<span>If both surfaces are convex the lens is thicker at its center than its edges. A lens with one surface convex and one concave is called meniscus. Some lenses change the direction of the rays enough to cause the rays in a bundle to emerge convergent, that is, converging toward a common point. Whatever the mix of surfaces, if the lens is thicker at its center than its edges it is called a converging lens (having positive focal length). If it is thinner at its center than its edges it is called diverging (having negative focal length).</span>
Answer:
2 m/s and -2 m/s
Explanation:
The object travels with an angle of
60.0°
with the positive direction of the y-axis: this means that it lies either in the 1st quadrant (positive x) or in the 2nd quadrant (negative x).
If it lies in the 1st quadrant, the value of vx (component of v along x direction) is:
If it lies in the 2nd quadrant, the value of vx (component of v along x direction) is:
Answer:
2 m/s
Explanation:
From the conservation of momentum, the initial momentum of the system must be equal to the final momentum of the system.
Let the 10.00 kg mass be and the 12.0 kg mass be . When they collide and stick, they have a combined mass of .
Momentum is given by . Set up the following equation:
, where is the desired final velocity of the masses.
Call the right direction positive. To indicate the 12.0 kg object is travelling left, its velocity should be substitute as -8.00 m/s.
Solving yields:
