The velocity after 2 seconds is 26 m/s. It takes 11.50 seconds to reach a velocity of 40m/s.

Given the equation s(t) = 6t + 5t²

Let's find the velocity after 2 seconds.

(a) Velocity = (ds)/(dt)

Differentiating s(t) with respect to t, we get; ds(t) / dt = 6 + 10t

At t = 2,ds(t) / dt = 6 + 10t = 6 + 10(2) = 26m/s

Therefore, the velocity after 2 seconds is 26 m/s.

(b) We are to find how long it takes for the velocity to reach 40m/s. We know that the initial velocity of the ball, u = 6m/s. Acceleration = gsinθ = 9.81 x sin (angle of inclination) = 9.81 x 0.3 = 2.943 m/s²From the first equation of motion, v = u + at

We know v = 40m/s, u = 6m/s, a = 2.943m/s² and t is what we are to find, hence the equation becomes;40 = 6 + 2.943(t)t = (40 - 6) / 2.943t = 11.50s

Therefore, it takes 11.50 seconds to reach a velocity of 40m/s.

A little bit more than 64 N of force is required to move the box at a constant speed.

When the rate at which such an object is changing its position is constant in magnitude and direction, the object is said to have constant velocity. To put it another way, for an object to maintain constant velocity, both its movement and its speed must be constant across time.

The formula yields the coefficient of sliding friction;

μ= F/R

Where;

F = frictional force

μ = coefficient of sliding friction

R = Normal reaction

It is important to remember that in order to move a body, a force must be applied that is larger than the frictional force that exists between the body and the surface. As a result, a force of slightly more than 64 N is required to move the box at a constant speed.

The angular velocity of the propeller in radians per second is 125.66 rad/s.

To convert revolutions per minute to radians per second, we need to multiply by 2π/60. Therefore:

Angular velocity = (1200 rev/min) x (2π/60) = 125.66 rad/s

So the angular velocity of the propeller is 125.66 rad/s.

The angular velocity is a measure of the rate of rotation of an object. In this case, the propeller is rotating at a high speed of 1200 revolutions per minute, which corresponds to an angular velocity of 125.66 rad/s. This high angular velocity is necessary to provide the necessary thrust for the fighter plane to fly at high speeds and perform various maneuvers.

The force F1 is equal and opposite to the downward force thus, F1 is equal to 60 N. The force F2 is inclined to 30 ° from leftward force and it is equal to 38.97 N in magnitude.

Force is an external agent acting on a body to deform it or to change its state of motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction.

If two forces acting on a body from the same directions, then the net force will be the sum of these two forces. If they are acting from opposite directions, they will cancel each other in magnitude.

The force F1 is equal and opposite to the force acting downward. Thus its magnitude is 60 N. The force F2 is inclined to 30 ° from horizontal direction.

F2 = 45 cos 30 = 38.9 N.

Cecil can just barely clear a pet gate that is 0.81-m tall when she launches herself at a 45° angle from a distance of 1.5-m from the base of the gate. Her launch speed is 4.4 m/s. She was in the air for 0.193 s. She lands 0.556 m behind the gate.

