Answer:

The correct choice is

It is thinner at the edges and thicker at the center.

Explanation:

A convex lens has to converge the rays coming towards it at a single point. For that to be possible, the lens has to be thin at the edges for the bending of light to be smaller and must be thick at the center of the bending of light to be larger there.

If a car with a mass of 1,200 kg traveling westward at 30 m/s is

forsale [732]

The net force acting on the car is equal to -12000 Newton.

<u>Given the following data:</u>

Mass = 1,200 kg

Initial velocity = 30 m/s.

Final velocity = 0 m/s (since the car came to a stop).

Time = 3 seconds.

To determine the net force acting on the car:

<h3>How to calculate the net force.</h3>

Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:

$F = \frac{m(v\;-\;u)}{t}$

<u>Where:</u>

m is the mass.

t is the time.

u is the initial velocity.

u is the final velocity.

Substituting the given parameters into the formula, we have;

$F = \frac{1200 \times (0\;-\;30)}{3}\\\\F = \frac{1200 \times (-30)}{3}\\\\F = \frac{-36000 }{3}$

Net force = -12000 Newton.

When an airplane is sitting on the ramp, which of Newton's Laws does it exhibit?

antiseptic1488 [7]

It shows the first law of Newton.

The first law states that :-

'If an object is at rest it will be at rest or if it is at motion, it will be in the state of motion until an external force is applied'

Since the airplane is at rest, it will be at rest showing the first law
