A porcupine would be the answer I think
Answer: the entropy and entalpy of the system will increase
Explanation: adding energy to the system will cause the molecules within the jar to absorb more energy, this excitation will bring about more movement of the molecules and more collision between molecules. Also, the molecules will try to move further apart from themselves with increased degree of randomness.
The correct answer is C. None of them are struck by hazards but rather caught in or between hazards.
A struck by hazard is when an object such as a flying object, falling object, swinging object or rolling object accidentally comes into contact with a person and impacts the person with another object or piece of equipment. A caught in or between injury is similar to a struck by hazard but they are created more as a result of a crushing injury between two objects such as being pulled into or caught in machinery and equipment or being compressed or crushed between rolling, sliding or shifting objects.
C. It decreases in wave speed.
<span>Period of a wave is the time needed for one complete cycle of vibration to pass a given point. Frequency and period have a reciprocal relationship. Frequency can be similarly thought of as speed of a wave.</span>