To determine Cecil's launch speed, we can use the kinematic equations for projectile motion. Let's break down the problem into three parts:
(a) Launch speed:
Given that Cecil can barely clear the pet gate, we can assume that her vertical displacement (Δy) is equal to the height of the gate, which is 0.81 m. The launch angle (θ) is 45°. We can use the following equation to calculate her launch speed (v):
Δy = (\(v^2\) * sin²θ) / (2 * g)
Where g is the acceleration due to gravity, approximately \(9.8 m/s^2.\)
Plugging in the values:
0.81 m = (v^2 * sin² 45°)) / (2 * \(9.8 m/s^2.\))
Simplifying the equation, we get:
v^2 = (0.81 m * 2 * \(9.8 m/s^2.\)) / sin²(45°)
Taking the square root of both sides, we find:
v = sqrt((0.81 m * 2 * \(9.8 m/s^2.\)) / sin²(45°))
Calculating the value, we find:
v ≈ 4.4 m/s
Therefore, Cecil's launch speed is approximately 4.4 m/s.
(b) Time in the air:
To determine how long Cecil is in the air, we can use the vertical component of her motion. We can use the following equation:
Δy = v0y * t - (1/2) * g * t²
Where Δy is the vertical displacement, v0y is the initial vertical velocity (which can be found using the launch speed and launch angle), t is the time in the air, and g is the acceleration due to gravity.
Given that the initial vertical velocity (v0y) is equal to v * sinθ, we can rearrange the equation to solve for t:
0.81 m = (v * sinθ) * t - (1/2) * g * t²
Plugging in the values:
0.81 m = (4.4 m/s * sin(45°)) * t - (1/2) * \(9.8 m/s^2.\) * t²
Simplifying the equation, we get a quadratic equation:
(1/2) * \(9.8 m/s^2.\)* t² - (4.4 m/s * sin(45°)) * t + 0.81 m = 0
Solving this quadratic equation, we find two possible solutions for t:
t ≈ 0.193 s or t ≈ 0.046 s
Since Cecil cannot be in the air for a negative amount of time, the valid solution is:
t ≈ 0.193 s
Therefore, Cecil is in the air for approximately 0.193 seconds.
(c) Distance behind the gate:
To determine how far behind the gate Cecil lands, we can use the horizontal component of her motion. We can use the following equation:
Δx = v0x * t
Where Δx is the horizontal displacement, v0x is the initial horizontal velocity (which can be found using the launch speed and launch angle), and t is the time in the air.
Given that the initial horizontal velocity (v0x) is equal to v * cosθ, we can plug in the values to calculate Δx:
Δx = (4.4 m/s * cos(45°)) * 0.193 s
Simplifying the equation, we find:
Δx ≈ 0.556 m
Therefore, Cecil lands approximately 0.556 meters behind the gate.

The luminosity of star A will be much higher than that of star B because the luminosity is directly proportional to the square of the radius.

Since the radius of star A is double that of star B, the luminosity of star A will be four times that of star B, meaning it will be much brighter. This is because the surface area of star A is four times larger than that of star B, which means it has more space to radiate energy.

This is why stars with larger radii tend to be brighter than those with smaller radii, even if they have similar temperatures.

13.The color with the longest wavelength is option A. Red.

14.The sky appears blue due to option D. Scattering of light.

Red light has a longer wavelength compared to yellow and blue light.The color that has the longest wavelength is red. The color of the sky appears blue due to scattering of light. The distance between one peak and the next in a series of waves, particularly electromagnetic waves traveling through space or along a wire is referred to as wavelength.

The wavelength of light, for example, determines its color. Red light has the longest wavelength, followed by orange, yellow, green, blue, and purple, with violet light having the shortest wavelength. When light is reflected off a surface or passes through a medium, it can be deflected in various directions, a phenomenon known as scattering of light.

The Earth's atmosphere scatters sunlight in all directions, but the shorter blue wavelengths are scattered more than the longer wavelengths. As a result, we perceive the sky as blue during the day.  The light becomes scattered when it interacts with particles in the atmosphere, causing the sky to appear blue during the day and red during sunset or sunrise. The scattering of light is the process that causes the sky to appear blue.

latent heat also called the heat of vaporization is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure.

(a) To find the magnification, we first need to determine the image distance (q). We can use the lens formula:
1/f = 1/p + 1/q

where f is the focal length (0.140 m), p is the object distance (0.240 m), and q is the image distance. Rearranging the formula to solve for q:
1/q = 1/f - 1/p
1/q = 1/0.140 - 1/0.240
1/q = 0.00714
q = 1/0.00714 ≈ 0.280 m
Now, we can find the magnification (M) using the formula:
M = -q/p
M = -0.280/0.240
M = -1.17
The magnification is -1.17.
(b) To find the image height (h'), we can use the magnification formula:
h' = M × h
where h is the object height (0.064 m). Plugging in the values:
h' = -1.17 × 0.064
h' ≈ -0.075 m
The image height is approximately -0.075 meters. The negative sign indicates that the image is inverted.

When an electron is accelerated from rest across the gap of a capacitor, it means that it moves from one plate to another. In this case, the two plates are charged with -q and q, respectively.

The electron emerges with a constant velocity of v through a hole in the top plate. The acceleration of the electron can be calculated using the equation: acceleration = change in velocity/time.

The electron is a subatomic particle (denoted by the symbol e or β−) whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family and are generally thought to be elementary particles because they have no known components or substructure.
