At what acceleration moves a train with a weight of 800 t start if the traction force of the locomotive is 2 * 10 ^ 5 N? - Raindrops

The car runs on a horizontal track at a constant speed of 20 m^{2}-1. It is raining. Raindrops fall in a vertical direction at a speed of 6 m/s. a) How fast is the speed of the drops relative to the car windows? b) What is the angle of the raindro - Science experiment

During a Science experiment, a liquid was heated at the rate of 8 degrees Celsius per minute for 10 minutes. It was then allowed to lose heat at the rate of 6 degrees Celsius per minute. If the final temperature was 76 degrees Celsius, what was its temper - Faucets

A large tank is partially filled with a solution. The tank has a faucet that allows solution to enter the tank at a rate of 16 3/4 liters per minute. The tank also has a drain that allows solution to leave the tank at a rate of 19 4/5 liters per minute. ( - Brian 2

Brian and Jake left their homes, which are 500 miles apart, and drove straight toward each other. It took 4 hours for the two to meet if Jake's speed was 15 mph slower than Brian's speed. What was Brian's speed? - Kamal

Kamal walks to his school which is at a distance of 3 km from his home in 30 minutes. On reaching he finds that the school is closed and comes back by a bicycle with his friend and reaches home in 20 minutes. His average speed in km/h is - The tourist

The tourist will cross a 5 km long section in 3 hours. Part of the journey goes at a speed of 0.8 m/s and the other part at a speed of 0.4 m/s. Find the length of the first and second part of the journey. - Two forces 3

Two forces of magnitude 8 Newtons and 15 Newtons respectively act at a point. If the resultant force is 17 Newtons, find the angle between the forces. - Cooker spiral

A current of 4.4 A flow through the spiral of the electric cooker at a voltage of 220 V. What is the resistance of the spiral? - At what

At what speed did the motorist drive when he reacted by noticing the obstacle by 0.8 s; the magnitude of the opposite acceleration during braking was 6.5 m/s ^ 2 and the car ran to a stop track 35 m? - Manganin

How long must a manganin wire with a diameter of 0.8 mm have to have a value of 10Ω? - The temperature 17

The temperature was -5 Celsius at 6 AM. It increased force of three degree 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 space

The space rocket orbits the Earth at an altitude of 400 km above the Earth's surface. Determine the magnitude of the centrifugal acceleration of the rocket in its orbit. - An experiment 2

The temperature of a substance in an experiment changes by -8.7°F from 10 AM to 1 PM At 5 PM, the temperature is 33.5°F. It is 2/3 of what the temperature was at 1 PM. What was the temperature at 10 AM of the substance? - The satellite

The satellite orbiting the Earth at an altitude of 800 km has a speed of 7.46 km/s. For 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 sate - 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 Nürburgring

The Nürburgring in Germany is a racetrack that hosts racing events all year. Two of the fastest laps ever driven on the track are 6 minutes 47.30 seconds and 6 minutes 52.01 seconds. How much faster is the 6 minutes 47.30 seconds time than the 6 minutes 5 - Change per hour

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, and the temperature dropped 32 degrees Fahrenheit. What was the temperature at noon?
