Answer:
h = R/4 = 1.5925 x 10⁶ m = 1592.5 km
Explanation:
The variation in the value of acceleration due to gravity value with respect to the altitude is given by the following general formula:
where,
h = altitude from surface of earth = ?
g = acceleration due to gravity on surface of earth = 9.81 m/s²
R = Radius of Earth = 6.37 x 10⁶ m
g' = acceleration due to gravity at given altitude = g/2
Therefore,
<u>h = R/4 = 1.5925 x 10⁶ m = 1592.5 km</u>
Answer;
B. Seafloor spreading
Explanation;
-Seafloor spreading is the process by which the Earth's lithospheric plates pull apart from each other, creating gaps that are filled with magma from the asthenosphere.
-Alfred Wegener was the scientist who proposed the idea of continental drift. Wegener gave four proofs to support his continental drift hypothesis. These includes;
- Similarities in coastlines
- Fossil records are similar on separate landmasses
- Geologic evidence similarities
- Climatic Change Similarities
The process of sea floor spreading was a confirmation that Wegener's hypothesis was correct.
Answer:
increases.
Explanation:
As a ball falls freely towards the ground, it's kinetic energy increases. If the kinetic energy increases, that means the object hasn't hit the bottom yet. If the ball continues to fall freely towards the ground, the air gives it more pressure, after that the pressure begins to increase.
It expands, increasing in volume. The warmer the water, the more space it takes up, and the lower its density.
The number of outcomes in the compliment of the event are 0.54
<h3>Concept and calculation</h3>
No of strawberry plants in the field = 259259
No of plants that are ready for picking = 142142
so no of outcomes = 142142/ 259259 = 0.54 outcomes
<h3>Understanding of probability</h3>
The area of mathematics that deals with probability is called probability theory.
Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by expressing it through a series of axioms.
Typically, these axioms formalize probability in terms of a probability space, which links a collection of outcomes known as the sample space to a measure taking values between 0 and 1. An event is any defined subset of the sample space.
