- 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? - Trisection of a line segment
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

On Sunday, the temperature was 63 degrees at 2 PM. The temperature was then 72 degrees at 5 PM. What is the rate of change per hour? - The cyclist
The cyclist reaches a speed of 32 km/h in 3.4 seconds. What is its acceleration in m/s²? - The temperature 16
The temperature at 6 AM was 21 degrees Fahrenheit. By noon, it had dropped to 32 degrees Fahrenheit. What was the temperature at noon? - Nicolas
Nicolas and his father can repair one desk in 1/3 hour. How many desks can they repair in 3 hours? - Two waves
Two waves are out of phase by 26°. If the period of the waves is 6 seconds, what is the time difference between the waves? Give your answer in seconds to 2 decimal places. - Calculate 55981
Calculate the following example: On a map with a scale of 1:50,000, two places, A and B, are 4 cm apart. Find out: a) what is the distance between these places in reality; b) what is the scale of the map in which these places are 12 cm apart? - Benhur
Benhur boiled 1 1/4 liters of water in a kettle. After 10 1/2 minutes, he measured the water again. It had 3/4 liters left in the kettle. What is the amount of water that evaporates every minute?
- The coil 2
The coil of a moving coil voltmeter is 40 mm long, 30 mm wide, and has 100 turns. The control spring exerts a torque of 240 x 10-6 N-m when the deflection is 100 divisions on a full scale if the flux density of the magnetic field in the air gap is 1.0 Wb/ - Determine 55891
