Answer:
28.9 seconds
Explanation:
Convert km/hr to m/s.
83.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 23.2 m/s
16.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 4.56 m/s
Given:
Δx = 400 m
v₀ = 23.2 m/s
v = 4.56 m/s
Find: t
Δx = ½ (v + v₀) t
400 m = ½ (4.56 m/s + 23.2 m/s) t
t = 28.9 s
Answer : The temperature of the gas is, 43.4 K
Explanation :
The expression used for work done will be,
where,
w = work done = 200 J
n = number of moles of gas = 0.40 mol
R = gas constant = 8.314 J/mole K
T = temperature of gas = ?
= initial volume of gas = X
= final volume of gas = 
Now put all the given values in the above formula, we get :
Thus, the temperature of the gas is, 43.4 K
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
Answer:
Option D, The claims may be biased, is the right answer.
Explanation:
Option D is the correct answer because the primary motive of a company is to earn more profit and it can misguide the consumer by making false and biased claims. Therefore, the evaluation of the claims is the responsibility of the buyers which help them to buy the product beneficial to them. For example, if a product claims that it will glow your skin within seconds then it is the awareness or activeness of the consumer to evaluate such claims which are written on the label and cross verify the ingredients that are used in it because such claims can be false to sell the product.
