<h3>
Answer:</h3>
Velocity is 1 m/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the kiddy train is 1000 kg
- Radius of the curve is 5.0 m
- Centripetal force is 2000 N
We are required to determine the maximum speed of the train.
- Centripetal force refers to the force experienced by an object in a circular motion towards the center of a circular path.
- It is calculated by the formula;
- , where m is the mass, v is the velocity and r is the radius of the circular path.
- Therefore, using the formula we can find the maximum speed.
Therefore, the maximum speed of the train is 1 m/s
Atoms with neutrons, protons, and electrons. Only the neutron has no electrical charge; protons and electrons are the other particles that are electrically charged.
<h3>What do you know about atoms? explain.</h3>
The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass. The electric charges of the protons are positive, those of the electrons are negative, and those of the neutrons are zero. The atom is electrically neutral if the number of protons and electrons is equal.

Answer: -
3-Ethyl-N,N-dimethylbenzamide.
Explanation: -
In the first step the nitrogen lone pair attacks the carbonyl carbon.
Then a OH becomes water molecule by protonation and leaves.
Final step involves proton loss to form amide.
Crack comes in the form of a white crystal rock; while cocaine comes in the form of a white powder. Cocaine is a type of illegal drug derived from coca leaves. This drug distorts the body’s sense of movement and pleasure as well as gives off feelings of euphoria and energizes the body. Cocaine can be snorted or injected. Crack, a freebase form of cocaine, is smoked.
Yea ma’am yea sir I am in the process and I’m just getting my car back from work I just saw it and when I got back I went to the doctor for the day so Lillian
