Answer:
e. The impulse exerted by the floor
Explanation:
a. The momentum just before colliding with the floor.
will be identical because they have the same mass and are falling the same distance so will have the same velocity. p = mΔv, v = √(2gh)
b. The amount of time in contact with the floor.
a component of impulse, but not the entire story. Ball B could have a longer contact time, but a smaller average force. p = FΔt
c. The kinetic energy just before colliding with the floor.
will be identical because they have the same mass and are falling the same distance so will have the same velocity. KE = ½mv², v = √(2gh)
d. The average force exerted by the floor
a component of impulse, but not the entire story. ball B could have a larger average force but a shorter period of action. p = FΔt
Answer:
T'=46.6 K
Explanation:
Let T be the temperature of a hot reservoir, T' be the temperature of cold reservoir.
For a Carnot's engine, efficiency can be calculated as follows:
Where, W is the amount of work done, Q is the amount of heat extracted from the hot reservoir.
Substitute the values: W= 8.0 J
Q = 10.0 J
T = 233 K
Thus, the temperature of the cold reservoir is 46.6 K.
I don't know about hard to make, but it's impossible to make a mechanical wave transmit energy through a vacuum.
The activity occurring at an axon terminal involves the following labelled 1 - 6:
- synaptic vesicles
- synapse
- motor end plates (neurotransmitter receptor)
- calcium channel
- neurotransmitters
- axon
The transmission of nerve impulses between neurons, muscles cells or glands is known as nervous transmissions.
Axons are long slender projections of neurons which are responsible for nervous transmission.
Neurons use both electrochemical signals and chemicals known as neurotransmitters to transmit impulses from one neuron to the next.
The junction between two neurons or an effector cell is known as a synapse.
Neurotransmitters are packaged into synaptic vesicles at the axon end. When electrical signal reaches the end of the axon, influx of calcium ions through the calcium channel cause the the synaptic vessels to fuse with the presynaptic membrane and then release their contents into the synaptic cleft or space.
The neurotransmitters released then bind to the motor end plate resulting in another impulse transmission along the second neuron or an action by effector cells.
