The correct answer is:
<span>A. electron attraction between electron and nucleus = centripetal force of the orbiting electron

In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus, so option A is the correct one.</span>

How does wheel and axel work​
Andrew [12]

Once the object is moving, the force of friction opposes the force exerted on the object. The wheel and axle makes this easier by reducing the friction involved in moving an object.

Hope it helps!

A rocket is launched upward with a constant acceleration of 165 m/s^2. After 8.00 seconds of ascension a passenger on the rocket
Novay_Z [31]

To solve this problem we will apply the concepts related to the linear kinematic movement. We will start by finding the speed of the body from time and the acceleration given.

Through the position equations we will calculate the distance traveled.

Finally, using this same position relationship and considering the previously found speed, we can determine the time to reach your goal.

For time (t) and acceleration (a) we have to,

t = 8s, a = 165m/s^2

The velocity would be,

u = a*t \\u = 165*8\\u = 1320m/s

Now the position is,

h= \frac{1}{2} at^2

h = \frac{1}{2} 165*8^2

h = 5280m

Now with the initial speed and position found we will have the time is,

h=ut +\frac{1}{2} at^2

-5280=1320t - \frac{1}{2} 9.8t^2

4.9t^2-1320t-5280=0

Solving the polynomian we have,

t = 273.33s = 4.56minutes

Therefore  the rocket will take to hit the ground around to 4.56min

An airplane flies with a constant speed of 720 km/hr. How long will it take to travel a distance of 1440 km? Please show your wo
choli [55]

Answer:

2 h

Explanation:

Velocity =Distance/time ⇒ time = distance/speed

                                                     = 1440/720

                                                     = 2 h

A 5.58 kg object with a speed of 35 m/s strikes a steel plate at an angle of 45.0 degrees with the normal to the plate, and rebo
MAVERICK [17]

Answer:

magnitude of vector is 276.19 kg m/s

Explanation:

The initial momentum is vector of magnitude

5.58 \times 35 = 195.3 (kg m/s)  And driven in a coherent manner with initial vector.

same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.

So, you have 2 momentum vector of  specified magnitude perpendicular to one another.

 The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides

magnitude of vector is  \sqrt{ 195.3^2 + 195.3^2} = 276.19
