euphemism oxymoron dramatic irony Excerpts Literary Devices In this story I read, Karen assumes her sister Mira is flushed with joy at learning of her eldest son's imminent return from the battle front. But the narrator makes it clear that Mira is beginning to wonder about the anti-war letters she recently sent to the president. "Marla, don't tease Sandy about how much she's been eating lately. For all you know she might have another bun in the oven." Unsure if he was really safe from the tiger he spotted earlier, Johan's heart beat quickly as he crouched and listened to the screaming silence of the forest. I rights reserved
It helps you understand the concept of what you are predicting
1. What is the force of the marble?
For an object near the surface of the earth, the gravitational force acting upon the object is given by:
F = mg
F is the gravitational force, m is the object's mass, and g is the acceleration of objects due to earth's gravity.
Given values:
m = 0.025kg, g = 9.8m/s²
Plug in the given values and solve for F:
F = 0.025×9.8
F = 0.25N
2. What is the marble's potential energy at the start of its fall?
The gravitational potential energy of an object near the earth's surface is given by:
PE = mgh
PE is the potential energy, m is the object's mass, g is the acceleration of objects due to earth's gravity, and h is the object's relative height.
new given values:
h = 0.08m
Since F = mg, you can simply multiply F×h to get PE. Use the result from question 1:
PE = F×h
PE = 0.25×0.08
PE = 0.02J
From the information given,
diameter of ornament = 8
radius = diameter/2 = 8/2
radius of curvature, r = 4
Recall,
focal length, f = radius of curvature/2 = 4/2
f = 2
Recall,
magnification = image d
Elements are identified by the nuclei of the atoms of which they are made. For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. ... Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. This is how they are formed
