State newtons second law of motion and use it to define the unit of force in cgs system.​

Answer»

Answer:

According to Newton's second law, the RATE of CHANGE of momentum is directly proportional to the applied force, so. where k is a CONSTANT. The unit of force is so chosen that k is equal to one. If m = 1, a = 1 and F = 1, then. So a unit force is that force which produces a unit acceleration in a body of unit mass.

Two stones of masses 50g and 250g are dropped from a height of 100m simultaneously. What will be the ratio of time taken by them to touch the ground? (Take g=10 m per sec square)

Answer»

Explanation:

If AIR RESISTANCE is proportional to mass of the body, then acceleration due to it will be independent of mass and hence the two bodies will reach ground simultaneously.

a=

m

mg−f

AIA

=

m

mg−mα

=g−α

This acceleration is independent of mass and hence same TIME will be required.

What maca oploia divasmic explain

Answer»

Answer:

It’s also claimed to improve energy and stamina.

What Is Maca?

The maca plant, known scientifically as Lepidium meyenii, is sometimes referred to as Peruvian ginseng.

It mainly grows in the Andes of central Peru, in harsh conditions and at very high altitudes — above 13,000 feet (4,000 meters).

Maca is a cruciferous vegetable and therefore related to broccoli, CAULIFLOWER, cabbage and kale. It has a long HISTORY of culinary and medicinal use in Peru (1Trusted Source).

The main edible part of the plant is the root, which grows underground. It EXISTS in several colors, ranging from white to black.

Maca root is generally dried and consumed in powder form, but it’s also available in capsules and as a liquid extract.

The taste of maca root powder, which some people dislike, has been described as earthy and nutty. MANY people add it to their smoothies, oatmeal and sweet treats.

It’s worth NOTING that research on maca is still in its early stages.

Many of the studies are small, done in animals and/or sponsored by companies that produce or sell maca.

What do you mean by electric field and strength?​

Answer»

Answer:

Electric field strength is a quantitative EXPRESSION of the intensity of an electric field at a particular location. The STANDARD unit is the volt per meter (V/m or v · m -1). A field strength of 1 v/m REPRESENTS a potential difference of one volt between points separated by one meter.

Unit: To convert to v/m, multiply by

V/m: 1

ΜV/m: 10 -6

NV/m: 10 -9

find the position of an object which when placed in front of a concave mirror of a focal length 20 cm produces virtual image which thrice the size of object​

Answer»

Answer :-

Position of the object is 13.33 CM from the mirror .

EXPLANATION :-

We have :-

FOCAL length = 20 cm

→ Size of image is thrice the object .

________________________________

From the question, we have :-

• hᵢ = 3hₒ

Now, from the formula of Magnification of spherical mirror :-

m = -(v/u) = h/h

⇒ -(v/u) = 3hₒ/hₒ

⇒ -(v/u) = 3

⇒ v/u = -3

⇒ v = -3u

________________________________

According to sign convention :-

• f = -20 cm

Now, let's calculate the position of the object by using the mirror formula .

1/v + 1/u = 1/f

⇒ 1/(-3u) + 1/u = 1/(-20)

⇒ -1/3u + 1/u = -1/20

⇒ (-1 + 3)/3u = -1/20

⇒ 2/3u = -1/20

⇒ 3u(-1) = 2(20)

⇒ -3u = 40

⇒ u = 40/(-3)

u = -13.33 cm

[According to sign convention, 'u' is always -ve for a CONCAVE mirror.]
