The change in the momentum of the bus is 10600 kg-m/s, if bus of 1600 kg crashes with a SUV of 600 kg.

The mass of the bus, m₁ = 1600 kg

The mass of the SUV, m₂ = 600 kg

Initial velocity of the bus, v₁ = 10 m/s

initial velocity of the SUV, v₂ = 0 (at rest)

Velocity of the bus after collision, v₃ = 3 m/s

Velocity of the SUV after collision, v₄ = 1 m/s

The change in momentum(Δp) is given by,

Δp = (m₁v₁ + m₂v₂) - (m₁v₃ + m₂v₄)

Δp = (1600 × 10 + 600 × 0) - (1600 × 3 + 600 × 1)

Δp = 16000 - 5400

If you stand on a bathroom scale and it reads 498 N, the value of the upward support force, in N, acting on you is also 498 N.

If the bathroom scale reads 498 N, it means that the scale is measuring the force exerted on it by your weight. Therefore, the value of the upward support force acting on you is also 498 N. This is because the scale is designed to balance out the downward force of your weight with an equal and opposite upward force. To find the value of the upward support force acting on you, we need to understand the concept of weight and the forces acting on an object.

1. Weight: Weight is the force exerted on an object due to gravity. It is the product of an object's mass and the acceleration due to gravity.

2. Mass: Mass is a measure of the amount of matter in an object. It is a scalar quantity and is usually measured in kilograms (kg).

3. Acceleration due to gravity: On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (m/s²).

4. Upward support force: When you stand on a bathroom scale, it measures the force exerted on it by your weight. The scale displays the magnitude of this force.

The weight of an object on the surface of a planet is given by

\(F = G\dfrac{mM}{r^2}\\\\\)

where F is the force or weight in Newtons

G is the universal gravitational constant

m is the mass of the object

M is the mass of the planet

r is the radius of the planet

Mars has a smaller radius and smaller mass than the Earth.

The gravitational force on Mars is approximately 38% of the gravitational force on Earth because of the smaller mass and smaller radius

The luminosity of a star is a measure of its brightness, specifically, the total amount of energy it emits per unit time.

It is often described in terms of the star's apparent magnitude, which is how bright it appears to us on Earth, or its absolute magnitude, which is how bright it would appear if it were placed at a standard distance of 10 parsecs from Earth. Luminosity is an important property of stars, as it is related to their size, mass, and temperature, and can be used to classify them into different spectral classes.

These classes, which range from O to M, are based on the star's surface temperature and the elements present in its atmosphere. For example, hotter stars with a blue-white color are classified as O or B, while cooler, reddish stars are classified as K or M.

The unit tangent vector T(t) for the curve defined by r(t) = (e², 2t, e) at t = 2 is \(\[T(2) = \left(\frac{e^2}{\sqrt{e^4 + 16 + e^2}}, 4, e\right)\]\). The unit normal vector N(t) for the curve at \(\[N(2) = \left(\frac{-2e^2}{\sqrt{4e^4 + 1}}, 1, 0\right)\]\).

The normal acceleration ar at \(\[ar(2) = \frac{\sqrt{4e^4 + 1}}{\sqrt{e^4 + 16 + e^2}}\]\). The tangential acceleration at t = 2 is aT(2) = 0 since the curve is defined as a straight line and has no curvature.

To find the unit tangent vector T(t), we take the derivative of the position vector r(t) with respect to t and normalize it by dividing by its magnitude. The derivative of \(\[T(t) = \frac{(e^2, 4, e)}{\sqrt{e^4 + 16 + e^2}}\]\).

To find the unit normal vector N(t), we differentiate T(t) with respect to t and normalize the resulting vector. The derivative of T(t) is (0, 0, 0), which means the curve is a straight line. Therefore, N(t) is constant and given by \(\[N(t) = \frac{(-2e^2, 1, 0)}{\sqrt{4e^4 + 1}}\]\).

The normal acceleration ar at t = 2 is the magnitude of the derivative of T(t) with respect to t, which simplifies to \(\[\frac{\sqrt{4e^4 + 1}}{\sqrt{e^4 + 16 + e^2}}\]\).

Since the curve is a straight line, there is no change in the direction of the velocity vector, and therefore, the tangential acceleration aT is zero.

Explanation:

As because Speed= distance/time taken

so time taken= 3.71

Answer:

Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.

Total distance taken by the ball until it reaches the ground is   41.2 m. The closest correct option is D.

h = (vi²)/2g

where h = height reached by the ball

vi = initial velocity

g = acceleration due to gravity

The maximum height reached by the ball, using the same equation

vi = 20 m/s and g = 9.81 m/s²

h = (20²)/2(9.81) = 20.3 m

The ball travels more than twice as far as it can go before touching the ground.

Total distance = 2h = 2(20.3) = 40.6 m

Answer:

The length of the incline is 3.504 meters.

Explanation:

Let suppose that Julietta's ball decelerates uniformly, then we determine the length of the incline is determined by the following equation of motion:

\(\Delta s = v_{o}\cdot t +\frac{1}{2}\cdot a \cdot t^{2}\) (Eq. 1)

Where:

\(\Delta s\) - Length of the incline, measured in meters.

\(v_{o}\) - Initial speed of the ball, measured in meters per second.

\(a\) - Aceleration of the ball, measured in meters per square second.

\(t\) - Time, measured in second.

If we know that \(v_{o} = 2.95\,\frac{m}{s}\), \(t = 1.54\,s\) and \(a = -0.876\,\frac{m}{s^{2}}\), then the length of the incline is:

\(\Delta s = \left(2.95\,\frac{m}{s} \right)\cdot (1.54\,s)+\frac{1}{2}\cdot \left(-0.876\,\frac{m}{s^{2}} \right) \cdot (1.54\,s)^{2}\)

\(\Delta s = 3.504\,m\)

The length of the incline is 3.504 meters.

The electric potential at a point due to the charged sphere will be equal to that due to the point charge if the radial distance of the point is greater than or equal to the radius of the charged sphere since the amounts of the charges are identical.

One of the essential components of matter is a point charge, such as an electron. Furthermore, circular charge distributions (such as those seen on a metal sphere; see image below) produce external electric fields in the same way that point charges do. Thus, a scenario that requires our attention is the electric potential caused by a point charge. It may be demonstrated that the electric potential V of a point charge is equal to the work required to transfer a test charge q from a great distance away to a distance of r from it using calculus and observing the relationship between work and potential (W=-qV).

No, the sun cannot explain global warming. Global warming is a phenomenon in which the temperature of the Earth's surface and atmosphere is rising continuously due to human activities such as deforestation, burning of fossil fuels, and industrialization.

This increase in temperature cannot be explained only by an increase in solar radiation.There are several factors which contribute to global warming, including greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the Earth's atmosphere, which causes the planet's temperature to rise. The sun's radiation does contribute to global warming, but it is not the main cause.

i) To calculate the increase in solar radiation that would cause the Earth to warm up by 1 K, we can use the following formula:ΔS = ΔT / αWhere ΔS is the increase in solar constant, ΔT is the increase in temperature, and α is the Earth's albedo (reflectivity).α = 0.30 is the standard value used for the Earth's albedo.ΔS = ΔT / αΔS = 1 K / 0.30ΔS = 3.33 W/m2So, to explain the increase in temperature of 1 K over the last hundred years, the solar constant would need to increase by 3.33 W/m2.

ii) The observed fluctuation of the solar constant over the past 400 years has been around 0.1% to 0.2%. This is much smaller than the 3.33 W/m2 required to explain the increase in temperature of 1 K over the last hundred years. Therefore, it is unlikely that the sun is the main cause of global warming.

The sun cannot explain global warming. While the sun's radiation does contribute to global warming, it is not the main cause. The main cause of global warming is human activities, particularly the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.

A girl rides her cycle round a circular track of diameter 60 m. The track is banked at 15° to the horizontal. The coefficient of friction between the track and the tyres of the cycle is 0.25. Modelling the girl and her cycle as a particle of mass 60 kg moving in a horizontal circle, the minimum speed at which she can travel without slipping is 13.64 m/s.

To find the minimum speed at which the girl can travel without slipping, we need to consider the forces acting on her and her cycle as they move in a circular track.

The forces acting on the girl and her cycle are the gravitational force (mg), the normal force (N), and the frictional force (f). The frictional force provides the centripetal force necessary to keep the girl moving in a circular path.

The normal force can be resolved into two components: the vertical component (N⊥) and the horizontal component (N∥). The vertical component balances the gravitational force, while the horizontal component provides the centripetal force.

Mass of the girl and cycle (m) = 60 kg

Diameter of the circular track (d) = 60 m

Bank angle (θ) = 15 degrees

Coefficient of friction (μ) = 0.25

Find the normal force components:

N⊥ = mg cos(θ)

N∥ = mg sin(θ)

The frictional force:

f = μN⊥

The frictional force (f) provides the centripetal force required for circular motion:

f = m(v² / r)

Here, v is the velocity and r is the radius of the circular track. The radius is:

r = d / 2

Combining the equations, we have:

μN⊥ = m(v² / r)

Substituting the values we have:

μmg cos(θ) = m(v² / (d / 2))

v² = (μmg cos(θ) / m) * (d / 2)

v² = (μg cos(θ)) * (d / 2)

v = √((μg cos(θ)) * (d / 2))

v = √((0.25 * 9.8 * cos(15)) * (60 / 2))

v ≈ 13.64 m/s

Therefore, the minimum speed at which the girl can travel without slipping is approximately 13.64 m/s.
