Answer:

Radioactive contamination

Explanation:

When an unwanted material that contains radioactive atoms is present in another material is known as Radioactive contamination.

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.

Answer:

C. a cow skeleton in the dessert.

Explanation:

i had this question and this is how i thought it through. fossils are usually referred to as extinct animal remains. a cow is not a extinct animal and it doesn't live in the dessert so that would make it a false answer. another reason would be that the rest of the answers make sense. for answer a. it is a trace fossil, b. is a preserved fossil, d. is a petrified fossil. so that leaves c.

The volume of a sample of plasma change when the substance is moved from one container to another because plasma can have lots of space between its particles, so it naturally expands and compresses.

When sufficient energy has been supplied to the gas, the electrons of the gas have enough energy to escape from their atoms or molecules and the atoms then exist as ions.

Plasma contains ions and electrons that are free to.move around easily.

Matter in the plasma state do not have constant volume or shape, rather it has variable volume and shape. Plasma is the most common form of visible matter in the universe.

Examples of matter that exist in the plasma state include lightning, sparks, the sun, etc

Therefore, the volume of a sample of plasma change when the substance is moved from one container to another because plasma can have lots of space between its particles, so it naturally expands and compresses.

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).

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).

i hooked this up btw

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

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)

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.

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
