A. The SI units of velocity are m/s.
B. For velocity, you must have a number, a unit, and a direction.
C. To calculate velocity, divide the change in the distance by time.
D. The symbol for velocity is .
Answer
A. The SI units of velocity are m/s.
B. For velocity, you must have a number, a unit, and a direction.
Explanation
Velocity is the rate of change of displacement. Velocity unlike speed it is a vector quantity. This means that it has both direction and magnitude. The SI unit of displacement is metres while that of time is seconds. So, the SI units of velocity will be Metres per second. From the choices in the question the statements that are true about velocity are ;
A. The SI units of velocity are m/s.
B. For velocity, you must have a number, a unit, and a direction.
Answer:
A. The SI units of velocity are m/s.
B. For velocity, you must have a number, a unit, and a direction.
C. To calculate velocity, divide the change in the distance by time.
Explanation:
A - SI units for velocity are meters per second. SI (International System) of units is the metric equivalent for units, and m/s are the standard units chosen for velocity under the SI standards.
B - Velocity is a vector, meaning it has magnitude and direction. Because velocity is essentially a speed with direction, it must have units for how fast an object is moving.
C - One method of calculating velocity is distance over time: v = Δ(d/t)
D. Not sure because I'm not seeing a variable here, but the variable for velocity is generally displayed by the letter v
Answer:
A precipitation reaction is a reaction between two aqueous Solutions that results in the formation of a solid compound.
Explanation:
lithosphere
outer core
upper mantle
In the video this question was provided for, you should be able to find the passage, "The lithosphere is a rigid shell made up of plates. In order to understand what the plates are like, imagine taking a hard-boiled egg and cracking it all over. Do not peel it; just crack it. It is still all together on the outside of the egg, but it is broken into "plates." The plates of the lithosphere move slowly about on the plastic, formless asthenosphere beneath."
Answer: Lithosphere
Its "biosphere and atmosphere" because photosynthesis comes from the plants and the atmosphere then consumes the carbon.
Kinetic energy transforms into potential energy.
B.
Mechanical energy transforms into sound energy.
C.
Elastic energy transforms into kinetic energy.
D.
Potential energy transforms into elastic energy.
Answer:
a lithosphere
a biosphere
a cryosphere
the answer is bioshere
Answer:
A biosphere
Explanation:
Biosphere refers to the zone of life on a planet. It includes all living elements of a planet. It is also known as Eco-sphere and includes the interaction of all living being with their surrounding.
Of all the planets and exo-planets, Earth is the planet known to have life and thus biosphere.
Whereas atmosphere, lithosphere and cryosphere can be found on other planets as well.
Atmosphere: Layer of air and gases surrounding a planet or any celestial object. (Except Mercury, all the planets of solar system have atmosphere)
Lithosphere: it refers to the rigid outer part of the planet which includes crust and mantle. (All the rocky planets have lithosphere)
Cryosphere: portion of the planets where water is in ice form. (Many exoplanets have been discovered having cryosphere)
