- Car acceleration time
The car starts with constant acceleration, and at a distance of 567 m, it has a speed of 12.6 m/s. How long will it take from the start? - Locomotive pressure
What is the pressure on the tracks when a 10-ton locomotive with eight wheels stands on it, and each wheel has a contact area of 4 cm²? - Light year
A light-year is a unit of length that expresses the distance light travels in one year. What distance will it travel if the speed of light is approximately 300,000 km/s? - The salary 2
The salary for a group of executives was listed as follows: 18 at P50,000:10 at P60,000; 8 at P75,000:2 at P90,000; and two at P10,000. The average salary is: - Class height average
In the 8 A class, the average height of 12 girls is 156 cm, and the average height of 14 boys is 172 cm. Calculate the average number of students in 8 A. - Specific heat
How much heat must be added to convert 25 kg of ice at −15 °C into water at 23 °C? The specific heat of fusion of ice is 333 kJ/kg. - Height from Impact Velocity
From what height did a body weighing 9.8 kg fall if it hit the surface at a speed of 100 km/h? - Vehicle distance time
The speed of the moving vehicle is 40 km/h, and it must cover a distance of 1080 meters. How many minutes will it take? - Mercury density measurement
10 ml of mercury has been measured to weigh 0.135 kg. Calculate the density of mercury and compare it with the density shown in the tables. - KiloJoules energy
In the washing machine, 6 liters of water were heated from a temperature of 22 degrees to 62 degrees. Find out the weight of 6 liters of water. What heat (in kJ= kiloJoules) did the water receive? - Aluminum resistance temperature
An aluminum wire has a resistance of 4.25 ohms at 0 degrees. Determine its resistance at a temperature of 200 degrees Celsius. The temperature coefficient of the electrical resistance of aluminum is 4.4·10-3 1/K. - Truck rail pressure
How much pressure on the rails will cause an empty truck weighing 20 tons if the contact area of all wheels and rails is 16 square centimeters? - Acceleration and force
On a sphere weighing 100 g, which lies on a horizontal plate, a force acts in the horizontal direction, which gives it an acceleration of 20 cm/s². Find the magnitude of the force. - The temperature 17
The temperature was -5 Celsius at 6 AM. It increased by a speed of three degrees every hour for six hours. The temperature then increased 1 1/2° every hour for five hours. What was the temperature at 5 PM? - The cyclist
The cyclist reaches a speed of 32 km/h in 3.4 seconds. What is its acceleration in m/s²? - A plane
A plane is flying at the rate of 350 mph. After an eight-hour flight is at its destination, how far did the plane fly? - Cage gravitational energy
Find the potential gravitational energy of a 2000 kg tow cage relative to the bottom of an 850 m deep draw pit when the cage is on the surface. - Compressed gas
The pressure vessel contains a compressed gas at a temperature t1 = 27 °C and a pressure p1 = 4 MPa. How much does its pressure change when we release half the amount of gas, and its temperature drops to t2 = 15 °C? - Hydraulic blade force
The hydraulic blade has pistons with an area of 10 cm² and 500 cm². How much force acts on the larger piston if we act on the smaller piston with a force of 100 N? - Current in the conductor
Calculate the current in the conductor (in mA) if it is connected to a 4.5 V voltage source and its resistance is 20 (ohm).
