What is it called when an unwanted material that contains radioactive atoms is present on another material?
Answer:
Radioactive contamination
Explanation:
radioactive contamination is when radioactive atoms are present on somethingWhen an unwanted material that contains radioactive atoms is present in another material is known as Radioactive contamination.
What are radioactive atoms?The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive. Alpha, beta, and gamma decay are three of the most prevalent forms of decay, and they all entail the emission of one or more particles.
According to the statement, "For a given time, the number of nuclei of the elements existing at that moment is exactly proportional to the rate of radioactive decay of an atom." This may be expressed as, where N is the total number of nuclei, d N d t N.
When radioactive particles are deposited on, inside of, or around an individual or a business, nuclear radiation results. When radioactive materials are discharged into the environment, they have the potential to contaminate the air, water, surfaces, soil, plants, buildings, people, and animals.

Learning Task No. 3:
Use the diagram showing the relationship among current,
resistance and voltage. Explain the relationship between
current and voltage;
voltage and resistance;
current and resistance.
Write your answer below
Answer:
There is no diagram in this question, however, the question can be answered based on general understanding.
1. current and voltage; direct relationship
2. current and resistance; inverse relationship
3. voltage and resistance; direct relationship
Explanation:
The relationship between current (I), resistance (R) and voltage (V) has been explained by Ohms in his law. In Ohms law, which states that the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.
This further means that if the voltage (V) increases, then the current (I) also increases and vice versa while if the resistance (R) is increased, the current (I) decreases and vice versa.
The equation represented by this law is:
V = IR or I = V/R or R = V/I
Likewise, the when the resistance is increased, the voltage increases and vice versa.
Therefore;
- Current (I) is directly proportional to the Voltage (V)
- Current (I) is inversely proportional to the Resistance (R)
- Voltage (V) is directly proportional to the Resistance (R)

Long-Distance Space Travel
Many scientists and engineers are working toward the goal of sending astronauts to Mars. The trip is estimated to take about 9 months each way. It is very expensive to take enough oxygen to last the whole trip. The astronauts also need enough food, and there has to be a way to get rid of excess carbon dioxide created by their cellular respiration.
Present a plan for the astronauts. Explain how growing food during space flight will help regulate carbon dioxide and oxygen levels. List the supplies the astronauts would need.
Answer:
Green house
Explanation:
You could build a little green house sorta thing bc plants produce oxygen and then the plants you can eat also you are supposed to have water so there s the plants water!
Air. Plants are necessary for the creation of breathable air on Earth. During photosynthesis, plants convert carbon dioxide into oxygen and improve the air we breathe.
What food during space flight help regulate carbon dioxide?They can serve as food or as a cooling environment for astronauts traveling in space. Plants can help regulate cabin humidity by metabolizing atmospheric carbon dioxide to produce useful oxygen.
The crews of human spacecraft may experience psychological benefits from growing plants in space. The ISS could benefit from plant growth by producing oxygen for astronauts to breathe and removing carbon dioxide from the atmosphere.
According to the researchers' findings in their article, eating these fresh foods is also thought to have the additional advantages of reducing stress and boosting morale.
Therefore, The ability to grow vegetables in greenhouses in space could help astronauts supplement their diets.

26.5m/s²
Explanation:
Given parameters:
Tangential velocity of the object = 23m/s
Radius of track = 20m
Unknown:
Acceleration = ?
Solution:
The acceleration of the body is its centripetal acceleration. It is given by;
a = [tex]\frac{v^{2} }{r}[/tex]
v is the tangential velocity
r is the
a = [tex]\frac{23^{2} }{20}[/tex] = 26.5m/s²
A projectile is launched with an initial velocity of (40 m/s), at an angle of (30°) above
horizontal. What is the maximum height (ymax) reached by the projectile?
(Use g=10 m/s2).
Answer:
330.5 m
Explanation:
In this case, the object is launched horizontally at 30° with an initial velocity of 40 m/s .
The maximum height will be calculated as;
[tex]h=\frac{v^2_isin^2\alpha }{2g}[/tex]
where ∝ is the angle of launch = 30°
vi= initial launch velocity = 40 m/s
g= 10 m/s²
h= 40²*sin²40° / 2*10
h={1600*0.4132 }/ 20
h= 661.1/2 = 330.5 m

A ball of mass of 0.5kg is dropped from a height of 2m.
Assuming that all of the GPE is transferred to KE, what
will be the velocity of the ball when it hits the ground?
Answer:
6.3m/s
Explanation:
Given parameters:
Mass of the ball = 0.5kg
Height = 2m
Unknown:
Velocity when the ball hits the ground = ?
Solution:
Since the potential energy is transformed into kinetic energy;
P.E = K.E
mgh = [tex]\frac{1}{2}[/tex] m v²
cancelling m;
gh = [tex]\frac{1}{2}[/tex] v²
v² = 2gh
v = √2gh
Insert the parameters and solve;
v = √2gh = √ 2 x 9.8 x 2 = 6.3m/s

A rubber ball thrown at a speed of 5 m/s hit a flat wall and
returned to the thrower at a speed of 5 m/s. Which
statement correctly describes the momentum of the rubber
ball?
Answer:
See the explanion below
Explanation:
Linear momentum is defined as the product of mass by velocity and can be calculated by the following equation.
[tex]P =m*v[/tex]
where:
P = momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
When the ball hits the wall it receives a force for a very short time, this time and force value is known as momentum and can be calculated by the following expression.
[tex]-(m_{1}*v_{1}) + (F*t)=(m_{1}*v_{2})[/tex]
where:
m₁ = mass of the ball [kg]
v₁ = 5 [m/s]
v₂ = 5 [m/s]
v₁ = v₂
[tex]F*t = Imp[/tex]
[tex]Imp = (m_{1}*v_{1})+ (m_{1}*v_{2})\\Imp = 2*m*v_{1}[/tex]
It can be said that the impulse is equal to 2 times the speed of throwing by the mass.

5. A pendulum is 0.25 m long. What is the frequency of its oscillations?
Answer:
I would say your answer is: The frequency of oscillations is 1 HZ { 1 cycle per second}.
The frequency of pendulum oscillations which is 0.25 m long is 1 HZ (1 cycle per second).
What is frequency?The quantity of waves leaving a spot in relation to time is known as its frequency. Hertz units are used to measure frequency. Humans with typical hearing abilities can hear frequencies between 20 Hz and 20 kHz. The frequency is defined mathematically as the time period divided by the factor of one. The number of rotations or vibrations that a body in periodic motion makes in a given amount of time.
A moving disturbance is referred to as a wave. The waves that must pass through a medium like air or water are referred to as mechanical waves. Other forms of waves, such as electromagnetic waves, can pass through both mediums and a vacuum.
Given:
The length of the pendulum, l = 0.25 m,
Calculate the frequency by following the formula:
f = [tex]1/T[/tex] =ω / 2[tex]\pi[/tex]
Therefore, the frequency of pendulum oscillations which is 0.25 m long is 1 HZ (1 cycle per second).
