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.

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.

Write the word conductor or insulator on each of the lines. Then infer which type of material is inside the holes in the outlet. Explain you answer.
( will mark brainliest if you help.)
The required choice is for both the lines are conductor and conductor.
What is conductor and insulator?A conductor is something that easily allows current to flow through it. As an example, consider metal or any other metal. An insulator is something that does not allow current to travel through it. Polyurethane is an example.
Here,
Inside each socket are two pairs of metal strips that are engineered to bend and flex but return to their original shape when pressure is released. Each pair of strips is linked to one of your power lines (either hot or ground).
When you insert the wall plug, springy brass fingers hold the plug prongs, allowing you to connect to your home's electrical system.
Thus, the required choice is for both the lines to be conductor and conductor.

Anytime there is height, the object must have...
a
kinetic energy
gravitational potential energy
GPE & KPE
C
Od
elastic potential energy
Answer:
gravitational potential energy.
Explanation:
Gravitational potential energy (GPE) can be defined as an energy possessed by an object or body due to its position above the earth surface.
Mathematically, gravitational potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where,
G.P.E represents gravitational potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
This ultimately implies that, anytime there is height, the object must have gravitational potential energy.
Hence, an object possesses gravitational potential energy due to its height (position) and the earth's gravitational force.

Answer:
Total distance traveled = 9 m
Explanation:
Given:
Distance travel towards north = 3 meter
Distance travel towards south = 6 meter
Find:
Total distance traveled
Computation:
Total distance traveled = Sum of total distance
Total distance traveled = Distance travel towards north + Distance travel towards south
Total distance traveled = 3 m + 6 m
Total distance traveled = 9 m
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

Compare and contrast the SI and the English systems of measurement.
Answer:
The international system of units otherwisely known as SI is widely used and accepted all over the globe while English system of measurement is only used by the British this limits their usage as it is applied in few part of the world which is Britain.
Both units are form of measurement being used for evaluating measurement
Explanation:
Answer:Both systems are used to numerically describe measurement. The SI system is based on the number 10 as well as multiples and products of 10. This makes it much easier to use, and so it has been the accepted system in scientific and technical applications
Explanation:The English system is more complicated as relationships between units of the same quantity aren’t uniform.
A rocket blasts off from the Earth's surface. During the initial phase of flight, the engine of the rocket burns fuel at a rate α, which creates thrust by expelling exhaust gas downward with velocity β relative to the velocity of the rocket. The thrust from the engine provides an additional upward force on the rocket of magnitude αβ. By Newton's 2nd Law, the equation governing the motion of the rocket while the rocket is burning fuel is
Answer:
αβ = Ma
Explanation:
By Newton's 2nd Law, the equation governing the motion of the rocket while the rocket is burning fuel is
αβ = Ma where α = rocket's fuel burning rate, β = relative to the velocity of the rocket, M = instantaneous mass of the rocket and a = acceleration of rocket.
