Except:they are safe for all organisms except insect pest
Answer:There is no change in identity of the substance and we can visually see a substance being drawn into wires. Hence ductility is not a chemical property, it is a physical property. Some examples of ductile materials, include metals such as copper, aluminium, silver, gold, etc.

Answer:</h3>
Acceleration of the cyclist: 2.67 m/s²
The acceleration of the cyclist is lower than that of the car.
<h3>
Explanation:</h3>
- Acceleration refers to the rate of change in velocity of a body in motion.
- It is calculated by; dividing the change in velocity by time.
- Acceleration = (Final velocity - Initial velocity) ÷ time
In this case;
For the cyclist;
Initial velocity = 0 m/s
Final velocity = 8 m/s
time = 3 seconds
Therefore;
Acceleration = (8 m/s - 0 m/s) ÷ 3 seconds
= 2.67 m/s²
For the car;
- Initial velocity = 0 m/s
- Final velocity = 30 m/s
- Time = 8 seconds
Therefore;
Acceleration = ( 30 m/s - 0 m/s) ÷ 8 seconds
= 3.75 m/s²
The acceleration of the cyclist is lower than that of the car.
A- 5000 decilitres
B- 42000
