Juan rides his horse with a constant
speed of 18 km/h. How far can he travel
in 1/2 hour?

Answer:

If two magnetic south poles or two magnetic north poles are brought near each other, the magnetic force is repulsive and the magnets will push against each other in opposite directions. If opposite poles are brought near, it is attractive. But the fundamental origin of the magnetic field is moving charge.

Answer:

76

Explanation:

The speed is 76 miles per hour your welcome!!

The mass of the given will be 20kg.

By using formula,

force = mass x acceleration

mass = force / acceleration

mass = 400 N / 20m/s²

mass = 20 Kg

Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.

Any process where the velocity changes is referred to as acceleration. There are only two ways to accelerate: changing your speed or changing your direction, or changing both. This is because the velocity is both a speed and a direction.

The previous value of a portfolio that must be reattained before a hedge fund can charge incentive fees is known as a high watermark.

In the context of hedge funds, incentive fees are performance-based fees charged by fund managers. These fees are typically calculated as a percentage of the fund's profits above a certain threshold. The high water mark is an important concept that determines when incentive fees can be charged.

The high water mark refers to the highest previous value of the portfolio that has been achieved. It represents the peak value that the portfolio has reached in the past. In order for a hedge fund to charge incentive fees, the current value of the portfolio must exceed this high water mark. This ensures that investors are only paying fees on the profits made by the fund manager after surpassing previous performance levels.

By using the high water mark, hedge funds align their interests with those of the investors. Fund managers are incentivized to generate positive returns and recoup any losses before charging performance-based fees. This mechanism helps protect investors from paying fees on underperforming periods and encourages fund managers to focus on achieving new highs in portfolio value.

The generator induces a 900 V peak voltage.  the peak voltage will be at its highest when the coil's breadth is at its greatest.

The formula: yields the peak voltage induced in an AC generator.

\(Vp = 2fNAB.\)

In this equation, Vp stands for the peak voltage, f for the armature's rotational frequency, N for the number of turns, A for the coil's area, and B for the magnetic field's intensity.

f = 20 Hz, N = 200, A = l x w (where l is the length and w is the breadth of the rectangular coil), and B = 1.5 T are the relevant parameters in this case.

Given that the width and length of the rectangular coil are equal, the area of the coil can be calculated as follows:

\(A = l x w = 2w x 2w\)

The replacement of value, we obtain:

\(Vp is equal to 2 x 20 x 200 x 2 w x 1.5.\)

\(Vp = 900w^2π\)

We are unable to calculate the precise value of the peak voltage since we are unsure of the width of the coil's exact value. The peak voltage is, nevertheless, directly proportional to the square of the coil width, according to this statement. As a result, the peak voltage will be at its highest when the coil's breadth is at its greatest.

Answer:

The bicyclist goes at 5 m/s

Explanation:

Motion With Constant Acceleration

It's a type of motion in which the velocity of an object changes uniformly in time.

The equation that rules the change of velocities is:

\(v_f=v_o+at\)

Where:

a   = acceleration

vo = initial speed

vf  = final speed

t    = time

It's given a bicyclist is traveling at v0=+25 m/s and decelerates at \(a=-4\ m/s^2\). We are required to calculate the speed after t=5 seconds.

Applying the formula:

\(v_f=25+(-4)*5\)

Explanation:

KE = ½ mv²

KE = ½ (150 kg) (3 m/s)²

KE = 675 J

The kinetic energy of a 150 kg bear running at 3 m/s would be 67.5 Joules.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy

ME = KE + PE

As given in the problem we have to calculate the kinetic energy of a 150 kg bear running at 3 m/s

K.E =?

m = 150 kg

v = 3 m/s

The total kinetic energy is given by the formula

KE = 1/2mv²

By substituting the respective values in the formula of kinetic energy

K.E =?

m = 150 kg

v = 3 m/s

KE =1/2×150×3²

KE= 67.5

Thus, The kinetic energy of a 150 kg bear running at 3 m/s would be 67.5 Joules.

The magnitude of the force exerted on the door by the woman is equal to the magnitude of the force exerted on the woman by the door.

Newton's third law of motion states that "For every action, there is an equal and opposite reaction." This means that when two objects interact, they apply equal and opposite forces on each other. The forces are proportional in magnitude and opposite in direction. This law helps to explain how objects react to forces and how forces result in motion

The door and the woman are interacting forces, and the magnitude of the force that each exerts on the other is equal. However, the direction of the forces is opposite. The woman is pushing the door in one direction, while the door is pushing back on the woman in the opposite direction.

(a). The temperature requires to boil is,

I think it's asteroids but I'm not 100% sure

Answer:

The right answer is "1.369 m/s²".

Explanation:

The given values are:

Distance (s)

= 260 m

Initial speed (u)

= 26 m/s

Reaction time (t')

= 0.51 s

During reaction time, the distance travelled by locomotive will be:

⇒  \(s'=ut'\)

        \(=26\times 0.51\)

        \(=13.26 \ m\)

Remained distance between locomotive and car:

⇒  \(x=s-s'\)

         \(=260-13.26\)

         \(=246.74 \ m\)

Now,

The final velocity to avoid collection is, V = 0 m/s

From third equation of motion:

⇒  \(V^2=u^2+2ax\)

On putting the estimated values, we get

⇒  \(0=(26)^2+2\times a\times 246.74\)

⇒  \(0=676+493.48a\)

⇒  \(493.48a=-676\)

⇒            \(a=-\frac{676}{493.48}\)

⇒            \(a=1.369 \ m/s^2\)

The sum total of all forces which are acting on an object is known as the net force. A mass can accelerate due to the net force.

The net force can be defined as the sum total of all the forces which are acting on an object. Net force can accelerate a mass. Some other force also act on an object either at rest or motion.

Here, r₁₂ = 0.550m r₂₃ = 0.550m. Then the distance from the first charge to the third one will be:

r₁₃ = r₁₂ + r₂₃ = 0.550 + 0.550 = 1.1m

According to the Coulomb's law, the net force on particle q₂ will be equal to the sum of the forces on particle q₂ from the particle q₁ and q₃.

F₃+ = F₁₃ +F₂₃ = q₁q₂/r²₁₃ + k q₃q₂/r²₂₃

Where, k = 9 × 10⁹ N m²/C²

Substituting numerical values, we obtain:

F₃ = 9 × 10⁹ (-66.3 × 10⁻⁶)(-43.2 × 9 × 10⁻⁶)/ 1.45² + 9 × 10⁹ × 108 × 10⁻⁶ (-43.2 × 10⁻⁶) / 0.550²
