In Illinois the engine noise emitted by motorized vessels must not exceed what level when measured from a distance of 75 feet?
In Illinois, the engine noise emitted by motorized vessels must not exceed 90 decibels when measured from a distance of 75 feet. This regulation is in place to minimize noise pollution and ensure a more pleasant experience for all users of waterways. It is important for boaters to be aware of and comply with these noise level restrictions.
What else can I help you with?
What is the rate at which light is emitted from a source?
The rate at which light is emitted from a source is typically measured in watts, which represents the amount of energy being emitted per unit time. This can vary based on the type of source and its efficiency in converting electrical energy into light.
What is measured in the unit candelas?
candela measures the amount of light emitted in the range of a (three- dimensional) angular span.
How is temperature of an object measured?
Temperature of an object can be measured using tools such as thermometers, infrared thermometers, or thermocouples. These devices detect thermal energy emitted by the object and convert it into a temperature reading.
Carbon footprint is measured in units of what gas?
The carbon footprint is measured in the amount of carbon dioxide (CO2) that has been emitted over the full life cycle of a product or service.
The power pf light bulbs in Measured in?
The power of light bulbs is measured in watts (W), which indicates the amount of energy consumed and the brightness of the light produced. The higher the wattage, the brighter the light emitted by the bulb.
What is a measure of the intensity of heat emitted by an object or substance?
Temperature is a measure of the intensity of heat emitted by an object or substance. It indicates how hot or cold an object is relative to a reference point. Temperature is typically measured in degrees Celsius or Fahrenheit.
What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
The detection of physical energy emitted or reflected by physical objects is called?
The detection of physical energy emitted or reflected by physical objects is called remote sensing. This technology is used to gather information from a distance by recording and analyzing the energy that is emitted or reflected by objects on the Earth's surface.
How is brightness measured in the context of light sources?
Brightness of light sources is measured using a unit called lumens. Lumens indicate the total amount of visible light emitted by a source, with higher lumens corresponding to greater brightness.
Is there a method of measuring radioactivity from a satellite or from a remote distance?
i don't know but for sure their must be some method to measure the radioactivity from distance. and fist of all radioactivity is phenomenon in which radioactive elements emit some rays so the intensity of those rays can be measured from the distance
Radiation measured in emissions is called what?
Radiation measured in emissions is referred to as radioactivity, specifically in terms of the amount of ionizing radiation emitted by a radioactive source. This is usually measured in units such as becquerels (Bq) or curies (Ci), which indicate the rate of radioactive decay.
Why can astronomers use the speed of light to calculate distances?
Because visible light is emitted at a known frequency (a time) and then it is as simple as Speed = Distance / Time therefore Distance = Speed x Time.
