- Water mixing
We mix 2 liters of water at 100 degrees Celsius warm and 18 liters of water at 32 degrees Celsius warm. What temperature will the water have after mixing? - Temperature 16633
What heat do we need to supply a copper body weighing 8 kg to raise its temperature by 136 degrees Celsius? - Calculate 16623
Calculate the density of 2.5 tons of wood, knowing it takes up three cubic meters. Express the result in g / dm cubic. - Seconds 15853
The body landed on Earth in 9 seconds. Find from what height it fell and what its speed was on impact.
- Equilibrium 15833
Two boys of masses 40 kg and 50 kg want to make a swing out of a log 3.6 m long. How far from either end must he support it, so they are in equilibrium? How can this be calculated with a single equation? And calculate the rest. - Water current
John swims upstream. After a while, he passes the bottle, and from that moment, he floats for 20 minutes in the same direction. He then turns around and swims back, and from the first meeting with the bottle, he sails 2 kilometers before he reaches the bo - Skid friction
Find the smallest coefficient of skid friction between the car tires and the road so that the car can drive at a 200 m radius at 108 km/h and does not skid. - The bridge
A vehicle weighing 5,800 kg passes 41 km/h on an arched bridge with a radius of curvature of 62 m. What force pushes the car onto the bridge as it passes through the center? What maximum speed can it cross over the bridge's center so it does not fly off t - Same force
The trunk is 5m long and 95 kilograms and has a center of gravity of 2m from the thicker end. The tribe is carried by two men, one at the thicker end. At what distance does the trunk carry a man from the other end to make the same force on it?
- Angled cyclist turn
The cyclist passes through a curve with a radius of 20 m at 25 km/h. How much angle does it have to bend from the vertical inward to the turn? - Rotaty motion
What minimum speed and frequency do we need to rotate with the water can in a vertical plane along a circle with a radius of 70 cm to prevent water from spilling? - Newtonmeters
The driver loosened the nut on the car wheel with a wrench that held 20 cm from the axis of the bolt. He acted on the key with a force of 320N. At what moment did he act on the bolt? - Motion
The two bodies move in the same direction evenly in a straight line, at speeds of 5 cm/s and 10 cm/s. The movement of the first body started 2 seconds earlier than the movement of the second body, from a point located at a distance of 20 cm from the start - Atmosphere 14493
What allows a person to walk the Earth: a) atmosphere b) Earth response c) feet d) rolling friction
- Escaping 14483
The rocket develops a higher speed, which is: a) higher velocity of escaping gases b) higher mass of escaping gases c) greater momentum of escaping gases d) shorter rocket length - 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. - Cyclists 13831
Two cyclists left one place on the circuit facing each other. The first drove at a speed of 32 km/h, and the second at 28 km/h. How long was the circuit if the cyclists met in 5 minutes? - Wheelchair
The boy pushes the wheelchair with a force of F1 = 20N. The wheelchair exerts a force of F2 on the boy. How large is this force? - Cheetah vs antelope
When the cheetah began chasing the antelope, the distance between them was 120 meters. Although the antelope ran at 72km/h, the cheetah caught up with it in 12 seconds. What speed was the cheetah running?
During the experiment, water flows evenly into a cylinder-shaped container. At the end of the 5th minute of the experiment, the water level was 25% higher than at the beginning of the experiment. 0 how many percent higher will the water level be at the enDo you have homework that you need help solving?
