The normal force acting on the legs of the table is 175 N
The weight of the books is the force exerted by the books on the table, and it is given as:
The force exerted by the table is given as:
The parameters above imply that:
- The table and the books are stationary,
- The force exerted by both act in the same downward direction.
So, the normal force acting on the legs of the table is calculated as follows:
Substitute known values
Hence, the normal force acting on the legs of the table is 175 N

Swing it backwards and forwards, because according to newtons law, every action force has an opposite and equal reaction force. When you swing it one way, the jet pack will be pushed to other way, so when this motion is completed as many times/ with enough energy, the person will reach the station
The number of different combinations of these items that you can make if you choose four (4) toppings is equal to 1.
<h3>How to calculate the combinations of these items.</h3>
In order to determine the combinations of these items that this person can make, we would use this mathematical model known as combination.
Mathematically, combination is calculated by using this mathematical equation:
<u>Where:</u>
- n is the total number of items.
- r is the number of times of choosing items.
<u>Given the following data:</u>
Let us assume you'll choose four (4) toppings.
Substituting the given parameters into the formula, we have;
⁴C₄ = 4/4
⁴C₄ = 1.

Answer: Rational choice theory is based on the fundamental tenets of classical criminology, which hold that people freely choose their behaviour and are motivated by the avoidance of pain and the pursuit of pleasure. Individuals evaluate their choice of actions in accordance with each option's ability to produce advantage, pleasure and happiness. Rational choice provides a micro perspective on why individual offenders decide to commit specific crimes; people choose to engage in crime because it can be rewarding, easy, satisfying and fun. The central premise of this theory is that people are rational beings whose behaviour can be controlled or modified by a fear of punishment. In this way, it is believed offenders can be persuaded to desist from offending by intensifying their fear of punishment. In terms of setting the quantum of punishment, according to this theory, sanctions should be limited to what is necessary to deter people from choosing crime (Siegel and McCormick, 2006).
Rational choice is premised on a utilitarian belief that actions are based on a conscious evaluation of the utility of acting in a certain way. This perspective assumes that crime is a personal choice, the result of individual decision-making processes. This means that individuals are responsible for their choices and thus individual offenders are subject to blame for their criminality. In terms of offending, rational choice posits that offenders weigh the potential benefits and consequences associated with committing an offence and then make a rational choice on the basis of this evaluation. Therefore, before committing a crime, the reasoning criminal weighs the chances of getting caught, the severity of the expected penalty and the value to be gained by committing the act. This means that if offenders perceive the costs to be too high, the act to be too risky, or the payoff to be too small, they will choose to not engage in the act.
The tenets of this theory are based on a number of assumptions about the decision-making process and behavioural motivations. It is held that people decide to commit crime after careful consideration of the costs and benefits of behaving in a certain manner. This involves considering both personal factors, which may include a need for money, revenge, or entertainment, and situational factors such as the target/victim’s vulnerability and the presence of witnesses, guardians, or the police. Rational choice focuses on the opportunity to commit crime and on how criminal choices are structured by the social environment and situational variables.
