D) convection! here is the reason why :the definition of convection is <span>the concerted, collective movement of groups or aggregates of molecules within fluids (e.g., liquids, gases) and rheids, through advection or through diffusion or as a combination of both of them. So becuase the medal is more convective, this causes it to be heated faster!
Note; this is why we use glass heating plate, so they dont get hot and burn people</span>
A multi-cellular organism is not an exact copy of its parents because the offspring shares genes of both the parents.
<u>Explanation:</u>
- For a multi-cellular organism to reproduce, they require two parents.
- Characteristics are inherited from both the parents. So, an offspring can't b an exact copy of either of its parents.
- When a unicellular organism reproduce, they make an exact copy of its parent as they originate from only one parent.
- Punnett diagram is used to determine what all traits as organism is supposed to inherit from its parents.
- Chromosomes carry the blueprint of life from one generation to another.
- There are 46 chromosomes with 23 inherited from each parents through the process of mitosis. These chromosome makes up 23 pairs all together.
1500m = 1 sec
9000m/1500 = 6
So, it would take 6 sec to go 9000m
Answer:
yes the diagram is correct
Explanation:
Answer:
792 J
Explanation:
The total energy of the ball is E = U + K where U = potential energy = mgh and K = kinetic energy = 1/2mv²
E = mgh + 1/2mv² where m = mass of ball = 2.0 kg, g = acceleration due to gravity = 9.8 m/s², h = height of building = 20.0 m, v = initial velocity of ball = 20.0 m/s.
So, substituting the values of the variables into E, we have
E = mgh + 1/2mv²
= 2.00 kg × 9.8 m/s² × 20.0 m + 1/2 × 2.00 kg × (20.0 m/s)²
= 392 J + 400 J
= 792 J
