A substance of mass 200g measures 50cm*4cm*8cm. Calculate it density giving your answer in SI unit​

Physics
1 answer:
Oduvanchick [21]3 years ago
5 0

Answer:

0.2kg/0.0016m^3

Explanation:

200g is 0.2 kg

50*4*8 is equivalent to 1600 cubic centimeters which is also equivalent to 0.0016 cubic meters.

The SI unit for density is kg per cubic meter

So now we have 0.2kg/0.0016m^3

I hoped this helped, and if it did please give me brainliest

balandron [24]

Answer:

correct answer is Precipitous vaginal delivery

Explanation:

given data

cervix dilated = 4 cm

effaced = 100%

delivery  = 5 minutes later

solution

correct answer is Precipitous vaginal delivery because precipitous take delivery time less than = 3 hours

A multipara progress at rate 1.5 cm of dilation per hour

and it is progress for 10 cm for the deliver and birth averages approx 20 minute

so here correct answer is Precipitous vaginal delivery

PLEASE HELP!! Newtons first law states that if an objects velocity is changing a __________ must be acting on it. Question 1 opt
Anika [276]

Newtons first law states that if an objects velocity is changing a <u>force</u> must be acting on it.

Explanation:

Newton's first law of motion states that:

"An object at rest (or in uniform motion) will remain at rest (or will continue moving with the same velocity) unless acted upon an unbalanced force"

We can apply this law to a daily life example:

  • Take a book at rest on a table: the forces acting on the book are balanced. If we do not apply any other force, we know that the book will remain at rest: this is exactly what is summarized in Newton's first law.
  • Take a space probe moving in the interstellar space, very far from any planet or source of gravitational force. Since there are no forces acting on the proble, the probe will continue moving at the same velocity (same speed and same direction) forever, unless stopped by a new force acting on it.

This means that in order to put an object at rest in motion, or to stop an object already in motion, or to change its velocity, an unbalanced force needs to be applied: otherwise, the object will continue having the same velocity (which can be either zero or non-zero), so it will continue having  same speed and same direction.

The self inductance relates the magnetic flux linkage to the current through the coil. Calculate the self inductance L in units
Katen [24]

Answer:

Self inductance, L=127\ \mu H

Explanation:

It is given that,

Length of the coil, l = 5 cm = 0.05 m

Area of cross section of the coil, A=3\ cm^2=0.0003\ m^2

Number of turns in the coil, N = 130

The self inductance relates the magnetic flux linkage to the current through the coil and it is given by :

L=\dfrac{\mu_oN^2A}{l}

L=\dfrac{4\pi \times 10^{-7}\times (130)^2\times 0.0003}{0.05}

L = 0.000127 Henry

or

L=127\ \mu H

So, the self inductance of the coil is 127 microhenry. Hence, this is the required solution.
