Weegy: Velocity is considered to be a vector. User: Which system of measurement has been standardized worldwide for scientific uses? A. The French System B. The Systeme International C. The English System D. The Arabic System Weegy: The Systeme International is the system of measurement that has been standardized worldwide for scientific uses. User: A body is a particular amount of matter. It can be a solid, liquid or gas. It can be described as existing in A. motion and force. B. location and movement. C. size and shape. D. time and space. Weegy: A body is a particular amount of matter. It can be a solid, liquid or gas. It can be described as existing in time and space. (More)

Weegy: The velocity of a skateboarder whose momentum is a 100 kg is 6.67 m/s. Solution: p=mv; 100Kg m/s =15Kg x v; v=6.67 m/s. (More)

Weegy: Any object that has motion has kinetic energy, [ while any object not in motion but with the potential to do work has potential energy: -most accurately differentiates potential and kinetic energy. ] User: If the gauge pressure of a gas is 114 kPa, what is the absolute pressure? Weegy: If a gauge pressure of a gas is 114 kPa, the absolute pressure is 214kPa. User: What's the temperature 32 degrees Fahrenheit in degrees Celsius? Weegy: 32 degrees Fahrenheit is 0 degrees in Celsius. User: If a gas has a gauge pressure of 156 kPa, its absolute pressure is approximately Weegy: absolute pressure = 156 + 100 kPa = 256 kPa Thus, its absolute pressure is approximately 256 kPa. User: A 63 kg object needs to be lifted 7 meters in 5 seconds. Approximately how much horsepower is required to achieve this task? Weegy: A 63 kg object needs to be lifted 7 meters in a matter of 5 seconds. Approximately 1.16 hp is required to achieve this task. [ power = work done /time taken = mgh/time = 63*9.8*7/5 = 4321.8/ 5 = 864.36 , 1 HP = 746 watts , horsepower = 864.36/746 =1.16hp ] User: The waste products of combustion leave the internal-combustion engine through the Weegy: The waste products of combustion leave the internal combustion engine through the exhaust valve. User: If the absolute temperature of a gas is 600 K, the temperature in degrees Celsius is Weegy: If the absolute temperature of a gas is 600 K, the temperature in degrees Celsius is 327 C. User: Convert the temperature 288 K to degrees Celsius. Weegy: 288 kelvin = 14.85 degrees Celsius. User: Convert the temperature 288 K to degrees Celsius. 0 A. 748°C • B. - 172°C • C. 561°C • D. 15°C Weegy: The temperature 288 K to degrees Celsius is 15 C. User: If a total force exerted by water in a container with a bottom area of 2 square meters is 450 newtons, what's the water pressure at the bottom of the container? Weegy: If a total force exerted by water in a container with ... (More)

Weegy: Your brother is insisting that you'll never hear a sound produced behind a barrier wall at the end of your yard. You notice that the door within the wall is open and quickly explain to him that the sound will be able to reach you due to: diffraction. User: The function of the eardrum is to • A. vibrate with the frequency of the received sound. • B. collect the sound waves. • C. carry the sound energy to the brain. • D. amplify the received sound. Weegy: The function of the eardrum in the middle ear is to vibrate with the frequency of the received sound. User: If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave? Weegy: If a wave has a wavelength of 9 meters and a period of 0.006, the velocity of the wave is 1500 m/s. Solution: 9 / 0.006 = 1500. User: A wave with a period of second has a frequency of • A. 300 Hz. • B. 3 Hz. C. 33 Hz. D. 67 Hz. Weegy: A wave with a period of 1/3 second has a frequency of 3 Hz. f = 1/T = 1/(1/3) = 3 User: What part of the human ear contains the eardrum? Weegy: The "middle ear" contains the eardrum. User: The longest wavelength within the visible spectrum is - • A. orange O B. blue O C. red • D. violet _ light. Weegy: 2x-8User: The longest wavelength within the visible spectrum is - Weegy: 2x-8User: Which of the following statements is true of vibrations? (More)
