How are distance and time related when describing motion?

Physics
1 answer:
Bingel [31]3 years ago
3 0
an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is appro
Alexxx [7]

Explanation:

It is given that,

Radius of the circular orbit, r=0.53\times 10^{-10}\ m  

Speed of the electron, v=2.2\times 10^6\ m/s

Mass of the electron, m=9.1\times 10^{-31}\ kg

(a) The force acting on the electron is centripetal force. Its formula is given by :

F=\dfrac{mv^2}{r}

F=\dfrac{9.1\times 10^{-31}\times (2.2\times 10^6)^2}{0.53\times 10^{-10}}  

F=8.31\times 10^{-8}\ N

(b) The centripetal acceleration of the electron is given by :

a=\dfrac{v^2}{r}

a=\dfrac{(2.2\times 10^6)^2}{0.53\times 10^{-10}}

a=9.13\times 10^{22}\ m/s^2

Hence, this is the required solution.

What is the work energy transfer equation?
rosijanka [135]

Answer:

The equation used to calculate the work done is: work done = force × distance. W = F × d. This is when: work done (W) is measured in joules (J)
