pentagon [3]3 years ago
3 0

Answer:

6N

Explanation:

Given parameters:

Mass of object  = 6kg

Initial velocity  = 5m/s

Final velocity  = 25m/s

Time  = 30s

Unknown:

Net force acting on the object  = ?

Solution:

From Newton's second law of motion:

   Force  = mass x acceleration

Acceleration is the rate of change of velocity with time

  Acceleration  = \frac{Final velocity  - Initial velocity }{time}  

  Force  = mass x  \frac{Final velocity  - Initial velocity }{time}  

So;

 Force  = 6 x \frac{25  - 5}{30}    = 6N

Light will not pass through a pair of polaroids when their axes are
Advocard [28]

Answer:

perpendicular

Explanation:

Polaroids are the material that is used to polarize the ray of light. Polaroid consists of microcrystals of herapathite.

When unpolarized light is passed through the Polaroid then ray appears to be of half the intensity and vibration of the ray in the single plane so, the emerged light is known as polarized light

Polaroids are used in the glasses to protect the eye from unwanted rays.

When Light does not pass through a pair of Polaroids then the axis of Polaroids will be perpendicular to the axis of ray.

Which is true regarding diffusion and osmosis? Question 3 options:
Scilla [17]

Answer:

Option (A)

Explanation:

Diffusion is defined as the transfer of particles such as ions or molecules from a higher concentration region to a lower concentration region.

Osmosis is a special type of diffusion in which the solvents such as water are allowed to move from a region of higher to a lower concentration through a layer of a semi-permeable membrane. This is an energy-independent process and occurs along the concentration gradient.

Thus, the correct answer is option (A) that is true for both osmosis and diffusion.
