Answer:
A. Approximately 2000 times the mass of an electron.
Step-by-step explanation:
Lets do the division:
Mass of neutron / mass of electron
2 × 10^-24 / 9 x 10^-28
= 0.222 x (10^(-24 - (-28))
= 0.2222... x 10^4
= 2222.
Answer:
The equation of this line would be y = -1/2x + 1
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we need to solve the original equation for y.
2x + 4y = 16
4y = -2x + 16
y = -1/2x + 4
The original slope (the coefficient of x) is -1/2, which means the new slope will also be -1/2 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 2 = -1/2(x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1
Answer:
Maybe the answer must be 90°
The distance formula to help you solve this is √(x2-x1)∧2(y2-y1)∧2
After solving this you should get 28 as your final answer.
