Answer:

\(2.33\ m/s^2\)

Explanation:

Net Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

Fn = m.a

Where a is the acceleration of the object.  The net force is the sum of the individual vector forces applied to the object.

The m=1500 Kg car has two horizontal forces applied: the forward force of 5000 N that causes the movement and the air resistance force of 1250 N that opposes motion.

The net force is Fn = 5000 N - 1500 N = 3500 N

To find the acceleration, we solve the equation for a:

\(\displaystyle a=\frac{Fn}{m}\)

\(\displaystyle a=\frac{3500}{1500}\)

\(\boxed{a = 2.33\ m/s^2}\)

The car's acceleration is \(a = 2.33\ m/s^2\)

Answer:

Explanation:

The velocity of the runner having a mass of 75 kg will be 9.93 m/s.

The energy of the body by virtue of its motion is called its kinetic energy.

Given is velocity of a runner who has a mass of 75 kg and 3,700 Joules of energy.

The kinetic energy of the body is given by the following formula -

KE = 1/2 mv².

Substituting the values -

3700 = 1/2 x 75 x v²

7400 = 75 x v²

v² = 7400/75

v² = 98.66

v = 9.93 m/s

Therefore, the velocity of the runner having a mass of 75 kg will be 9.93 m/s.

A truck enters a highway driving 60 mph A car enters the highway at the same place 0 nutes later and dives 72 mph in t The car will pass the truck in (Round to the nearest minute) minutes same direction From So the car enters the highway,However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.

To determine how long it will take the car to pass the truck, we can set up an equation based on their relative speeds and distances traveled.

Let's assume that the car passes the truck after time 't' minutes.

In 't' minutes, the truck will have traveled a distance of 60 × (t/60) = t miles.

The car enters the highway 0 minutes later and travels at a speed of 72 mph. Therefore, when the car passes the truck, it will have traveled a distance of 72 × (t/60) = 1.2t miles.

To find when the car passes the truck, we can set up the following equation:

t = 1.2t

Simplifying the equation, we get:

t - 1.2t = 0.2t

0.2t = 0

This equation does not yield a valid solution since it implies that the time required for the car to pass the truck is 0 minutes. However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.

a. The hydroxide concentration required to initiate precipitation is 2.50 x 10⁻² M.

b. To lower the Al³⁺ concentration in the solution to 2.00 x 10⁻⁷ M, we can use the common ion effect by adding excess OH⁻ ions.

(A). To initiate the precipitation of Al³⁺ from a 2.50 x 10⁻² M solution of Al(SO₄)₃, the solubility product constant (Ksp) of aluminium hydroxide (Al(OH)₃) is determined. The balanced equation for the dissociation of Al₂(SO₄)₃ is:

Al₂(SO₄)₃(s) ⇌ 2Al³⁺(aq) + 3SO₄²⁻(aq)

The Ksp expression for aluminium hydroxide is Ksp = [Al³⁺][OH⁻]³.

At the point of precipitation, the concentration of Al³⁺ will be equal to the concentration of OH- ions.

Therefore, [Al³⁺] = [OH⁻].

Given [Al³⁺] = 2.50 x 10⁻² M,

So,the hydroxide concentration required to initiate precipitation is also 2.50 x 10⁻² M.

(B). To lower the Al³⁺ concentration in the solution to 2.00 x 10⁻⁷ M, we can use the common ion effect by adding excess OH⁻ ions.

As the desired concentration is much lower than the initial concentration, we can assume that the OH⁻ concentration will be equal to the change in Al³⁺ concentration.

By using the solubility product expression,

Ksp = [Al³⁺][OH⁻]³, and substituting the given values, we have (2.00 x 10⁻⁷+ Δ[Al³⁺])(Δ[Al³⁺])³ = (2.50 x 10⁻² - Δ[Al³⁺])(2.50 x 10⁻² - Δ[Al³⁺])³.

