It deals with skin diseases
Answer:
(a) 2.3 x 10^-12 N
(b) 1.6 x 10^5 m/s
Explanation:
q1 = 1.6 x 10^-19 C
q2 = 1.6 x 10^-19 C
r = 1 x 10^-8 m
(a) the electrostatic force is given by
F = K q1 x q2 / r^2
F = ( 9 x 10^9 x 1.6 x 10^-19 x 1.6 x 10^-19) / (1 x 10-^-8)^2
F = 2.3 x 10^-12 N
The force is attractive in nature because the nature of charge on electron and proton s opposite to each other.
(b) The electrostatic force is balanced by the centripetal force actig on the electron.
F = mv^2 / r
where, r be the radius of orbit and v be the velocity of electron in the orbit.
2.3 x 10^-12 = (9.1 x 10^-31 x v^2) / (1 x 10^-8)
v = 1.6 x 10^5 m/s
Answer:
0.166666667
Explanation:
900 divided by 150
hope dis answer was to use to you'd
automated message: the answer is yes two shirts and B and the yes two shirts and B and I am a a fraction with numerator then you will go to a new one w a fraction for better etc and 2 hope you had to be one more thing I need to see the attachment
The astronauts, the ISS itself and other objects in Earth orbit aren't floating, they are actually falling. ... So, as they accelerate towards the Earth, the Earth curves away beneath them and they never get any closer. Since the astronauts have the same acceleration as the space station, they feel weightless.
( can I please get the brainliest, thanks)
1. Has to be a very large bathtub or very, very small supertanker
2. The car hit harder because the bug is not going anywhere near the same speed as the car, therefore it is not exerting the same force.
3. It's so fast it's hard to put a number on it and and it depends on the think Es of wire, distance from wall, and which type of T.V. (because if it requires less electricity then the electrons will travel slower)
4. The ball being thrown, because when and object is thrown and then falls, it always falls at a greater speed then those just being dropped.
