| Answer» LET C be the POINT where the ball is. C = 60o (alternate angles) In ABC, tan 60o = AB/BC = 20/x x = 20/ = 20 (/3) = 11.53 m | |

A man is standing on the deck of a ship. which is 10 m above water level. Heobserves the angle of elevation of the topof a hill as 45" and the angle of depressionof the base of the hill as 30". Calculate thedistance of the hill from the ship and theheight of the hill(A) 17.32 m. 27.3 m(B) 18.32 m. 28.3 m(C) 17.89 m. 28.3 m(D) 8.32 m. 29.2 m |
|
Answer» Let a man is standing on the Deck of a ship at point a such that AB = 10 m & let CE be the hillThus, AB = CD = 10 mThe top and bottom of a hill is E and C.Given, the angle of depression of the base C of the hill observed from A is 30° and angle of elevation of the top of the hill observed from A is 60 °Then ∠EAD= 60° &∠CAE= ∠BCA= 30°. (Alternate ANGLES)Let AD = BC = x m & DE= h MIN ∆ ADEtan 60° = Perpendicular / base = DE/AD√3= h/x [TAN 60° = √3]h = √3x……..(1)In ∆ ABCtan 30° = AB /BC[ tan30° = 1/√3]1/√3 = 10/xx= 10√3 m.. …………..(2)Substitute the value of x from EQUATION (2) in equation (1), we have h = √3xh= √3× 10√3= 10 × 3= 30 mh = 30 mThe height of the hill is CE= CD+ DE= 10 +30= 40 mHence, the height of the hill is 40 m & the Distance of the hill from the ship is 10√3 m. |

A ball thrown up vertically returns to the thrower after 6sec.Find:- (a) the velocity with which it was thrown up, (b) the maximum height it reaches, and(C) its position after 4 second |
| Answer» EXPLANATION:Time to reach Maximum height ,t = 6/2 = 3 s.v = 0 (at the maximum height )a = - 9.8 m s-²◆ a) Using, v = u + at, we get0 = u - 9.8 × 3or, u = 29.4 ms-¹Thus, the velocity with which it was thrown up = 29.4ms-¹◆ b) Using, 2aS = v² - u², we getS = v²- u²/2a= 0 - 29.4 × 29.4/- 2× 9.8= 44.1 mThus, Maximum height it reaches = 44.1 m.◆ c) Here, t = 4s. In 3 s, the ball reaches the maximum height and in 1 s it falls from the TOP.Distance covered in 1 s from maximum height,S = ut + 1/2at ²= 0 + 1/2 × 9.8 × 1= 4.9 mTherefore, The ball will be 4.9 m below the top of the TOWER after 4 s.hope it helps u plzz mark as BRAINLIEST | |

Name the group of aniamls that eat only food are... |

Answer» Advanced Dental Care of EnglewoodGuide to Herbivores, Ominvores, and CarnivoresThe food chain includes many different kinds of animals, all of which have specific foods they eat. Three different types of animals exist: herbivores, omnivores, and carnivores. Herbivores are animals that eat only plants. Carnivores are animals that eat only meat. Omnivores are animals that eat both plants and meat. The size of an animal does not determine what it eats. Some of the biggest animals eat only plants, and very tiny animals can be carnivores. An animal’s digestive tract will be specially designed according to the food it eats. An animal’s teeth will ALSO be specially designed depending on the type of food it eats.HerbivoresSome animals eat only plants, making them herbivores. Often, herbivores concentrate their MUNCHING on just the fruits or seeds of plants, ignoring stems, leaves, and roots. Herbivores have special digestive tracts that are designed to handle different types of plants they might eat. Herbivores usually have big front teeth, called INCISORS. These teeth are used to grasp and cut plants. Herbivores also have molars in the BACK, which they use to grind up the plants in their mouths. Herbivores are often very large animals, such as cows, deer, and elk. As you might imagine, it takes a LOT of food to give a large herbivore the energy it needs. That is why herbivores may spend a large part of their day eating. Herbivores can also be medium-sized animals such as sheep or goats. Examples of small herbivores include squirrels and chipmunks. Herbivores need a lot of food to satisfy their hunger.Explanation: |
