The frequency of system A determined based on given graph is 0.25

The interval between two consecutive cycles is referred to as the period, also known as the periodic time, of a periodic oscillation of a quantity. Time, or T, is defined as the period of oscillation, with T = 2 or T = 2/. The formula f = 1/T = /2 gives the reciprocal of the period, or the frequency f, in oscillations per second.

Based on the graph:

In system A; 3 wavelength in 12 secs

              for time for 1 wavelength => 12/3 = 4 sec

Thus, frequency => 1/t = 1/4 => 0.25

The wavelength and frequency components of the wave speed formula are given by the equation: v = f. where v denotes the wave's speed. The wave's frequency is f.

If the direction of the applied force is reversed on a block sliding on a horizontal surface, the force of kinetic friction between the block and the surface will also be reversed.

The force of kinetic friction will now act in the opposite direction of the applied force, and its magnitude will remain the same (0.5 N). As a result, the net force acting on the block will be the difference between the applied force and the force of kinetic friction, which will determine the block's acceleration. The block will slow down and eventually stop moving, as the force of kinetic friction will be greater than the applied force in this case.

The time taken by the electron from one plate to reach the other plate is 1.12 x 10⁻¹⁷ s

Two metal plates separated by the distance = 15 cm

                                                                          = 0.15 m

The electric field between the plates = 3 x 10³ N/C

The mass of the electron = 9.1 x 10⁻³¹ kg

The charge of the electron = 1.6 x 10⁻¹⁹ C

The time taken by the electron to hit the other plate can be found using the formula,

where d is the distance between the plate

           a is the acceleration of the electron

           t is the time taken by the electron

          v is the velocity of the electron.

Let us find the acceleration of the electron

             a = E/m

where E is the electric field of the electron

           m is the mass of the electron

             a =  3 x 10³ / 9.1 x 10⁻³¹

                =  3.27 x 10³³m/s²

Let us substitute the known values in the distance equation, we get

             d = 1/2at² + vt

         0.15 = 1/2 x 3.27 x 10³³ x t² x 0t [ the initial velocity of the electron is zero]

             t² = 2 x 0.15 / 3.27 x 10³³

                 = 0.3 / 3.27 x 10³³

                 =  0.0917 x 10⁻³³

                 = √ (0.0917 x 10⁻³³)

The past tense of the verb hang, which means "to suspend or be suspended," is "to hold." When it implies "to kill someone by tying a rope attached from above and removing the supporting from beneath," the past tense of the verb to hang is "to hang someone."

From the diagram,

were, W₁ = m₁g = 0.4×9.8 = 3.92 N ( Where m₁ = 0.4 kg and g = 9.8

Velocity at which the car can take the curve without skidding to the outside of the curve is approximately 29.5 m/s.

To determine the speed at which the car can take the curve without skidding to the outside of the curve, we need to calculate the maximum force of static friction that can act on the car as it goes around the curve.

The maximum force of static friction can be found using the formula:

f_max = friction_coefficient * f_norm

where f_max is the maximum force of static friction, friction_coefficient is the coefficient of static friction between the tires and the pavement (0.87), and f_norm is the normal force acting on the car.

The normal force can be found by calculating the centripetal force acting on the car as it goes around the curve, which can be found using the formula:

f_cent = m * a_cent

where f_cent is the centripetal force, m is the mass of the car (1091 kg), and a_cent is the centripetal acceleration, which can be found using the formula:

a_cent = v² / r

where v is the velocity of the car and r is the radius of the curve (36 m).

Substitute the value of a_cent in the formula for f_cent

f_cent = m * (v² / r)

Also we know that the maximum force of static friction is equal to the normal force acting on the car

f_max = f_norm = m * (v² / r)

Now we know friction_coefficient * f_norm = m * (v² / r)

so we can substitute the value of friction_coefficient and m and r

0.87 * m * g * sin(25) = m * (v² / 36)

v = √(0.87 * 9.8 * 36 * sin(25))

v = 29.5m/s

Therefore, the velocity of the car without skidding outside the curve is 29.5m/s

The mass would gain twice the kinetic energy it did in the scenario above if the spring were compressed by 14.1 cm.

A particle or perhaps an item that is currently motion has a type of energy called kinetic energy. An item acquires kinetic energy when work, which involves the transmission of energy, is performed on it by exerting a net force.

A spring's energy reserve is proportional to the square of the compression, x.

PE of compression = 0.5kx^2 where k is a constant to do with how easy it is to compress the spring.

So 0.5d^2 gives a KE of value Q

If you double Q you get 2Q and get 0.5D^2 where D is the new compression

So 0.5d^2/0.5D^2 = Q/2Q

d^2/D^2 = 1/2 which means that D^2 = 2d^2 or D = d(sqrt2)

Therefore, the new compression is roughly 1.414 times that of the old one.

Easiest method for recalling is that KE is proportional to sqrt(d)

To double KE you need to compress the spring sqrt2 times as much as before.

Hope this helps.

PE of spring = stored energy = (1/2)kx^2 = (1.2)mv^2

So kx^2 = mv^2

x^2 = (m/k)v^2

x is proportional to v

To determine the greatest force P that can be applied to the frame, we need to analyze the forces acting on point A. The force P is acting on the frame at an angle of 45 degrees, and we know that the largest force resultant that can act on point A has a magnitude of 5 kN.

We can use vector addition to find the magnitude of the force resultant at point A. We can resolve force P into its x and y components, Px and Py, using trigonometry.

Px = P * cos(45) = P * 1/√2 = P/√2

Py = P * sin(45) = P * 1/√2 = P/√2

The force resultant at point A is the vector sum of Px and Py.

|F_resultant| = √(Px^2 + Py^2) = √((P/√2)^2 + (P/√2)^2) = √(P^2/2 + P^2/2) = √(P^2) = P
