<u>Substance</u><u>:</u><u>-</u>
- A substance is matter which has a specific composition and specific properties.
Answer:
D All
Explanation:
Mechanical and electromagnetic waves both carry energy. The mechanical wave via the motion/vibration of particles, and the electromagnetic via vibration of the electric and magnetic fields.
We know of interference patterns of light (electromagnetic interference), as well as interference of mechanical waves of water generating typical patterns.
Both, electromagnetic and mechanical waves go through the process of reflection when hitting a barrier (mirror for example in the case of light, and a solid wall for example in the case of water waves.
So the correct answer is "All of the above"
Answer:
Explanation: the tempure range is 1,400
Given that,
Mass of a water balloon, m = 1 kg
It comes downward an experience a 4.9 N air resistance as it approaches the ground.
To find,
The acceleration of the water balloon when it experiences this air resistance.
Solution,
Let the acceleration be a.
The net force acting on it will be :
The force is also given by :
F = ma
So, the acceleration of the water balloon is .
