2. kinetic energy: due to it being transferred through collisions
The two Health and safety risk at the scene are:
1. To deal with Chemicals.
2. To deal with Electricity.
<h3>What are Healthy and safety risk?</h3>
The healthy and safety risk at the scene or office is described as safety hazards that has to be taken when employers are working in office in some mechanical or electrical workshops.
Employers need to e follow some healthy and safety risk while working in office like:
1. Chemicals : When employees have to handle harmful or dangerous chemicals as part of their work. To safety safe the must wear protective clothing.
2. Electrics - Electrical safety is an important issue in workplace , especially where there is a risk that heavy-duty equipment might cause electric shock.
These are some safety hazards employees must follow.

Answer:
Diagram A
Explanation:
When an object is travelling in a circular path it has an acceleration called centripetal acceleration, even if it is moving with uniform speed. This acceleration is attributed to the object due to change in the direction of velocity at every instant during the motion.
The direction of the velocity of the object is tangent to the circular path at every instant and if the object beaks free of the circular motion, such as breaking of the string, then it will go in the direction tangent to the circle at that instant. Hence, the diagram that best shows the direction ball will travel is:

Answer:
2 m/s
Explanation:
Velocity is a vector quantity that is given by:
![v=\frac{d}{y}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7By%7D)
where
d is the displacement of the object (a vector indicating its change in position)
t is the time elapsed
Note that since velocity is a vector, it has both a magnitude and a direction (the same as the displacement).
For the toy train in this problem, we have:
d = 40 m (displacement)
t = 20 s (time elapsed)
So, its velocity is:
![v=\frac{40}{20}=2 m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B40%7D%7B20%7D%3D2%20m%2Fs)
It made the development of cars, trucks, and airplanes possible.
