Poisonings mostly have no taste or smell. Thallium is one of the poisons that are hard to detect. Most of these poisons are always prescribed to many patients and can be misused. We also have to take into consideration thay poisoning attacks our immune system and internal organs. Side effects of poisoning are flue like. So when the individual is feeling ill. nobody is going to think it’s poison at first until about 30 mins to an hour. that’s why it takes so long to be undetected at first. because of the symptoms, smell, taste..... it can really be easy to poison someone

Explanation:
Commonly area is a scalar quantity because there is no need of direction to define and also follow the algebrac summation. When we talk about vector there exist a frame of reference with a certain orogin

Explanation:
Assuming the motion of a simple pendulum, the time period is given by
- ⇒ T = 2π√(L/g)
- ⇒ T₁/T₂ = √(g₂/g₁)
<u>The values we have</u>
- T₁ = 3 s
- g₁ = 9.79 m/s²
- g₂ = 9.82 m/s²
<u>Solving</u>
- T₂ = T₁/√(g₂/g₁)
- T₂ = 3/√(9.82/9.79)
- T₂ = <u>3.004593 seconds</u>
<u></u>
- This many digits are needed because the acceleration is changed by a very small percentage (roughly 2 decimal places)
- So on taking the square root of the ratio of the gravity due to acceleration (2 values), 4 decimal places will be present at the very least
