Answer;
The above statement is true
Human impact on one system leads to changes in more of Earth’s systems.
Explanation;
Events can occur naturally, such as an earthquake or a hurricane, or they can be caused by humans, such as an oil spill or air pollution. An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres.
Human impact on one system leads to changes in more of Earth’s systems because things like carbon and methane emissions affect the environment, which affects all plant and animal life.
The statement "Human impact on one system leads to changes in more of Earth’s systems." is a true statement. This is further explained below.
The Earth's five systems
combine to create the surroundings we know.
In conclusion, These systems are on a balance to maintain human existence, meaning that if there is a disruption to one there is a disruption to all.

b. change in mass
c. endothermic change
d. exothermic change
Answer: 71.72 days
Explanation:
This problem can be solved using the Radioactive Half Life Formula:
(1)
Where:
is the final amount of Iodine-131
is the initial amount of Iodine-131
is the time elapsed
is the half life of Iodine-131
Knowing this, let's substitute the values and find from (1):
(2)
(3)
Applying natural logarithm in both sides:
(4)
(5)
Finding :
2 The greater the force applied on an object, the greater it's acceleration
3 You can find the mass of an object if you know it's acceleration and the forces acting on it
4 Force is equal to the product of mass and acceleration
Answer:
1. The mass will change depending on the force.
Explanation:
We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:
F = ma
Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.
In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa

saw, how far out would Mickey have to sit if he wants to apply
the same force onto you that you apply onto him? meters
To apply the same force as the person, the brother have to sit at a distance of 5 m.
What is meant by torque ?
Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.
Here,
Mass of the person, m₁ = 50 kg
Mass of the brother, m₂ = 20 kg
Distance of the person, d₁ = 2 m
For the see-saw to get balanced, the torque applied by the two persons each side must be equal.
τ₁ = τ₂
where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.
So, F₁d₁ = F₂d₂
m₁g x d₁ = m₂g x d₂
m₁d₁ = m₂d₂
Therefore, distance of the brother,
d₂ = m₁d₁/m₂
d₂ = 50 x 2/20
d₂ = 5 m
Hence,
To apply the same force as the person, the brother have to sit at a distance of 5 m.
