Answer: 11.1cm
Explanation:
Object distance (u) = 32cm
Image distance(v) = 17cm
Focal length(f) =?
Lens formular:
1/f = 1/u + 1/v
1/f = 1/32 + 1/17
Taking the L. C. M of 17 and 32
1/f = (17 + 32) / 544
1/f = 49/544
Taking the reciprocal
f = 544/49
f = 11.1 cm
Therefore, Focal length of the lens is 11.1cm
The correct choice is genetic drift.
genetic drift is known as the variation in alleles number within a population and it mainly happens in small population where chances of losing an alleles are larger. it is common effect observed when significant number in a population die or when there is significant reduction in birth. hence genetic drift results in loss of genetic variation
The test charge used to determine the electric field is very, very small so that its presence does not affect the electrical field because of the supply price. The electrical rate that produces the electric area is known as a source charge.
An electric-powered area is a physical area that surrounds electrically charged debris and exerts pressure on all differently charged particles inside the area, both attracting or repelling them. It also refers back to the physical field for a machine of charged particles.
Electric-powered discipline is described as the electrical force in keeping with unit fee. The path of the sector is taken to be the route of the force it might exert on a fine check price. the electric discipline is radially outward from a nice rate and radially in toward a bad point rate.
An electric discipline is a vicinity of space around an electrically charged particle or object in which an electric charge might sense force. An electric field is a vector amount and may be visualized as arrows going in the direction of or away from fees.

Answer:
Speration between the slits
Explanation:
Given that,
Wavelength of light,
It is incident on a double slit produces a second-order maximum at an angle of 25 degree.
The condition for maxima is given as :
d = seperation between the slits
m = order, m = 2
d = 0.00000289
or
So, the seperation between the silts is
. Hence, this is the required solution.
Answer:
Both A and B are right.
Explanation:
-Electronic Stability Control (ESC) helps drivers to avoid crashes by reducing the danger of skidding, or losing control as a result of over-steering. The ESC activates in the instant that a driver loses control.
-The Sway Control is an added feature that helps eliminate trailer sway and takes action when necessary via the electric brake system, to maintain road position.
