Two technicians are discussing electromagnetic induction. Technician A says that the induced voltage can be increased if the speed is increased between the conductor and the magnetic lines of force. Technician B says that the induced voltage can be increased by increasing the strength of the magnetic field. Which technician is correct?
Answer:
Both technicians are correct
Explanation:
In electromagnetic induction, the induced voltage can be increased by increasing the relative speed between the conductor and the magnetic line of force, by increasing the strength of the magnetic field, which increases the magnetic lines of force, Increase the strength of the magnetic field, so there are more flux lines, and also by increasing the angle between the flux lines and the conductor to a maximum of 90 degrees.

1) While traveling along a highway a driver speeds up from 10 m/s to 26 m/s in 4 seconds. What is the automobile's acceleration? *
Answer:
4m/s^2
Explanation:
using the formula a = (v_f - v_i) / Δt we can use final velocity, initial velocity, and accel. time to calculate the accel. rate
In this problem it would be a=(26m/s - 10m/s) / 4s
our answer would be 4m/s^2

A car rolls down a ramp in a parking garage. The horizontal position of the car in meters over time is shown below. Graph of horizontal position x (in meters) on y axis and time (in seconds) on x axis. The initial position is -3 m at t=0 s, and the position increases linearly to 3 m at t=8 s. Then the position is constant at 3 m until t=16 s, then increases linearly to 9 m at t=24 s.
Answer:
Explanation:
At t = 0 , X = -3 m
At t = 8s , X = + 3 m .
At t = 16s , X = + 3 m
At t = 24 s , X = + 9 m
Graph is shown in the attached file .
The displacement of the car between 8 seconds and 24 seconds is 6 m.
The given parameters:
Initial position of the car, x₁ = -3 m, time = 0 sSecond displacement, x₂ = 3 m, time = 8.0 sThird displacement, x₃ = 3 m, time = 16 sFinal displacement, x₄ = 9 m, time = 24 sThe displacement of the car between 8 seconds and 24 seconds is calculated as follows;
the position of the car at 8 seconds = 3 m
the position of the car at 24 seconds = 9 m
The displacement of the car = 9m - 3m = 6 m
Thus, the displacement of the car between 8 seconds and 24 seconds is 6 m.

The answer is A)0.20 but can someone explain how to solve it plsss?!!
Explanation:
The velocity of the wave is:
v = (9.0π rad/s) / (0.1π / cm)
v = 90 cm/s
v = 0.9 m/s
Velocity of a standing wave on a stretched string is:
v = √(T / (m/L))
0.9 m/s = √(0.081 N / (M / 2.0 m))
0.81 m²/s² = 0.081 N / (M / 2.0 m)
M / 2.0 m = 0.1 kg/m
M = 0.2 kg
You are riding in a spaceship that has no windows, radios, or other means for you to observe or measure what is outside. You wish to determine if the ship is stopped or moving at constant velocity. What should you do
Answer: give up because nothing can be done.
Explanation:
You would have to give up because you have taken on an impossible task. And nothing can be done because there is no known means available to you to measure or observe what is happening outside the spaceship. And as a result this has made it an impossible task knowing the velocity of the ship or finding out.

The volume of air is 53.28 m 3 . Convert it into scientific notation. 5.328×101 m3 532.8×101 m3 0.5328×103 m3 Both A and C
Explanation:
It is given that, the volume of air is 53.28 m³. We need to convert it into scientific notation.
Any number in scientific notation can be given by :
[tex]N=a\times 10^b[/tex]
a is real no and b is any integer
We have, V = 53.28 m³
To write it into scientific notation, shift decimal before 3 such that,
[tex]V=\dfrac{5328}{100}[/tex]
No multiply and divide by 10. So,
[tex]V=\dfrac{5328}{100}\times \dfrac{10}{10}\\\\V=\dfrac{5328}{1000}\times 10\\\\V=5.328\times 10^1\ m^3[/tex]

A girl hits a baseball with a bat. When the bat strikes the ball, what is the
reaction force?
A. Earth's gravity pulls the ball down.
B. The ball accelerates upward.
C. The bat pushes against the girl's hands.
D. The ball pushes against the bat.
When the bat strikes the ball, the ball pushes against the bat due to reaction force, The correct option is D.
What is reaction force?It is a type of force that acts in the opposite direction of the applied force, for example when one applies active force towards the stationery wall, the wall exerts a reactive force in the opposite direction.
Therefore when a girl hits a baseball with a bat, the baseball applies an active force on the ball in which as a result of reactive force the ball pushes against the bat.

Explain what radiation is in 1-2 paragraphs please, thank you
Answer:
Explanation:
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.

Does temperature affect the amount of sugar that dissolved in tea? Why
Answer:
Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement. For example, if you add the same amount of sugar to a cup of hot tea and a cup of iced tea, the sugar will dissolve faster in the hot tea.
Please help!!! The radius of a circle is 5.5 cm, the circumference in meters is 34.56, the area in square meters is 95.03. What is the area under the curve at the right?
Answer:
47.515 cm²
In meter square= 4.7515 *10^-3 m²
Explanation:
The radius of a circle = 5.5 cm
In meter= 5.5*0.01
= 0.055 m
the circumference= 34.56 cm
in meters = 34.56 cm*0.01
= 0.3456 meters
the area= 95.03 cm²
in square meters =95.03*(0.01)²
in square meters= 9.503*10^-3 m²
. area under the curve at the right
= Area of semi circle
= Area of circle/2
= 95.03 /2

What is true of daylight hours at locations north and south of the equator? Days are longer than nights north of the equator. Nights are longer than days south of the equator. The length of days and nights change with the seasons.
Answer:
The length of days and nights change with the seasons.
Explanation:
Distance from the equator along with the tilt of Earth's rotational axis contributes to day and night period differences. Daylight hours or the period of sunlight exposure vary due to the inclined axis of the latitudes. In the northern hemisphere during summers, the tilt of the axis is towards the sun which brought more sunlight to the exposed region. And therefore the length of day hours is more than the southern hemisphere which at the same time will be tilted away from the sun.
