Answer: The first one: 2.50 x 10^-5
Explanation:
Answer:
<h2>6426000 mg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
63 mL = 63 cm³
We have
mass = 102 × 63 = 6426
But 1 g = 1000 mg
6426 g = 6426000 mg
We have the final answer as
<h3>6,426,000 mg</h3>

Answer:
1. A
2. D
3. E
4. B
5. C
Explanation:
1. Plants are known as producers since they produce energy for themselves through photosynthesis.
2. The rabbit is a primary consumer since it’s herbivore and only feeds on producers for energy.
3. The tiger is a carnivore, and preys on other consumers for energy.
4. A human is an omnivore since it can gain energy from both producers and consumers.
5. Bacteria are know as decomposers since such category of organisms break down other organisms to gain energy.
F = MA A = change in velocity Constant velocity = no change in velocity = Zero acceleration Ignoring friction, 5 kg * 0 m/s^2 = 0 N Therefore, there is no force (0 N) required to keep the object in motion if the surface friction is ignored.
I hope my answer has come to your help.
