Answer:
Explanation:Before to Rutherford, the accepted model for the atom was Thomson's model:
The atoms were a positive sphere, with electrons occupying space in it".
This was called the "plum pudding model".
Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.
Then the correct option is that the atom is mostly empty space.
<span>Presuming that the gas behaves like an ideal gas:
Volume in cubic meter V= 59.6x 0.001= 0.0596 mÂł
n=3.01 mol
Temperature in Kelvin T=44.9+273.15=318.05 K
R= 8.413 J/ mol K
The ideal gas law:
PxV= nxRxT
Substituting the give information from the question into the ideal gas law:
P= 3.01 mol x 8.413 J/mol k x 318.05 K / 0.0596= 133544.392 Pa
1351.3458 Pa / 101325 Pa/ atm = 1.3179806 atm</span>
Scalar is a quantity such as mass or length that is completely determined by its own magnitude and has no direction. Therefore, your answer is Speed.
Answer:
A. 2.83 m/s
B. 39.55 degrees north of east
Explanation:
The velocity of the ball relative to the ground is the sum vectors of velocity of the ball relative to Mia and the velocity of Mia relative to the ground
If we take north east as positive direction then
Velocity vector of the ball relative to Mia is
Velocity of Mia relative to gorund is
<0, 5.3>
So velocity of the ball relative to the ground is
<1.8, -3.12> + <0, 5.3> = <1.8, 2.18>
Its magnitude is:
m/s
Its direction is
north of east
The correct answer is A. Lumen
This is the so called energy of light measurement. Other mentioned measurements are used for different things such as measuring light over an area of space or similar.
