Answers
The electric field strength at a distance of 10 cm from a charge of 2 μC is 3.6 x 10⁵ N/C.
What is called electric field?If there's a charge present in any form, an electric field is linked with every point in space. The strength and direction of the electric field are expressed by the value of E, sometimes referred to as the strength of the electrical field, electric field intensity, or simply the electric field.
The following formula determines the magnitude of the electric field generated by a point charge:
where,
E = Electrical Field Strength = ?
k = 9 x 10⁹ Nm²/C²
q = magnitude of charge
q = 2 μC = 2x 10⁻⁶ C
r = distance = 10 cm
r = 0.10 m
Therefore,
When the values are entered into the equation, we obtain:
E = 9 x 10⁹ * (2 x 10⁻⁶) / (0.1)²
E = 3.6 x 10⁵ N/C

The drawings show three examples of the force with which someone pushes against a vertical wall. In each case the magnitude of the pushing force is the same. Rank the normal forces that the wall applies to the pusher in ascending order (smallest first).1st drawing is a medium angle2nd drawing is a small angle3rd drawing is a large angle (almost 90 degrees and perpendicular to the wall)
Answers
The normal forces that the wall applies to the pusher in ascending order are :Normal force in the third drawing (large angle),Normal force in the first drawing (medium angle),Normal force in the second drawing (small angle).
The normal force is the force that an object exerts on another object that is in contact with it. In the case of a person pushing against a wall, the normal force is the force that the wall applies to the person.
The magnitude of the normal force is determined by the angle at which the person is pushing against the wall. For a given magnitude of the pushing force, the normal force will be smaller when the angle is larger and larger when the angle is smaller.
In the first drawing, the angle is medium, so the normal force will be between the normal force in the second and third drawings.
In the second drawing, the angle is small, so the normal force will be larger than the normal force in the first drawing and smaller than the normal force in the third drawing.
In the third drawing, the angle is large, so the normal force will be the smallest of the three.

Experiment: Friction Investigation using a matchbox, pebbles, coins, string, small plastic bag, towel, small scale or balance
Answers
Below is an experiment investigating friction using a matchbox, pebbles, coins, string, small plastic bag, towel, small scale or balance.
Procedure:
Cut a piece of string that is long enough to wrap around the matchbox with some extra length to hold onto.Tie one end of the string to the matchbox.Put some pebbles or coins inside the small plastic bag.Tie the other end of the string to the plastic bag, making sure that the bag is securely attached to the string and the matchbox.Place the towel on a table or flat surface.Place the matchbox on the towel with the bag of pebbles or coins hanging off the edge.Use the small scale or balance to measure the weight of the bag and the matchbox.Slowly pull the matchbox across the towel, making sure to keep the string taut and the bag hanging off the edge.Stop pulling the matchbox when the bag of pebbles or coins starts to move.Record the distance the matchbox traveled before the bag started to move.Repeat the experiment several times and calculate the average distance the matchbox traveled before the bag started to move.Change one variable at a time (e.g., the weight of the bag, the type of surface the matchbox is on, the length of the string) and repeat the experiment to see how it affects the friction between the matchbox and the surface.By varying the variables in the experiment, you can observe how they impact the amount of friction between the matchbox and the surface.
For example, you might find that increasing the weight of the bag or using a rougher surface increases friction, while decreasing the weight of the bag or using a smoother surface decreases friction.
What is friction?Friction is a force that opposes motion between two surfaces that are in contact. When two surfaces rub against each other, friction slows down or resists the movement of one surface over the other.
Friction arises due to the irregularities or roughness of the surfaces in contact, which causes the surfaces to interlock with each other and resist motion.

A long, straight conveyor belt at a sushi restaurant carries sushi past customers with a constant velocity. If the sushi roll you want is 4.30 m to the right of you 11.0 s after exiting the little door at the beginning of the conveyor belt, and it is still 2.10 m to the right of you 10.0 s later, how far is the little door to the right of you?
Answers
distance = velocity × time
Let's assume that the velocity of the conveyor belt is v, and the distance between the little door and the sushi roll is d.
According to the information given, the sushi roll is 4.30 m to the right of you 11.0 s after exiting the little door. We can write this as:
4.30 m = v × 11.0 s
Similarly, the sushi roll is still 2.10 m to the right of you 10.0 s later:
2.10 m = v × 10.0 s
Now, we can solve these two equations simultaneously to find the velocity of the conveyor belt. Dividing the second equation by the first equation, we get:
2.10 m / 4.30 m = (v × 10.0 s) / (v × 11.0 s)
Simplifying, we find:
0.4884 ≈ 0.9091
Now, we can use either equation to find the value of v. Let's use the first equation:
4.30 m = v × 11.0 s
Dividing both sides by 11.0 s:
v ≈ 4.30 m / 11.0 s
v ≈ 0.3909 m/s
Now that we know the velocity of the conveyor belt, we can calculate the distance between the little door and you. Using the second equation:
2.10 m = v × 10.0 s
Substituting the value of v:
2.10 m = 0.3909 m/s × 10.0 s
2.10 m = 3.909 m
Therefore, the little door is approximately 3.909 meters to the right of you.
A hollow glass sphere has a density of 1.3g/cm at 20 C. Glycerine has a density of 1.26 g/cm at 20 C. At what temperature would the sphere begin to float in glycerine
Answers
A hollow glass sphere has a density of 1.3g/cm at 20 C. Glycerine has a density of 1.26 g/cm at 20 C.
To determine the temperature at which the hollow glass sphere begins to float in glycerine, we need to calculate the density of glycerine at various temperatures and compare it to the density of the glass sphere.
The density of glycerine changes with temperature, so we need to use a density-temperature chart or equation to determine the density of glycerine at different temperatures.
Assuming the hollow glass sphere has a uniform wall thickness, we can calculate its volume by subtracting the volume of the hollow interior from the volume of the whole sphere
Volume of sphere = (4/3)π\(r^{3}\)
Volume of hollow interior = (4/3)π\((r-t)^{3}\)
Volume of glass wall = (4/3)π(\(r^{3}\) - \((r-t)^{3}\)), where t is the thickness of the glass wall.
From the density and volume of the glass sphere, we can determine its mass
Mass of glass sphere = Density of glass sphere x Volume of glass sphere
Next, we can use Archimedes' principle to determine the volume of glycerine displaced by the glass sphere when it is submerged in the glycerine
Volume of glycerine displaced = Mass of glass sphere / Density of glycerine at the given temperature
When the glass sphere floats, the volume of glycerine displaced will be equal to the volume of the glass sphere. Thus, we can set the two volumes equal to each other and solve for the temperature at which the density of glycerine matches the density of the glass sphere
Volume of glass sphere = Volume of glycerine displaced
(4/3)π\(r^{3}\) - (4/3)π\((r-t)^{3}\) = Mass of glass sphere / Density of glycerine at the given temperature
Hence, for the temperature requires knowing the radius and thickness of the glass sphere and the mass of the sphere.

Explanation:
a) A drone flies 150 m to southwest (directly between south and west), then flies 85 m directly
south, and finally flies 550 m in the direction 35° north of east. Use the analytical method to
find the resultant displacement of the drone (magnitude and direction)
b) A motorcycle moving at 75 mph starts to slow down at a constant rate of 0.25 m/s2 for 15
seconds. Find its final velocity (in both m/s and mph) and the total distance (in meters) that
it traveled during this 15 s timeframe.
Answers
The magnitude of the resultant displacement of the drone is 476.6 m, and the direction is 46.7° north of east.
The final velocity of the motorcycle is 29.125 m/s (or 65.1 mph), and it traveled a total distance of 498.125 m during the 15 s timeframe.
How to solve for final velocityA. x = 550cos(35°) = 451.92 m
y = 550sin(35°) = 316.23 m
Now we can add the x components and y components separately:
x_total = -106.07 + 0 + 451.92 = 345.85 m
y_total = 106.07 - 85 + 316.23 = 337.3 m
qrt((345.85)^2 + (337.3)^2) = 476.6 m
tan^-1(337.3 / 345.85) = 46.7°
Therefore, the magnitude of the resultant displacement of the drone is 476.6 m, and the direction is 46.7° north of east.
2, v_f = v_i + a*t
v_f is the final velocity, v_i is the initial velocity (75 mph = 33.5 m/s), a is the acceleration (-0.25 m/s^2), and t is the time (15 s).
Plugging in the values, we get:
v_f = 33.5 - 0.25*15 = 29.125 m/s
To convert the final velocity to mph, we can multiply by the conversion factor:
v_f = 29.125 * 2.23694 = 65.1 mph
To find the total distance traveled, we can use the kinematic equation:
d = v_it + 0.5a*t^2
Plugging in the values, we get:
d = 33.515 + 0.5(-0.25)*(15)^2 = 498.125 m
Therefore, the final velocity of the motorcycle is 29.125 m/s (or 65.1 mph), and it traveled a total distance of 498.125 m during the 15 s timeframe.
