find the kinetic energy of a ball of mass 200 grams moving at a speed of 20m/s
Answers
Kinetic Energy KE = ½ mv^2 where m is mass and v is velocity
Actually, v is a vector quantity, so KE = ½ mv•v
The dot product of 2 vectors a and b is abCosθ where θ is the angle between the vectors.
Obviously v•v = v^2 Cos0 = v^2
In this case, we have KE = ½ (0.2)(20^2) = 40kg-m^2/s^2 = 40J
So we have kinetic energy in the amount of 40 Joules.
Answer is 40J...............

Outline THREE adaptations of terrestrial plants for their survival in their habitat.
Answers
Answer:
Stomata for gas exchange, water resistant waxy cuticles on leaves and specialized cells for support.
Explanation:
Plants have undergone several modifications for life on land. These include the development of several mechanisms:
a waxy, thick water-repellent cuticle- the thick cuticle provides a barrier to water loss from plant tissues in the leaf. stomata- these moderate the evaporation of water, an important commodity to land dwelling terrestrial organisms. They also regulate gas change cells to provide strength and rigidity- plant cells are specialized cells that contain lignin and cellulose, these are rigid provide good support against gravitational forces, Without them the stem would break and the cells would readily lose waterMatch each research method with its corresponding example.

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
diameter of 10 cm in the box. Susan puts 1,000 1-cm glass marbles in her box.
1. Whose box has more empty space? Explain.
Answers
Answer:
Both boxes have the same amount of empty space
Explanation:
Given
Cube Box
[tex]Length = 10cm[/tex]
Robert:
1 glass marble
[tex]Diameter = 10cm[/tex]
Susan:
1000 glass marble
[tex]Diameter = 1cm[/tex]
Required
Whose box has more empty space?
First, we need to calculate the volume of the cubic box.
[tex]Volume = Length^3[/tex]
Substitute 10cm for Length
[tex]Volume = 10^3[/tex]
[tex]Volume = 1000cm^3[/tex]
Next, calculate the volume of Robert's glass
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 10cm[/tex] --- Given
Substitute 10 for diameter
[tex]r = \frac{1}{2} * 10cm[/tex]
[tex]r = 5cm[/tex]
So:
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 125[/tex]
[tex]Volume = 523.8cm^3[/tex]
Next, we determine the volume of Susan's 1000 glasses
Volume is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere
Where
r = radius
[tex]r = \frac{1}{2} * Diameter[/tex]
[tex]Diameter = 1cm[/tex] --- Given
Substitute 1cm for diameter
[tex]r = \frac{1}{2} * 1cm[/tex]
[tex]r = 0.5cm[/tex]
Substitute 0.5cm for radius in [tex]Volume = \frac{4}{3}\pi r^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3[/tex]
[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.125[/tex]
[tex]Volume = 0.5238[/tex]
But there are 1000 glasses.
So, the volume of 1000 glasses is:
[tex]Volume = 0.5238 * 1000[/tex]
[tex]Volume = 523.8cm^3[/tex]
--------------------------------------------------------------------------------------------------------------
For Robert:
[tex]Volume = 523.8cm^3[/tex]
For Susan:
[tex]Volume = 523.8cm^3[/tex]
Since, they have the same volume.
Both boxes have the same amount of empty space
From the dimensions of glass marble for robert and susan, we can say that; none of the given boxes have more empty space.
We are told that the cubic boxes have a measure of 10 cm for its' sides.
Formula for volume of a cube is;
V = lwh
where;
l is length
w is width
h is height
Thus; V = 10 × 10 × 10
V = 1000 cm³
For Robert;
We are told that he puts a glass marble with a diameter of 10 cm in the box. The glass is usually spherical in shape and the volume of a sphere is;
V = ⁴/₃πr³
Thus;
V_rob = ⁴/₃π × (10/2)³
V_rob = 523.6 cm³
Volume left for rob = 1000 - 523.6
Volume of empty space left for rob = 476.4 cm³
For Susan;
V = ⁴/₃πr³
Thus;
V_sus = ⁴/₃π × (1/2)³ × 1000
V_sus = 523.6 cm³
Volume left for susan = 1000 - 523.6
Volume of empty space left for susan = 476.4 cm³

b

c

d

Answers
Answer:
c
Explanation:
if the scientist was to look close there skin would be tightened up on the frog it is hard to see but if you look close you could see it
Answer:
C or D I think
Explanation:
D, you could compare frogs with no UV ray exposure to the ones with UV ray exposure
C, you can do the same but reverse
Edit: Meaning of control group is "A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results."
So its more likely to be D
