Answer:
Both are examples of negative feedback regulation.
Explanation:
The maintenance of the homeostasis in the body is controlled by the the feedback regulation of the body. Two main types of feedback regulation are positive regulation and negative regulation.
The negative regulation occurs when the final product of the reactions inhibits the further secretion of that product. In the given examples of aldosterone and calcium mechanism, the secretion of aldosterone and calcium decreases as the normal levels are acheived in the body.
Thus, the answer is both are examples of negative feedback regulation.
Answer:
plug it into your calculator
Explanation:
Kinetic energy = KE = Joules = J
KE= 1/2mv^2
90,000 = 1/2 m (12^2)
180,000 = m (144)
m = 180,000 / 144
Answer:
We conclude that the change in momentum of a body is equal to the impulse experienced by a body.
Explanation:
Considering the equation
F • t = m • Δ v
Here,
m • Δ v is basically a change in momentum of a body which is equal to the mass of the object multiplied by the change in its velocity.
Also,
- F • t is called the impulse of the object.
In the formula, it is clear that the impulse experienced by a body during the collision is basically a change in the momentum of the body.
In other words, the change in momentum of a body is equal to the impulse experienced by a body.
Therefore, we conclude that the change in momentum of a body is equal to the impulse experienced by a body.
The direction of an arrow shows the direction of the force, and the length of the arrow indicates the amount, or size, of the force.
