On the Newtonian theory of gravity, gravitation affects anything with mass. Assuming that none of the answer choices is the only thing that exists in the universe, all of the answer choices are subject to the law of universal gravitation (hence “universal”).
Satellites, water, frogs, and stars all have mass as they are all composed of matter. Thus, all four answer choices should be circled.
Explanation:
Formula to calculate the electric field of the sheet is as follows.
E = 
And, expression for magnitude of force exerted on the electron is as follows.
F = Eq
So, work done by the force on electron is as follows.
W = Fs
where, s = distance of electron from its initial position
= (0.570 - 0.06) m
= 0.51 m
First, we will calculate the electric field as follows.
E =
= 
= 0.259 N/C
Now, force will be calculated as follows.
F = Eq
= 
= 
Now, work done will be as follows.
W = Fs
= 
= 
Thus, we can conclude that work done on the electron by the electric field of the sheet is .
Answer:
The state of matter in Gas state has the greatest amount of particle movement.
Explanation:
Matter is classified generally in three states of matter and that is solid state, liquid state and gas state. So each state has its own properties and arrangement of atoms. If we consider solid state, the atoms will be bonded very close to each other and thus the movement of particles or atoms are very much restricted in a solid state. If we consider liquid state, then the atoms will be somewhat loosely bonded compared to solid and so the particles can be somewhat flexible to move from their original position. While for gaseous state, they are the most loosely connected state and so the atoms can move as freely as possible with no restrictions. Thus the gas state of matter has the greatest amount of particle movement among the given choices.
Answer:
Explanation:
a.) hypermetropia is the reason for his problem
b.)Image is formed farther from the near point
c.) defect is corrected by convex lens
Ah hah ! That depends on where he weighs 1250N, because
weight depends not only on mass but also on the local gravity.
So the same mass can have different weights in different places,
and the same weight can indicate different mass in different places.
Weight = (mass) x (acceleration of gravity) .
Note: 1250N is almost exactly 281 pounds.
-- If he weighs 1250N on Mars, then his mass is 336.8 kg.
-- If he weighs 1250N on Earth, then his mass is 127.5 kg.
-- If he weighs 1250N on the Moon, then his mass is 770.2 kg.
