29. “भाग्य पर इठलाऊँ" का कौन अर्थ सही है ? (A) भाग्य पर नाराज होना (B) भाग्य पर गर्व करना (D) भाग्य पर अफसोस करना (C) भाग्य पर भरोसा करना​

Answer:

A) Downwards.

B) Because BC is in the same direction as the direction of field line. Force is minimum when the direction of current in the conductor is the same as that of the magnetic field. BC will not contribute as the force on this part of the coil will be cancelled by the force on DA.

Explanation:

a) When battery is switched on, the current flows through the coil ab from a to b and magnetic field is north to south. So, by Fleming's left hand rule, downward force is applied on ab.

b) Because current in arm bc travels in the same direction as the magnetic field lines. When the direction of the magnetic field and current are parallel. The resultant force on the current carrying conducter will be zero. Hence, current in arm bc does not countribute to the movement of coil.

Answer:

44.5

Step-by-step explanation:

The number 89 is called the numerator or dividend, and the number 2 is called the denominator or divisor.

The quotient of 89 and 2, the ratio of 89 and 2, as well as the fraction of 89 and 2 all mean (almost) the same:

89 divided by 2, often written as 89/2.

Thus, the answer comes as 44.5

Step-by-step explanation:

Given that b=3h

Area=21×bh

Area=21×(3h)h

Area=21×3h2

Given that 

⇒58×21×3h2=783

⇒3h2=27

⇒h2=9

⇒h=300m

⇒b=900m

Step-by-step explanation:

(Use a graph paper for this question.) The daily pocket expenses of 200 students in a school are given below:

Pocket expenses (in Rs) 0−5 5−10 10−15 15−20 20−25 25−30 30−35 35−40

Number of students (frequency) 10 14 28 42 50 30 14 12

Draw a histogram representing the above distribution and estimate the mode from the graph.
