What are the challenges faced by electronic media? ​

Answer:

Cheetah traveled 120 km to catch deer.

Step-by-step explanation:

Speed of cheetah - 60km/hr

time taken by cheetah - 2min

(therefore sign) distance traveled by cheetah - speed *time =60*2km

=120km

Gɪᴠᴇɴ :-

Principal = Rs.4000

Compound interest = Rs.1324.

Interest is compounded Half yearly . (6 Months.)

ᴛᴏ ꜰɪɴᴅ :-

Rate of interest & Time ? .

Sᴏʟᴜᴛɪᴏɴ :-

→ Amount = Principal + CI

→ Amount = 4000 + 1324

→ Amount = Rs.5324 .

Now, Let us Assume That, Rate is R% Per annum & Time is T years.

→ Amount = Principal[ 1 + (R/100) ]^T

→ 5324 = 4000 [ 1 + (R/100) ]^T

→ (5324/4000) = [ 1 + (R/100) ]^T

→ (1331/1000) = [ 1 + (R/100) ]^T

→ (1331/1000) = ( 100 + R)^T / 100^T

Multiply & Divide by 1000 the LHS now,

→ (1331000) / (1000000) = ( 100 + R )^T / 100^T

→ ( 100 + 10)³ / (100)³ = ( 100 + R )^T / 100^T

Comparing Now, we get,

→ Rate = 10% Per Annum.

→ Time = 3 Years.

But Since Rate of interest was Compounded Half Yearly,

Hence,

→ Actual Rate = 10 * 2 = 20% (Ans.)

→ Actual Time = (3/2) = 1(1/2) Years. (Ans.)

Note :-

When rate is compounded Half-Yearly :- We know that Half yearly Means Half of a year, when we Multiply it with 2 we will get a year .

So we can say that in this case :-

→ Rate is Divided by 2.

→ Time is Multiply by 2 . ( To make it a complete year).

5) The two different types of leaves found in a plant are:

(a)Simple Leaf

When a single lamina is connected to the main stem by a petiole, the leaf is said to be simple. A simple leaf may be incised to any depth but not down to the midrib or petiole. Eg., Guava leaves

(b)Compound Leaf

A compound leaf is a leaf made up of two or more leaflets. In a compound leaf, the midrib of the leaf is branched into different leaflets and is connected by a single petiole. For eg., Pea, palm leaves.

The compound leaves are further sub-divided into the following types of leaves:

•Palmately Compound Leaf

In a palmately compound leaf, the leaflets are attached at the tip of the petiole. Eg., Silk cotton.

•Pinnately Compound Leaf

In a pinnately compound leaf, the midrib of the leaf is divided into numerous leaflets and all connected by a common axis. Eg., Neem.

5) The quality of hydrophytes (aquatic plants) to survive in aquatic habitat are as follows:

(a) In aquatic plants, roots are much reduced in size and their main function is just to hold the plant in place.

(b) In some submerged aquatic plants, leaves are often highly divided, through which the water can easily flow without damaging them.

(c) Some of these plants have narrow and thin ribbon-like leaves.

(d) The mucilaginous secretion of mucilage cells around the body of the hydrophytes provides protection against friction, desiccation, decaying, and microbial injuries.

(e) The stems of some aquatic plants are long, hollow, and light.
