What is the longitude and latitude of Jaipur?
26.9124° N, 75.7873° E
What are the main properties of parallels and meridians?
A. ANSWER THESE QUESTIONS.
| Parallels | Meridians |
|---|---|
| Parallels don’t intersect. | All meridians intersect at two places, the North Pole and the South Pole. |
| The first parallel is the equator. It is latitude 0. | Greenwich is the prime meridian (0°) |
| Every parallel is a full circle. | Every meridian is a semi-circle |
What do meridians calculate?
Each meridian measures one arcdegree of longitude. The distance around the Earth measures 360 degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees.
What is the formula to find time?
time = distance ÷ speed.
What is the equation of time today?
The precise definition of the Equation of Time is E = GHA (apparent Sun) – GHA (mean Sun) (1) where GHA is the Greenwich hour angle. An alternative formula often quoted in text books is E = right ascension of the fictitious mean Sun – right ascension of the apparent (actual) Sun.
What causes equation of time?
Its value is 0, 1, or 2 at different times of the year. Subtracting it leaves a small positive or negative fractional number of half turns, which is multiplied by 720, the number of minutes (12 hours) that the Earth takes to rotate one half turn relative to the Sun, to get the equation of time.
Is time based on the sun?
Solar time is a calculation of the passage of time based on the position of the Sun in the sky. The fundamental unit of solar time is the day, based on the synodic rotation period. Two types of solar times are apparent solar time (sundial time) and mean solar time (clock time).
How do you solve time without distance?
Aside: in general, you can calculate time without knowing the distance (ie distance travelled) if you have enough other information. d = (v-u)T/2 and v = u+ aT (all the other equations can be derived from these two).
How do you solve time and distance problems?
The formula for distance problems is: distance = rate × time or d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
What is the free fall formula?
Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as gravity x time.
