A) gravity.
B) interior rotation rates.
C) orbital periods.
D) orbital radius.
E) ring system diameters.
Answers
Studying the magnetospheres of the Jovian planets has allowed us to measure their interior rotation rates. The correct option is B.
The magnetosphere is the region surrounding a planet where its magnetic field interacts with the solar wind, a stream of charged particles emitted by the Sun.
By analyzing the behavior of charged particles within the magnetosphere and their interactions with the planet's magnetic field, scientists can gain insights into the planet's internal dynamics, including its rotation rate.
Changes in the magnetic field and the motion of charged particles provide valuable data for determining the rotational characteristics of the Jovian planets.
This information helps scientists understand the complex dynamics and processes occurring within these giant planets.

A playground slide is inclined 40°. If a boy with a mass of 32 kg slides down for -3meters. How much work is done by gravity on the boy?
Answers
Answer:
the work done by gravity on the boy is 604.62 J
Explanation:
Given;
distance the boy slides, d = 3 m
angle of inclination of the playground, θ = 40⁰
mass of the boy, m = 32 kg
The vertical height, h, above the ground through which the boy falls represents the height of the triangle which is the opposite side.
The distance through which the boy slides, d, represents the hypotenuse side of the right triangle.
\(sin \theta = \frac{opposite }{hypotenuse} \\\\sin \theta = \frac{h}{d} \\\\h = dsin\theta\\\\h = 3 \times sin(40^0)\\\\h = 1.928 \ m\)
The work done by gravity on the boy is calculated as;
W = P.E = mgh
= 32kg x 9.8m/s² x 1.928m
= 604.62 J
Therefore, the work done by gravity on the boy is 604.62 J

Two point charges are placed at the following points on the x-axis. +2.0 C at
×=0, -3.0.C at 0.40m. Find the electric field strength at 1.20m?
Answers
The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.
To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:
\($$F=k\frac{q_1q_2}{r^2}$$\)
where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:
\($$E=\frac{kq}{r^2}$$\) where k is the Coulomb constant.
So, let's calculate the electric field due to each charge separately and then add them up:
For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)
For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:
\($$E_2=\frac{kq_2}{r^2}\)
\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)
The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.
To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)
Substituting the values of E1 and E2:
\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)
net comes out to be -1.5×10⁴ N/C.
Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

Your friend is sitting on another train traveling west at 29 m/s. as you walk toward the back of your train at 3.7 m/s, what is your velocity with respect to your friend?
Answers
The relative velocity with respect to my friend is 32.7 m/s.
We need to know about relative velocity to solve this problem. The relative velocity depends on the object and observer velocity. It can be written as
v = vo ± v'
where v is relative velocity, vo is object velocity and v' is observer velocity.
From the question above, we know that
vo = 29 m/s
v' = 3.7 m/s
The velocity will be added each other because the direction of the observer is different from the object.
v = vo + v'
v = 29 + 3.7
v = 32.7 m/s
Hence, the relative velocity with respect to my friend is 32.7 m/s.

how many milliseconds after the switch moves does vo equal -90 v ? express your answer in milliseconds to three significant figures.
Answers
To answer this question, we need to consider the equation that relates the voltage across a capacitor to its charge and capacitance:
V = Q/C
where V is the voltage, Q is the charge on the capacitor, and C is the capacitance.
At the instant the switch is moved, the capacitor is fully charged to 100 V. When the switch is moved, the capacitor discharges through the resistor R with a time constant of R*C. We can use the equation:
V = Vo*e^(-t/RC)
where Vo is the initial voltage across the capacitor (100 V), V is the voltage at time t, and RC is the time constant (R*C).
We want to find the time it takes for V to reach -90 V. Setting V = -90 V, we get:
-90 = 100*e^(-t/RC)
Solving for t, we get:
t = -RC*ln(0.9)
Plugging in the values for R and C, we get:
t = -10^4*10^-6*ln(0.9) = 6.93 ms
Therefore, it takes approximately 6.93 milliseconds for the voltage across the capacitor to reach -90 V after the switch is moved.

Answers
The wall is positively charged, whereas it is negatively charged. If a woollen fabric is not used to massage it, it will not do so. When the sand was drawn inside the balloon, the same thing occurred.
Why are balloons attracted to each other?Positive charges pull away from negative charges. The balloon will attract the wool fabric if it is not touched since it contains an equal balance of negative and positive charges. Both balloons will reject one another when they are brushed with the wool cloth because they both receive negative charges.
Why does a charged balloon attract water?Positive and negative particles make up the water.

a. Which side has the larger current magnitude and why?
b. Which side has the larger potential difference magnitude, and why?
c. Which side has the larger drift velocity magnitude, and why?
d. Answers may include both sides are the same.
Answers
In case, when two cylindrical wires of different diameters are connected in series, an emf (electromotive force) is applied across the ends.
a. The side with the smaller diameter cylindrical wire on the left will have a larger current magnitude. This is because the current density, which is defined as the current per unit cross-sectional area of the wire, is inversely proportional to the cross-sectional area of the wire. Since the left side has a smaller cross-sectional area, it will have a larger current density and therefore a larger current magnitude.
b. The potential difference magnitude is the same on both sides. This is because the potential difference between two points is determined by the emf of the battery and is independent of the wire's properties. Therefore, the potential difference between points A and B is the same on both sides of the wire.
c. The side with the smaller diameter cylindrical wire on the left will have a larger drift velocity magnitude. This is because the drift velocity of electrons in a wire is proportional to the current density, which as stated above, is inversely proportional to the cross-sectional area of the wire. Since the left side has a smaller cross-sectional area, it will have a larger current density and therefore a larger drift velocity magnitude.

Answer:
20 meters.
Explanation:
In the graph, the x-axis (the horizontal axis) represents the time, while the y-axis (the vertical axis) represents the distance.
If we want to find the distance covered in the first T seconds, you need to find the value T in the horizontal axis.
Once you find it, we draw a vertical line, in the point where this vertical line touches the graph, we now draw a horizontal line. This horizontal line will intersect the y-axis in a given value. That value is the total distance travelled by the time T.
In this case, we want to find the total distance that David ran in the first 4 seconds.
Then we need to find the value 4 seconds in the horizontal axis. Now we perform the above steps, and we will find that the correspondent y-value is 20.
This means that in the first 4 seconds, David ran a distance of 20 meters.

10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
Answers
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.
