What is one example of negative acceleration?
A car slowing down when the brakes are applied.
What must cause acceleration when a car is moving a constant speed and why?
Acceleration is scientifically defined as a change in velocity, not an increase in speed. Thus slowing down, speeding up, or changing direction are all forms of accelerating. If one is moving at a constant speed, then the only way to accelerate would be to change direction.
Why does your car jerk when slowing down?
it jerks because if it is automatic it is goin down a gear
When final velocity is less then initial velocity of an object the acceleration is negative?
yes, many answers in applied maths come out as negative, it just means that the force or object is slowing down or reversing. in this case there is a negative acceleration as its slowing down
Moving at a less than usual speed?
for my science worksheet it is slower, but it is basically slow and, or slowing down.
What is the slowing down of neutrons to increase the probability of their absorption by the Atoms in uranium called?
neutron moderation
What is the slowing down of neutrons to increase their probability of absorption by the atoms in uranium 235 called?
Neutron moderation
What is neutron absorption?
Neutron absorption is the process by which a neutron is captured by an atomic nucleus, resulting in the formation of a new isotope or activation of the nucleus. This phenomenon plays a crucial role in nuclear reactions, nuclear power plants, and nuclear weapons.
Does graphite slow neutrons down?
Yes, graphite can slow down neutrons through a process called moderation. Graphite has a lower neutron absorption cross-section compared to other materials, allowing neutrons to penetrate and interact with the carbon atoms, effectively slowing down the neutrons.
Which type of food is most effective in slowing down the alcohol-absorption?
high fat
hydrogenic materials are used as moderators in nuclear reactors to slow down the neutrons Why?
Hydrogenic materials, like water or heavy water, are used as moderators in nuclear reactors because they are effective at slowing down neutrons through elastic scattering. Slowing down neutrons is important to make them more likely to interact with other nuclei, initiating a chain reaction in the reactor. Hydrogen atoms in these materials have a similar mass to neutrons, making them efficient at transferring kinetic energy and slowing down the neutrons.
How moderators reduce speed of neutrons?
Moderators reduce the speed of neutrons by using materials that have a lower atomic mass, such as water or graphite. When fast neutrons interact with these lighter atoms, they transfer some kinetic energy, slowing down in the process. This process is important in nuclear reactors to control the speed of neutrons and facilitate their interaction with fuel atoms.
Which material is used in controlling chain reaction in nuclear reactor?
The material used to slow down high-speed neutrons in a reactor is called the moderator. The moderator in a pressurized water reactor is the water, which is the main coolant. Collisions between the neutron and hydrogen nuclei (protons) slow the neutron down (thermalizing it) and increasing the probability that it will be absorbed by another fissionable atom. That makes the chain go, it maintains the chain reaction. Slowing down neutrons does NOTslow down the process of nuclear fission. If anything, it maintains it or speeds it up because slower moving neutrons have a higher probability of being absorbed and continuing or building the chain reaction. A link is provided.
The term deceleration means?
Deceleration refers to the decrease in speed or slowing down of an object over time. It is the opposite of acceleration, which involves an increase in speed.
In nuclear reactor heavy water is used as?
In a nuclear reactor, heavy water is used as a neutron moderator. It slows down neutrons produced during nuclear fission to enhance the probability of additional fission reactions. Heavy water, with its extra neutron, is more effective at slowing down neutrons compared to regular (light) water.
What is the element found in the control rods of most nuclear reactors?
The element found in the control rods of most nuclear reactors is usually made of a material called boron. Boron is used because it has a high neutron absorption rate, which helps control the nuclear fission process by absorbing excess neutrons and slowing down the reaction.
What type of food is most effective in slowing down the alcohol-absorption process?
high fat
