The density of aluminium is 2710kgm¯³. Find the mass of an aluminium block with dimensions 2 m x 1.5 m x 1 m. |
|
Answer» - The density of aluminium is 2710kgm¯³. An aluminium block with DIMENSIONS 2 m x 1.5 m x 1 m.To find :- Mass of aluminium block Solution :- Density of aluminium = 2710kgm¯³Length of aluminium = 2mBreadth of aluminium = 1.5mHeight of aluminium = 1mNow,→ VOLUME of aluminium → LENGTH × breadth × height→ 2 × 1.5 × 1→ 3 m³As we KNOW that→ Density = Mass/Volume→ 2710 = Mass/3→ Mass = 2710 × 3→ Mass = 8130 KG Hence,Mass of aluminium is 8130 kg |

Naresh and Sharma went to agra through Yamuna - Expressway. Naresh started the car and accelerated so high that the car was running at 110 km/hwithin 12 seconds. Sharma stopped him from doing so and told him thatoverspeeding on the road is a straight invitation to a life staking situation.Though Naresh wanted the adventure of speeding, he was convinced bySharma.a) Why do you think it is dangerous to drive fast on the road?b) Which values of sharma appreciating?c) Find Naresh’s car speed in m/s.d) What is the acceleration of a car? |
|
Answer» velocity (u) = 0kmhr⁻¹ [Because CAR started from rest]Final velocity (v) = 110kmhr⁻¹.Time (t) = 12 seconds ⇒ (1/300) hours [Convert the units so that there is a common unit. To convert ].a) Why do you think it is dangerous to drive FAST on the road? b) Which values of Sharma appreciating? c) Find Naresh’s car speed in m/s. d) What is the acceleration of a car?a) Yes, it is dangerous to drive fast on the road because if we accelerate faster than the speed limit, the chances of having an accident are higher.b) Sharma was careful, cautious, attentive, alert and vigilant . He had a lot of critical THINKING skills.c) Naresh's car was RUNNING at a speed of 110kmhr⁻¹. In order to convert kmhr⁻¹ into ms⁻¹, divide the speed value by 3.6.d) We know that:PLUG in the values. |

A piece of copper of mass is 8.9 kg has a volume 0.001 m³. What is the density of copper? |
|
Answer» - A PIECE of copper of mass is 8.9 kg has a VOLUME 0.001 m³.To find :- DENSITY of copperSolution :- Mass of copper = 8.9 kgVolume of copper = 0.001m³As we know→ D = M/VWhere " D " is density, " M " is mass and " V " is volume.According to the given condition→ Density = 8.9/0.001→ Density = 89/1 × 1000/10→ Density = 89 × 100→ Density = 8900kgm¯³Hence,Density of copper is 8900kgm¯³ |
