The moon is 1.3 light-seconds away. Imagine you are standing at the Canadian Space Agency headquarters in St. Hubert, Quebec and you bounce a 755 MHz radio signal off the moon (the moon acts like a mirror, reflecting the signal, such that it comes back to you). How long will it take for that radio signal to get back to you on earth? Answer in seconds with one decimal place.
A small light source located 1 mm in front of a 1-m2m2 opening illuminates a wall behind. If the wall is 1 mm behind the opening (2 mm from the light source), the illuminated area covers 4 m2m2. How many square meters are illuminated if the wall is 3 mm from the light source? 5 mm? 10 mm?
Using a single dimensional equation, estimate the number of steps it would take a person with a step length of 2.65 ft to walk from the Earth to Alpha Centauri a distance of 4.37 light-years. The speed of light is 1.86282 x 105 miles/s. Number of Steps = Enter your answer in accordance to the question statement x 1017

- I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.arrow_forwardA light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 x 10^8m/s) 5 light-minutes 6 light-days 6 light-days, but this time answer in miles (enter just the number with no units)arrow_forwardThe speed of light is about 3 x 108 meters per second. The Millennium Falcon is traveling from Earth to Mars at the speed of light. The distance between the Earth and Mars fluctuates between 5.46 x 10¹0 meters and 4,01 x 10¹¹ meters. If the day the Millennium Falcon makes the "Mars Run," the distance is 2.25 x 10¹¹ meters, how long will it take them? Note: distance = rate time, and time = distance/rate Express your answer in scientific notation. Use for the multiplication. seconds Convert your answer to minutes. Include at least 3 decimal places in your answer, which can be expressed in standard notation. minutes Suppose the Millennium Falcon flies for 5 hours at the speed of light. How far will they travel? Express your answer in scientific notation. metersarrow_forward
- What is the number of miles in a light-year, using (see picture) mi/s as the speed of light? I know the number of seconds in a year and 365 days will help but confused on how to put it in the equation.arrow_forwardCalculate the angle a person needs to lean from the vertical when 1. walking a 14 m (radius) circular track at 22 mins per mile, and Enter to 2 significant figures Angle with respect to the vertical = = 0.85 ! No, that's not the correct answer. O 2. running at 4 min per mile. Enter to 2 significant figures Angle with respect to the vertical = 6.8 Use 1 mile = 1609.4 m Sense-making: Do your results for the leaning angle during walking agree with your observations about people walking on circular tracks? Oarrow_forwardThe Planck time is the unique interval of time that can be built out of G, c, and h. Some physicists think that time intervals shorter than the Planck time have no meaning. Using G = 6.7 x 10-11 kg-1 m3 s-2, c = 3 x 108 m s-1, and h = 6.6 x 10-34 kg m2 s-1, calculate the Planck time, in units of 10-43 s.arrow_forward
- (the complete question is in the picture) If the Newtonian constant has units G = [N · m2/kg2], the speed of light has units c = [m/s], the mass has units M = [kg] and the SI unit newtons is equivalentto N = [kg · m/s2], what are the units of the relation GM/c3?A. [kg · s]B. [kg · m2/s]C. [m2/s]D. [s]arrow_forwardThe speed of light is 2.998*10^8 m/s. How far does light travel in 7.0 μs ? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.arrow_forwardIn the Snellen visual acuity chart, the letters in the 20/40 line subtend an angle of 3 milliradians with respect to the eye when viewed at a distance of 6 meters ( i.e., approximately 20 feet ). Using the small-angle approximation, calculate the actual height of the 20/40 letter, in units of mm?arrow_forward
- A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s). 1. 4 light-seconds 2. 3 light-minutes 3. 2 light-days 4. 2 light-days, but this time answer in miles (enter just the number with no units)arrow_forwardI don't understand how to really calculate these answers with the given info. how do I solve this?arrow_forwardAt the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner radius is 10 yd and its outer radius is 14 yd. 10 yd 14 yd We are going to give a new layer of coating to the path. If one gallon of coating can cover 6 yd, how many gallons of coating do we need? Note that coating comes only by the gallon, so the number of gallons must be a whole number. (Use the value 3.14 for a.) I gallons of coatingarrow_forward
