Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward
Answer:
Explanation:
As we know that when runner is moving on straight track then the net force on his feet is given as
while when runner is moving on circular track then we have
now percentage change is given as
Answer: force of gravity on the body due to height difference above the earth's surface
Explanation: as you increase the height of a body above ground, you do work against gravity in moving it from a point on the earth's surface to that point. So a body falling has a stored up gravito-potential energy which acts on it downward due to its mass, accelerating it downwards
Answer b): kinetic energy of the body
Explanation: the downward force produces an acceleration of magnitude 9.81m/s2 downwards which means an increasing velocity. This increasing velocity means the kinetic energy of the body is increasing (kinetic energy is proportional to velocity of the body squared)
4.22
Explanation:
The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.
The pH scale expresses the acidity or alkalinity of aqueous solutions.
- The pH scale ranges from 1 to 4
- An acidic solution will have a pH value less than 7
We have given a range of values between 4.22 to 4.40
This implies that the pH values of rainfall in this region falls between these extremes.
The least value 4.22 is the most acidic
The value 4.4 is the the least acidic
The lower the pH value, the more acidic a solution is.

He does not have much endurance since he is new to exercise. This explains best why Guillermo is struggling.
<h3>
What is Endurance?</h3>
- An organism's capacity to exert itself and remain active for a prolonged period of time, as well as its capacity to resist, withstand, recover from, and have immunity to trauma, wounds, or exhaustion, are all examples of endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness). Usually, it is employed in anaerobic or aerobic exercise.
- Depending on the type of activity, "long" can mean anything from minutes for high-intensity anaerobic exercise to hours or days for low-intensity aerobic exercise.
- Unless a person additionally engages in resistance training to offset this effect, training for endurance can impair the ability to exert endurance strength.
