A current carrying wire is placed in a permanent magnetic field as shown in the diagram below. Determine the direction of the force that the wire experiences.

Answer:

False.

Explanation:

provided the distance between the forces remains the same, the force will increase with increased charge, whether attractive or repulsive.

Answer:

Let R be the total distance

R²=10.4²+(8.7+2.1)²

R²=10.4²+10.8²

R²=224.8

You square root both sides

R=14.99km

If an airplane takes off, it travels 10.4 km west, 8.7 km north, and 2.1 km up, then using the Pythagorean theorem it is 14.99km from its take-off point.

Pythagoras' theorem is a fundamental theorem in mathematics that relates to the sides of a right-angled triangle. It states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In equation form, the theorem can be written as:

c² = a² + b²

Where

c =the length of the hypotenuse,

a and b = the lengths of the other two sides.

The theorem is named after the ancient Greek mathematician Pythagoras, who is credited with his discovery and proof. Pythagoras' theorem is widely used in mathematics and has many practical applications in fields such as architecture, engineering, and physics.

Here in the question

We can use the Pythagorean theorem to find the distance from the takeoff point:

Distance = √(West)² + (North+Up)²

Plugging in the given values, we get:

Distance = √(10.4)² +( 8.7 + 2.1)²

Distance ≈ 14.99km

Therefore, the airplane is approximately 14.99km away from the takeoff point.

At time t, the ball attains a height y of

y = (30 m/s) sin(53º) t - 1/2 g t²

where g = 9.80 m/s² is the magnitude of the acceleration due to gravity.

Solve for t when y = 0:

(30 m/s) sin(53º) t - 1/2 g t² = 0

t ((30 m/s) sin(53º) - (4.90 m/s²) t ) = 0

t = 0   or   (30 m/s) sin(53º) - (4.90 m/s²) t = 0

We ignore the first solution, since that refers to the moment the ball is kicked.

(30 m/s) sin(53º) - (4.90 m/s²) t = 0

(30 m/s) sin(53º) = (4.90 m/s²) t

t = (30 m/s) sin(53º) / (4.90 m/s²)

t ≈ 4.9 s

Any wave in which the motion of the medium's particles is parallel to the wave's direction is referred to as a longitudinal wave.

Imagine that a slinky is stretched out horizontally across the classroom, and that the left end of the slinky receives a pulse from the left and right vibrations of the first coil. From left to right, energy will start to move through the slinky. The individual coils of the medium will be shifted left and right as the energy moves from left to right. The medium's particles in this instance travel in a direction parallel to the pulse's. A longitudinal wave is this kind of wave. Particle motion is consistently parallel to wave motion in longitudinal waves.

A well-known example of a longitudinal wave is a sound wave moving through air.

1.00 kg of ice at -24.0°C is placed in contact with a 1.00 kg block of a metal at 5.00°C. They come to equilibrium at -8.88°C.

We can use the principle of conservation of heat to solve this problem. The heat lost by the metal must equal the heat gained by the ice.

The heat lost by the metal is given by

Q1 = m1c1ΔT1

Where m1 is the mass of the metal, c1 is its specific heat, and ΔT1 is the change in temperature.

The heat gained by the ice is given by

Q2 = m2c2ΔT2

Where m2 is the mass of the ice, c2 is its specific heat, and ΔT2 is the change in temperature.

Since the two objects come to thermal equilibrium, we can set Q1 equal to Q2

m1c1ΔT1 = m2c2ΔT2

Solving for c1, we get

c1 = m2c2ΔT2 / (m1ΔT1)

By putting these values we get

c1 = (1.00 kg)(2.06 kJ/kg·K)(-24.0°C - (-8.88°C)) / [(1.00 kg)(5.00°C - (-8.88°C))]

c1 = 0.902 kJ/kg·K

Hence, the specific heat of the metal is 0.902 kJ/kg·K.

