In physics, there are empirical values for common important parameters. For example, the speed of sound is equal to 340 meters per second. Unlike the speed of light, the speed of sound is dependent on temperature and pressure. But in standard room conditions, the speed is 340 m/s. Using this value of speed, we can find the depth given the time. You should also note that the distance the echo travels is exactly the same distance that object travelled. Therefore,
Distance = 340 m/s * 6 seconds
Distance = 2,040 meters deep
Answer:
Explanation:
D.
Thermodynamics is the study of how different types of energy is transferred through the chemical systems
Answer:
You are moving away from him at 90% the speed of light. Joan is moving away from him at as speed that is faster than 90% of the speed of light but slower than the whole speed of light.
Explanation:
According to relativity, you cannot exceed the speed of light.
Answer: a. Regularly, you rub your hands for warmth.
b. Some examples are friction from electricity going through a wire or friction from rubbing your hand together.
c. Without friction, we would fall every time we walked. Because there is friction, we can walk normally. Another example is a ball moving across the field. Without friction, the ball would not slow down.
Explanation:
Overall, friction is important to us because we depend on it.
