7. Can the speed of a particle be negative? Can the
velocity of a particle be negative? Give arguments to
support your answers.
Answer:
Suppose at time t1 = zero and v1 = 50 MPH
time t2 = 10 sec and v2 = 10 MPH
Change in speed = (v2 - v1) / (t2 - t1) = (10 - 50) MPH / (10 - 0) sec
Change in speed = -40 MPH / 10 sec = - 4 MPH / sec
If you specify the velocity as always East then
change in velocity = - 4 MPH East
Had the particle finished by moving in the Westerly direction then
Change in velocity = (-10 - 50) MPH / 10 sec = -60 / 10 MPH = -60 MPH East
Where West was the positive direction
Initially v1 was 50 East and v2 was -10 East with a difference of 60 MPH

Which nucleus completes the following equation?
Answer:
Option D. ⁸⁵₃₆Kr
Explanation:
⁸⁵₃₅Br —> ⁰₋₁e + ?
Let ⁿₘZ represent the unknown.
Thus, the equation becomes:
⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ
Next, we shall determine n, m and Z as follow:
85 = 0 + n
85 = n
Thus,
n = 85
35 = –1 + m
Collect like terms
35 + 1 = m
36 = m
Thus,
m = 36
ⁿₘZ => ⁸⁵₃₆Z = > ⁸⁵₃₆Kr
Thus, the equation:
⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ
Becomes:
⁸⁵₃₅Br —> ⁰₋₁e + ⁸⁵₃₆Kr
A certain AM radio wave has a frequency of 1.12 x 106 Hz. Given that radio waves travel at 2.99 x 108 m/s, what is the wavelength of this radio wave? (Round your answer to three significant figures.) Answer in "m" units
Answer:
2.67×10² m
Explanation:
Applying
V = λf............... Equation 1
Where V = Velocity of radio wave, λ = wave length, f = frequency.
make λ the subject of the equation
λ = V/f................ Equation 2
From the question,
Given: V = 2.99×10⁸ m/s, f = 1.12×10⁶ Hz.
Substitute these values into equation 2
λ = (2.99×10⁸)/(1.12×10⁶)
λ = 2.66696×10² m
λ ≈ 2.67×10² m

a rock of mass of 540 g in the air is found to have an apparent mass of 342 g when submerged in water (a) calculate the weight of the Rock given that the acceleration of the air g 10 m / s² to ignore the air resistance
Answer: 5.4 N
Explanation:
Given
mass of rock in the air is 540 g
Apparent mass of 342 gm when submerged in water
Weight of the rock is the product of mass and accleration due to gravity
[tex]\Rightarrow W=mg\\\Rightarrow 0.540\times 10=5.4\ N[/tex]

Which of the following scientists won a Nobel Prize for pioneering work in the
study of fiber optics?
O A. Marie Sklodowska-Curie
B. Warren Washington
O C. Charles Kuen Kao
D. Subrahmanyan Chandrasekhar
Scientists who won a Nobel Prize for pioneering work in the study of fiber optics is Charles Kuen Kao. Hence, option C is correct.
What is fiber optics ?Fiber optics is the study of technologies that transmit information as light pulses along a plastic or glass fiber. Thin glass fibers or filaments have been used to view inside the body since the 1930s, but they have long been deemed unsuitable for transmitting information over long distances because too much light is wasted in the process.
Charles Kao offered a solution in the 1960s: highly pure glass fibers could convey enough light. His invention has made optical fiber telecommunication practicable when combined with laser technology.
Charles Kao won the Nobel price in physics in 2009 for the groundbreaking achievements concerning the transmission of light in fibers for optical communication.

What can Lisa do to increase the strength of the electromagnet? She can use a nail with weaker magnetic properties. She can change the direction of the nail. She can increase the number of wire loops. She can reduce the current in the wire.
Answer:She can increase the number of wire loops
Explanation: When the number of loops of wire ( usually around the iron ) increases, the strength of the electromagnet is increased.
According to the equation
B=μ₀ N I
Where
μ₀ = permeability of the core
N= Number of turns of the coil
I= Current flowing through the coil
From the equation above , we can see that The strength of an electromagnet depends the amount of current, no of turns of coil and the permeability core of coil. we can now say that Increasing the number of wire loops increases the strength of electromagnet.
Therefore, Lisa should increase the number of wire loops to increase the strength of the electromagnet

Question 16 options:

F on the other side as object
non-existent
at infinity
Answer:
At infinity the image is formed
When a lens produces light rays that are parallel, the image is: C. non-existent.
A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.
Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.
Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.
On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.
In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.
