Answer:
Car speedometer only measures speed and doesn't give any information about direction. So yes to speed, no to velocity.
Answer:
Transverse wave
Explanation:
In transverse waves, particles of the medium vibrate to and from in a direction perpendicular to the direction of energy transport. 4. A transverse wave is traveling through a medium.
Answer:
Explanation:
A light year is a unit of length and is defined as "the distance a photon would travel in vacuum during a Julian year at the speed of light at an infinite distance from any gravitational field or magnetic field. "
In other words: It is the distance that the light travels in a year.
This unit is equivalent to , which mathematically is expressed as:
Doing the conversion:
This is the distance from Earth to Sirius in miles.
Answer
there are strong attractive forces between atoms of liquids with a high viscosity
Explanation:
viscosity:
Viscosity is the state of being sticky and thick . There are strong attractive forces between atoms of liquids with a high viscosity on the other hand in non viscous liquid there are weak attractive forces between atoms of liquids. A semi fluid liquid like jelly is said to be viscous. Viscosity increases with stronger inter molecular forces at normal temperature. Viscosity decreases as temperature increases
