Answer:
.000828 j
Explanation:
Work = F * d
.0069 N * .12 m = .000828 j
Answer:
The lid becomes tighter
It becomes tighter because metals have a lower heat capacity than glass meaning their temperature drops (or increases) much faster than glass for the same energy change. So in this example, the metal will contract faster than the glass causing it to be more tighter around the glass.
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.
Answer:
as we move higher altitudes force of gravity us decreases
