A Force has a size and a(n)?

2 answers:

6 0

A force is a vector quantity. As learned in an earlier unit, a vector quantity is a quantity that has both magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction.

How does the location of the outer planets explain their composition and characteristics?

Elena-2011 [213]

Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas. Made almost entirely of hydrogen and helium, these planets do not have solid surfaces.

a sound has a frequency of 230 hz. what is the velocity of this sound if it has a wavelength of 46 cm?

lapo4ka [179]

Answer:

V=f×λ

Where,

V is the velocity of the wave measure using m/s.

f is the frequency of the wave measured using Hz.

λ is the wavelength of the wave measured using m.

transform 46 cm in m = 0.46m and there u have it

A spring with a constant k=400n/m shoots a 1. 00kg ball up a frictionless incline after being compressed 0. 150m. what is the ma

Zielflug [23.3K]

The maximum height reached by the ball is 0.46m.

To find the answer, we have to know about the potential energy of a spring mass system.

<h3>How to find the maximum height reached by the ball?</h3>

It is given that,

$k=400N/m\\m=1kg\\x=0.150m\\h=?\\$

We have to find the maximum height reached by the ball.
Thus, we have the expression for potential energy of a spring mass system and that of gravitational field as,

$U=\frac{1}{2}kx^2 \\U=mgh$

Combining both, we get,

$h=\frac{kx^2}{2mg} =\frac{400*(0.15)^2}{2*1*9.8} =0.46m$

Thus, we can conclude that, the maximum height reached by the ball is 0.46m.

What has research determined about the orbit of an electron around a nucleus?

Wittaler [7]

<span>I think the correct answer from the choices listed above is the second option. The research that determined about the orbit of an electron around a nucleus would be that electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model.</span>
