Answer:
Explanation:
As per the Newton's first law of motion,
where "v" is the final speed
"u" is the initial speed
"a" is the acceleration
and "t" is the time taken
Substituting the given values in above equation, we get -
The cart be traveling at a speed of 
by the time it reaches level ground.

Explanation: In his study of pea plants, Gregor Mendel used Cross-pollination method to produce offspring.Therefore the answer is b.cross-pollination, by using parents that had different traits.
Answer:
C. 1,024
The answer can be worked out using 2^pairs of chromosomes
Explanation:
Imagine there were <u>two</u> pairs of chromosomes:
- A paired with B
- C paired with D
A gamete could have the following combinations:
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
Now, Imagine there were <u>three</u> pairs of chromosomes:
- A paired with B
- C paired with D
- E paired with F
A gamete could have the following combinations:
- A + C + E
- A + D + E
- A + D + F
- A + C + F
- B + D + F
- B + C + F
- B + C + E
- B + D + E
Therefore, with three pairs of chromosomes, there are 4 (2³) possibilities
For 10 chromosomes - there are 2¹⁰ possibilities. 2¹⁰ = 1024
1) A. Biological
2) D. Model
3) B. Cold
