  • 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, 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 circle arc and the amount of AB and AC offsets.
  • Now is
    Now is 5°C 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, and 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 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 3am?
  • 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.
  • Paratrooper
    After the parachute is opened, the paratrooper drops to the ground at a constant speed of 2 m/s, with the sidewinding at a steady speed of 1.5 m/s. Find: a) the magnitude of its resulting velocity concerning the ground, b) the distance of his land from a
  • Outside temperature
    The temperature outside was 57 degree Fahrenheit. During the next few hours it decreased by 18 degrees and then increased by 23 degrees. Find new temperature.
  • Air pressure
    The meteorological station measured the air pressure of 1060 hPa (hectopascals). In addition to measuring instruments, there is a residential house that has a flat roof with dimensions of 10 m and 28 m. What pressure force in MN (meganewtons) force the ai
  • Two forces
    Two forces with magnitudes of 25 and 30 pounds act on an object at 10° and 100° angles. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and your final answer.
