The disadvantage of a lightweight camera, when snapping the shutter, is poor balance which gives distraction in taking steady photograph.

As a quality of an item that resists modifications to its state of motion, inertia can be defined. It is an inherent property of the object that is related to its mass and informs us of the amount of force necessary to produce the specific acceleration on the object.

Inertia is defined by the First Law of Motion, which states that an item continues in motion or at a constant speed until an external force is applied to it.

Light weight cameras have low inertia, that's why, it moves in less amount of force which creates distraction in photography. So, most photographers prefer a massive tripod.

Answer:

A

Explanation:

Answer: A

Explanation:

It will takes approximately 0.165 seconds for the ball to reach the floor after it has been gently pushed off the table top from a height of 1.3 m above the floor.

When an object is dropped from a height, it falls to the ground due to the force of gravity.

When an object is released from a height of 1.3 m above the ground, the time it takes to reach the ground is calculated using the formula:

h = 0.5gt²  where h is the height of the object, g is the acceleration due to gravity and t is the time taken for the object to reach the ground.

Rearranging this formula to solve for t, we have: \(t = \sqrt{(2h/g)}\)

Substituting the values we have: \(h = 1.3 mg = 9.81 m/s^{2} t = \sqrt{(2 \times 1.3 / 9.81)t} = \sqrt{(0.265 / 9.81)t} = \sqrt{0.027t } = 0.165 seconds\)

Therefore, it takes approximately 0.165 seconds for the ball to reach the floor after it has been gently pushed off the table top from a height of 1.3 m above the floor.

The coefficient of kinetic friction is approximately 0.102.

The  coefficient of kinetic friction is calculated by using the following formula;

frictional force = coefficient of kinetic friction x normal force

Since the object is not accelerating, we know that the force of gravity pulling down on the object is equal and opposite to the normal force pushing up on the object. Therefore, we can use the formula:

normal force = weight of the object = mass x gravity

where;

So, the normal force on the object is:

normal force = 95 kg x 9.8 m/s^2 = 931 N

Now we can substitute the values we have into the formula for coefficient of kinetic friction:

95 N = coefficient of kinetic friction x 931 N

Solving for the coefficient of kinetic friction, we get:

coefficient of kinetic friction = 95 N / 931 N ≈ 0.102

a) The model for the velocity of a falling body with air resistance can be described using Newton's second law of motion. The equation can be written as:

m * dv/dt = mg - k * v^2

where m is the mass of the body, g is the acceleration due to gravity, k is the proportionality constant for air resistance, and v is the velocity of the body.

Assuming the ratio of k to m is unity, we can rewrite the equation as:

dv/dt = g - v^2

To solve this first-order ordinary differential equation, we can separate variables and integrate:

∫ 1/(g - v^2) dv = ∫ dt

After integration, we obtain:

atan(v/sqrt(g)) = t + C

Solving for v, we have:

v(t) = sqrt(g) * tan(t + C)

Given an initial velocity of 12 m/s, we can determine the value of C. Plugging in the values, we have:

12 = sqrt(g) * tan(C)

Now, we can solve for C using the given information.

b) To determine how long it will take for the cake to cool off to 75 °F, we can use Newton's law of cooling, which states that the rate of temperature change of an object is proportional to the difference between its temperature and the surrounding temperature. The equation can be written as:

dT/dt = -k(T - T_room)

where dT/dt is the rate of temperature change, T is the temperature of the cake, T_room is the room temperature, and k is the proportionality constant.

Separating variables and integrating, we get:

∫ 1/(T - T_room) dT = -k ∫ dt

After integration, we have:

ln|T - T_room| = -kt + C

Solving for T, we obtain:

T(t) = T_room + Ce^(-kt)

Given that the initial temperature is 300 °F and the desired temperature is 75 °F, we can determine the value of C. Plugging in the values, we have:

300 = 75 + Ce^0

Solving for C, we find:

C = 225

Now, we can determine the time it takes for the cake to cool to 75 °F by solving for t when T = 75 and plugging in the values.

Please note that the specific values of the proportionality constants and units are not provided in the question, so the final numerical results will depend on those values.

The transformation of protoliths into metamorphic rocks solely through the transfer of heat is termed "contact" metamorphism.

Contact metamorphism refers to the changes that occur in rocks when they come into direct contact with a heat source, such as a magma intrusion or a lava flow. In this type of metamorphism, the heat from the surrounding molten material causes the protoliths (pre-existing rocks) to undergo changes in mineral composition, texture, and structure. The heat-driven alteration occurs primarily due to the transfer of thermal energy, without significant pressure or deformation. The intensity and extent of contact metamorphism depend on factors like temperature, duration of heating, and the nature of the rocks involved.

Explanation:

Answer:

The total distance between A and B is 30 km

Explanation:

The given information are;

The time duration of the acceleration of the train from station A = 3 minutes = 0.05 hours

The speed attained by the train after the acceleration = 144 km/h

The time duration the train maintains the speed = 10 minutes = 0.1\(\bar 6\) hours

The time duration in which the train decelerates to station B = 2 minutes = 0.0\(\bar 3\) hours

The equation of motion required are;

The initial acceleration, a = (144 - 0)/0.05 = 2,880 km/h²

The distance covered, s = u·t + 1/2·a·t²

Where;

u The initial velocity = 0

∴ s₁ = 0 × 0.05 + 1/2 × 2880 × 0.05² = 3.6 km

s₁ = 3.6 km

The distance, s₂ the train covers at the constant speed 144 km/h for 10 minutes (1/6 hours) is given as follows;

s₂ = Velocity Time = 144 × 1/6 = 24 km

s₂ = 24 km

The deceleration, a₂ that brings the train to a stop in 2 minutes (1/30 hours) is given as follows;

a₂ = (0 - 144)/(1/30) = -4320 km/h²

The distance covered, s₃ by the train as it decelerates to rest from the initial constant speed is given as follows;

s₃ = u·t + 1/2·a·t²

Where;

u = The initial velocity =144 km/h

We have;

s₃ = 144×1/30 - 1/2 × 4320 × (1/30)² = 2.4

s₃ = 2.4 km

The total distance between A and B, s = s₁ + s₂ + s₃ = 3.6 + 24 + 2.4 = 30 km

The total distance between A and B = 30 km.

Answer: Therefore, the instantaneous speed is only the answer, because, the detector can only detect the instantaneous speed but not the average speed.

The coefficient of kinetic friction between the calculus book and the floor in the pickup game of dorm shuffleboard is approximately 0.183. This value represents the ratio of the net force acting on the book, which is the difference between the applied force from the broom and the force of friction, to the weight of the book.

To determine the coefficient of kinetic friction between the book and the floor, we can use the following equation:

μk = (F_net - F_applied) / (m * g),

where μk is the coefficient of kinetic friction, F_net is the net force acting on the book, F_applied is the applied force from the broom, m is the mass of the book, and g is the acceleration due to gravity.

In this scenario, the applied force from the broom is 49 N, and the mass of the book is 4.9 kg. The net force can be calculated using Newton's second law, which states that F_net = m * a, where a is the acceleration.

To find the acceleration, we can use the equation:

\(v^2\) = \(u^2\) + 2 * a * s,

where v is the final velocity, u is the initial velocity (0 m/s in this case since the book starts from rest), a is the acceleration, and s is the distance traveled.

Plugging in the given values, we have:

\((1.4 m/s)^2\) = \((0 m/s)^2\) + 2 * a * 0.90 m.

Simplifying the equation gives us:

1.96\(m^2\)/\(s^2\)= 1.8 m * a.

Solving for a, we find:

a = 1.96\(m^2\)/\(s^2\) / 1.8 m = 1.0889 \(m/s^2\).

Now we can calculate the net force:

F_net = m * a = 4.9 kg * 1.0889\(m/s^2\) = 5.335 N.

Substituting the values into the equation for the coefficient of kinetic friction:

μk = (F_net - F_applied) / (m * g) = (5.335 N - 49 N) / (4.9 kg * 9.8 \(m/s^2\)) ≈ 0.183.

Therefore, the coefficient of kinetic friction between the book and the floor is approximately 0.183.

Therefore, the ranking of the wires from most to least electron current is: Wire A > Wire B > Wire D > Wire C.

To rank the wires in order of decreasing electron current, we need to consider the factors that affect the current in a wire. The electron current in a wire is determined by the drift speed of the electrons and the cross-sectional area of the wire.
The drift speed of electrons refers to the average velocity at which electrons move through the wire. A higher drift speed means that the electrons are moving faster and therefore the current will be greater.
The cross-sectional area of the wire refers to the size of the wire's cross-section. A larger cross-sectional area allows for more electrons to flow through the wire, resulting in a greater current.
To rank the wires, we need to compare the drift speeds and cross-sectional areas of each wire.
1. Wire A: If wire A has a larger drift speed and a larger cross-sectional area compared to the other wires, it will have the highest electron current.
2. Wire B: If wire B has a smaller drift speed but a larger cross-sectional area compared to the other wires, it will have a lower electron current than wire A but higher than the remaining wires.
3. Wire C: If wire C has a smaller drift speed and a smaller cross-sectional area compared to wire B, its electron current will be lower than both wire A and wire B.
4. Wire D: If wire D has a larger drift speed but a smaller cross-sectional area compared to wire B, its electron current will be lower than wire B but higher than wire C.
Please note that the specific values of the radius and drift speed are not given, so we cannot determine the exact order without more information.

The **efficiency** of the car is calculated by dividing the useful energy output by the total energy input, and then multiplying by 100 to express it as a percentage. In this case, we need to determine the energy input and output.

The energy input can be calculated by multiplying the amount of gasoline consumed (0.0766 liters) by the energy content per liter (3.2×10^7 J/l). This yields an energy input of approximately 2.4512×10^6 J.

The energy output can be determined using the kinetic energy formula: KE = (1/2)mv^2, where m is the mass of the car (810 kg) and v is the final velocity (29 m/s). Plugging in these values, we find the energy output to be 329,805 J.

To calculate the efficiency, we divide the energy output by the energy input and multiply by 100: (329,805 J / 2,451,200 J) × 100 = 13.46%.
