What else can I help you with?
Wind speed is often measured with an anemometer true or false?
true
Newton's work showed that speed of light and sound were constant true or false?
False. Newton's work did not involve the speed of light and sound. The concept of constant speed of light was later formulated by Einstein in his theory of relativity. The speed of sound can vary depending on the medium it travels through.
The speed of sound traveling thruogh steel is much more than the speed traveling through air?
False
Is this true or false the length of a planet's year is determined by how fast it spins?
False, the speed it spins on it's axis determinds the length of day. The speed it rotates the sun determinds the length of it's year.
When the temperature of a medium increases the speed of sound decreases true or false?
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.
Wind speed is often measured with an anemometer true or false?
true
True or False - The speed of light is directly proportional to the distance traveled please explain why?
False. The speed of light is always the same: 300,000 kilometers per second.
Is the following true or false in space light travels at the speed of 3000000 kilometers per year?
False. In space, light travels at a speed of approximately 299,792 kilometers per second, not per year. This means light can travel about 9.46 trillion kilometers in one year, known as a light-year.
True or false- The volume of a gas cannot be measured?
false
Is the wave length measured from the crest to the trough true or false?
False. The wavelength of a wave is actually measured from crest to crest, or trough to trough, not from crest to trough.
Heat is measured in Celsius degrees true or false?
False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.
Is wave length is measured from crest to the trough?
False, it is measured from crest to crest.
The volume of a gas cannot be measured?
FALSE
Is a toothpick measured in milligrams?
no
Is it true or false that motion is measured in relationship to a point of reference?
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
The number of males in the US is measured in the thousands?
false
The number of days in a week is measured in the ones?
false
