How does acceleration affect velocity

Answers

Answer 1

Answer: you get a repetative increase in velocity

Answer 2

Answer: Well the rate at which velocity changes with time is called Acceleration. Accelerating is a measure of how quickly the velocity is changing. If velocity doesn't change, there is no acceleration.

Every 6 seconds a pendulum completes one cycle. What are the period and frequency of this pendulum?

Answers

The period is the time it takes any repeating process
to complete one cycle. You just told us what it is for the
pendulum . . . 6 seconds.

The frequency is the reciprocal of the period. For the pendulum,
that's

1 / (6 sec) = (1/6) per second = 1/6 Hertz .

The period is 2.4 seconds and the frequency is I believe 1/6 I'm not entirely sure since I don't think this question has enough information.

1. What could be the energy of a flying aeroplane?

2. Is work the same as power?

Answers

Explanation:

The total energy of an aircraft flying in the atmosphere can be calculated using equation 1. [2]

E = ½ m v2 + mgh

A Boeing 737-300 has a maximum takeoff weight of 5.65 × 104 kg, a cruise altitude of h = 10,195 m, and cruise speed of 221 m/sec. Inserting these numbers into the above equation, we obtain 7.03 GJ for the energy at cruise conditions. [3] However, the engines mounted onto the wings of the plane are required to provide additional energy per time, power, in order to keep the aircraft flying at a constant altitude and speed

Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

A bird flies 2.8 due west and then 2.7 due north. Another bird flies 2.7 due west and 2.8 due north. What is the angle between the net displacement vectors for the two birds?

Answers

Assume a 2D plane and both the birds start at origin. +X is east, -X is west, +Y is North, -Y is South.
So, after travel position of bird1 is (-2.8, 2.7) and bird2 is (-2.7,2.8);
slope of bird1 is 2.8/2.7
slope of bird2 is 2.7/2/8
Now we have two solpes b1 and b2
formula = (b2-b1)/(1+b1*b2);

What is the period of vibration for a wave with a frequency of 100 hertz?

Answers

The number of back-and-forth vibrations in a unit of time is an object's frequency. A complete back-and-forth vibration is one cycle. 1 Hz is one vibration or wave cycle per second!

Answer:

100 seconds
