Question 1 (1 point)
A boy on a treasure hunt walks 12 paces West, then 21 paces North, then 25 paces
East. What is the magnitude of boy's resultant displacement in meters?
Answer:
The magnitude of the boy's displacement is 24.698 paces which is in the direction of approximately 58.24° North of East
Explanation:
The given parameters are;
The distance West the boy on a treasure hunt walks = 12 paces
The distance North the boy on a treasure hunt then walks = 21 paces
The distance East the boy on a treasure hunt then walks = 25 paces
Writing the displacement in vector format, gives;
d = -12·i + 21·j + 25·i
Which gives
d = 13·i + 21·j
The magnitude of the boy's resultant displacement is given as follows;
[tex]\left | \mathbf{d} \right | = \sqrt{d_x^2 + d_y^2}[/tex]
Where;
[tex]d_x = 13, \ d_y = 21[/tex]
[tex]\left | \mathbf{d} \right | = \sqrt{13^2 + 21^2} = \sqrt{610} \approx 24.698 \ paces[/tex]
The magnitude of the boy's displacement is 24.698 paces
The direction of the displacement is tan⁻¹(21/13) ≈ 58.24° North of East.
a flashlight bulb with a potential difference of 6.0 v across it has a resistance of 8.0 how much current is the bulb filament
Answer:
I = 0.75 Amp
Explanation:
Ohm's Law
Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points. The constant of proportionality is called the Resistance (R) of the conductor.
The formula can be expressed as:
V = I.R
The intensity of the current through a resistor can be calculated by solving the equation for I:
[tex]\displaystyle I=\frac{V}{R}[/tex]
A flashlight bulb is an example of a resistor with the specific task to emit light when it's hot enough.
The potential difference (or voltage) is V=6 V and the resistance is R=8Ω, thus the current is:
[tex]\displaystyle I=\frac{6~V}{8~\Omega}[/tex]
I = 0.75 Amp

Explain why clear-cutting is a more destructive method of wood harvesting than selective cutting.
Answer:
Clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals.
Explanation:
edge 2022
A forestry/logging practice known as clear-cutting, clear felling, or clear-cut logging involves consistently cutting down the majority or all of the trees in a given region. Foresters utilize it to cultivate particular types of forest ecosystems and to advance particular species, in addition to harvesting shelter wood and seed trees.
What is deforestation?The removal of a forest or tree stands from land before it is used for a purpose other than as a forest is known as deforestation or clearing of forests. The use of forest land for urban, agricultural, or ranch purposes is referred to as deforestation. In tropical rainforests, there is the greatest concentration of deforestation. Forests currently cover about 31% of the Earth's land area. With half of that loss occurring in the previous century, this is a third less forest cover than there had before agriculture's growth.
As a result of clear-cutting, no trees are left to protect the topsoil or serve as a haven for wildlife. In turn, this causes soil erosion and soil fertility to be destroyed, as well as the removal of the trees required to produce seeds for natural forest development to continue. Animal populations are also pushed out of their natural habitats by clear-cutting, forcing them to look for new homes.

Answer:
1. Net force = 90 N
2. Acceleration = 9 m/s²
Explanation:
From the question given above, the following data were obtained:
Mass (m) of bag = 10 Kg
Force applied 1 (Fₐ₁) = 45 N
Force applied 2 (Fₐ₂) = 60 N
Force of friction (Fբ) = 15 N
Net force (Fₙ) =?
Acceleration (a) =?
1. Determination of the net force acting on the bag.
We'll begin by calculating the total force applied on the bag.
Force applied 1 (Fₐ₁) = 45 N
Force applied 2 (Fₐ₂) = 60 N
Total force applied = Fₐ₁ + Fₐ₂
Total force applied = 45 + 60
Total force applied = 105 N
Finally, we shall determine the net force acting on the bag. This is illustrated below:
Total force applied = 105 N
Force of friction (Fբ) = 15 N
Net force (Fₙ) =?
Net force (Fₙ) = Total force applied – Force of friction (Fբ)
Net force (Fₙ) = 105 – 15
Net force (Fₙ) = 90 N to the right
2. Determination of the acceleration of the bag.
Mass (m) of bag = 10 Kg
Net force (Fₙ) = 90 N
Acceleration (a) =?
Force (F) = mass (m) × acceleration (a)
90 = 10 × a
Divide both side by 10
a = 90 / 10
a = 9 m/s²
Thus, the acceleration of the bag is 9 m/s² to the right.

