Answer:
V=972π
The equation I used... V=4/3π(9)^3
The type of energy that an unlit match has is potential energy.
Answer:
Area = 25km² in a century.
Explanation:
Given
Spread Rate = 5m/century
Length of rift = 5000km
Convert to metres
Length of rift = 5000 * 1000m
Length of rift = 5,000,000m
In one century, the additional area to Atlantis = (Rift Length) * (Spread rate) * 1 century
Atea = 5,000,000 m * 5m/century * 1 century
Area = 25,000,000m² in a century
----- Convert to km²
Area = 25,000,000km² * 1m²/1,000,000km²
Area = 25km² in a century.
Hence, the total area of new ocean floor created in the Atlantic each century is 25km²
Answer: d₂ = 170 mGya
Explanation:
the relationship between absonbed 'd' and exposure 'E' is given as;
D(Gv) = F . x (AS/xB)
F is a conversion coefficient depending on medium
so we can simply write
d₁/d₂ = x₁/x₂
Given that;
our x₁ = 60 mAs, x₂ = 120 mAs, d₁ = 85 mGya, d₂ = ?
from the given formula,
d₂ = (x₂d₁ / x₁)
now we substitute
d₂ = (120 × 85) / 60
d₂ = 170 mGya
∴ if 120 mAa is used, the new exposure will be 170 mGya
Answer:
The correct answer is
1. KE Increases, PE Increases, ME Increases
Explanation:
Here, it is essential to define the following concepts.
Kinetic energy is the energy due to motion of an object. The definition of kinetic energy is the energy to accelerate a body from rest to a given velocity. The body retains the kinetic energy as it maintains the attained velocity
KE= 1/2mv^2
From the above definition KE is increasing
Potential energy is the energy stored within a body due to its location in a position or location of higher potential
As an object moves up to higher altitude in a direction opposite to the earth's attractive force, its gravitational potential increases
PE=mgh
From the above definition PE is increasing
Mechanical energy is the sum of potential and kinetic energies that can be used to do work. It is the sum of the potential and kinetic energies stored in the body
ME = PE+KE
Since both PE and KE are increasing then ME is also increasing
