.4. Find the area of a right triangle whose base is 1.2 m and hypotenuse 3.7 m. |
|
Answer» Answer: 2.1 m^2 Step-by-step explanation: Here, Base of that TRIANGLE is 1.2 m and hypotenuse is of length 3.7 m. As it's a right ANGLED triangle Pythagoras theorem can be applied. Using Pythagoras theorem: ⇒ base^2 + height^2 = hypotenuse^2 ⇒ ( 1.2 m )^2 + height^2 = ( 3.7 m )^2 ⇒ 1.44 m^2 + height^2 = 13.69 m^2 ⇒ height^2 = 13.69 m^2 - 1.44 m^2 ⇒ height^2 = 12.25 m^2 ⇒ height^2 = ( 3.5 m )^2 ⇒ height = 3.5 m We KNOW area of right angled triangles is given by half of the product of its height and base. ⇒ Area of this triangle = 1 / 2 * 3.5 * 1.2 m^2 = 3.5 * 0.6 m^2 = 2.1 m^2 |

♥️Hello FriendS! ♥️_________________________________________Q.1 Answer the questions in Breif :- a. A Plastic Cube is Released in water, will it sink or come to the Surface of water? b.) Why do the load carrying heavy Vehicles have Large numbers of wheels? c.) How much pressure do we carry on our heads ? why don't we feel it ? |
|
Answer» ━━━━━━━━━━━━━━━━━━━━ Q.1 Answer the questions in Breif :- a. A Plastic Cube is Released in water, will it sink or come to the Surface of water? Ans- It is decided by a CONCEPT of Buoyancy that whether a SUBSTANCE floats or SINKS in water. Buoyancy or upthurst means the upward force exerted by the liquid on any particular object immersed in it. It depends upon the density of the body.
The plastic is the light weight substance and have density less than water, thus it will float on water. This phenomenon has become the biggest reason for ocenic water pollution. ﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏ ✍ b.) Why do the load carrying heavy Vehicles have Large numbers of wheels? Ans- The load carrying heavy vehicles have a large weight thus, they exert a high pressure to the ground. This can even break the ROADS and can cause accident, to avoid this ,they have large no. of wheels which increase the surface AREA in contact with the ground, and the weight will be equally distributed and hence reducing pressure. It is because the pressure is inversely proportional to area of contact. This can be better understood by the formula for pressure i.e. Thus, the load carrying heavy vehicles are provided with large no. of wheels. ﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏﹏ ✍ c.) How much pressure do we carry on our heads ? why don't we feel it ? Ans- The atmosphere is around us i.e. the layer of air. As we know that gases also exerts pressure, hence we are carrying the entire atmospheric pressure of 1 atm i.e. 10^5 pascals. But, isn't it strange, that we are not able to feel anything? It is because of the blood that is flowing inside our body also exerts the same pressure in an outward direction and the atmosphere in the inward direction. Thus these pressure balances each other and have no effect on our body. ━━━━━━━━━━━━━━━━━━━━ |

Answer» Answer: [Figure in the attachment] Given –
To Find –
Solution – We know that the length PQ is 200m. Hence, AB = 200 m. Now, height of cloud = AB + BC. We know the length of AB, We need to find BC. In ∆ QBC, tan ∅ = Perpendicular/Base Hence, tan 30° = BC/QB. ➸ tan 30° = X/QB [Assumed BC as x] ➸ 1/√3 = x/QB ➸ QB = √3 x ....k1) In ∆ QBD, tan ∅ = Perpendicular/Base Hence, tan 60° = BD/QB ➸ √3 = (200 + AD)/QB ➸QB√3 = 200 + AD ➸ QB = (200 + AD)/√3 ....(2) Equating equation 1 and 2, ➸ QB = √3 x = (200 + AD)/√3 ➸ 3 x = 200 + AD [AD = 200 + x] ➸ 3 x = 200 + 200 + x ➸ 3 x = 400 + x ➸ 3 x - x = 400 ➸ 2 x = 400 ➸ x = 400/2 ➸ x = 200 Hence, Height of cloud = 200 + x = 200 + 200 = 400 m. |
