Answer:
C. Seed C germinates more with more water.
Explanation:
In this experiment, the seed (seed C) was subjected to certain conditions and the result is what has been presented for us to make an inference.
We observe the following from the information given us:
I. the same seeds were used for the experiment
II. the same heat medium of 24 °C was used for all the seeds
III. different daily amount of water was supplied the seeds - 90 ml, 50 ml and 10 ml
From the experiment, we have this result:
the seed that was watered with 10 ml daily did not sprout anything, the seed that was watered with 50 ml daily yielded 12 sprouts while the seed that was watered with 90 ml daily yielded 16 sprouts
When we consider the amount of water given the seed & the produce of the seed, it is safe to conclude that with increase in daily water, there is increase in the number of sprouts by the seed
<u />
<u>Hence, C. Seed C germinates more with more water is the correct answer </u>
Answer:
t = 1.084 s
s = 8.25 m
Explanation:
given,
height from where skate board start (h) = 1 m
speed = 7.6 m/s
we know
v² = u² + 2 g h
v² =7.6² + 2×9.81× 1
v = 8.79 m/s
t = 1.084 s
then horizontal distance
s = 8.25 m
Answer:
a
b
Explanation:
From the question we are told that
The speed of the airplane is 
The angle is 
The altitude of the plane is 
Generally the y-component of the airplanes velocity is
=> 
=> 
Generally the displacement traveled by the package in the vertical direction is
=> 
Here the negative sign for the distance show that the direction is along the negative y-axis
=> 
Solving this using quadratic formula we obtain that
Generally the x-component of the velocity is
=> 
=> 
Generally the distance travel in the horizontal direction is
=> 
=>
Generally the angle of the velocity vector relative to the ground is mathematically represented as
![\beta = tan ^{-1}[\frac{v_y}{v_x } ]](https://tex.z-dn.net/?f=%5Cbeta%20%20%3D%20%20tan%20%5E%7B-1%7D%5B%5Cfrac%7Bv_y%7D%7Bv_x%20%7D%20%5D)
Here 
is the final velocity of the package along the vertical axis and this is mathematically represented as
=> 
=> 
and v_x is the final velocity of the package which is equivalent to the initial velocity 
So
![\beta = tan ^{-1}[-130.05}{57.96 } ]](https://tex.z-dn.net/?f=%5Cbeta%20%20%3D%20%20tan%20%5E%7B-1%7D%5B-130.05%7D%7B57.96%20%7D%20%5D)
The negative direction show that it is moving towards the south east direction
Answer:
The electromagnetic wave that travels the fastest through space is gamma ray
Explanation:
Electromagnetic wave is a type of wave which does not require material medium for its propagation. Examples of electromagnetic waves according to increasing frequency of the waves are gamma ray, x-ray, ultra violet ray, infra red, visible light, micro wave and radio waves.
Frequency of a wave is inversely proportional to period of oscillation of the wave. The higher the frequency of a wave, the shorter the period of oscillation. Gamma ray has the highest wave frequency in electromagnetic spectrum and shorter period of oscillation, thereby causing it to have the highest penetration power.
