The 16 Days of Activism against gender-based violence is an international campaign that commences on 25 November—the International Day for the Elimination of Violence against Women—and ends on 10 December, Human Rights Day. Originally created by activists, it continues to be coordinated each year by the Center for Women's Global Leadership.The UN supports this civil society-led campaign through the “United Nations Secretary-General’s UNiTE to End Violence against Women Campaign (UNiTE)”. The UNiTE campaign utilizes the colour orange to represent a brighter future, free from violence against women and girls, as a unifying theme running through all of its global activities.Orange the WorldThe involvement of all stakeholders in the mobilization against violence against women, especially in the current context of the COVID pandemic, is essential. This year, the theme set by the Secretary General’s UNiTE campaign was Orange the World: Fund, Respond, Prevent, Collect, with a focus on gender-based violence (GBV) in the context of COVID-19.Our office worked alongside and supported the media to promote campaigns, including on social networks, and awareness-raising sessions for the general public or target groups. The objective was to promote behavioural change by emphasizing positive masculinities and promoting gender equality norms in the context of the COVID-19 pandemic.Due to the lockdowns, services wer forced to define new working modalities to meet the specific needs and expectations of survivors, victims, and people at risk of gender-based violence. UN Human Rights worked with national and local actors to support victims and provide essential services, including the criminal justice system.Finally, the COVID pandemic has highlighted the need for GBV development programmes to respond to the real and expressed needs of women and girls, which is possible through data collection and flexible funding that prioritizes GBV prevention in the COVID-19 budgetary stimulus packages for women’s organizations.

As the elevator moves upward, the cables are under 1,960 N of tension.

The given parameters are,

The mass of the elevator (m) = 200 kg

According to Newton's Second Law of Motion, an object's force is directly inversely proportional to its mass times its acceleration.

The tension in the cables as the elevator travel upwards is calculated by applying the 2nd law of Newton,

T = ma +mg

where a is the acceleration of the elevator and g is the acceleration due to gravity,

At constant velocity, acceleration is zero. (a =0)

T = m(0) +mg

T = mg

T = 200*9.8

T = 1,960 N

Thus, As the elevator moves upward, the cables are under 1,960 N of tension.

Answer:

20 meters

Explanation:

The initial velocity of the ball can be determined using the equation for kinetic energy:

K = (1/2)mv^2

100 J = (1/2) * 0.5 kg * v^2

So, v^2 = 200 J / 0.5 kg = 400 m^2/s^2

The velocity can be determined from the square root:

v = sqrt(400 m^2/s^2) = 20 m/s

Now we can use the velocity to determine the maximum height. The maximum height is reached when the velocity is zero, so we can use the formula for vertical motion under constant acceleration to find the time when this occurs:

v = v0 - gt

0 = 20 m/s - 10 m/s^2 * t

t = 2 s

We can use this time to find the maximum height:

h = v0 * t - (1/2)gt^2

h = 20 m/s * 2 s - (1/2) * 10 m/s^2 * 2 s^2

h = 40 m - 20 m

h = 20 m

So, the maximum height reached by the ball is 20 meters.

V = 3 x 2 + 5 gives the potential of the electric field created by a point charge at any point (x, y, z), where x and y are measured in meters and V is measured in volts. At (2, 1, 0), the electric field has a strength of +12 Vm-1. Here the correct answer is option C.

The electric field E at any point in space is given by the negative gradient of the potential V at that point. That is,

E = -∇V

where ∇ is the gradient operator.

In this case, the potential is given by V = 3x^2 + 5, so the gradient of V is

∇V = ( ∂V/∂x, ∂V/∂y, ∂V/∂z )

= ( 6x, 0, 0 )

Evaluating this at the point (-2, 1, 0) gives

E = (6x, 0, 0)

= (-12, 0, 0)

The magnitude of the electric field intensity is given by

|E| = √(Ex^2 + Ey^2 + Ez^2)

= √((-12)^2 + 0^2 + 0^2)

These photons are emitted by this devices at rate 73.2 x 10¹⁴

Photons can be absorbed or emitted from atoms if the electrons in the atom transition from a state expressed in quantum numbers. The movement of electrons from a lower quantum state to a higher quantum state requires photons.

To determine the rate of the emitted photon, find the energy of each photon first.

Use formula:

E = hc/λ

h is Planck's constant and c is the speed of light.

h = (6.628) (10⁻³⁴) Js

c = (2.998) (10⁸) m/s

So,

E = hc/λ

= (6.626 × 10⁻³⁴)  (2.9 × 10⁸) / (632.8 x 10⁻⁹)

= 3.14 x 10⁻¹⁹ J

Hence the energy emitted = 2.3 x 10⁻³

A force of 30 N to the right is applied to an object. An opposite force of 20 N to the left is applied to the same object. What is the net force applied to the object?

A. 10 N to the left

B. 50 N to the right

C. 50 N to the left

D. 10 N to the right

Add the two vectors:  30R = +30, 20L = -20 Sum = +10 or 10R

The force acting on two bodies will be the same if they have same mass and same acceleration. But the acceleration is dependant on the net force of the body and thus option C is correct. The net force of the body is 10 N to the right.

Force is an external agent or factor which change an object from its state of rest or motion. The force to be applied depends on the mass and acceleration of the body by the equation F = ma.

