- Outside temperature
The temperature outside was 57 degrees Fahrenheit. During the next few hours, it decreased by 18 degrees and then increased by 23 degrees. Find a new temperature. - The tourist
The tourist came started from the hostel at an average speed of 5km/h. Half an hour later, the bicyclist started along the same route at a speed of 20km/h. How many minutes will a cyclist catch up, and how many kilometers will he go? - Centimeters 6366
The weight of the pupil and the chair is 52 kg. The area of the contact surfaces of the chair with the floor is 12 square centimeters. What pressure does the chair put on the floor? - Sand
The maximum weight of the car is 5000 kg. We must transfer 10 m³ of sand. How many times does a car have to go? (density of sand is 1500 kg/m3)
- Granite cube statue
What is the weight of a granite cube with an edge length of 75 cm if one m³ of granite weighs 2.7 tons? - Equator 6020
The Equator. ..40075 km train. ..300m. How many trains would fit on the Equator? - MW oven
You plug a microwave oven into a 20 amp electrical circuit. The microwave uses as much as 12.5 amps. How many amps are available on this circuit for other appliances? - Traveling 5808
The diameter of the wheel is 56cm. How often does it turn in 5 minutes if traveling at 60km / h? - Railroad
The railroad runs parallel to the railway. The train travels at 36 km/h on track. In the opposite direction, the motorcycle rides at 90 km/h. The train passes in 3 seconds. How long is a train?
- Cross-section 5721
Calculate how much electric current flows through the circuit if a 3 C (C is SI unit - Coulombs) electric charge passes through the conductor cross-section in 30 seconds. - Electrical 5720
The bulb is connected to a 4.5 V power supply. An electric current of 45 mA flows through the filament of the bulb. The calculated size of the electrical field of the filament lamp - Electrical 5719
A resistor with an electrical resistance of 1.5 kiloohms passes through an electrical current of 0.1 amps. Calculate the electrical voltage between the resistor terminals - Coil as a girl
The electrical resistance of the copper wire coil is 2.0 ohms. What current runs through the coil when the voltage between the terminals is 3.0 V? - Thunder and lightning
There was a glimpse of the sky, and we heard thunder in 4.5 seconds. The light spreads at 300,000 kilometers per second, so we can assume the flash instantly without delay. However, the sound's speed is much lower in the air, one-third of a kilometer per
- Distance 5565
The tourist section covered 14.5 km in 2.5 hours. What distance did he cover on average per hour? - Warmer weather
This morning it was -6 °C. What temperature did the thermometer show yesterday if it was three times warmer? - Copper density
The copper roller weighs 547.4 g. determine its volume. Use copper density is ρ = 8960 kg/m³. - Material 5296
What material is the casting that weighs 45.2 g and has a volume of 4 cm³? If it is a simple chemical element, write its chemical symbol. - Inter city bus
The inter-city bus leaves Suva at 10.00 am and reaches Nadi at 1.00 pm, covering a distance of 219km. How long did it take to reach Nadi?