SEXUAL REPRODUCTION:
Sexual reproduction is a type of reproduction that involves two organisms (a male and a female). The male organism produces a gamete called SPERM while the female organism produces a gamete called EGG. The gametes are produced via a process called MEIOSIS. Meiosis is a process of cell division whereby genetically different daughter cells are produced. The genetic variation is attributed to a process called crossing over, which is the exchange of genetic material between non-sister chromatids of homologous chromosomes. At the end of the fertilization process between male sperm and female egg, the genetic material of the offspring will contain genes from both parents in unique combinations.Learn more at: https://brainly.com/question/11622266?referrer=searchResults

Explanation: Mass is eliminated when equating elastic potential energy with kinetic energy.
Mass is eliminated when equating gravitational potential energy with kinetic energy. Therefore option D is correct.
What is gravitational potential energy?The energy that an item has or acquires when its location changes as a result of being in a gravitational field are known as gravitational potential energy. Gravitational potential energy can be defined as energy that has a connection to gravitational force or gravity.
The energy of gravity, or gravitational potential energy, is also related to the Earth. An object has gravitational potential energy if it is at a certain height above the Earth's surface. The object's potential energy is transformed into kinetic energy when it is released. Due to the rule of conservation of energy, the sum of the two is always constant.
The test object is positively pulled by the gravitational force from infinity to a location inside the gravitational field. Because gravitational force is inverse square, it is 0 at infinity. As a result, infinity is used as the starting point.

Melissa my pet cow from childhood that i could ride like a horse had a weight of 0.65 tons. Philip my pet rabbit had a weight of 192 ounces. How many philips would it take to weigh as much as one melissa
Answer:
11 times the weight of Philip.
Explanation:
From the question given above, the following data were obtained:
Weight of Melissa (i.e cow) = 0.65 tons
Weight of Philip (i.e rabbit) = 192 ounces
Next, we shall express the weight of Philip (i.e the rabbit) in tons. This can be obtained as follow:
1 ounce = 3.125×10¯⁵ ton
Therefore,
192 ounce = 192 ounce × 3.125×10¯⁵ ton / 1 ounce
192 ounce = 0.06 ton
Thus, the weight of Philip (i.e the rabbit) in ton is 0.06 ton.
Next, we shall determine the ratio of the weight of Melissa (i.e the cow) to the weight of Philip (i.e the rabbit). This can be obtained as follow:
Weight of Melissa (i.e cow) = 0.65 ton
Weight of Philip (i.e rabbit) = 0.06 ton
Melissa /Philip = 0.65/0.06
Melissa /Philip = 11
Melissa = 11 × Phillip
Thus, it will take 11 times the weight of Philip to weigh as much as Melissa.

A 4 kg jug of juice is pulled forward across a horizontal breakfast table, by a 12 N forward-directed force. A frictional force also impedes the jug's motion. What is the coefficient of kinetic friction between the table and jug, if the jug accelerates to the right at 2 m/s^2 ?
A 0.08
B 0.1
C 0.2
D 0.3
Answer:
0.1Explanation:
According to equation of motion;
\sum F = ma
m is the mass of the body
a is the acceleration
\sum F = Fm - Ff (along the horizontal)
Fm is the moving force
Ff is the frictional force
Given;
Fm = 12N
Ff = nR = nmg
Ff = n(4)(9.8)
Ff = 39.2n
Substitute the given value into the expression above;
Fm - Ff = ma
12 - 39.2n = 4(2)
-39.2n = 8-12
-39.2n = -4
n = 4/39.2
n = 0.1
Hence the coefficient of kinetic friction between the table and jug is 0.1
