Answer:
The term cross-cultural is generally used to describe comparative studies of cultures. Inter cultural is also used for the same meaning.
Explanation:
Given :
- Mass of block = 3.5 kg
- Weight of Block = 3.5 kgf
- Volume of water displaced when body is fully immersed = 1000 cm³
Answer:
For calculating Upthrust on block we will have to first find out Volume of block :
↪Volume of block = Volume of water displaced
↪ Volume of block = 1000 cm³ = 0.001 m³
<h2>________________</h2>
Now, <u>we will calculate the Upthrust on block</u>:
↪ Upthrust on block = Volume of block * Density of water * g
↪ Upthrust on block = 0.001 * 1000 * g
↪ Upthrust on block = 1 kgf
Answer:
i think its student b (d)
Explanation:
it might be student b cuz every action creates an equal and opposite reaction
Answer: 7.8×10^5 J
Explanation:
Total energy = kinetic energy of plane + gravitational potential energy of plane.
Total energy = ((1/2)×m×v²) + (m×g×h)
Here, m is mass of plane, v is velocity of plane, g is acceleration due to gravity and h is height above the ocean.
Now,
Total energy = ((1/2)×m×v²) + (m×g×h)
Total energy = m((v²/2) + (g×h))
Total energy = 850((38²/2) + (9.81×20))
Total energy = 850(722 + 196.2)
Total energy = 7.8×10^5 J
