Answer:
Potential energy = 261.633 kJ
Explanation:
The potential energy is the energy stored in an object due to its position above Earth's surface.
The potential energy formula is :
Where 
is the potential energy
m is the object mass
g is the gravity
and h is the height referred to a comparison plane
We start by converting the height in feets to meters
and
Where
N is Newton
J is Joule. Joule is the energy unit
We divide it by 1000 to obtain kJ
Answer:
0.0375 ohms
Explanation:
The resistance of a material is the product of the resistivity of the material by the length of the material divided by its cross-section area.
Mathematically,
resistance= resistivity × length/area
In this case the resistivity of the material is the same, and the length is the same thus, assume a length of 1 unit, the cross-section area is the one changing
In applying the formula,
resistivity is r and length is l=1 unit, find the resistivity the material as;
resistance= resistivity * length /area
0.075=r*1/1.04
0.075=r*0.9615
0.075/0.9615 =r
r=0.078
use the r=0.078 , a length of 1 unit (assumed), and area of 2.08 mm² to find the new resistance
Resistance= resistivity * length /area
Resistance = 0.078*1/2.08
Resistance= 0.078 * 0.4807 = 0.0375 ohms
Point to note here is that the greater the cross-section area, the less the resistance.
Answer:
1. Industrial revolution was initiated or borne through the production of Steel
2. World War 1 led to the development of Tanks
Explanation:
The production of Steel through the Bessemer Process in the middle of the nineteenth century was a major technological development that spurred the Industrial revolution. This invention led to the widespread use of steel in the production of many things including vehicles and airplanes.
During the First World War in 1914, soldiers found the use of just their armaments in battle as not so productive. This led to the development of Tanks in 1915 that would continue moving towards the enemy even when being shot at.
