Could you give me 4 examples of acceleration??
Answers
1). A driver presses the gas and the car speeds up.
2). A driver presses the brake and the car slows down.
3). A driver turns the steering wheel slightly. The car's speed doesn't change
as it goes around the curve.
4). A stone is tossed into the air. Gravity accelerates it from the moment it
leaves the thrower's hand until it hits the ground.
5). A new TV satellite is successfully launched and placed in a perfect circular
orbit around the Earth. The satellite's motion is accelerated forever, 24/7/365 .
"Acceleration" means any change in the speed or direction of motion. Any
object that's not moving at constant speed in a straight line is accelerated.

Answer:
To make a coffee cup appear larger than a basketball in a photograph, you can use the concept of forced perspective. Forced perspective is a photography technique that manipulates the perception of relative size and distance between objects in the frame. Here's how you can achieve this effect:
Place the Objects: Position the coffee cup and the basketball in the frame so that they are not directly next to each other but at different distances from the camera. The coffee cup should be closer to the camera, and the basketball should be farther away.
Adjust the Camera Angle: Align the camera at an angle that makes the coffee cup look much larger than the basketball. You'll need to experiment with the camera angle to get the desired effect.
Use a Narrow Depth of Field: Employ a camera with a controllable aperture (e.g., a DSLR or a camera with manual settings) and set it to a wide aperture (small f-number). This will create a shallow depth of field, making the objects that are not in the same plane appear more out of focus. The coffee cup, which is closer to the camera, will appear in focus, while the basketball in the background will appear blurred.
Frame the Shot Carefully: Compose the shot in such a way that the coffee cup appears prominently in the foreground, and the basketball is in the background but still visible. Make sure the viewer can distinguish the relative sizes of the two objects.
Experiment and Refine: Take multiple shots and review them on your camera's display to fine-tune the forced perspective. Adjust the camera angle, aperture, and framing as needed to achieve the desired effect.
By carefully manipulating the camera angle, depth of field, and composition, you can create the illusion that the coffee cup is much larger than the basketball, even though they are of different sizes in reality. This technique relies on the viewer's perception of the relative positions and sizes of objects within the frame.

Explanation:
Speed of light is always constant irrespective of the wave source's motion and the observer's inertial frame of reference. So, no matter how fast the car is moving the speed of light will always be constant. The speed of light in air is around 299704644.54 m/s. The meter is also defined by the speed of light as 1 meter is the distance travelled by light in 1/299792458 second.

the jeep:
Answers
- Initial velocity,u = 0 m/s
- Final velocity,v = 60 m/s
- Time taken,t = 5 min = 5 × 60 sec = 300 seconds
Calculate the acceleration ( a ) and distance (s ) covered by the jeep.
We will first calculate the acceleration of the jeep.
CASE 1 :
By Using first equation of motion ,
Thus,the acceleration of the jeep is 50 m/s².
Now, Let us calculate the distance travelled by the jeep.
CASE 2 :
By Using third equation of motion ,
Thus,the distance covered by the jeep is 36 m .
