Answer:
1.48m
Explanation:
Info given:
mass: 0.772kg
PE = 11.2J
g = 9.81m/s^2
Using KEbottom = PEtop
PE = mgh
Plug in and solve for h (height)
11.2J = mgh
h =11.2J / mg
h = 11.2J / (0.772kg)(9.81m/s^2)
h = 1.48m
The rate of molecular motion will increase as the temperature rises. At the same temperature, an object with less massive molecules will have a faster molecular speed. Two objects with the same average kinetic energy will have the same temperature when kinetic temperature is applied.
I think that your answer would be A. because matter never just goes away in any situation, even if it gets away from you.
22 year solar cycle is characterized by a variation in the number of sunspots and a reversal of the polarity of the Sun as a whole.
What are sunspots?
Sunspots are caused by disturbances in the Sun's magnetic field welling up to the Sun's visible surface.
Sunspot are region of the earth that are more darker than other surfaces. They have a reduced temperature.
If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth.
Here, the sun's magnetic field changes polarity approximately every 11 years. So, for reversal polarity of the sun, 22 year solar cycle is characterized by a variation in the number of sunspots and a reversal of the polarity of the Sun as a whole.
