Why do the planets orbit the Sun in an elliptical shape?
ki77a [65]

Answer:

That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.

A 4-N object object swings on the end of a string as a simple pendulum. At the bottom of the swing, the tension in the string is
Amanda [17]

Answer:

Explanation:

Given mg = 4N .

m = 4 / g

At the bottom of the swing let centripetal acceleration be a

T - mg = ma

9 - 4 = ma

5 = 4 a  / g

a =  5g / 4

How do you determine the acceleration of an object?
Gelneren [198K]

Are you familiar with any basic calculus? If so, we can just look at this derivative and see what's happening with our units here..

a = \frac{dv}{dt}

Here it shows that acceleration is the derivative of velocity with respect to time. In other words, we can say that:

a=\frac{\Delta v}{\Delta t}

We can read that equation as: "acceleration is the change of velocity divided by the change in time (aka the time interval)."

If you're not familiar with calculus, we can use a simple equation of motion:

v_f = v_i+at

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = observed time interval

We can rearrange this equation to find:

a = \frac{v_f - v_i}{t}

This is the same exact thing we wrote before!

calculate the period of a wave whose frequency is 5 Hertz and whose wavelength is one centimeter give your answer in a decimal f
olga2289 [7]
The period of the wave is the reciprocal of its frequency.

       1 / (5 per second)  =  0.2 second .

The wavelength is irrelevant to the period.  But since you
gave it to us, we can also calculate the speed of the wave.

Wave speed = (frequency) x (wavelength)

                   = (5 per second) x (1cm)  =  5 cm per second
