Answer:
Radius of the outer most dark fringe is 2.65 cm
Solution:
As per the question:
Radius of curvature of the glass, r = 10.8 m
No. of dark fringes, n = 100
Wavelength of light,
Now,
To calculate the radius R of the outermost ring:
Radius of the dark fringe of nth order is given by:
Answer:
a) Magnitude = 1.03 m/s², Direction: south
b)
Explanation:
a) The magnitude and direction of the acceleration can be calculated using the following equation:
(1)
Where:
: is the final speed = 9.40 m/s
: is the initial speed = 13.0 m/s
t: is the time = 3.50 s
Solving equation (1) for a, we have:
Hence, the magnitude of the acceleration is 1.03 m/s² and the direction of the bird's acceleration is the opposite of the initial velocity direction, which means that the bird is decelerating.
b) The final velocity of the bird can be found using the same equation 1:
Therefore, the bird’s velocity after an additional 1.20 s has elapsed is 8.16 m/s.
I hope it helps you!
Answer:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions
Answer:
Inertia relates directly to an object's <em>mass</em>. It is its inherent property and expresses how much force is needed to bring the object to a certain level of acceleration. It is the sole factor.
Momentum relates proportionally to two factors: <em>mass</em> and <em>velocity</em>. As such, momentum is not an inherent property of an object but a measure dependent on it current velocity, in addition to its mass.
Answer:
The ball will take path 'c' after colliding with the bumper.
Explanation:
If the ball is made not to spin, then it will deflect along path b
From above, If the ball spin clockwise and the point of the ball is in contact with the edge of the table stops for a moment during the collision.
Due to the angular momentum of the ball, the ball would be forced to move towards the left. The rotational velocity will be initially downward because cue made the ball to rotate in the clockwise direction. For the ball to spin less there will be some torque acting on the ball which will cause acceleration in the counterclockwise direction.
The edge of the table produce the required acceleration. i.e a force have to be exerted by the edge of the table on the ball with a component to the left as viewed from the player's perspective.
Therefore, the ball will take path'c' after colliding with the bumper.
