Answer:
0.79 cm
Explanation:
The computation is shown below:-
Particle acceleration is
We will take d which indicates distance as from the negative plate, so the travel by proton is 0.800 cm - d at the same time
After solving the equation we will get 0.79 cm from the negative plate.
Therefore it is 0.79 cm far from the negative pate i.e the point at which the electron and proton pass each other
Answer:
0.99 s
Explanation:
The period of a simple pendulum is given by:
where
L is the length of the pendulum
g is the acceleration due to gravity
In this problem, we have
Substituting into the equation, we find the period:
Answer: B
Explanation: The straight line shows the theoretical average of the actual velocity and the curved line show that it is less than the average velocity of the object within 6 seconds.
straight line:
3. 3,80
6. 6,160
curved line:
- 1,2
- 2,17
- 3,32
- 4,60
- 5,100
- 6,160
A.K.A.-- the only place where the straight line and the curved line meet at is only at coordinate 6,160.
Answer:
15.0 m/s
Explanation:
When elastic collision occurs, the final velocities, v of the bodies are obtained by
Where u and m denote initial velocities and mass while the subscripts 1 and 2 are for tennis ball and the other ball
Substituting 0.311 for mass of tennis, 0.0570 for mass of the other ball, 30.3 m/s for velocity of tennis ball and -19.2 m/s
velocity of the physics instructor with respect to bus
acceleration of the bus is given as
acceleration of instructor with respect to bus is given as
now the maximum distance that instructor will move with respect to bus is given as
so the position of the instructor with respect to door is exceed by
so it will be moved maximum by 3 m distance
