6 0

Answer:

  30.22°.          

Explanation:

Given that

height of the bridge ,h= 12 ft

The distance of the lake from bridge ,L= 7 m

 Lets take angle = θ

Now by using diagram

We can say that

tan\theta =\dfrac{L}{h}

tan\theta =\dfrac{7}{12}

tan\theta=0.583

\theta=30.22^{\circ}

That is why the angle will be 30.22°.

Which of the following is inversely proportional to the gravitational force between two masses?
Mrrafil [7]
It is D, the distance between each object squared. We get this from solving for the force of gravity, which is

F = G((m1*m2)/(r^2)).

Here, you can see that the masses of the two objects are divided by their total distance apart from each other (r) squared.

How did Niels Bohr change the atomic model based on his experimental results?
Alexus [3.1K]

Answer: Find the answer in the explanation

Explanation:

Bohr postulated that :

1.) Electrons revolve in specific circular orbits around the nucleus and these orbits can be represented by the letters K, L, M, N.

2.) Electrons revolving in a particular orbit are in a stationary state. They can neither gain energy nor loose energy. 3.) But if an electron jumps from an higher orbit to a lower orbit it will emit energy in the form of radiations. Also if an electron jumps from lower orbit to a higher orbit it excites and absorbs energy in the form of radiations.

4.) Neil Bohr experimental findings about angular momentum of an electron shows more light on the stability of atom and the line spectrum of hydrogen atom

A car traveling on the highway at 15 m/s accelerates at 3.0 m/s2 for 5.0 s. What is its final velocity?
Nataly_w [17]

Answer:

The answer to your question is:  vf = 30 m/s

Explanation:

Data

vo = 15 m/s

a = 3.0 m/s²

t = 5 s

vf = ?

Formula

vf = vo + at

Substitution

vf = 15 + (3)(5)

vf = 15 + 15

vf = 30 m/s
