Answer is -300,this is distributive property of multiplication.

Manisha Sawant 6 years, 2 months ago

Sorry, sorry I forgot to write solution. So here is solution. So I said that it is a example of Distributive property so solution : (-30)×[13+(-3)] = [(-30) × 13] + [(-30) × (-3)] so doing the first step :[(-30)×13] = (-390) So now doing second step = [(-30)×(-3)] == 90 = so now it is the final step means last step = (-390) + 90 = -300 So once again : (-30)×[13+(-3)] = [(-30)×13] + [(-30)×(-3)] = [(-30)×13] = (-390) + [ (-30)×(-3)] = (-390)+90 = -300 Bye

ANSWER

How electric bell works

Posted by Nitya Pandey 6 years, 2 months ago

CBSE > Class 07 > Science

2 answers

Nitya Pandey 6 years, 2 months ago

An electric bell consists of an electromagnet, a switch ,an armature like structure that is held by a spring and make and break arrangement with screw and iron bar. When the switch is pressed, the circuit is closed the electric current starts flowing through the wire and coil of electomagnet. Then the electromagnet starts acting like a magnet and it attracts the iron bar towards itself and the hammer attached to the iron bar strikes the gong and the bell rang. When electomagnet attracts iron bar it loses it contact with the screw. When it loses it's contact ,the circuit is broken and current does not flow through it and electromagnet releases the iron bar. Now, when it is released, again it comes in contact with screw and the circuit is closed, now again electromagnet attracts iron bar towards itself . This work of making and breaking of circuit continues till the switch is pressed and the hammer strikes the gong.

Gaurav Seth 6 years, 2 months ago

Electric current flows through the coil when the switch is ON, and the iron core acts as an electromagnet. The iron core attracts the hammer towards it. The hammer hits the bell and produces a sound. The circuit breaks at the screw contact when the hammer moves towards the iron core. At this point, the iron core ceases to be an electromagnet. The hammer is pulled back to its original position due to the spring action of the steel rod, and then touches the contact again to complete the circuit. The circuit is completed and current flows through the coil again, and the hammer strikes the bell again. The process repeats itself and you hear a ringing sound since the hammer keeps hitting the bell, until the switch is released.

.. ... 6 years, 2 months ago

It was the season of the Hilsa fish and the topic of discussion everywhere including the king’s court. The king wanted to put an end to this discussion. He called for a meeting and asked the people if anyone was ready to take up a challenge of bringing a Hilsa fish to the court without anyone talking about it. A courtier Gopal takes up the challenge. He half shaves his head, wears torn clothes and spreads ash on himself. He then gets hold of a Hilsa fish and takes it to the palace. Many saw the fish but did not say a word about it. Instead, they were busy laughing at his style of dressing. When he was stopped at the entrance to the palace by the guards, he sings so loudly that the king asks for him to be sent in. Once inside, everyone including the king asks Gopal about his attire. No one says a word about the fish. Gopal reminds the king about the challenge who congratulates him on his success.

How are tides useful for us?

Posted by Akriti Mishra 6 years, 2 months ago

CBSE > Class 07 > Social Science

2 answers

Manisha Sawant 6 years, 2 months ago

First answer is also correct but might be my ans is little bit different than first. 1 point Definition : Tide : The rhythmic rise and fall of ocean water twice in a day is called a tide. 2.point Now little bit information on tides : It is high tide when water covers much of the shore by rising to it's highest level. It is low tide when water falls to it's lowest level and recedes from the shore. 3. Point : There are two types of tides 1st. Spring tides : the full moon and the new moon day's and when the sun, the moon and the earth are in the same line and the tides are highest. They are spring tides. 2nd. Neap tides : when the moon is in it's first and last quarter, the ocean waters get drawn in diagonally opposite direction's by the gravitational pull of sun and moon resulting in low tides. These are neap tides. 4th. Point : How are the tides caused? Answer : The strong gravitational pull exerted by the sun and the moon on the earth's surface causes the tides. And the importance of the tides you can take from 1st number answer . Bye

.. ... 6 years, 2 months ago

Tides are useful because : 1. Tides help to navigate.' 2. During high tide , the saline sea water is stored in low lying coastal areas. This saline sea water is spread out in the fields and is used to make common salt. 3. During high tide the fished come to the coast. This makes it really easy for the fishermen to catch the fish without having to go into the open water. 4. The energy of tides is used to generate electricity. Tidal power stations have been set up in UK , Japan , France and Canada. 5. Tides help to clear the sediments deposited by rivers on their beds and thus prevents siltation of harbours. ( Siltation is the process by which water becomes dirty as a result of fine mineral particles in the water.)

Do you think that the stone age people were civilized ?

1 answers

.. ... 6 years, 2 months ago

Humankind gradually evolved from early members of the genus Homo—such as Homo habilis, who used simple stone tools—into anatomically modern humans as well as behaviourally modern humans by the Upper Paleolithic.[4] During the end of the Paleolithic Age, specifically the Middle or Upper Paleolithic Age, humans began to produce the earliest works of art and began to engage in religious and spiritual behavior such as burial and ritual.[5][6] The climate during the Paleolithic Age consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures. Archaeological and genetic data suggest that the source populations of Paleolithic humans survived in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover.[7]
