Hi there!

Recall the equation for the magnetic field of a wire (assuming infinite):

[tex]B = \frac{\mu _0 i_{encl}}{2\pi r}[/tex]

B = Magnetic field (T)
μ₀ = Permeability of Free Space (Tm/A)

i = enclosed current (A)
r = distance from wire (m)

From the equation, we can see that there is a DIRECT relationship between the current and the magnetic field.

Therefore, if the current is increased by a factor of 3, the FIELD will also be increased by a factor of three.

Hi there!

We can use the following equation for a simple pendulum:

[tex]T = 2\pi \sqrt{\frac{L}{g}}[/tex]

T = Period (4.89 s)
L = length (? m)
g = acceleration due to gravity (9.8 m/s²)

Rearrange the equation to solve for L.

[tex]T^2 = 4\pi ^2 \frac{L}{g}\\\\L = \frac{gT^2}{4\pi ^2}[/tex]

[tex]L = \frac{(9.8)(4.89^2)}{4\pi^2} = \boxed{5.936 \frac{m}{s}}[/tex]

A pendulum is a body hanging from a fixed point that swings back and forth under the effect of gravity. The length of a pendulum that has a period of 4.89 seconds is 5.936 meters.

A pendulum is a body hanging from a fixed point that swings back and forth under the effect of gravity. Pendulums are employed to govern the movement of clocks because the time interval for each full oscillation, known as the period, remains constant.

Given that the time period is 4.89 seconds, therefore, the length of the pendulum can be written as,

[tex]\rm T = 2\pi \sqrt{\dfrac{L}{g}}\\\\4.89 = 2\pi \sqrt{\dfrac{L}{9.81}}\\\\L = 5.936\ m[/tex]

Hence, the length of a pendulum that has a period of 4.89 seconds is 5.936 meters.

I = Q / t          definition of current I

Q = i t = 10 Coul/sec * 60 sec = 600 Coul

A 10-A current is maintained in a simple circuit with a total resistance of 209 ohms, then the net charge passes through any point in a circuit during a 1-minute interval would be 6000 Coulombs.

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.

Electric current is defined as the charge per unit of time.

The mathematical relation between current and the electric charge

I =Q/T

Let us first convert the time period of minutes into seconds

1 min = 60 seconds

10  min = 10*60 seconds

            =600 seconds

Q = I*t

   =10*600

   =6000 Amperes

Thus, the net charge that passes through any point in a circuit during a 1-minute interval would be 6000 Amperes.

Then the algebraic sum of the moment of all the forces about any point is equal to the moment of the resultant force about the same point

If a number of coplanar forces acting on a particle are in equilibrium. then the moment of their resultant is equal to the sum of their individual moment.

If a number of co-planar forces operating on a particle are in equilibrium, the algebraic sum of their moments about any point equals the moment of their resultant force about the same point, according to the law of moments.

Hence If a number of coplanar forces acting on a particle are in equilibrium. then the moment of their resultant is equal to the sum of their individual moment.

The net torque on this system is (ml2g-ml1g)k

This refers to the type of force that causes rotation in objects which has mass and is a twisting force

Based on the complete question, we can see the given parameters:

The torque due to farther mass above the pivot is ml2gk

The torque due to nearer mass about the pivot is ml1gk

Therefore, the net torque is (ml2g-ml1g)k

The net torque on this system in which two blocks each of mass m are attached to the ends of a massless rod, above pivot, is (ml₂g-ml_₁g)\hat k.

The torque of a body is the rate of change of angular momentum of the body. Torque is the product of moment of inertia and the angular acceleration.[tex]\tau =I\times \alpha[/tex][tex]\tau=mlg[/tex]

Here, (I) is the moment of inertia and (α) is the angular acceleration.

Two blocks each of the mass m are attached to the ends of a massless rod which pivots as shown in fig.

Initially, the rod is held in the horizontal position and then released. When, the mass was kept at farther to pivot, then the value of torque is,

[tex]\tau=ml_2g\hat k[/tex]

When, the mass was kept at nearer to pivot, then the value of torque is,

[tex]\tau=-ml_1g\hat k[/tex]

Thus, the net torque on this system above pivot is,

[tex]\tau=ml_2g\hat k+(-ml_2g\hat k)\\\tau=(ml_2g-ml_1g)\hat k[/tex]

Thus, the net torque on this system in which two blocks each of mass m are attached to the ends of a massless rod, above pivot is (ml₂g-ml_₁g)\hat k.

The stopwatch will be the most useful in determining the kinetic energy of a 50 g battery- powered car traveling a distance of 10 m.

Kinetic energy is the energy of a body possessed due to motion.

This means that for an object to possess kinetic energy, it must be in motion.

The kinetic energy is measured in Joules, which is a product of the mass of the substance and the time taken to travel a distance.

A stopwatch is an instrument used to measure time as one of the components of kinetic energy.

Therefore, the stopwatch will be the most useful in determining the kinetic energy of a 50 g battery- powered car traveling a distance of 10 m.

Answer:

See below ↓

Explanation:

Step 1 : Diagram

Step 2

⇒ ΔE = 0

⇒ Eₙ - Eₓ = 0

⇒ Eₙ = Eₓ

⇒ Kₙ + Uₙ + Pₙ = Kₓ + Uₓ + Pₓ

⇒ Uₙ + Pₙ = Uₓ + Pₓ

Step 3

⇒ Uₙ + Pₙ = Uₓ

⇒ Uₙ + Pₙ = 0

⇒ 1/2kxₙ² + mgyₙ = 0

⇒ 1/2kxₙ² = -mgyₙ

⇒ 1/2kA² = -mg(-A)

⇒ 1/2kA² = mgA

⇒ [1/2kA = mg]

Step 4

⇒ F = kA

⇒ k = F/A

⇒ Plug 'k' into the equation found at the end of Step 3

⇒ 1/2(F/A)(A) = mg

⇒ 2F = mg

⇒ F = 2mg (a)

Step 5

⇒ F - mg = 0

⇒ F = mg

⇒ F = -kx

⇒ kyₙ = mg

⇒ yₙ = mg/k

⇒ yₙ = 0.25 x 9.8 / -10

⇒ yₙ = -0.245 m

⇒ yₙ = A

⇒ yₙ = 0.245 m (b)
