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
Is there an all of the above box? these all seem right
Answer:
The electrical potential energy is 0.027 Joules.
Explanation:
The values from the question are
charge (q) =
Electric Field strength (E) =
Distance from source (d) = 0.030 m
Now the formula for the electrical potential energy (U) is given by
So now insert the values to find the answer
On further solving
WITHOUT air resistance . . . like on the moon, or in a tank with all
the air removed from it . . . a feather, an orange, and a watermelon
will all fall at the same rate.
So will a piece of tissue, a mosquito, school bus, a rock, and a cruise
ship.
If you drop them all at the same time, then they will all hit the ground
at the same time.
