When you rub the balloons, it will take electrons away, which is negative. So, the balloons are negative
Cesium has the least ionization energy and can donate electrons very easily !
Answer:
C) Rear
Explanation:
For better understanding, let me explain first what actually is the Whiplash injury. It usually occurs in the accidents related to vehicles and cause injury in the neck. It happens because of the very forceful, rapid movement of head and neck forward and backward. So unfortunately if there is a sudden impact of car from the rear and if it's velocity changes from 10 to 15 km/h (as the studies show) it will results in the whiplash injuries. So the correct option here is the third one "<em>rear</em>".
<h2>Given :-</h2>
<h2>To Find :-</h2>
<h2>Solution :-</h2>
As we know that,
<h3>F = ma</h3>
- F is the Force applied
- M is the Mass
- A is the Acceleration
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
F = 20 × 2
F = 40 N
<h3>Hence :-</h3>
Force applied is 40 N
<h2>Know More :-</h2>
- First equation of motion
- v = u + at
- Second equation of motion
- s = ut + ½at²
- Third Equation of motion
- v² - u² = 2as
