Answer:
Explanation:
Convert mass of bullet 50g in kg
✯ Divide 50 by 1000
⟹ 50/1000
∴ 0.05 kg
My name says it all about how much help I can be to you! I have answers to so many classes. Not all, but many. Physics is one of them,
Surface salinities are higher than deepwater salinities because of the high amount of rainfall that tends to dilute the water on the surface. Higher salinities are observed to take place at "<span>about 36.7 ppt near 30° North and South" where these locations have little to no precipitation. </span>
Gravitational potential energy (GPE) is energy within an object with respect to its height. The equation of gpe is:
GPE = mgh
where:
m = mass of object
g = gravitational constant, 9.81 m/s^2
h = height
For a given gpe of 20 J, the height can be calculated as follows:
*Remember to be consistent with units. Since Joule is derived from SI units, make sure to use SI units for the other variables
GPE = 20 J = 1 (9.81) (h)
h = 2.04 meters
