Atomic mass (z) - atomic number / # of protons (n) = # of neutrons:
151-54=97
You can easily tell what element X is. With an atomic number of 54, the element is the noble gas Xenon (Xe).
A scientific claim<span> can be a prediction that something will happen, based on a scientific theory or a hypothesis. A valid scientific claim is when t</span><span>he claim is supported by at least ten scientists in addition to the original researcher. Hope this answers the question. Have a nice day.</span>
Answer: *The inner planet that has two moons is Mars * the only planet in the Solar System with clockwise rotation is Venus * The surface of Mercury is covered with ancient magma ( which is similar to the spews of volcanoes on Earth as well) * The planet that is closest to Earth is Mercury * Venus has more volcanoes than any other planet * Earth's moon formed when a(n) can sometimes be called the Big Splash or can be called the Theia impact (Luna the moon formed from the ejecta of the collision between the Proto- Earth and Mars sized planet) * Mars is called the red planet because it's soil contains the element iron oxide ( which is the compound that gives blood and rust hue)
Explanation: Hope this helped :)
Answer:
Explanation:
Since the surface is frictionless therefore there will be no friction force on block but there will be weight of block which we can divide in to two components i.e. mgcosθ &mgsinθ which is perpendicular and parallel to the surface respectively.
In response to mgcosθ ramp will apply a normal force to the block which will be of equal magnitude to that of mgcosθ.
Therefore Ramp will apply a Force of mgcosθ on block where m is the mass of block.
Temperature can be described as an indirect measure of heat energy
So therefore your answer should be letter C
