- Artificial 57081
Determine the average speed and orbit of the Earth's first artificial satellite. Its distance from the Earth's surface in the perigee was 226 km, and in the apogee, 947 km. - The space
The space rocket orbits the Earth at an altitude of 400 km above the Earth's surface. Determine the magnitude of the centrifugal acceleration of the missile in its orbit. - Tractor
A car traveling at a speed of 70km/h is overtaken by a tractor traveling at 25km/h. The driver of the car needs a toilet and knows that it will take him 3 minutes. How many kilometers does the car have to cover, so the tractor does not overtake it? - Stationary 57031
Determine the distance of a stationary satellite from the Earth's surface. - An experiment 2
The temperature of a substance in an experiment changes by -8.7°F from 10 AM to 1 PM. At 5 PM, the temperature is 33.5°F. It is 2/3 of what the temperature was at 1 PM. What was the temperature at 10 AM of the substance?
- The satellite
The satellite orbiting the Earth at an altitude of 800 km has a speed of 7.46 km/s. How long would it have to move from the start to the orbit to reach this speed if it evenly accelerated its motion in a straight line? What is the acceleration of satellit - The train
The train starts for 2 min with an acceleration of 25 cm/s². What speed will he gain in this time, and what path will he pass? - Instructions: 56651
Divide the line segment AB into three equal parts. Instructions: Construct an equilateral triangle ABC and find its center (e.g., the described circles). - Calculate 56641
The Hawaiian volcano Mauna Kea reaches a height of 4205 m above sea level. M. However, it is the highest peak on the whole Earth because its base is far below sea level. Calculate how long the volcano is hidden below sea level if the total height of the v - Acceleration 56621
The aircraft, which has a speed of 1080 km / h, starts moving for 1 minute with an acceleration of 1 m / s². What will be its final speed? What trajectory will he take at this minute?
- The Nürburgring
The Nürburgring in Germany is a racetrack that hosts racing events all year. Two of the fastest laps ever driven on the track are 6 minutes 47.30 seconds and 6 minutes 52.01 seconds. How much faster is the 6 minutes 47.30 seconds than the 6 minutes 52.01 - A rectangle 8
A rectangle measuring 6 cm and 4 cm is enlarged by the ratio of 3:1. What is the area of the enlarged rectangle? - Embankment 56451
