The acceleration with which the car uniformly increases its speed from zero to the given speed is 5m/s².

Given the data in the question

Since the car was initially at rest

Acceleration of the car; \(a = \ ?\)

Using the First Equation of Motion:

\(v = u + at\)

Where u is the initial velocity, v is the final velocity, a is the acceleration and t is the time taken.

We substitute our given values into the equation and solve for "a"

\(10m/s = 0m/s\ +\ ( a * 2s ) \\\\10m/s = a * 2s\\\\a = \frac{10m/s}{2s}\\\\a = 5m/s^2\)

Therefore, the acceleration with which the car uniformly increases its speed from zero to the given speed is 5m/s².

The plotting on a speed-time graph for the motion of a car is accelerated with increasing speed will be, a curved line sloping upward whose slope is increasing .

The rate of change of distance is known as speed of an object . It is denoted by S and unit is m/s . Speed of an object can never be negative.

S = dx/dt

Where , dx and dt are small change in distance and time .

The curved line can be understand as, speed-time graph is a curved line, that means its slope changes at every instant which implies that the acceleration of the body changes at every instant.

Acceleration is the rate of change of the velocity of an object with respect to time. Itsw unit is m/s² and can be given as,

a = dv/dt

Where , dv and dt is the small change in velocity and time of an object.

Hence , whenever  an object is undergoing constant acceleration , the line on the graph is straight but sloped .

Speed is always plotted on the vertical axis and time is always plotted on the horizontal , therefore a straight line shows distance - time graph and speed-time graph for the motion of a car is curved line sloping upward whose slope is increasing .

The magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹ (Option E).

The electric flux through a surface is given by the product of the electric field strength and the area of the surface projected perpendicular to the electric field.

In this case, the electric field strength is 18 N C⁻¹, and the area of the sheet projected perpendicular to the electric field is 0.450 m²

(since the normal to the sheet makes an angle of 60° with the electric field). Multiplying these values gives the electric flux:

Electric flux = Electric field strength × Area

Electric flux = 18 N C⁻¹ × 0.450 m²

Electric flux = 8.1 N m² C⁻¹

In summary, the magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹. This value is obtained by multiplying the given electric field strength by the projected area of the sheet perpendicular to the electric field.

The angle of 60° is taken into account to determine the effective area for calculating the flux.(Option E).

The car is moving at approximately 12.5 meters per second.

The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * \(v^2\)

where

KE = kinetic energy,

m =Mass of the object, and

v = velocity.

In this case, we are given the mass (m) of the car as 1600 kg and the kinetic energy (KE) as 125,000 J. To find the velocity .

Substituting the  values , we have:

125,000 J = 1/2 * 1600 kg *\(v^2\)

Now, we can solve for v by rearranging the equation:

\(v^2\) = (2 * 125,000 J) / 1600 kg

\(v^2\) = 156.25 \(m^2/s^2\)

Taking the square root, we find:

v = √156.25\(m^2/s^2\)

v ≈ 12.5 m/s

To calculate the torque required to create an angular acceleration, we can use the formula:

Torque = Moment of Inertia × Angular Acceleration

The moment of inertia of a disk can be calculated using the formula:

Moment of Inertia = (1/2) × Mass × Radius^2

Given:

Mass = 15,000 kg

Radius = 6.14 m

Angular Acceleration = 0.0500 rad/s^2

First, calculate the moment of inertia:

Moment of Inertia = (1/2) × Mass × Radius^2

Moment of Inertia = (1/2) × 15,000 kg × (6.14 m)^2

Next, calculate the torque:

Torque = Moment of Inertia × Angular Acceleration

Torque = Moment of Inertia × 0.0500 rad/s^2

Now, let's plug in the values and calculate:

Moment of Inertia = (1/2) × 15,000 kg × (6.14 m)^2

Moment of Inertia ≈ 283,594.13 kg·m^2

Torque = 283,594.13 kg·m^2 × 0.0500 rad/s^2

Torque ≈ 14,179.71 N·m

Rounding to three significant figures, the torque required to create an angular acceleration of 0.0500 rad/s^2 is approximately 14,180 N·m.

Answer:

C. The solid sphere will reach the bottom first.

E. The solid sphere will reach the bottom with the greater kinetic energy.

Explanation:

To answer this,the sphere that has the smaller mass moment of inertia will be the one that will have the largest acceleration down the plane. And we know that higher acceleration means higher speed.

Now, moment of inertia of both spheres are;

I_solid sphere = (2/5)mr² = 0.4mr²

I_hollow sphere = (2/3)mr² = 0.67 mr²

Now, it is clear that the solid sphere has the smaller mass moment of inertia. This means that the solid sphere will have more acceleration and as well higher speed and will thus reach the bottom first.

Also, the higher the speed, the higher the kinetic energy since K.E = ½mv².

Thus, options C & E are correct.

The total momentum of the system before the split is 96 u*m/s.

The total momentum of the system before the split can be calculated by adding the individual momenta of the atoms. Momentum is the product of mass and velocity.

The first atom has a mass of 96 u and is traveling at a velocity of 1000 m/s, resulting in a momentum of 96 um/s.

The second atom has a mass of 82 u and a velocity of 500 m/s, giving it a momentum of 82 um/s.

Adding these two momenta together, we get a total momentum of 178 u*m/s for the system before the split.

The flow speed of the fluid in the wider section of the pipe is x^2/3 m/s. The correct option is d.

Since the pipe is infinitely long, the mass flow rate of the fluid is constant throughout the pipe. Therefore, the product of the density, cross-sectional area, and flow speed is also constant throughout the pipe.

Let's assume that the density of the fluid is ρ and the diameter of the narrower section is x cm. Then, the cross-sectional area of the narrower section is πx^2/4. From the given information, the flow speed in the narrower section is 3 m/s.

Using the equation of continuity,

A1V1 = A2V2

π(4/2)^2V1 = πx^2/4 * 3

V1 = (3/16) * (16x^2/3) = x^2/3

Therefore, the flow speed of the fluid in the wider section of the pipe is x^2/3 m/s. Hence, the correct option is (D).

A piece of copper at 100°C is transferred to a copper calorimeter with a liquid at 30°C. The final temperature is 50°C. By applying the principle of conservation of energy, the specific heat capacity of the liquid is calculated to be approximately 2100 J/kg/°C.

To calculate the specific heat capacity of the liquid, we can apply the principle of conservation of energy. The heat lost by the copper piece will be equal to the heat gained by the liquid and calorimeter.

The heat lost by the copper piece can be calculated using the formula:

Heat lost = Mass of copper × Specific heat capacity of copper × Temperature change

Given:

Mass of copper = 400 g

Specific heat capacity of copper = 390 J/kg/°C (assuming it remains constant)

Temperature change of copper = 100°C - 50°C = 50°C

Heat lost = 400 g × 390 J/kg/°C × 50°C

Heat lost = 7,800,000 J

The heat gained by the liquid and calorimeter can be calculated using the formula:

Heat gained = (Mass of liquid + Mass of calorimeter) × Specific heat capacity of liquid × Temperature change

Given:

Mass of liquid = 100 g

Mass of calorimeter = 10 g

Temperature change of liquid = 50°C - 30°C = 20°C

Heat gained = (100 g + 10 g) × Specific heat capacity of liquid × 20°C

Now, by equating the heat lost and heat gained:

7,800,000 J = (110 g) × Specific heat capacity of liquid × 20°C

Specific heat capacity of liquid = 7,800,000 J / (110 g × 20°C)

Specific heat capacity of liquid ≈ 3545.45 J/kg/°C

Therefore, the specific heat capacity of the liquid is approximately 3545.45 J/kg/°C.

The probability that the basketball player makes 1 shot is 0.435 or approximately 43.5%.

This is a binomial distribution problem, where we have a fixed number of trials (3 free throws) and each trial has two possible outcomes (make or miss) with a fixed probability of success (39%).

The probability of making exactly 1 shot can be calculated using the binomial probability formula:

\(P(X = k) = (n choose k) * p^k * (1-p)^{(n-k)} ^\)

Where:

n is the number of trials (3)

k is the number of successes (1)

p is the probability of success on each trial (0.39)

Plugging in the values, we get:

\(P(X = 1) = (3 choose 1) * 0.39^1 * (1-0.39)^{(3-1)}\)

= \(3 * 0.39 * 0.61^2\)
