As an object rises WITH air resistance, the acceleration is larger in size than g, because both gravity and air resistance

will be causing a downward acceleration. As the object FALLS with air resistance, the acceleration will be smaller in

size than g, because gravity and resistance will be opposing each other. Because of the smaller acceleration being

applied over the same distance, the return speed will be slower than the launch speed.

If a skydiver jumps out of a plane which force is greater gravity or air resistance?

Initially, gravity is greater than air resistance, causing the skydiver to accelerate downwards. As the skydiver picks up speed, air resistance increases until it eventually balances out with gravity, leading to a constant speed called terminal velocity.


What force cause parachute to slow down or speed up?

Air resistance, also known as drag force, is the force that slows down a parachute. By increasing the surface area of the parachute, more air resistance is created, slowing down the descent. Gravity acts as the force causing the parachute to speed up initially before air resistance counteracts it.


Two stones of unequal masses are thrown vertically up with the same velocity . what will happened?

The stone with greater mass will reach a lower maximum height compared to the stone with less mass due to the greater gravitational force acting on it. Both stones will eventually fall back to the ground with the same velocity they were initially thrown with.


How is cumulative effect of gravity and air resistance related to an objects termianl velocity?

The cumulative effect of gravity and air resistance determines an object's terminal velocity. Initially, gravity accelerates the object, while air resistance acts in the opposite direction. As the object gains speed, air resistance increases until it becomes equal in magnitude to the force of gravity. At this point, the net force on the object is zero, resulting in a constant terminal velocity where the forces are balanced.


What is displacement of the point of a wheel initially in contact with the ground when the wheel rolls forward one-half revolution.radius of the wheel is R?

The displacement of the point initially in contact with the ground when the wheel rolls forward one-half revolution is equal to half the circumference of the wheel. The circumference of a circle is given by 2πr, where r is the radius of the wheel. Thus, the displacement is πR.

A 6.50 mu F capacitor that is initially uncharged is connected in series with a 4500 Omega resistor and a 500 rm V emf source with negligible internal resistance Just after the circuit is completed?

Any capacitor that is initially uncharged, when presented with a step change in voltage, will have an instantaneous resistance of zero ohms. As a result, the instantaneous current with a circuit involving 4500 ohms and 500 volts will be about 0.111 amperes. It does not matter what the capacitance is.The stated voltage in the question is unclear, so 500 volts was assumed for the answer.


Why initially capacitor taking more current?

Consider the instantaneous DC analysis. Initially, the capacitor has zero resistance. You apply a voltage and current is controlled by other resistive elements alone. As the capacitor charges, its effective resistance rises. This adds to the net resistance in the circuit, reducing current. At full charge, the capacitor has infinite resistance, so there is no current. Remember that the equation for a capacitor is dv/dt = i/c.

Why is Japanese written vertically?

Japanese can be written both vertically (縦書き, tategaki) and horizontally (横書き, yokogaki), formal Japanese writing is usually written vertically with lines moving from right to left. The Japanese writing system takes its roots from the Chinese writing system, and as such was initially oriented vertically. 横書き was introduced later with the introduction of western language dictionaries, the reason being because having both vertical and horizontal text in one book was rather impractical and made it more difficult to use.


How does acceleration due to gravity of the large ball compare to the smaller ball?

If you let two balls fall, initially the velocity will be the same. A small (and light) objects will eventually fall slower, because of increased air resistance. But if you can ignore air resistance - distances are short, or you do the experiment in a vacuum - acceleration will continue to be the same - on Earth, about 9.8 (meters per second) per second.If you let two balls fall, initially the velocity will be the same.

What is the force exerted by the Tacoma narrows bridge?

the force was torsion. the wind made it bend like silly puddy ************** The force exerted TO the Tacoma narrows bridge was initially the wind resistance. The wind resistance caused the whole bridge to act as a system with forced vibration with damping.
