Answer:

B) change direction

Explanation:

Diffraction is the change of direction of waves that occurs when waves travel from one medium to another.

Reflection is the change of direction of waves when they bounce off of a barrier.

Refraction is the change of direction of waves that happens when waves pass from one medium to another.

Each of these are all the change in direction of waves.

Answer:

C. Data is analyzed on a computer

Explanation:

Computers can analyze electrical signals, not radio signals. This means that the radio waves need to be converted to electrical signals to help the computer analyze the data.

Explanation:

initial velocity=0

final velocity=40m/s

time=50s

acceleration=?

now,

a=v-u/t

a=40-0/50

a=40/50

a=0.8m/s^2

answer

Answer:

Time = 6 years

Explanation:

First, we will calculate the no. of half life periods required to reduce the mass of Protactinium to the given value:

[tex]m' = \frac{m}{2^{n} } \\\\2^n = \frac{m}{m'}[/tex]

where,

n = no. of half-life periods = ?

m = initial mass = 86.3 g

m' = remaining mass = 10.8 g

Therefore,

[tex]2^n = \frac{86.3\ g}{10.8\ g}\\\\2^n = 8\\2^n = 2^3[/tex]

Since the bases are the same. Therefore equating powers:

n = 3

Now we calculate the time:

[tex]Time = (n)(Half-Life)\\Time =(3)(2\ years)[/tex]

Time = 6 years

Answer: The correct answer is A). Animal burrow because burrow fossils represent the preserved byproducts of behavior rather than physical remains, they are considered a kind of trace fossil. One common kind of burrow fossil is known as Skolithos, and the similar Trypanites, Ophiomorpha and Diplocraterion.

Animal burrow is  an example of a trace fossil.

The preserved remnants of plants and animals that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that is typically older than 10,000 years is considered a fossil.

After death, soft body parts degrade quickly, while hard body parts, including bones, shells, and teeth, can be replaced by minerals that solidify into rock. Soft components like feathers, ferns, or other signs of life, such footprints or faeces, may also be preserved in extremely rare circumstances. Both less familiar fossils like ammonites and trilobites as well as microscopic-sized ones like single-celled foraminifera or pollen grains can be found in the remains.

A trace fossil, also known as an ichnofossil, is a record of biological activity preserved in the fossil record but without the actual preserved plant or animal remains. Contrasting with body fossils, which are the preserved remains of portions of an organism's body that were typically modified by later chemical activity or mineralization, are trace fossils. Ichnology, the study of such trace fossils, is the field of study of iconologists.

charge of electron, q = 1.602 x 10⁻¹⁹ C

The magnitude of the force required to move the electron through the given field is calculated as follows;

F = Eq

F = (1.375  x 10¹⁹ N/C) (1.602 x 10⁻¹⁹ C)

F = 2.203 N

Therefore, the magnitude of the force required to move the electron through the given field is 2.203 N

The focal length of the lens is approximately 115.3 cm. The explaination is  explained below.

To find the focal length of the lens, we can use the lens formula:

1/f = 1/v - 1/u

Where:

f is the focal length of the lens

v is the distance of the image from the lens

u is the distance of the object from the lens

Given:

v = 38.5 cm

u = 57.8 cm

Let's substitute these values into the formula:

1/f = 1/38.5 - 1/57.8

Now, let's calculate the right side of the equation:

1/f = (57.8 - 38.5) / (38.5 * 57.8)

= 19.3 / (2223.3)

≈ 0.008677

Now, we can find the focal length (f) by taking the reciprocal of both sides:

f = 1 / (0.008677)

≈ 115.3 cm

Therefore, the focal length of the lens is approximately 115.3 cm.

Answer: It is b

Explanation:

The lack of protein in the body will result in a lack of energy in the body. Hence, option B is correct.

Proteins are created from a variety of amino acid building blocks. Our body needs dietary protein to supply amino acids for the growth and upkeep of our cells and tissues. As we become older, our dietary needs for protein change.

Proteins are made up of many different amino acids that are joined together. Both plants and animals have a lot of these 20 different amino acid building blocks. Each protein has a unique ratio and arrangement of the 300 or more amino acids that make up a typical protein.

Our body is made up of thousands of different proteins, each of which has a specific function. They contribute to the structural components of our cells and tissues, along with the countless enzymes, hormones, and active proteins produced by immune cells.

Swampy areas are a transition area formed where water and dry lands tend to meet. Swampy areas are actually forested areas with contains moist and humid weather conditions which has necessitated the wet soil around such an environment.

Florida is a very typical example of a weather that supports the creation of swampy areas due to its humid, heavy rains, water spouts,turnadoes etc and other extreme weather conditions.

Answer:

v = 6.72 m/s

Explanation:

Given that,

Vertical height, h = 2.31 m

We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,

[tex]\dfrac{1}{2}mv^2=mgh\\\\v=\sqrt{2gh}[/tex]

Put all the values,

[tex]v=\sqrt{2\times 9.8\times 2.31} \\\\v=6.72\ m/s[/tex]

So, her speed at the bottom of the slide is equal to 6.72 m/s.

Answer:

(1) 2 ohms

(2) 12 Volts Across each resistor

(3) I₁ = 3 A, I₂ = 2 A, I₃ = 1 A

Explanation:

From the question,

(1) Equilvalent Resistance (Rt) for parallel connection is

1/Rt =(1/R₁)+ (1/R₂) + (1/R₃)

Where R₁ = 4 ohms, R₂ = 6 ohms, R₃ = 12 ohms

1/Rt = 1/4 +1/6 +1/12

1/Rt = (3+2+1)/12

1/Rt = 6/12

1/Rt = 1/2

Rt = 2 ohms.

(2) Since the resistors are connected in parallel, They will have the same potential difference across them,

Hence the P.d across each resistor = 12 Volts.

(3) For R₁,

I₁ = V/R₁ = 12/4

I₁ = 3 A.

For R₂,

I₂ = V/R₂

I₂ = 12/6

I₂ = 2 A

For R₃,

I₃ = V/R₃

I₃ = 12/12

I₃ = 1 A

Split F₁ into its horizontal and vertical components:

F₁ = F₁ cos(θ) i + F₁ sin(θ) j

(boldface = vector; regular font = magnitude)

By Newton's second law, if the object is in equilibrium, then

• the net horizontal force on the block is

∑ F = F₁ cos(θ) - F₃ = 0   →   F₁ cos(θ) = 70 N

• the net vertical force is

∑ F = F₁ sin(θ) + F₂ - W = 0   →   F₁ sin(θ) = 65 N

Recall that cos²(θ) + sin²(θ) = 1 for any θ, so we have

(F₁ cos(θ))² + (F₁ sin(θ))² = (70 N)² + (65 N)²

F₁² = 9125 N²

F₁ = √(9125 N²) ≈ 95.5 N

Answer: When air passes both above and below the airfoil, the air on top moves faster because of the curve, causing it to have a lower air pressure.

What is Momentum ?

Momentum is a concept in physics that describes an object's tendency to continue moving in its current direction at a constant speed. It is a vector quantity, meaning it has both magnitude and direction. The momentum of an object is defined as the product of its mass and velocity, and is represented by the equation: p = mv, where p is momentum, m is mass, and v is velocity.

In simple terms, momentum can be thought of as the "motion" of an object, and the larger the mass and velocity of an object, the greater its momentum. Momentum is a conserved quantity, which means that the total momentum of a system remains constant unless acted upon by an external force.

Given , Mass = 1000kg

Speed = 20 m/s

momentum = mv = 20000 kg m /s
