What is the impulse of an object that Applies 30 N for 4 seconds?
Impulse=Force*Time interval =30*4=120Ns
What is the impulse of a baseball that is caught?
Impulse is change of momentum, which is force x time over which the force acts. Original momentum = mv, final momentum =0, so impulse is in this case mv.
Can a moving object have impulse in itself?
yes moving objects have impulse
What is a message that travels through the neuron?
An Impulse
The abrupt shift in the charge of a neuron from a negative to a positive charge is known as?
It is probably called as action potential.
What is sinus arrest?
When the Sino-atrial node fails momentarily to initiate an impulse, sinus arrest occurs. When the sino-atrial node fails momentarily to initiate an impulse, sinus arrest occurs.
Is conducting stimulus strong enough to generate a nerve impulse?
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
What monitors muscle length and sends an impulse to the spinal cord to initiate the stretch reflex?
What monitors muscle length and sends an impulse to the spinal cord to indicate the stretch reflex
What is Grendels immediate impulse when he feels the strength of Beowulfs hand?
Grendel's immediate impulse when he feels the strength of Beowulf's hand is to try and escape by fleeing back to his underwater lair.
When your nose is stuffy cannot reach nerve receptors to initiate an impulse that would result in smell or taste?
chemicals
Does the impulse cross the neuromuscular junction when a muscle contracts?
No, the impulse traveling down the axon ends at the axon terminal but causes the axon terminal to release neurotransmitters. The neurotransmitters diffuse across the synaptic cleft causing the sarcolemma of the muscle to initiate its own impulse.
What is the path of a nerve impulse from your leg to your brain and back to your leg?
A nerve impulse travels from your leg to your brain through sensory neurons. Once in the brain, the impulse is processed, and a response is generated. The response travels back to your leg through motor neurons to initiate movement or action.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
How does a single nerve impulse initiate many?
The nerve's endings are near to other nerve endings, when the potential of the potassium ion that is released is sensed by the other nerves they all might send an impulse to their other ends and the situation could be repeated.
How are the heart impulses detected?
The Pacemaker cells of the Sinoatrial Node spontaneously initiates the impulse. Without stimulation from nerve fibers or any other outside agents, the nodal cells initiate impulses that spread into the surrounding myocardium and stimulate cardiac muscle fibers to contract.
What quantity combines the strength of a force with how long the force acts on the object?
The quantity that combines the strength of a force with how long it acts on an object is called impulse. Impulse is calculated by multiplying the force by the time over which it acts on an object. It represents the change in momentum of the object.
