The speed of a chemical reaction is affected by four factors: enzymes, concentration, temperature, particle size, and the presence of a suitable catalyst.

Direction of force also towards centre
True, because people should reach their full potential within themselves and human psychologist should help those that need help to reach it.
Answer: The answer is in the figure attached.
Explanation:
The Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the <u>International System of Units</u> is the Joule (J). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
However, in the British Engineering and Gravitational Systems its unit is Foot-pound (ft-lb). Where
Now, when the applied force is constant and the direction of the force and the direction of the movement (traveled distance) are parallel, the equation to calculate it is:
So, taking into account the explanation above, the attached table shows the Work done for each situation.
<span>Answer:
Fn is the force acting on the nut and d is the distance of the nut from the pivot.
F is the applied force at one end and D is the distance of the end from the pivot.
F.D = Fn*d</span>