Explanation:

We can use the equation h=16t^2 to find the height in feet for a free-falling object. The height from the bridge to the water is h=16(0.4)^2=16(0.16)=2.56 ft

Next, we use the equation v=sqrt(2gh) to determine velocity from vertical height. First we must convert feet to meters as velocity is measured in m/s. 2.56ft is about 0.78 meters. Since h=0.78m from the previous equation and g=9.81m/s^2, then your velocity is v=sqrt(2*9.81*0.78)=sqrt(15.3036)=3.911981595

Answer:

PlROCA

Explanation:

We are given a distance of 400 meters and we are asked to determine the time to cover this distance for different values of speed. Since we are asked to construct a table, we begin by setting up a column with values of speed that range from 2 meters per second to 10 meters per second, like this:

Now we need to set up another column with the values for time. To do that we will use the fact that the speed is defined as:

Where "v" is speed, "t" is time, and "d" is distance. We can solve for the distance by multiplying both sides by "t":

Now we divide both sides by "v":

Now, since the distance is fixed at 400 meters we can replace this value in the equation:

Now we have a relationship that will allow us to determine the value of the time. We just need to replace each of the values on the column for speed into the equation to get the value for the time. Replacing the first value of speed we get:

This is the first value for the column of time. The second value is obtained replacing the second value for the speed:

This is the second value. We continue like this for each of the values and we get the following table:

Now we can plot these values and we obtain the following graph:

3. The rule to calculate race time "t" for any average speed is the one that was determined previously to construct the table, this is:

4. we are asked about the change in time given a change in speed. We can calculate this by subtracting the initial time from the initial speed from the final time at the final speed, this is:

Where:

Now, the change from 2 to 4 meters per second is the following:

replacing we get:

Therefore, the time is reduced in 100 seconds. Now for an increase from 8 to 10 meters per second we get:

Replacing in the formula for change:

therefore, the time is reduced in 10 seconds. This means that the change from 2 to 4 meters per second will reduce the race time the most. This can be illustrated in the graph as it gets flatter the greater the speed is, meaning that the changes in time are reduced.

Force of Tension = (m)(g)

120 = (m)(9.8)

m = volume(density)

120 = (4/3)πr³(0.308)(9.8)

\(\frac{(120)(3)}{(pi)(0.308)(9.8)}\) = r^3

solve

The radius of the brass ball is equal to 6.94 × 10⁻² m when the tension in the wire is 120 N.

Tension can be demonstrated as the pulling force transmitted by the means of a string, or a rope or can be described as the action-reaction pair of forces acting at each end of said elements.

The tension in the wire attached to the ceiling will be given by:

T = mg ⇒m = T/g

The radius of the brass ball is given by: \(r =\sqrt[3]{\frac{3V}{4\pi } }\)

The density is given by: ρ = m/V = T/gV

V = T/gρ

Therefore, the expression for the radius can be written as:

\(r =\sqrt[3]{\frac{3T}{4\pi\rho g } }\)

Given the tension in the wire, T = 120 N

The density of the brass is = 8730 Kg/m³

\(r =\sqrt[3]{\frac{3\times 120}{4\times 3.14 \times 8730 \times 9.81 } }\)

The syllogisms constructed from the given statements are valid, except for the one syllogism identified as invalid.

Categorical syllogisms are logical arguments that involve two premises and a conclusion, all of which are categorical statements. These statements are formed using categorical propositions that involve classes or categories of objects or concepts.

Let's examine the given statements and identify the valid and invalid syllogisms:

All mumbling is murmuring: This statement indicates that the class of mumbling is entirely contained within the class of murmuring. It can be represented as "All M is M."

All mumbling is nonsensical: This statement suggests that the class of mumbling is entirely nonsensical. It can be represented as "All M is N."

No murmuring is sensical: This statement implies that there is no overlap between the class of murmuring and the class of sensical. It can be represented as "No M is S."

Now, let's construct the syllogisms using these statements:Syllogism 1:

Premise 1: All M is Mumbling

Premise 2: All Mumbling is Nonsensical

Conclusion: Therefore, All M is Nonsensical

See the answers below.

Explanation:

Momentum is defined as the product of mass by velocity, in this way we have the following equation.

\(P=m*v\)

where:

P = momemtum [kg*m/s]

m = mass = 1500 [kg]

v = velocity = 6 [m/s]

\(P = 1500*6\\P=9000 [kg*m/s]\)

Now we have to calculate the momentum of the plane when it travels at 30 [m/s].

\(P_{airplane}=m_{plane}*v_{plane}\\P_{airplane}=7800*30\\P_{airplane}=234000[kg*m/s]\)

Now this same momentum must be conserved, in such a way that the mass is increased but the velocity must decrease for the momentum to be conserved.

\(P=m_{new}*v_{new}\\234000=(7800+800)*v_{new}\\234000=8600*v_{new}\\v_{new}=27.2[m/s]\)