Solving this equation will yield the value of Δ[Al³⁺], which corresponds to the change in Al³⁺ concentration. Subtracting this value from the initial Al³⁺ concentration of 2.50 x 10⁻² M will give us the desired concentration of 2.00 x 10⁻⁷ M.

Answer:

An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Forces are "pushes" or "pulls" on the object, and forces, like velocity and acceleration are vector quantities.

Answer:

Final velocity = 7.677 m/s

KE before crash = 202300 J

KE after crash = 182,702.62 J

Explanation:

We are given;

m1 = 1400 kg

m2 = 4700 kg

u1 = 17 m/s

u2 = 0 m/s

Using formula for inelastic collision, we have;

m1•u1 + m2•u2 = (m1 + m2)v

Where v is final velocity after collision.

Plugging in the relevant values;

(1400 × 17) + (4700 × 0) = (1400 + 1700)v

23800 = 3100v

v = 23800/3100

v = 7.677 m/s

Kinetic energy before crash = ½ × 1400 × 17² = 202300 J

Kinetic energy after crash = ½(1400 + 1700) × 7.677² = 182,702.62 J

The weight of the wood block when it is in the air can be determined with the help of Archimedes' principle.

Archimedes' principle states that the weight of a body that is submerged in a fluid is equal to the weight of the fluid that is displaced by it.

Hence, we can say that when the wood block floats in water, it displaces 0.006 m3 of water. This means that the weight of the wood block is equal to the weight of water displaced by it.

Therefore, the weight of the wood block when it is in the air can be determined by finding the weight of 0.006 m3 of water.

The density of water is 1 g/cm3.

Since 1m³ = 1000000 cm³,

We can say that the mass of 1 m3 of water is 1000 kg, or 106 g.

Hence, the mass of 0.006 m3 of water is 0.006 x 106 g, or 6000 g.

Therefore, the weight of 0.006 m3 of water is 6000 x 9.8 N, or 58800 N.

Hence, the weight of the wood block when it is in the air is 58800 N.

Explanation:

The total number of revolutions undergone by the tub during the entire time interval is 23.1 revolutions.

To determine the total number of revolutions, we need to calculate the angular displacement of the tub during the starting phase, the stopping phase, and the constant speed phase.

During the starting phase, the tub goes from rest to its maximum angular speed of 2.2 rev/s. We can use the equation of motion for angular acceleration:

ω = ω₀ + αt

Given that ω₀ = 0 (initial angular speed) and ω = 2.2 rev/s (final angular speed), and t = 6.8 s (time), we can solve for α (angular acceleration). Using this angular acceleration, we can calculate the angular displacement (θ) during the starting phase.

During the stopping phase, the tub decelerates and comes to a stop. The angular displacement during this phase can be calculated using the same equation of motion for angular acceleration, with ω = 0 (final angular speed), ω₀ = 2.2 rev/s (initial angular speed), and t = 14.5 s (time).

Finally, during the constant speed phase, the angular displacement is given by ωt, where ω is the constant angular speed of 2.2 rev/s and t is the time interval between the end of the starting phase and the beginning of the stopping phase.

Adding up the angular displacements from each phase will give us the total angular displacement, which can be converted to the total number of revolutions by dividing it by 2π.

Calculating these values will result in a total of 23.1 revolutions undergone by the tub during the entire time interval.

The classification of stars based on their spectral type follows the sequence O, B, A, F, G, K, and M, with O-type stars being the hottest and M-type stars being the coolest. The habitable zone, also known as the "Goldilocks zone," refers to the region around a star where conditions may be suitable for the existence of liquid water on the surface of a planet.

G-type stars, such as our Sun (classified as G2V), are considered to be within the optimal range for habitability. These stars have a stable and long-lasting main sequence phase, providing a relatively steady energy output over billions of years. Planets orbiting within the habitable zone of a G-type star have the potential to maintain a stable climate, with the right conditions for liquid water to exist. While other star types like F-type, K-type, and even some M-type stars can have habitable zones, G-type stars are generally considered to provide more favourable conditions for life.
