Answer:
Their experimental design lacks control group
Explanation:
Based on what I read, the scientists don't have a control group as one of the main groups thus they cannot, in scientific sense, say that the medicine is better or worse. You always need a control group receiving no intervention because then we can compare groups and assess the effectiveness of that intervention (in our case if we had control group vs people who received the medicine, we could see if the people who received the medicine had improved condition etc when compared to participants who did not receive anything)
Answer:
Explanation:
They substituted the value of M₁.
∑F = ma
M₁ a = T₁ - F
M₁ a = T₁ - Nμ
M₁ a = T₁ - M₁g μ
Given that M₁ = 2, g = 9.81, and μ = 0.25:
(2) a = T₁ - (2) (9.81) (0.25)
Answer:
10kg
Explanation:
Weight is "how much does gravity drag this down".
Mass is "how much matter is there here".
The relation is:
where is the weight, is the mass and is the gravitational acceleration (roughly equal to 10N/kg on Earth).
From the task we know that:
So let's input it into the relation:
