1. during a collision, the person not wearing a seatbelt is already in motion. there is no outside force (the seatbelt) to stop this motion.
2. Kinetic Energy = 0.5 * m * v^2 because velocity is a squared term, doubling the velocity actually quadruples the kinetic energy, making the stopping distance much much greater
3. by the same logic as above, mass is not a squared term, therefore doubling the mass will double the kinetic energy, increasing the stopping distance -- but by not as much as increasing the velocity.
4. because a driver cannot alter the mass of his vehicle, the best way to enter sharp curves would be decreasing velocity (speed)
5. there are many factors that determine the degree of damage (to humans and property in a crash), most notably the size of the vehicle(s) and velocity.
Figure 1: An image — an array or a matrix of pixels arranged in columns and rows.
In a (8-bit) greyscale image each picture element has an assigned intensity that
ranges from 0 to 255. A grey scale image is what people normally call a black and
white image, but the name emphasizes that such an image will also include many
shades of grey.
Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel
values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales.
A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour”
image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16
million colours.

Answer:
The correct answer to the following question will be 2. the operator new.
Explanation:
New operator is used to allocating the memory to the instance object.The new object can be created by using a "new" keyword in java .
Syntax of using 'new' operator is :
class_name object_name=new class_name() // it allocated the memory to the class
For Example :
ABC obj = new ABC;
Now, this time obj points to the object of the ABC class.
obj = new ABC ();
call the construction of ABC class
