Difference between si unit and derived unit​

Physics
1 answer:
Alja [10]3 years ago
6 0

Answer:

Derived units are derived from these 7 base units. Derived units are dependent on the base units and are not independent of each other. ... Mass has SI units of kg, distance is measured in m and t has the SI unit of second. Thus, SI unit of force is kg.

The cell belongs to the then musculoskeletal system of the body.

<h3>What type of cells contains filaments that can cause the cell to contract, shortening the length of the cell?</h3>

The myocytes or muscle cells are special cells found in smooth, cardiac, and skeletal muscles that have differentiated for the specialized function of contraction.

Myocytes are long, cylindrical, multi-nucleated, and striated. They contain filaments that can cause the cell to contract, shortening the length of the cell.

Skeletal muscle cells contain many mitochondria required to generate sufficient ATP since skeletal muscle cells have high energy requirements.

The muscle cells form a part of the musculoskeletal system of the body.

In conclusion, muscle cells are required for muscular contraction.

A rock is dropped into the Grand Canyon. It takes 18 seconds to hit the bottom. Calculate how deep the canyon is.
bonufazy [111]
The distance it falls is given by
x = (1/2)at^2
where a = acceleration due to gravity = 9.8 m/s^2
x = (1/2)(9.8)(18)^2
x = 1587.6 m
The answer is 1587.6 meters

A 30-kg child sits at the top of a 3-meter slide. After sliding down, the child is traveling 4 m/s. How much PE does he start wi
Jobisdone [24]
At the top:

         Potential Energy = (mass) x (gravity) x (height)

                                       = (30 kg) x (9.8 m/s²) x (3 meters)

                                       =      882 joules

At the bottom:

           Kinetic Energy  =  (1/2) x (mass) x (speed)²

                                       = (1/2) x (30 kg) x (3 m/s)²

                                       =        (15 kg)  x  (9 m²/s²)

                                       =              135 joules .

He had  882 joules of potential energy at the top,
but only  135 joules of kinetic energy at the bottom.

Friction stole  (882 - 135) = 747 joules of his energy while he slid down.
The seat of his jeans must be pretty warm.

When a burning stick of increase is moved fast in a circle a circle of red light is seen.​
anzhelika [568]

Answer:

The impression of the image on the retina lasts for about 1/16th of a second after the removal of the object. If a burning stick of incense is revolved at a rate of more than sixteen revolutions per second, we see a circle of red light due to persistence of vision.
