A chameleon is resting quietly on a lanai screen, waiting for an insect to come by. Assume the origin of a Cartesian coordinate system at the lower left-hand corner of the screen and the horizontal direction to the right as the +x -direction. If its coordinates are (2.000 m, 1.000 m), (a) how far is it from the corner of the screen? (b) What is its location in polar coordinates?
Hi, Could you please check your answer for part a? The answer cannot be 6.648E-26 N. Thanks!
a snake crawls from a hole to find food. it starts at 8m southwest; then goes 10m 40 degrees north of west; then sensed something moving 9m south from where it is and moves to it. a. how far and in what direction was the moving object from the hole? b. if after realizing that the moving object was not good for food, the snake moved from it because it saw another moving thing, moved to its direction by covering a fourth displacement and is now 20m and 30 degrees east of south from the hole. what is the magnitude and direction of the fourth displacement?
Please solve this problem and show the solution. Thank youP.S my answer was 1.6*10^5, I might be wrong. I just want to clarify my answer
Hello, can you please help me with this. Based on the first page can you please help me fill out table 2 completely ñ. Thanks (:
You need to guide a robot from the red dot on the left to the green dot on the right, avoiding the blue walls along the way. units To do this, you must feed it a series of commands of the form "turn degrees and move forward". Angles are measured in degrees, with positive angles turning counterclockwise, and negative angles turning clockwise. All turns are relative to the robot's current direction. The grid marks 1 unit squares. From the red starting dot, with the robot facing directly to the right, issue your commands: (all commands should be given as decimal values) Move 1: Turn 9 Move 2: Turn Move 3: Turn Move 4: Turn degrees and move degrees and move degrees and move degrees and move units forward units forward units forward units forward

The Earth is 8 light minutes from the sun and the speed of light is 3 x 10° m.s. Let's assume that earth's orbit is exactly circular. Its mass is 5.972 × 1024 kg. Using the values given above (and your knowledge about time units), determine the magnitude of the gravitational force that the Sun exerts on the Earth. The magnitude of the force is newtons. Format: if your answer is 2 × 10° N, enter 2*10^3 (and do think about significant figures)

Illuminance is a measurement of how much light is incident on a surface. It varies with the square of the distance of the object from the light source. Illuminance (lx)- amount of light falling on 1 m^2 area Please answer numbers 1 and 2 1. Compute for the illuminance in your room. 2. Search for the ideal illuminance in the areas of the house (living area) and give area in your house that needs more light. Kindly give explanation how'd you come up with your answer.

The expression above was obtained from the interaction of a massless Higg s Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = Fx dx Evaluating the above, we get W = aln | x beta e X 3/5 5 for the limits from x¡ to xf substituting x1 and x2 as the limits, the work done is expressed as W = | + X1 e ( x15 x2 ) x2 MacBook Pro
