Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
Answer:
Yes.
Explanation:
In this region we see that faulting has occurred. Because the rock strata are not lined up with one another across the entire region, it is clear that the land has faulted and the the two edge blocks have slipped downwards leaving the middle block uplifted or that the middle block has been pushed upwards.
These two types of faulting are called normal faulting and reverse faulting. They are the result of tension and compression stresses, respectively, that pull and compress the rocks creating fractures called faults. If the stress is sufficient, the outer blocks slide downward or the middle block is uplifted.
Answer:
The line between 500 and 600 has an elevation of 550.
Explanation:
The contour interval represents the vertical difference between the contour lines. This is for better orientation on the map, easier calculating of elevation, as well as for an easier understanding of the relief. In this case, we have lines that are set at 500 meters and 600 meters of elevation, but there is also a line between them.
The line between, or rather the contour line between them, can easily be found out as to what elevation it is set on. We have information that the contour interval on the map is 50 meters, so we can do this either by adding 50 on 500 or minus 50 out of 600, anyway we will get the correct result.
500 + 50 = 550
600 - 50 = 550
We get a result of 550, meaning that the contour line between 500 meters and 600 meters is set at 550 meters of elevation.
The sun appears to cross the plane of Earth's equator
when it reaches either one of the "equinox" points in the sky.
At those times, the lengths of day and night are nominally equal
everywhere (except at the poles), and the occasions are marked
as the beginning of Spring and Autumn.
