The equation of a line is commonly represented as y = mx + b, where y is the dependent variable (usually representing the vertical axis), x is the independent variable (usually representing the horizontal axis), m is the slope of the line, and b is the y-intercept.
The slope (m) of a line determines its steepness or inclination. It represents the rate of change of the dependent variable (y) with respect to the independent variable (x). A positive slope indicates an upward trend, while a negative slope indicates a downward trend.
The y-intercept (b) is the point where the line intersects the y-axis. It represents the value of y when x is equal to zero. It gives us a starting point on the y-axis for the line.
By knowing the slope and y-intercept, we can substitute their values into the equation y = mx + b to obtain the specific equation of the line that satisfies the given conditions. This equation allows us to determine the value of y for any given value of x along the line.

1- A positive charge of 3x10-7 is located in a field of 27N/C directed toward the south. What is the force acting on the charge?
2- A positive test charge of 5x10-6Cis in an electric field that exerts a force of 2x10-4N on it.
What is the magnitude of the electric field at the location of the test charge?
Explanation:
(1) Given that,
A charge, [tex]q=3\times 10^{-7}\ C[/tex]
Electric field, E = 27 N/C
We need to find the force acting on the charge. The force on the charge is given by :
[tex]F=qE\\\\F=3\times 10^{-7}\times 27\\F=8.1\times 10^{-6}\ N[/tex]
So, the force acting on the charge is [tex]8.1\times 10^{-6}\ N[/tex]
(b) Charge, [tex]q=5\times 10^{-6}\ C[/tex]
Force, [tex]F=2\times 10^{-4}\ N[/tex]
Let E be the electric field.
[tex]E=\dfrac{F}{q}\\\\E=\dfrac{2\times 10^{-4}}{5\times 10^{-6}}\\\\E=40\ N/C[/tex]
So, the electric field is 40 N/C.

A scientist wants to study the movement of air in a hurricane in order to help prevent damage. Which tool should the scientist use to find out more about the movement of air?(1 point)
a computer model
a barometer
a levee
a Doppler radar
Answer:
B
Explanation:
IM PRETTY SURE it is B
The scientist should use a barometer to learn more about the movement of air. A barometer is a scientific instrument that measures the pressure of air in a particular environment.
What a barometer is used for?A barometer is a scientific instrument that measures the pressure of air in a particular environment. Short-term weather changes can be predicted by the pressure tendency. In surface weather analysis, many air pressure measurements are used to help locate surface troughs, pressure systems, and frontal boundaries.Furthermore, just as air flows out of the high-pressure environment inside an inflated balloon if the opening is not tied, air in the atmosphere will move to a lower pressure area, resulting in wind. An anemometer is a device that measures the speed of the wind. The readings on each of these digital barometers are slightly different! Layers of air wrap around the Earth to form the atmosphere.To learn more about Barometers, refer to:

A ball is thrown horizontally from the roof of a building 50. m tall and lands
45 m from the base. What was the ball's initial speed?
Answer:7.92 m/s
Explanation:
A ball is thrown horizontally from the roof of a building 50. m tall and lands 45 m from the base then the ball's initial speed is 14.10 m/s
What is speed?The rate of change of position of an object in any direction is called speed. Speed is scalar quantity.
speed = distance/time
s=d/t
Where,
s is the speed in m/sec
d is the distance travaled in m
t is the time taken in sec
Given that in the question ball travel a height from building of 50 m to a distance 45 m from the base so total distance travelled is given as 45 m.
Body is travelling downward under the influence of gravity.
Using equation of motion under gravity,
y = ut + ½gt² , where u = 0 m/s in y direction and
y = ½gt²
t² = 2y / g
t² = 2*50/9.8
t = 3.19 sec
ball's initial speed in x direction is given as
u = 45/3.19
u= 14.10 m/sec.
The balls initial speed is given as 14.10 m/sec.

If the voltage of a circuit is 6V, and the power is 4W, what is its resistance?
Answer:
9 ohms
Explanation:
P = V²/R
R = v²/p = 6²/4 = 36/4 = 9 ohms.
The resistance is 9 Ohm.
To find the resistance, we need to know about the power in term of resistance and voltage.
What is the value of power in terms of resistance and voltage?We know that power=work/timeElectrostatics work is given as voltage ×charge. So, power=(Voltage×charge)/timeAgain, charge/time is given as current. So, power = Voltage×currentFrom Ohm's law, we know that current=voltage/resistance. So, power= voltage ²/resistance. What is the resistance, if power is 4W and voltage is 6V?Resistance in term of power and voltage is given as Resistance= voltage ²/powerSo, resistance=6²/4=36/4= 9 OhmThus, we can conclude that the resistance is 9 Ohm.

gravitational acceleration = [tex]\frac{G * m}{r^{2} }[/tex]
G is the gravitational constant = G = 6.673×10^-11 N m^2 kg^-2
after substitution :
6.673×10^-11 * 3.2x10^23 / (2.43x10^6)^2

Which action is an example of a force that operates at a distance.
A. A baseball thrown by a player.
B. A pebble falling to the ground
C. Fish swimming in the water
D. A sailboat sailing on a lake
An action which is an example of a force which operates at a distance is a pebble falling to the ground. Thus, the correct option is B.
What is force?A force is an influence which can be changed upon with the motion of an object. A force can cause an object with some amount of mass to change the velocity of the object, i.e., to accelerate the object. Force can also be described as a push or a pull of the object. A force is a vector quantity because it has both the magnitude and direction.
A pebble falling to the ground level is an example of the force which operates at a specific distance. A force applied on the pebble covers some distance.

Use Newton’s First Law of Motion and the concept of inertia to explain what happens to a person in a head-on car accident who is not wearing a seat belt. How does wearing a seat belt help?
Answer:
Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
Explanation:
According to Newtons first law of motion, a passenger tends to continue in the state of uniform motion even after the accident which causes the passenger to move forward.
According to the Newtons first law of motion, an object will continue in a state of rest or uniform motion unless it is acted upon by an external force. This is also known as the law of inertia.
While in a car undergoing uniform motion and suddenly the car is involved in an accident which causes the vehicle stop abruptly, a person suddenly moves forward because of the tendency to continue in the former state of uniform motion according to Newtons first law.
A seat belt helps to prevent the person from suddenly moving forward in a way that may lead to injury as a result of the accident.
