26. a megagram = 10⁶ grams while a kilogram = 10³ grams, so the megagram is bigger
28. a mililiter = 10⁻³ liters while a microliter = 10⁻⁶ liters, so the mililiter is bigger
36. 1 meter is equal to 100 centimeters, so the decimal moves right 2 places
37. 1 micrometer is equal to 0.001 milimeters, so the decimal moves left 3 places
38. 1 centimeter is equal to 0.00001 kilometers, so the decimal moves left 5 places
39. 1 micrometer is equal to 10⁻¹² megameters, so the decimal moves left 12 places
40. 1 kilometer is equal to 100000 centimeters, so the decimal moves right 5 places
I think the best answer is b): it contains particles that can settle out.
The definition of suspension is a heterogeneous (that is same in all parts) mixture that contains particles that could undergo sedimentation (settle down) - this definition is close to b). It should not matter whether those particles are nutrients( so A or C are not good answers).
Answer : The correct options are :
2) car A and car B are moving in opposite direction.
3) car A is moving faster than the car B.
Explanation :
From the given position-time graph, we conclude that the car A shows positive slope and the car B shows negative slope. That means the object which has positive slope will move faster as compared to the object with negative slope.
In case of Car A, it is moving towards the positive direction of the position axis whereas Car B is moving towards the negative direction of the position axis which means that both cars are moving in opposite direction.
So, the car A is moving faster than the car B and both cars are moving in opposite direction.
Answer:88.8%
Explanation:
%yield= actual yield/theoretical yield * 100/1
41.9/47.2*100/1= 88.8%