Acceleration of a moving body is dependant on the direction and thus the direction of force and net force. Thus the two objects having the same mass and same force f applied to them, the acceleration may not be the same. Thus option C is correct.

The two force acting on a body in opposite direction will cancel each other in magnitude. Thus 20N of force to the right will be cancel by 20 N to the left. Remaining 10N will be there to the right direction. Hence, option D is correct.

Answer:

Explanation:

The addition of two simple harmonic motions will produce a result that is also simple harmonic if the two simple harmonic motions have the same frequency and phase.

When two simple harmonic movements attain their maximum or lowest values at the same moment, they are said to be in phase. If the amplitudes of two simple harmonic movements have the same frequency and are in phase, the amplitude of the resulting motion may be calculated. This indicates that the combined system's motion will still oscillate at the same frequency as the separate movements and will be sinusoidal in form, as is the distinguishing feature of simple harmonic motion. As a result, adding two simple harmonic movements with the same frequency and phase results in a consequent motion that is likewise simple harmonic.

The mass of NaNO3 needed to make 4.50 L of a 1.50 M NaNO3 solution is 574 g.

To calculate the mass of NaNO3 needed, we first need to determine the number of moles of NaNO3 required. We can use the formula: moles of solute = Molarity × liters of solution. Given that the molarity is 1.50 M and the volume is 4.50 L, we can calculate the moles of NaNO3 required. To convert moles to grams, we use the molar mass of NaNO3, which is 85.00 g/mol. Multiplying the moles of NaNO3 by its molar mass gives us the mass of NaNO3 needed, which is 574 g.

So her speed at the bottom of the hill is approximately 10.0 m/s.To find the girl's speed at the bottom of the hill, we can use the principle of conservation of mechanical energy.

At the top of the hill, the total mechanical energy is equal to the sum of kinetic energy and potential energy:

E_top = E_kinetic + E_potential

The kinetic energy of the girl and her bicycle is given by:

E_kinetic = (1/2) * m * v_top^2

where m is the total mass (40 kg) and v_top is the speed at the top of the hill (5.0 m/s).

The potential energy at the top of the hill is:

E_potential = m * g * h

where g is the acceleration due to gravity (approximately 9.8 m/s^2) and h is the height of the hill (10 m).

Since there is no other energy input or output besides the force of friction, the total mechanical energy is conserved, and we can equate the mechanical energy at the top to the mechanical energy at the bottom of the hill:

E_top = E_bottom

(1/2) * m * v_top^2 + m * g * h = (1/2) * m * v_bottom^2

We need to solve for v_bottom, which is the speed at the bottom of the hill.

Now, we can rearrange the equation and solve for v_bottom:

(1/2) * m * v_top^2 + m * g * h = (1/2) * m * v_bottom^2

Substituting the given values:

(1/2) * 40 kg * (5.0 m/s)^2 + 40 kg * 9.8 m/s^2 * 10 m = (1/2) * 40 kg * v_bottom^2

100 J + 3920 J = 20 J + 20 J + v_bottom^2

3920 J + 100 J = 40 kg * v_bottom^2

4020 J = 40 kg * v_bottom^2

Dividing both sides by 40 kg:

v_bottom^2 = 4020 J / 40 kg

v_bottom^2 = 100.5 m^2/s^2

Taking the square root of both sides:

v_bottom = √(100.5 m^2/s^2)

v_bottom ≈ 10.0 m/s

Therefore, her speed at the bottom of the hill is approximately 10.0 m/s.

The indestructible bullet, 2.00 cm long, will penetrate straight through the 10 cm thick board with its initial speed.

When an indestructible bullet is fired straight through a board, its length and the thickness of the board are relevant factors in determining whether the bullet will pass through or get lodged inside. In this case, the bullet is 2.00 cm long, while the board is 10 cm thick.

Since the bullet is described as indestructible, it implies that the bullet will not deform or break upon impact with the board. As a result, the bullet will continue moving through the board, provided its length is smaller than the thickness of the board.

With the given information, we can conclude that the indestructible bullet, being 2.00 cm long, will penetrate straight through the 10 cm thick board. The initial speed of the bullet does not affect this outcome, as long as it meets the condition of being smaller in length than the board's thickness.

It is important to note that this explanation assumes ideal conditions, where the bullet and board are perfectly aligned, and there are no external factors affecting the motion of the bullet. In practical scenarios, various factors such as angle, velocity, and material properties can influence the bullet's behavior upon impact.

Answer:

a. No. The overall loudness is not proportional to the number of speakers.

b. No, it will not sound 4 times louder.

Explanation:

a. Loudness is the quality of how loud or soft the sound is. Since loudness is proportional to intensity and intensity proportional to the amplitude of the sound, the overall loudness of the sound would not be proportional to the number of speakers.

Since the sound from each speakers adds by superposition, their phases might be different but their amplitudes the same. So, the resultant wave from the four speakers has the same amplitude as the wave from one speaker. And, since loudness is proportional to amplitude, the loudness of the resultant wave is equal to the loudness of each individual speaker.

So, the loudness is not proportional to the number of speakers.

b. No, it will not sound 4 times louder.

This is because loudness is a function of amplitude.

Since the devices are identical and playing the same sound, their amplitudes are the same. They will thus add by superposition to generate a resultant wave which has an amplitude the same as each individual wave.

Since the amplitude of the resultant wave is the same and not an addition of each individual amplitude, the resultant wave does not sound 4 times louder.
