What holds the positively charged metal ions together within a metallic bond?

Physics
1 answer:
enot [183]3 years ago
4 0

Answer:

The electron cloud

Explanation:

Metallic bonds result from interaction of positively charged metal ions with free valence electrons which now forms an electron cloud around the metal ions. Electrostatic interaction between the metal ions and the electron cloud holds the metal ions together in the metallic bond.

A 200 kg golf cart strikes a 1500 kg car with 1000N of force, bringing its velocity from 5 m/s to 0 m/s in 1 second. How much fo
tensa zangetsu [6.8K]
<h2>Answer:</h2>

1000N

<h2>Explanation:</h2>

From Newton's third law of motion, for every action there is an equal and opposite reaction. In other words, when two bodies are in collision, the forces acting between these bodies are equal in magnitude and opposite in direction.

In the case presented in the question, the bodies are the <em>golf cart</em> and the<em> car. </em> During collision, the <em>golf car</em> strikes the car with a 1000N of force (that is the <em>action</em>). Consequential of this, though in the opposite direction, the <em>car </em>will apply an equal force of 1000N (that is the <em>reaction</em>) on the <em>golf car.</em>

<em></em>

Therefore the car applied a force of 1000N on the golf cart.

(0) Calculate the momentum of the vehicle when it moves at the maximum speed of 90 km/h with load of 3000 kg
Westkost [7]

Answer: 75000kg*m/s

Explanation:

p=mv

where;

p = momentum

m = mass = 3000kg

v = velocity = 25m/s

--------------------------------------------------------------------------------------------------

The first thing we need to do is convert 90km/h to m/s. Our conversion factors here are: 1km = 1000m and 1h = 3600s

90km/h(\frac{1000m}{1km})(\frac{1h}{3600s} )=25m/s

Plug your values in the formula:

p=(3000kg)(25m/s)\\p=75000kg*m/s
