Answer:
<u>Box 1</u>
Explanation:
Formula we are using :
<u>Force = mass × acceleration</u>
or
<u>mass = Force / acceleration</u> (since mass needs to be found)
=============================================================
Box 1 :
⇒ mass = 5 N / 5 m/s²
⇒ mass = 1 kg
=========================================================
Box 2 :
⇒ mass = 5 N / 0.75 m/s²
⇒ mass = 5 × 4/3 = 20/3 kg
⇒ mass = 6.67 kg
===========================================================
Box 3 :
⇒ mass = 5 N / 4.3 m/s²
⇒ mass = 50/43 kg
⇒ mass = 1.16 kg
===========================================================
On comparing Box 1, Box 2, and Box 3, we understand that <u>Box 1</u> has the smallest mass
Answer: Yes, it is possible.
Explanation: In order to explain we can show that circular movement has a centripetal acceletarion and the speed is constant, so the centripetal accelaration changes the direction of the vector velocity in order to keep the circular trajectory.
1. Archaeological Dating. Carbon-14 is often used to find the age of a substance many years old.
2. In the use of x-rays and cat scans. X-Ray technicians often inject radioactive iodine in ones system to increase the contrast between soft tissue and bone on an x-ray image.
3. Smoke detectors: Americium is often used in smoke detectors because it is very sensitive to burning carbon dioxide.
The effective acceleration or deceleration due to gravity depends on the inclined angle of the track relative to ground; the steeper the slope is the greater the effective acceleration.
