Physics

Julli [10]2 years ago

Answer:

No, it cannot. The car needs the friction of the surface to drive because the car pushes the surface backwards, and the surfaces makes a reaction force pushing the car forward, and that works because of the friction. In a frictionless surface the tires would rotate in the same place

An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration wo
kenny6666 [7]

Answer:

12.0 m/s²

Explanation:

Newton's second law:

F = ma

Solving for acceleration:

a = F/m

If force is doubled and mass is tripled:

a' = (2F)/(3m)

a' = ⅔ (F/m)

a' = ⅔ (18.0 m/s²)

a' = 12.0 m/s²

lubasha [3.4K]

Answer:

observer bias

Explanation:

Based on the information provided within the question the thing that should concern us the most about Sandi's observations is Observer Bias. This term refers to the tendency of a researcher to see what they want as opposed to what is actually happening. This can be said because of Sandi's belief that McDonald clients are all overweight, by having this belief before actually having come to this conclusion with a series of tests, it might lead her to believe this to be true regardless of what she observes during the experiment.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
