The observer can conclude that the sound is moving away from them and that its speed is increasing.
The light coming out of a concave lens will never meet.
So, the answer is A. will never meet.
Happy Studying! ^^
Answer:
The cylinder’s total kinetic energy is 1.918 J.
Explanation:
Given that,
Mass = 4.1 kg
Radius = 0.057 m
Speed = 0.79 m/s
We need to calculate the linear kinetic energy
Using formula of linear kinetic energy



We need to calculate the rotational kinetic energy




The total kinetic energy is given by



Hence, The cylinder’s total kinetic energy is 1.918 J.
Answer:
Sunlight
Explanation:
Sunlight is necessary in photosynthesis, which provides the main form of energy that plants use, glucose. Water (H2O) is also important because it forms part of glucose and is necessary in the process.
