Answer:
c. slow motion is achieved by filming at a slower rate than is normal
Explanation:
Slow motion is achieved by filming at a faster frame rate and playing the video in a slower frame rate. When filming is done at a slower frame rate and played at a faster frame rate this is used to make a time lapse video.
Suppose you film something at 240000 frames per second and play it at 24 frames per second then the video will be (240000/24) 10000 times slower.
Answer: The recently discovered Eris orbits the Sun every 557 years. ... 67.69 AU; since the average distance for Pluto from the Sun is 39.3 AU then the distance is nearly twice.
Explanation:
Answer: The force needed is 140.22 Newtons.
Explanation:
The key assumption in this problem is that the acceleration is constant along the path of the barrel bringing the pellet from velocity 0 to 155 m/s. This means the velocity is linearly increasing in time.
The force exerted on the pellet is
F = m a
In order to calculate the acceleration, given the displacement d,
we will need to determine the time t it took for the pellet to make the distance through the barrel of 0.6m. That time can be determined using the average velocity of the pellet while traveling through the barrel. Since the velocity is a linear function of time, as mentioned above, the average is easy to calculate as:
This value can be used to determine the time for the pellet through the barrel:
Finally, we can use the above to calculate the force:
