A -0.00125 C charge is placed 3.62 m from a +0.00333 C charge. What is the magnitude of the electric force between them?

Answers

Answer 1

Answer:

The magnitude of the force between the charges is approximately -2,858.77 N

Explanation:

The given details are;

The magnitude of the given charges;

q₁ = -0.00125 C, q₂ = +0.00333 C

The distance between the charges, r = 3.62 m

The magnitude of the electric force between the charges, 'F', between two charged particles or objects is given as follows;

[tex]F = \dfrac{k \cdot q_1 \cdot q_2}{r^2}[/tex]

Where;

k = Constant = 9 × 10⁹ N·m²/C²

q₁ = The magnitude of charge on the first charged object = -0.00125 C

q₂ = The magnitude of charge on the second charged object = +0.00333 C

r = The distance between the charges = 3.62 m

Plugging in the values, gives;

[tex]F = \dfrac{9 \times 10^9 \ \dfrac{N \cdot m^2}{C^2} \times (-0.00125 \, C) \times (+0.00333 \, C)}{\left( 3.62 \, m \right)^2} \approx -2,858.77 \, N[/tex]

The magnitude of the force between the charges, F ≈ -2,858.77 N

A single fixed pulley is used to lift load by changing the direction of the lifting force. Even though a single fixed pulley has no mechanical gain in that, the effort applied is greater than the load, it is preferred in use since you do not have to pull or push the pulley up and down.

This is physics, not math. In the physical sciences, most numbers must be considered to be measurements. (A few are definitions.) Hence, the rules of significant figures and precision apply to the results of arithmetic operations. This problem is a good illustration of what happens when computing small differences of large numbers. We start with 3 significant figures in 0.205, and end up with 1 significant figure in 0.004.

Answers

Complete question:

A college dormitory room measures 14 ft wide by 13 ft long by 6 ft high. Weight density of air is 0.07 lbs/ft3. What is the weight of air in it under normal conditions?

Answer:

the weight of the air is 76.44 lbs

Explanation:

Given;

dimension of the dormitory, = 14 ft by 13 ft by 6 ft

density of the air, = 0.07 lbs/ft³

The volume of the air in the dormitory room = 14 ft x 13 ft x 6 ft

                                                                          = 1092 ft³

The weight of the air = density  x  volume

                                   = 0.07 lbs/ft³  x  1092 ft³

                                   = 76.44 lbs

Therefore, the weight of the air is 76.44 lbs

b) distance traveled by car assume motion of car is uniform
c) if the mass of the car is 1000kg. what is the force acting on it?
Pls help me. I'm bad in this subject. kinda need it by today​

Answers

Answer:

a. Acceleration, a = 7.5 m/s

b. Distance, S = 15 meters

c. Force = 7500 Newton

Explanation:

Given the following data;

Mass = 1000 kg

Initial velocity = 0 m/s (since it's starting from rest).

Final velocity = 54 km/h

Time = 2 secs

Conversion:

54 km/h to m/s = 54*1000/3600 = 15 m/s

a. To find the following acceleration;

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{initial speed - final speed}{time}[/tex]

Substituting into the formula, we have;

[tex] Acceleration = \frac{15 - 0}{2}[/tex]

[tex] Acceleration = \frac{15}{2}[/tex]

Acceleration, a = 7.5 m/s

b. To find the distance, we would use the second equation of motion.

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Where;

S represents the displacement or height measured in meters. u represents the initial velocity measured in meters per seconds. t represents the time measured in seconds. a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

[tex] S = 0*2 + \frac {1}{2}*(7.5)*2^{2}[/tex]

[tex] S = 0 + 3.75*4[/tex]

[tex] S = 15 [/tex]

Distance, S = 15 meters

c. To find the force, we would use the following formula;

[tex] Force = mass * acceleration [/tex]

[tex] Force = 1000 * 7.5 [/tex]

Force = 7500 Newton

A square wooden raft floats on a lake. The density of the water in the lake is 1000 kg/m². The sides of the raft are 2.0m long and the thickness of the raft is 0.20 m. The mass of the raft is 700 kg. How many barrels, each of mass 100 kg, could be placed on the raft before its surface sinks to the surface of the water?​

Answers

Answer:

1

Explanation:

V=2*2*0.2=0.8m^3

d=m/v 1000*0.8=800kg

800=700+100(n)            (n for barrels)

n=1

This question deals with the concept of buoyancy. This can be solved by calculating the buoyant force.

"1" barrels, each of mass 100 kg, could be placed on the raft before it sinks to the surface water.

First, we need to calculate the buoyant force on the raft due to water. This force is equal to the weight of the volume of water equal to the volume of the raft.

Buoyant Force = (Volume of Raft)(Density of Water)(g)

Buoyant Force = [(2 m)(2 m)(0.2 m)][1000 kg/m³](9.81 m/s²)

Buoyant Force = (0.8 m³)(1000 kg/m³)(9.81 m/s²)

Buoyant Force = 7848 N

For the raft to sink the weight of the raft combined with the weight of barrels must exceed the buoyant force. Now, we will calculate the weight of raft and barrels and equate it with the buoyant force.

[Mass of Raft + (No. of Barrels)(Mass of 1 Barrel)][g] = Buoyant Force

[700 kg + (No. of Barrels)(100 kg)][9.81 m/s²] = 7848 N

(No. of Barrels)(981 N) = 7848 N - 6867 N

[tex]No. of Barrels = \frac{981\ N}{981\ N}[/tex]

No. of Barrels = 1

The attached picture shows the concept of buoyancy.

Answers

Answer:

The teddy bear did not stop at the same time as the car because of inertia.

Explanation:

The teddy bear did not stop at the same time as the car because of inertia.

Inertia is a resistance of an object to change its state of motion so if an object is moving it will continue the movement until a force act on it, and vice-versa if an object is at rest it will continue in that state until a force act on it.              

Hence, when the teddy bear was in the back seat and the car suddenly stops, the teddy kept moving forward because that was the direction of motion of the car (the teddy bear was moving forward with the car). The force of the brakes acts on the car but not on the teddy bear (not directly), that is why this force does not change the state of motion of the teddy bear.                     

Therefore, the teddy bear did not stop at the same time as the car because of inertia.

Answer:

  (D)  4

Explanation:

The percentage error in each of the contributors to the calculation is 1%. The maximum error in the calculation is approximately the sum of the errors of each contributor, multiplied by the number of times it is a factor in the calculation.

  density = mass/volume

  density = mass/(π(radius^2)(length))

So, mass and length are each a factor once, and radius is a factor twice. Then the total percentage error is approximately 1% +1% +2×1% = 4%.

_____

If you look at the maximum and minimum density, you find they are ...

  {0.0611718, 0.0662668} g/(mm²·cm)

The ratio of the maximum value to the mean of these values is about 1.03998. So, the maximum is 3.998% higher than the "nominal" density.

The error is about 4%.

_____

Additional comment

If you work through the details of the math, you will see that the above-described sum of error percentages is just an approximation. If you need a more exact error estimate, it is best to work with the ranges of the numbers involved, and/or their distributions.

Using numbers with uniformly distributed errors will give different results than with normally distributed errors. When such distributions are involved, you need to carefully define what you mean by a maximum error. (By definition, normal distributions extend to infinity in both directions.) While the central limit theorem tends to apply, the actual shape of the error distribution may not be precisely normal.
