Answer:

To solve this problem, you can use the principle of transverse static equilibrium. This states that the sum of the forces acting on an object must be equal to zero for the object to be in equilibrium. In this case, the forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod.

First, you can find the weight of the rod by multiplying its mass by the acceleration due to gravity:

Wrod = mrod * g

= 0.7 kg * 9.8 m/s^2

= 6.86 N

Next, you can find the weight of the 4.0-kg mass by multiplying its mass by the acceleration due to gravity:

W1 = m1 * g

= 4.0 kg * 9.8 m/s^2

= 39.2 N

You can find the weight of the 2.0-kg mass in the same way:

W2 = m2 * g

= 2.0 kg * 9.8 m/s^2

= 19.6 N

To find the tension in the strings, you can use the principle of transverse static equilibrium. The forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod. You can represent these forces as vectors acting at the points where the strings are attached to the rod. The vectors representing the tension in the strings will be equal in magnitude but opposite in direction. The vectors representing the weight of the rod and the masses will act vertically downward.

Answer:

In the medium where the angle of incedence is 10°

Explanation:

This is because angle of incedence is directly proportional to refractive index of a medium.

Since refractive index is inversely proprtional to speed of light in medium, it will be the case.

The identical formula for the two angles is Asin(b),Asin(b).

The general word for interference effects involving edges or apertures is diffraction. In waves with longer wavelengths than those of light, diffraction is more common. Diffraction, for instance, is what causes sound to swell when it goes through a doorway or bend around corners. Diffraction causes water waves along a rocky coast to widen as they pass through the rocks. Usually, Fresnel and Fraunhofer diffraction regimes are distinguished.

Fresnel diffraction is the regime in which the diffracted waves are observed relatively close to the site of the diffraction (in comparison to the size of the item causing the diffraction). Working with Fresnel diffraction is typically very challenging. The Fraunhofer diffraction regime is the more manageable of the two.

angle 1 = asin(λb),

angle 2 = asin(−λb)

The ball requires a total of zero work to go to the right at 24 m/s.

Take into account the ball's kinetic energy.

Vi = -24 ms-1 for the initial velocity

Final velocity: vf = +24ms⁻¹

K = 12mvf²- 12mvi² = 12m(vf² - vi²) = 12m(242 - 242) = 0,

meaning that the ball does not undergo any effort.

As an alternative, think about the effort made to stop the ball.

W1 = ½m(0 – 24²) = 0.5 × 0.06 × –576 = –17.28J

Work required to accelerate the ball from rest to +24 milliseconds per second was W2 = 12m(242 - 0) = 0.5 0.06 576 = +17.28 J.

Therefore, the sum of the work is W = W1 + W2 = -17.28 + 17.28 = 0 J.

Answer:

RT = 341.62 Ohms

Explanation:

Given the following data;

R1 = 420 Ohms

R2 = 320 Ohms

R3 = 160 Ohms

To find the equivalent resistance;

From the circuit, we can see that R1 and R2 are connected in parallel;

Mathematically, the total equivalent resistance of resistors connected in parallel is given by the formula;

[tex] RT = \frac {R1*R2}{R1 + R2} [/tex]

Substituting into the formula, we have;

[tex] RT1 = \frac {420*320}{420 + 320} [/tex]

[tex] RT1 = \frac {134400}{740} [/tex]

RT1 = 181.62 Ohms

Next, we resolve the resistors to form a series circuit.

RT = RT1 + R3

RT = 160 + 181.62

RT = 341.62 Ohms

Hence, the ladder top to touch ground the ladder base should pull back a distance of ( 6 - 3 ) = 3 meters on ground As the rate of sliding of base of ladder is 0.5 meter per second , it takes a time of [  3/ (0.5) ] = 6 seconds.

What is Distance? Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Distance measures length. For example, the distance of a road is how long the road is. In the metric system of measurement, the most common units of distance are millimeters, centimeters, meters, and kilometers.

Answer: Sound wave diffracts more.

Explanation: Width of gap d  is smaller than wavelength λ of the gap.

You can estimate it from  equation  d sin α = n λ

The constant n is order of diffraction, n = 0,1,2,..

sin α = n λ / d   is greater when  λ/d is greater.

Sound wave will tend diffract more through a narrow gap that is about 1 centimeter wide.

Diffraction is the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wave like properties.

Answer:

350.72 m/s

Explanation:

Formula for velocity of wave is;

v = fλ

Where;

v is speed

f is frequency

λ is wavelength

We are given;

f = 512 Hz

λ = 0.685 m

Thus;

v = 512 × 0.685

v = 350.72 m/s

The average speed of the car is 24 m/s. The average speed of the car is therefore below 25.0 m/s.

The description of rapidity. a change in the location of an object in either direction or speed. How fast something is going is determined by the distance travelled and the time required to cover that distance. Speed is a scalar quantity since it just has an arrow-like direction and no magnitude.

The entire movement of an item, independent of direction, is called distance. Distance may be characterized as the quantity of ground covered, regardless of the starting or finishing points of an item.

distance (d) = 9 miles = 14.4841 km

d = 14484.1 m

1 miles = 1609.34 m

t₁= 14484.1/ 20

 = 724.2 sec

t₂= 14484.1/ 30= 482.8 sec

total time ( t) = t+t

t= 724.2+ 482.8 = 1207 sec

Vavg = 2d/t= 2*14484.1/1207

Vavg = 24m/s

24< 25

lessthan 25m/s

car average speed (Vavg) = 24 m/s.

The frequency of the cart's motion for a distance of 10.0 meters is 0.075 Hz (Hertz), which means the cart completes 0.0775 round trips per second.

1) Period (T):

The period (T) is the time taken for one complete round trip. The cart travels from one end to the other and back in one round trip.

T =  (distance/speed)

T = (10.0 / 0.75 )

T = 13.33 seconds

So, the period of the cart's motion for a distance of 10.0 meters is approximately 13.33 seconds.

2) Frequency (f):

The frequency (f) is the number of complete round trips per unit time. It is the reciprocal of the period.

f = 1 / T

f = 1 / 13.33

f =  0.075 Hz

So, the frequency of the cart's motion for a distance of 10.0 meters is approximately 0.075 Hz (Hertz), which means the cart completes approximately 0.0775 round trips per second.

The acceleration of the particle at t=0 is zero because the particle is in rest position and did not moving at any of the instance or travelling at an uniform speed through out the whole journey or yet did not start from the source point.

Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction. Acceleration of the body that we can consider is the increasing value of the velocity of any object at a constant rate and that of wee can calculate.

Friction is the resistance to motion that results from two objects rubbing against one another. Two objects rubbing against one another causes friction. Motion is opposed by friction, which works against the motion.

When an object slides over another object, friction slows it down. As a result, energy is used. However, the energy does not fade away.
