Answer: the waves probably hits an open cavity
Explanation:
Sound waves transfers energy in form of vibration through water,the speed of sound is greatest in solids followed by liquids and gases,for we to observe such a reduction from 4000m/s to 1500m/s that means it sound had been transmitted through air like open cavity seen in intrusive rock beneath the earth.
Nuclear energy comes from the binding energy that is stored in the centre of an atom and holds it together. To release the energy, the atom has to be split into smaller atoms. This process is called fission. Answer is: false. Correct answer is nuclear energy.
Answer:a) The bullet will miss the monkey because the monkey falls down while the bullet speeds straight forward.
Explanation: The bullet keeps as it aim( the monkey) unless it is redirected by an external force that could redirect it. Hence, the bullet speeds straight forward.
The object's mass is irrelevant.
The acceleration due to Earth's gravity is inversely proportional to the square of the object's distance from the center of the Earth.
