied for. In this case, the impulse would be 280 N * 0.08 s = 22.4 Ns.
A 2,500-kg car hits a fence with a force of 400 N, and the collision takes one second What is the magnitude of its impulse?
The impulse experienced by the car is equal to the change in momentum. The formula for impulse is force multiplied by time, so the impulse would be 400 N * 1 s = 400 Ns.
What are three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.

What kind of impulse carries impulses toward the spinal cord and brain?
A reflex. Reflexes are processed by the spinal cord in order to provide a quicker reaction than would be achieved if the signal travelled all the way to the brain and back.
How would you describe jacks violent reaction?
he dies
How long would it take for an impulse to travel through a reflex arc?
The time it takes for an impulse to travel through a reflex arc typically ranges from about 20 to 50 milliseconds. This duration can vary based on factors such as the length of the reflex arc and the type of nerve fibers involved. Generally, faster impulses travel along myelinated fibers, while slower impulses travel along unmyelinated fibers. Overall, the speed is quick enough to allow for rapid reflexive responses to stimuli.
Is the sudden withdrawal of ones hand from a hot stove a reflex?
The reflex action of burning your hand would be jerking your hand away from the source of the heat
If a bee sting on the right thigh causes a quick involuntary reaction of the right arm what kind of reflex occured?
The bee sting caused a crossed extensor reflex. This reflex involves the simultaneous contraction of the muscles in the right arm and the relaxation of the muscles in the left arm in response to the pain stimulus on the right thigh, helping to quickly remove the affected limb from danger.
What word would you use to describe the reaction water uses to break apart large molecules?
monomer reaction
What would would you use to describe HgO in the reaction that Lavoisier used to show conservation of mass?
Product
How would you describe a hexagon?
you can describe the hexagon by: how many acute angles, obtuse angles, and reflex angles cancave polygon or convex polygon how many sides does it have irregular no line of symmetry or line of symmetry
What term is define as new substance formed chemical reaction?
The term used to describe a new substance formed from a chemical reaction would be "product."
Enthalpy of a reaction is -394 kJ mol How would you describe the reaction?
The reaction is exothermic since the enthalpy change is negative (-394 kJ/mol), indicating that it releases energy to the surroundings.
