The volume of the gasoline bottle is 15 liters. What is the weight of an entire bottle of petrol if the empty one weighs 1 kg? The density of gasoline is approximately 730 kg/m³. - Sound Doppler observer
A sound source emits a tone with an absolute pitch of 500 Hz and moves towards the observer at a speed of 5 m/s. Sound travels at a speed of 340 m/s. How fast is an observer moving who hears a tone with an absolute pitch of 522 Hz? - Kangaroo speed minutes
A kangaroo can move at a speed of 65 km/h. How many minutes will it take to move at this speed to a place 6500 m away? - Steel heat capacity
Calculate the mass heat capacity of a steel body weighing 2 kg, which was heated from an initial temperature of 15°C to 80°C by supplying 60 kJ of heat. - Coefficient of friction
A car moves along a horizontal road at a speed of 15 m/s. After turning off the engine, the car traveled a distance of 225 m. What was the coefficient of friction for this motion? - Circuit breaker power
The electric circuit breaker automatically switches off the circuit of the 220 V electrical network at a current of 6 A. Determine the maximum power in the protected circuit. - Calculate energy
A cheetah weighing 38 kg moves at a speed of 108 km/h. Calculate its kinetic energy. - 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? - The projectile
The projectile leaves the 10 m long barrel at an instantaneous speed of 500 m/s. What is the acceleration of the projectile's movement in the barrel, and at what time will the projectile pass the barrel if we assume that It evenly accelerated the motion? - Cindy run
Suppose it takes 1/3 of an hour for Cindy to run 3/5 of a mile. How many miles does she run in 1 hour? - A cold front
At 1:00 PM, the temperature was 46 degrees. Then, a cold front moved in and decreased the temperature by 12 degrees per hour. The temperature at 6:00 PM = _____ degrees. - Coulombs
How long does it take for a 15 C charge to cross the conductor's cross-section if a 3mA current passes through the conductor? - Earth and Sun
Earth is 150 million km away from the Sun. 300,000 km of sunlight travels in 1 second. How long will the light come from the Sun to the Earth? - Iron cast
What is the weight of cast iron with a volume of 3575 cubic centimeters? The density of the cast iron is 7600 kg/m3 - Passenger car
A passenger car covers 1 km in 2/3 minutes, and a truck in 50 seconds longer. How much slower is the speed of the truck? - Garden
The rectangular garden has dimensions of 27 m and 30 m. Peter and Katka split it in a ratio of 4:5. How many square meters did Katkin measure part of the garden? - Castle model
