Answer:
h = 24.11 m
Explanation:
Given that,
The potential energy of the snowball is 520 J
The mass of the snowball is 2.2 kg
We need to find the height of the hill. The potential energy of an object is given by the formula as follows :
g is acceleration due to gravity
h is height of the hill
So, the height of the hill is 24.11 m.
Answer:
d) all of the above
Explanation:
the speed, velocity, and acceleration all changes to 0 due to no motion.
That particular group of elements is reffered to as the "Noble Gasses"--a title that comes from the fact that these gases are very "secure" and don't mix well with other elements.
Kinetic energy, KE, is modeled by the formula
, where m is the mass in kg and v is the velocity in m/s.
In this scenario, mass and one-half are constant but the velocity changes.
You can see that by squaring twice the velocity, that is equal to four times the original KE. Therefore, the answer is 4k.
Explanation:
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers
