Explanation:

The height of the flare relative to ground is 202.3 m. This is the sum of height reached by the flare and the 3 m platform above the ground.

The maximum height reached by the flare is determined from the principle of conservation of energy as shown below;

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

h = (v²)/(2g)

where;

h = (62.5)²/(2 x 9.8)

h = 199.3 m

H = 199.3 + 3

H = 202.3 m

Thus, the height of the flare relative to ground is 202.3 m. This is the sum of height reached by the flare and the 3 m platform above the ground.

The given statement ''Bandura found that children who witnessed aggressive behavior being punished were far more likely to be aggressive than children who did not'' is false because

Bandura found that children who witnessed aggressive behavior being rewarded or not punished were more likely to be aggressive than children who did not witness such behavior. This is known as the social learning theory.

In Bandura's famous Bobo doll experiment, children were divided into three groups one group witnessed an adult model behaving aggressively towards a Bobo doll, another group witnessed a non-aggressive adult model playing with other toys, and the third group did not witness any adult model.

The results showed that children who witnessed the aggressive behavior being punished were less likely to imitate the behavior, while those who witnessed the aggressive behavior being rewarded or not punished were more likely to imitate the behavior. This suggests that children learn through observation and modeling, and that consequences play an important role in shaping behavior.

Answer:

3.16 m/s

Explanation:

Use the formula

[tex]k = \frac{m {v}^{2} }{2} \\ v = \sqrt{ \frac{2k}{m} } \\ v = \sqrt{ \frac{2(200)}{40} } \\ v = 3.16 \frac{m}{s} [/tex]

Given the value of the mass of each boxes, the work done in lifting the boxes to the given height is 1.6 × 10⁵J.

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

W = F × d

Where F is force applied or Weight and d is distance

Also Force = Weight = mass × acceleration due to gravity.

Since gravity is acting on the boxes as it been lift

W = Weight × height from ground level

W = mg × d

Where m is mass of the boxes, g is accelration due to gravity( g = 9.8m/s² ) and d is distance from ground level.

Given the data in the question;

To determine the work done, we substitute our values into the expression above.

W = mg × d

W = 2722.05kg × 9.8m/s² × 6.0m

W = 160056.5kgm²/s²

W = 160056.5J

W = 1.6 × 10⁵J

Therefore,  Given the value of the mass of each boxes, the work done in lifting the boxes to the given height is 1.6 × 10⁵J.

Answer:

√35 square units

Explanation:

Area of square = 35square units

Formula of area of square is a =s*s where a is area and s is side

So,

s*s = 35

s^2= 35

s = √35

tell me if this is the answer u r looking for

The formula for the area of square is (side)² and to find the dimension or side length of the square with an area of 35 square units is √35 units.

Area is defined as the total space which is covered by a flat (2 dimensional) surface or shape of an object. The space that is covered up on the paper is called its Area. The area of a shape is the number of unit squares that is required to completely cover it. Therefore, it is measured in square units such as m² or cm².

Answer:

See below

Explanation:

Since it is non-uniform acceleration ( it varies with time as given)

The integral of acceleration is velocity

so integrate between 0 and three   15 m/s^2 t

    =   1/2  ( 15 t^2 )   + k      between 0 and 3    ( k is a constant we will ignore)

            = 67.5   - 0     =   67.5 m/s   velocity

the integral of velocity is displacement

 1/2 (15t^2 )   integrated becomes     1/6 15 t^3    from 0 to 3  ( ignoring a constant again)

                                      1/6 * 15 * (3^3 ) = 67.5 meters displacement

Explanation:

Refraction, reflection, and total internal reflection are distinct optical phenomena. They involve the bending, bouncing, and complete reflection of light, respectively. These phenomena have practical applications and contribute to our understanding of light behavior and optical devices.

Refraction, reflection, and total internal reflection are fundamental phenomena associated with the behavior of light when it interacts with different mediums or interfaces. Let's explore each of these concepts and understand their distinctions:

1. Refraction:

Refraction refers to the bending of light as it passes from one medium to another with a different optical density. When light encounters a change in medium, its speed and direction change, causing the light ray to deviate. This deviation occurs because light travels at different speeds in different materials. The amount of bending depends on the angle of incidence and the refractive indices of the two mediums involved. Snell's law governs the mathematical relationship between the angles of incidence and refraction. Refraction is responsible for various optical phenomena, such as the bending of light in lenses and the dispersion of white light into its constituent colors in a prism.

2. Reflection:

Reflection occurs when light encounters a boundary between two mediums and bounces back into the same medium from which it originated. The angle of incidence is equal to the angle of reflection, according to the law of reflection. Reflection plays a fundamental role in our ability to see objects, as light rays reflected from surfaces enter our eyes. Mirrors and other reflective surfaces exploit the principle of reflection.

3. Total Internal Reflection:

Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence exceeds a critical angle. In such cases, instead of bending or refracting, the light is completely reflected back into the denser medium. Total internal reflection is responsible for various phenomena, including the shiny appearance of diamonds and the working of optical fibers. It enables light to propagate through the fiber by repeated internal reflections.

In conclusion, refraction, reflection, and total internal reflection are distinct optical phenomena. Refraction involves the bending of light when it transitions between different mediums, reflection refers to the bouncing back of light from a surface, and total internal reflection occurs when light is reflected back into a denser medium at an angle greater than the critical angle. These phenomena have practical applications and contribute to our understanding of light behavior and the functioning of various optical devices.

The density of the cube of wood placed in the tub of water is determined as 700 kg/m³.

The specific gravity of the wood is the fraction of the entire wood volume below water surface.

Height below water surface = 20 cm - 6 cm = 14 cm

S.G = 14 cm/20 cm

S.G = 0.7

The density of the wood is calculated with respect to density of water.

S.G = ( density of wood) / (density of water)

0.7 =  (density of wood) / (1000 kg/m³)

density of wood = 0.7 x 1000 kg/m³

Explanation:

Without the Sun , Earth's land, water, and air would all be frozen. Energy is transferred from the sun to Earth via electromagnetic waves, or radiation

Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection.

The speed most likely representing a gas will be 334 m/sec. A sound wave is produced when a medium begins to vibrate. When an entity vibrates, a pressure wave is formed, which causes sound.

When an object vibrates, a pressure wave is created, which produces sound. The particles in the surrounding medium (air, water, or solid) vibrate as a result of the pressure wave.

The vibrations of the particles move nearby particles, allowing the sound to travel further through the medium.

Hence, the speed most likely representing a gas will be 334 m/sec.
