Answer:
17 - length of the fork
18 - number of turns
19 - material of the fork
Explanation:
Answer:
a) No. If air resistance is ignored the acceleration of the ball is the same at each point on its flight.
(b). No. As long as the air resistance is negligible, the acceleration of the ball at the top of its flight different from its acceleration just before it lands.
Explanation:
This constant, similar acceleration is called the acceleration due to gravity and it is the acceleration of a body due to the influence of the pull of gravity alone.
Every object on the surface of the earth regardless of its mass is pulled towards the centre of the earth, especially when in flight. Whether flying upwards, or coming downwards, the pull of attraction towards the surface of the earth is the same!
The weight of the African elephant is 58,800 Newtons.
Explanation:
Step 1:
Mass of the African Elephant = 6000 Kg
We need to find the weight of African elephant in Newton.
Step 2 :
Weight in Newtons = Mass of the object × acceleration due to gravity (g)
We know that value of g is 9.8 m/sec²
Hence the required weight = 6000 × 9.8 = 58,800 Newtons
The height of the elephant can reach 4 m. But the weight of any object is nit dependent on the height and hence this information is not required to compute the weight.
Step 3 :
Answer :
The weight of the African elephant is 58,800 Newtons.
