The bend has a radius of r = 100 m and is inclined at an angle of 20° to the horizontal plane (= tilt angle). What is the safe (the "best") speed to go through this curve? Sketch the picture regarding NIVS, mark the forces, and calculate. - Anthea
Anthea is running an experiment to examine vaccine shelf life, and she must precisely monitor the temperature. The starting temperature is −116 degrees Celsius (°C). The temperature rises by 35 degrees, then fall by 12 a degree. What is the final temperat - Two drops
Between 5:00 pm to 6:00 pm, the temperature dropped 3°C. Between 6:00 pm to 7:00 pm, the temperature dropped 4°C. What was the total drop in temperature from 5:00 pm to 7:00 pm? - North + west

The temperature at 6 P.M. is -11°Fahrenheit. During the night, the temperature rises by 7°F drops by 3°F, and rise by 5°F. What is the temperature after these changes? - Yesterday 5
Yesterday, between noon and midnight, the temperature went down by 32.1°F. If the temperature was -6.6°F at midnight, what was it at noon? - The tempture
The temperature increased 13°F between 6 AM and 3 PM. The temperature at 3 PM was 70°F. What was the temperature at 6 AM? - Temperature 68724
The thermometer showed -2 °C in the morning. By lunch, the temperature had risen by 5 °C. The temperature had dropped by 13 °C till midnight. What temperature in °C did the thermometer show at midnight? - Raindrops
The car runs on a horizontal track at a constant speed of 20 m2-1. 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 - 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? - Angle ASB
On a circle with a radius of 10 cm and with a center S, the points A, B, and C are given so that the central angle ASB is 60 degrees and the central angle ASC is 90 degrees. Find the length of the circular arc and the amount of AB and AC offsets. - Now is
Now it is 5°C in the morning. What will the temperature be if i. It rises by 12°C ii. It falls by 15°C - Mass point
Two equal forces of 30 Newtons act on a mass point. Find the magnitude of the resultant force if these forces form an angle of 42°. - Weather
Weather. At 5:00 am, the temperature was 28°C, and at noontime, it rose by 9°C. By 4:00 PM, it dropped 3°C; by nighttime, it was 4°C less. What is the room temperature this time? - At noon
At noon today, it was 6°C outside, but it has increased to 4°C since then. What is the temperature outside now? - Outdoor temperature
The outdoor temperature was 8 degrees at midnight. The temperature declined 5 degrees during each of the next 3 hours. What was the temperature at 3 AM? - Overtaking
On the direct road, the passenger car overtakes the slower bus by starting to overtake 20 meters from the bus and after passing it ahead of it again 20 meters away. The car overtakes at a steady speed of 72 km/h. The bus goes at a steady speed of 54 km/h.
