B,  only when a nonzero net force is applied, this means that the force is unbalanced, an object in motion stays in motion unless acted upon by an unbalanced force.

THE RIGHT ANSWER WILL RECEIVE A BRAINLESS AND POINTS AND THANKS!!!
poizon [28]

Answer:

391.67Hz

Explanation:

The fundamental frequency formula in string is expressed as;

Fo = V/2L

V is the velocity of the wave = 329m/s

L is the length of the string = 42cm = 0.42m

Substitute

Fo = 329/2(0.42)

Fo = 329/0.84

Fo = 391.67Hertz

Hence the  fundamental frequency of a mandolin string is 391.67Hz

Dante is leading a parade across the main street in front of city hall. Starting at city hall, he marches the parade 4 blocks ea
Yuliya22 [10]

Answer:

The displacement is 6.71 [m} and the angle is 63.4° to the north of east

Explanation:

Using a sketch showing Dante's displacement, we can find each of the points Dante moves through. First, it moves 4 blocks east, the new coordinate (4.0), then moves 3 blocks south and we will get the new coordinate (4, -3). Then Dante moves 1 block west, thus the new point is (3, -3). And finally it moves 9 blocks north where the new coordinate in and gets -3 - (-9) = + 6.

The displacement can be found using the equation for the straight line.

d= \sqrt{(x_{1}-x_{0} )^{2} +(y_{1}-y_{0} )^{2} } \\d= \sqrt{(3-0 )^{2} +(6-0 )^{2} } \\\\d=6.71 [m]\\

We can realize that the triangle formed is a right triangle, therefore we can find the angle of the displacement.

tan(a)=\frac{6}{3} \\a=tan^-1(2)\\a=63.4[deg]

Why is the gravity on Earth greater than the gravity on Mars? (HELP will mark as Brainliest!!!)
steposvetlana [31]

<em>Hey There!!</em>

<em>I think the answer is:</em>

<em>B). </em><em>Mars has less mass than Earth. </em>

Explanation:

<em>Because, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth's gravity due to the planet's smaller mass.</em>

<em>P.S </em><em>Tell me if this is wrong....</em>

<em />GoodLuck!!<em />
