Answer:
Explanation:
A multistage rock is also known as a step rocket and it is a form of vehicle that can use more than a rocket stage. The rocket stage typically contains propellant as well as its engine. The final speed of the rocket can be estimated using the equation below:
Therefore, the maximum speed of the rocket is
Answer and Explanation:
a. An oxygen-filled balloon is not able to float in the air, because the oxygen inside the balloon is of the same density, that is, the same "weight" as the oxygen outside the balloon and present in the atmosphere. The balloon can only float if the gas inside it is less dense than atmospheric oxygen. Helium gas is less dense than atmospheric gas, so if a balloon is filled with helium gas, that balloon will be able to float because of the difference in density.
b. The ship is able to float in the water because its steel construction is hollow and full of air. This makes the average density of this ship less than the density of water, which makes the ship lighter than water and for this reason, this ship is able to float. In addition, the ship is partially immersed, allowing the weight of the ship on the water to counteract the buoyant force that the water promotes on the ship. Weight and buoyant are two opposing forces that keep the ship afloat.
That is actually correct because some people can be influence on how they get treated wether it's getting a wooping at home or being rejected by a group of kids some people have low self of steem and really want to fit in
Answer: Neurotransmitters are being produced by neuron and stored in vesicles.
Explanation:
Neurotransmitters are secreted into the synaptic gap by exocytosis process, where the vesicles membranes fuse with the presynaptic button. The synaptic gap is usually in the order of 0.02 micron.
Several neurotransmitters include Acetylcholine, Dopamine, GABA (gamma-aminobutyric acid), Glutamate, Norepinephrine, and Serotonin.
It should have 1 or even less. Modern seat-belts have almost no slack when the sensors detect that the seat-belt has been rapidly expanded. This is done so to hold you in place and prevent you from slamming against the seat-belt if you have a collision at high speeds.
