The slope of the graph of the equation at the point (20, 2) is 1/8.

To find the slope of the graph of the equation at the given point (20, 2), we need to find the derivative of the equation with respect to x and evaluate it at x = 20. Let's differentiate the equation implicitly:

xy - 9y^2 = 4

To differentiate implicitly, we treat y as a function of x and apply the chain rule. Differentiating both sides of the equation with respect to x:

1 * y + x * dy/dx - 9 * 2y * dy/dx = 0

Simplifying this equation:

y + x * dy/dx - 18y * dy/dx = 0

Grouping the terms with dy/dx:

dy/dx * (x - 18y) = -y

Now, let's solve for dy/dx by dividing both sides by (x - 18y):

dy/dx = -y / (x - 18y)

Substituting the given point (20, 2) into the equation:

dy/dx = -2 / (20 - 18(2))

         = -2 / (20 - 36)

         = -2 / (-16)

The velocity when function p(t)=11 is 8 .

According to the question

The position of a car at time t  represented by function :

\(p(t)=t^{2} +2t-4\)

Now,

When  function p(t) = 11 , t will be

\(p(t)=t^{2} +2t-4\)

11 = t²+2t-4

0 = t² + 2t - 15

or

t² +2t-15 = 0

t² +(5-3)t-15 = 0

t² +5t-3t-15 = 0

t(t+5)-3(t+5) = 0

(t-3)(t+5) = 0  

t = 3 , -5  

as t cannot be -ve as given ( t≥0)

so,

t = 3

Now,

the velocity when p(t)=11

As we know velocity = \(\frac{position}{time}\)

therefore to get the value of velocity from  function p(t)

we have to differentiate the function with respect to time

\(\frac{d(p(t))}{dt} =\frac{d}{dt} (t^{2} +2t-4)\)

v(t) = 2t + 2  

where v(t) = velocity at that time

as t = 3 for  p(t)=11  

so ,

v(t) = 2t + 2  

v(t) = 2*3 + 2  

v(t) = 8

Hence, the velocity when function p(t)=11 is 8 .

The efficiency of a bulb can be calculated as the ratio of the useful energy output (in this case, the light energy) to the total energy input. In this scenario, the useful energy output is 500 J - 350 J = 150 J, and the total energy input is 500 J. So, the efficiency can be calculated as:

Efficiency = (useful energy output) / (total energy input) = (150 J) / (500 J) = 0.3 or 30%.

The illuminance at screen B is one-fourth (25%) of the illuminance at screen A.

The illuminance at a screen is directly proportional to the inverse square of the distance from a point source of light. In this scenario, the distance between the point source and screen A is half that of the distance between the point source and screen B.

According to the inverse square law, the illuminance at screen A will be four times greater than the illuminance at screen B. This is because when the distance is halved, the illuminance increases by a factor of four (2^2).

To explain further, if we assume the illuminance at screen A is X, then the illuminance at screen B would be X/4. The factor of 1/4 arises from the inverse square relationship between distance and illuminance.

Therefore, the illuminance at screen B is one-fourth (25%) of the illuminance at screen A. In other words, screen B receives only 25% of the light intensity compared to screen A.

Therefore, the average speed of the hockey player is 8.43 m/s

The hockey player is moving at a speed of 9.5 m/s.

Given: Distance (x) covered by the ball = 180 m, maximum height (y) reached by the ball = 21.3 m The trajectory followed by the ball can be modelled using the equations of motion. The initial velocity of the ball is 31.63 m/s.

The equations of motion relate the displacement, velocity, time and acceleration of the moving body. The general equation of motion for vertical motion under gravity is: y = u sinθt - 1/2 gt²where y is the vertical displacement, u is the initial velocity, θ is the angle of projection, g is the acceleration due to gravity and t is the time taken to reach the maximum height.

The maximum height is given by: (u y = 0)t = u sinθ/g Solving for t, we have: t = (u sinθ)/g Therefore, the equation of motion becomes: y = (u²sin²θ)/ 2 g Putting the given values in the above equation:21.3 = (u² sin² 45)/ (2 x 9.8) => u = 31.63 m/s Therefore, the initial velocity of the ball is 31.63 m/s.

When end B of the rope is pulled down, the rope around the pulley moves in the same direction with the same speed.

The Zenith angle at 45 degrees North during the Spring Equinox is 45 degrees.

The Zenith angle is measured as the angle between the vertical line (directly overhead) and the line connecting the observer to the Sun. During the Spring Equinox, when the Sun is directly above the Equator, the Zenith angle at any latitude is equal to the latitude itself.

To calculate the Zenith angle, Solar elevation angle, and beam spreading at a site located at 45 degrees North on the Autumnal equinox (September 22nd), additional information is needed, such as the time of day and the observer's exact location (longitude). These factors affect the position of the Sun in the sky. The Zenith angle is the angle between the vertical line and the line connecting the observer to the Sun. The Solar elevation angle is the complement of the Zenith angle (90 degrees minus the Zenith angle). Beam spreading refers to the divergence of the solar beam as it travels through the atmosphere, which is influenced by factors such as atmospheric conditions and the Sun's position.

The latitude at which daylight hours have the least variability is the Equator (0 degrees latitude). At the Equator, the length of daylight hours remains relatively constant throughout the year, with minimal variation. In contrast, as you move farther away from the Equator towards the poles, the variability in daylight hours becomes more pronounced, with significant changes between the seasons.

False. The spread of the solar beam, known as beam spreading, is actually greater at higher solar angles (closer to 90 degrees) compared to lower solar angles (closer to 0 degrees). At higher solar angles, the solar beam covers a larger area due to the greater incidence angle, resulting in a larger spread of solar radiation. As the solar angle decreases and approaches 0 degrees, the solar beam becomes more concentrated and focused on a smaller area, leading to a higher intensity of solar radiation at that point.
