It is called polarizability. A dipole moment is needed for the molecule or atom due to the distortion of the electron cloud. A dipole is a pair of electrical charges that have opposite signs and during a dipole moment two charges separate.

Stopping distance of vehicles When brakes are applied to a moving vehicle, the distance it travels before stopping is called sto
DochEvi [55]

Answer:

Stopping distance = 40m

Explanation:

Given the following :

Initial speed of vehicle before applying brakes = 72km/hr

Converting km/hr to m/s:

72km/hr = [(72 * 1000)m] / (60 * 60)

72km/hr = 72,000m / 3600s

72km/hr = 20m/s

Deceleration after applying brakes (-a) (negative acceleration) = - 5m/s^2

From the 3rd equation of motion:

v^2 = u^2 + 2as

Where v = final Velocity ; u= Initial Velocity ; a = acceleration and s = distance

Final velocity when the car stops will be 0

Therefore ;

v^2 = u^2 + 2as

0 = 20^2 + 2(-5)(s)

0 = 400 - 10s

10s = 400

s = 400/10

s = 40m

Therefore, the stopping distance of the car = 40 meters

What is the power generation in a machine that produces 76 j in 3.7s
ICE Princess25 [194]
Power is the ratio between energy and time:
P= \frac{E}{t}
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
P= \frac{76 J}{3.7 s} =20.5 W

Mariner 10 was the first to visit this planet in 1974. what is this planet?
hram777 [196]
<h2>Answer: Mercury</h2><h2 />

The Mariner 10 probe was launched by NASA on November 3rd, 1973, with the purpose of exploring the characteristics of two planets in the solar system that were closest to the Sun, Mercury and Venus.  

In addition, it was launched to explore the atmosphere and surface of both planets and <u>prove that it was possible to use gravitational assistance</u> (also called <u>slingshot effect</u>, a special orbital maneuver in order to use the gravitational field energy of a planet or massive body to accelerate or slow the probe and change the direction of its trajectory) in long interplanetary trips to save fuel.  

In this case, <u>Mariner 10 first arrived at Venus</u> and succeded in using its gravitational field to accelerate its trajectory towards Mercury.
