Both hits the ground <u>at the same time</u> because they have <u>same vertical acceleration</u>

<h3>What is vertical acceleration?</h3>
A vertical acceleration is typically one for which the direction of the vector is vertically upward, usually aligned with and opposite to the gravity vector. But this is a descriptive term, not a rigorous or technical term. A car may accelerate along a road and that would generally be assumed to be a horizontal.
The vector perpendicular to this direction, as perhaps a suspension motion over a bump, would be described as vertical even if it is not strictly vertical.
Note that acceleration is defined as the rate of change of the velocity vector. But the gravitation vector, ‘g’, generally vertically downward, is often denoted by what acceleration a mass in free fall (absent air resistance) would experience, i.e. the relationship between mass and weight.

The magnitude of the mass is 20, and the magnitude of the speed is 0.5. Neither one has a direction, since mass and speed are scalar quantities.
Convergent boundaries are caused by the collision of two plates and can originate volcanoes. Transforming boundaries produce fractures by displacement. <em>The correct option is D. Type A boundaries have fewer volcanoes. </em>
----------------------------------------
The crust -the outermost layer of the earth- is divided into many plates that move over the mantle.
These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types:
I. Divergent:
- This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
- The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
- Collision area between two plates.
- Two oceanic plates might collide, or one oceanic plate with a continental one.
- In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
- The thicker and older plate subduces under the other plate.
- Collisions create volcanic arches and continental arches.
III. Transforming.
- The plates slide laterally with each other, and they are usually called faults.
- It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
- No rocky material is either destroyed or formed.
- When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
- The movement breaks the crust and originates pronounced fractures.
In the attached images, we can see
- image A representing transforming boundaries,
- image B representing Convergent boundaries.
Image B is the one that can originate volcanoes because transforming boundaries only produce fractures.
So the correct option would be D.

Answer:
Increases
Explanation:
In the Compton scattering experiment with x-rays,
The change in operation
![\Delta \lambda = \frac{h}{m_oc} [1-cos\theta]](https://tex.z-dn.net/?f=%5CDelta%20%5Clambda%20%3D%20%5Cfrac%7Bh%7D%7Bm_oc%7D%20%5B1-cos%5Ctheta%5D)
Now rest being constant, as \theta increases, cos\theta decreases
Hence, The change in wavelength will increase with the increase in \theta.
Hence, wavelength increases with an increase in the angle of scatttering.
Answer:
D. 0.7 would be wild-type healthy
E. 0.3 would be affected Gg
Explanation:
Using the Punnett square we cross an homozygous male (gg), that is always healthy vs an heterozygous female (Gg). The result is 2 gg individuals, and 2 Gg individuals. Both gg individuals are healthy.
In a population of 1000 Gg individuals, 600 show the Gumball phenotype (unhealthy). It means that from the two heterozygous Gg (from the Punnett square), 1.2 show the unhealthy phenotype.
Again, from the Punnett square we have 4 individuals, that represent the 100%. 1.2 are unhealthy Gg, and represent 30% in F1.
This 30%, is equivalent to 0.3, that is the option E.
100 - 30 % = 70 %. This is 0.7 for healthy wild-type, option D.
