A parallel force is a force that acts in the same direction as the motion of an object. The best explanation for a parallel force would be Newton's laws of motion. According to Newton's first law, an object at rest will remain at rest, and an object in motion will continue in motion in a straight line at a constant speed unless acted upon by an unbalanced force.

Therefore, a parallel force, acting in the same direction as the motion of an object, will increase or decrease the speed of the object but not change its direction of motion.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. A parallel force will cause acceleration, that is a change in the velocity, of the thing. The greater the force, the greater the acceleration, and the smaller the force, the smaller the acceleration.

This means that if an object is already moving in a certain direction and a parallel force is applied, the object will accelerate in that direction.

By bouncing into (or out of) a stretched position while using the extended muscles as a spring to pull you out of the stretched position, you are stretching or "warming up."

For instance, repeatedly bouncing down to touch your toes. Stretching in this way is thought to be harmful and risky for injuries. In that it is movement-based, ballistic stretching is comparable to dynamic stretching. You strive to extend a bodily part's range of motion rather of extending it all the way to the limit.

Reaching over to touch your toes and bouncing to enhance range are two examples of ballistic stretching. Due to the risk of injury and lack of benefit compared to other, safer forms of stretching like PNF and dynamic stretches, this sort of stretching is rarely advised.

Answer:

Question 7 is "Weight force down is greater than the air drag"

Question 8 is "600 N"

Explanation:

Question 7: When looking at the forces acting on the skydiver it's important to look at what force is larger, in this case, it's the weight. If two forces are acting in opposite directions, then the body will move in the direction of the force that has a larger value, 735 N.

Question 8: When the question tells you that the forces should be balanced, it means that they should turn out to equal zero if you were to subtract the forces, or you can think of it as trying to get the side that has a smaller number to be equal to the number that is greater. Since the question specifically says the parachute will ADD drag to the equation, you solve this one by asking yourself "What number + 135 will equal 735?" This ends up being 600 N.

Hope this helps!

Velocity of an object depends on its displacement and its direction. Displacement is the minimum distance between the starting and the end point. Velocity is the  rate of change in displacement.

Velocity can be calculated by displacement/ change in time. Relative velocity will be either equal or less than the relative speed, because speed is either greater than or equal to displacement. Also it is a vector quantity, so it also depends on the direction of the movement.

The magnitude depends on the magnitude of the displacement. The direction will be the direction of the resultant vector quantity. It is usually as the same as the direction of movement.

So velocity depends on the magnitude and direction of displacement.

Answer:

The greater the object's surface area, the more air resistance it encounters.

Explanation:

Terminal velocity is the point at which the force of air resistance is equal to the force of gravity acting on an object. An object with a greater surface area will encounter more air resistance and therefore have a lower terminal velocity.

The greater the object's surface area, the more air resistance it encounters. Hence, its velocity decreases with increasing surface area.

Velocity is a physical quantity that measure the distance covered by an object per unit time. Velocity is the rate of speed and it is a vector quantity. Velocity of an object is affected by its mass, physical state, surface area, temperature etc.

As the mass increases, the velocity of a a falling object will be greater because, the gravitational force towards the massive object is greater and it falls rapidly.

As the surface area of the object increases, the air resistance that it encounters also increases. This air resistance acts as an opposition and decreases its velocity.

Cellular respiration is like a battery charger if ATP is like a battery. Substrate-level phosphorylation and oxidative phosphorylation are the two mechanisms used by our cells to produce ATP.

Plants possess three. They generate ATP when photosynthesis is taking place by using solar energy. During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.

Glyceraldehyde-3-phosphate 1,3 diphosphoglycerate results in the first generation of ATP. Second, when phosphoenolpyruvate breaks down into pyruvate, ATP is created. For each of the two 3-phosphate molecules, these processes happen twice. Thus, during glycolysis, a total of 4 ATPs are created.

For instance, if you measure a substance's weight in the lab and come up with a reading of 3.2 kg when the true or actual weight was 10 kg, your reading is inaccurate. Your measurement in this instance is quite far from the value that is already known.

The more traditional expression is "accuracy of measurement," which is defined as "... the degree to which the outcome of a measurement agrees with the true value" on an international scale.
