A model depicts two balloons of the same size with identical negative charges being moved toward one another at the same speed. How will the balloons interact with each other?
A.) They will repel, moving in opposite directions at the same speed.
B.) They will repel, moving in the same direction at different speeds.
C.) They will attract, moving in the same direction at the same speed.
D.) They will attract, moving in opposite directions at different speeds.
Answer:
A.) They will repel, moving in opposite directions at the same speed.
Explanation:
The correct option is - A.) They will repel, moving in opposite directions at the same speed.
As because the two balloons have identical charge and moving towards each other , so they repel each other (as we know like charges repel each other)
Option A is correct. (A.) They will repel, moving in opposite directions at the same speed. Because the megnitude and nature of the charge are same.
What is Columb's law?The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.
They will repel, moving in opposite directions at the same speed. Because the megnitude and nature of the charge are same.
Hence option A is correct. (A.) They will repel, moving in opposite directions at the same speed.

The density of water is 1.0g/cm3. How many kilograms of water does a submerged 120-cm3 block displace? Recall that 1.0 kg weighs 9.8 N on Earth. What is the buoyant force on the block?
Answer:
The mass of the liquid displaced is 0.12 kgThe buoyant force on the block is 1.176 N.Explanation:
Given;
density of water, ρ = 1.0 g/cm³
volume of the submerged block, V = 120 cm³
Applying Archimedes principle;
The mass of the liquid displaced is calculated as;
m = ρV
m = 1.0 g/cm³ x 120 cm³
m = 120 g
m = 0.12 kg
The buoyant force on the block is calculated as;
F = mg
F = 0.12 x 9.8
F = 1.176 N
Therefore, the buoyant force on the block is 1.176 N.

If a 400 watt motor is left on for 10 minutes, assuming no energy is lost to friction, how fast could a 100 kg cart be moving?
Answer:
69.28 m/s
Explanation:
From the question given above, the following data were obtained:
Power = 400 Watt
Time (t) = 10 minutes
Mass (m) = 100 Kg
Velocity (v) =?
Next, we shall convert 10 mins to seconds (s). This can be obtained as follow:
1 min = 60 s
Therefore,
10 mins = 10 × 60
10 mins = 600 s
Next, we shall determine the energy. This can be obtained as follow:
Power = 400 Watt
Time (t) = 600 s
Energy (E) =?
E = Pt
E = 400 × 600
E = 240000 J
Finally, we shall determine how fast the cart is moving. This can be obtained as illustrated below:
Mass (m) = 100 Kg
Energy (E) = Kinetic energy (KE) = 240000 J
Velocity (v) =?
KE = ½mv²
240000 = ½ × 100 × v²
240000 = 50 × v²
Divide both side by 50
v² = 240000 / 50
v² = 4800
Take the square root of both side
v = √4800
v = 69.28 m/s
Thus, the cart is moving with a speed of 69.28 m/s
A light source emits light with dominant wavelengths in the range of 650 to 690 nm. what is the principle color of light emitted by the source?
Answer:
Please see below as the answer is self-explanatory.
Explanation:
The visible range extends roughly from 400 nm (violet) to 700 nm (red).Below the violet is the ultra-violet spectrum (with higher energy) and above red, we have the infra-red spectrum.The wavelengths in the range of 650 to 690 nm have red as the dominant color.Fracture zones are cracks on the ocean floor that horizontally offset mid-ocean ridges, Fracture zones typically run perpendicular to mid-ocean ridges.

A 25N force is applied to a bar that can pivot around its end. The force is r=0.75 m away from the end of an angle at 0= 45. what is the torque on the bar?
a. What is the direction of the torque.
b. what is the sign of the direction of the figure.
Answer:
The answer is B. I had a question like this last week in my physics practice exam. dont have alot of time so I cant explain right now
Explanation:
The torque on the bar will be - 13.26 Nm. And the sign of the direction of the figure will be inside the plane.
What is the torque?Torque is the rotating counterpart of force in physics and mechanics. The instant of force is another name for it. It illustrates how a force can cause a change in the body's rotational movement.
Let 'F' be the force and 'r' be the distance.
The torque is the vector product of the force and radius which is given as,
T = r x F
T = r · F · sin θ
A 25N power is applied to a bar that can turn around its end. The power is r = 0.75 m away from the finish of a point at θ = 45°.
Then the torque is calculated as,
T = - 0.75 x 25 x sin 45°
T = - 13.26 Nm
The sign of the direction of the figure will be inside the plane.
More about the torque link is given below.

1. What is the equivalent resistance in this circuit?
2. What is the current in this circuit?
1. The equivalent resistance in a series circuit, like the one shown, is given by the general equation
[tex]R_{S} = R_1 + R_2 + R_3 + . . . + R_{N-1} + R_N = \sum_{i=1}^N R_i[/tex]
where N is the number of resistors in series. Here, there are four resistors in series. Using our equation with N = 4, we obtain
[tex]R_{S} &= R_1 + R_2 + R_3 + R_4 \\ R_{S} = 2.0 \, \Omega + 3.0 \, \Omega + 4.0 \, \Omega + 6.0 \, \Omega \\ R_{S} = 15.0 \, \Omega.[/tex]
2. The current in this series circuit is equal to the voltage divided by the equivalent resistance (a relationship you can derive from Ohm's law):
[tex]I = \frac{V}{R_{S}} = \frac{45 \, V}{15.0 \, \Omega} = 3.0 \, A. \nonumber[/tex]

Lucas is carrying his rock collection into class. He carries 30 pounds of rare rocks 15 feet into Classroom 6. It takes him
3 minutes to get them into the classroom What is Lucas's speed and level of work? Be sure to show your work with
equations as part of your answer.
Answer:
10 and 5
Explanation:
Answer:
It is given that,
Force, F = 30 pounds = 133.4 N
Distance, d = 15 feet = 4.572 m
Time taken, t = 3 minutes = 180 seconds
Lucas's speed is given by the ratio of total displacement divided by total time taken. It is given by :
s = 0.0254 m/s
So, her speed is 0.0254 m/s.
Work done, W = F . d
W = 133.4 N × 4.572 m
W = 609.90 J
or
W = 610 J
Hence, this is the required solution.

How is an electromagnetic field produced? Please I need answers
Answer:
by potential difference and electron gun
Explanation:
a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
Answer:
Electromagnetic field can be produced by the superposition of electric field and magnetic field.
Explanation:
What is superposition ?When two or waves propagate in a medium without affecting each other , then at any instant the displacement of a particle will be equal to the vectorial sum of the displacements due to the waves.
Electromagnetic field can be produced by electric arc.It cab be produced by LC Circuits.Hence Electromagnetic field can be produced by L-C CIRCUITS.
