Although the sample is not shown in this question, we can conclude that it would be reasonably easy for David to provide evidence of the color, consistency, temperature, and texture of the soil.
<h3 />
<h3>What are these properties an example of?</h3>
These are all examples of the physical properties of a sample. Since we cannot see the sample that David is using, it would be safest to assume that he would have no trouble providing evidence as to the physical properties of the soil, the:
- Color
- Consistency
- Temperature
- Texture
are all examples of this.
Therefore, we can confirm that David can provide evidence of the color, consistency, temperature, and texture of the soil.

The correct answer is the correct answer is A
Answer:
0.198 m/s
Explanation:
m1 = 0.7 kg, u1 = 0.15 m/s,
v1 = 0.08 m/s
m2 = 0.5 kg, u2 = 0.1 m/s
Let the speed of 0.5 kg is v2 after the collision.
By using the conservation of momentum
Momentum before collision = momentum after collision
m1 u1 + m2 u2 = m1 v1 + m2 v2
0.7 x 0.15 + 0.5 x 0.1
= 0.7 × 0.08 + 0.5 × v2
0.099 = 0.5 v2
v2 = 0.198 m/s
The answer is D. Exerts a gravitational pull on the star it orbits.
