Answer:

a) -1.25 m/s²

b) 62.5 m

Explanation:

Convert km/h to m/s:

45 km/h × (1000 m/km) × (1 h / 3600 s) = 12.5 m/s

a = Δv / Δt

a = (0 m/s − 12.5 m/s) / 10 s

a = -1.25 m/s²

Δx = ½ (v + v₀) t

Δx = ½ (0 m/s + 12.5 m/s) (10 s)

Δx = 62.5 m

The correct answer is Einstein proposed that light must be made up of packets to explain the photoelectric effect (particles). The frequency of a light packet affects how much energy it contains. Whether or not a single photon has enough energy to knock an electron loose determines whether or not a metal will emit electrons.

The kinetic energy of the electrons is precisely proportional to intensity because, according to wave theory, the energy of electromagnetic waves is uniformly distributed over the wavefront and solely depends on the intensity of the input light beam. However, it was discovered through experimentation that the kinetic energy is unrelated to the brightness of the incident light.

The first part of the graph shows that the acceleration is minimal as the velocity does not increase much in the upwards journey. It is stationary at the maximum height and is greatly accelerated by gravity until it falls to the ground. Option B

The velocity-time graph under gravity for an object that is dropped from a certain height and experiences free fall acceleration due to gravity would be a straight line with a constant slope.

The slope of the graph represents the acceleration, which is constant at approximately 9.8 meters per second squared (m/s²) near the surface of the Earth. The velocity of the object would increase uniformly with time, and the graph would show a linear increase in the vertical direction, with time on the horizontal axis and velocity on the vertical axis.

As the capacitance is increased in a capacitor connected across an AC source, the current through the capacitor will decrease.

In an AC circuit, the behavior of a capacitor is determined by its reactance, which is the opposition to the flow of alternating current. The reactance of a capacitor is inversely proportional to its capacitance (Xc = 1 / (2πfC), where Xc is the capacitive reactance, f is the frequency, and C is the capacitance).

When the capacitance is increased, the capacitive reactance decreases. According to Ohm's Law in AC circuits (I = V / Xc), a decrease in reactance results in an increase in current. Conversely, as the reactance increases, the current decreases. Therefore, as the capacitance in a capacitor connected to an AC source is increased, the current through the capacitor will decrease.

Work done on the can of soup by the attendant is 3J.

A supermarket checkout attendant can do a considerable amount of work on a can of soup when they apply a force of 5.00 N over a distance of 0.600 m.

Work is defined as the product of force and displacement and is calculated by multiplying the force applied (5.00 N) by the distance moved (0.600 m). Therefore, the work done on the can of soup is:

5.00 N * 0.600 m = 3.00 Nm.

To understand this concept further, it's important to know that the unit of work, joule (J), is equal to 1 Newton meter (Nm). So, the 3.00 Nm of work done on the can of soup is also equal to 3.00 J.

The amount of work done on the can of soup by the checkout attendant is directly proportional to the amount of force and displacement applied. If either of the two is increased, then the total work done will increase.

For example, if the checkout attendant applies a force of 10.00 N over a distance of 0.600 m, then the total work done will be 10.00 N * 0.600 m = 6.00 Nm, or 6.00 J.

In conclusion, a supermarket checkout attendant can do a considerable amount of work on a can of soup when they apply a force of 5.00 N over a distance of 0.600 m. This work is equal to 3.00 Nm or 3.00 J.

The net effect of the sodium-potassium pump is to create a transmembrane electrical potential.

Sodium-potassium pump is a process in which sodium ions (Na+) are transported out of the cell while potassium ions (K+) are transported into the cell. The net effect of this process is that there is a greater concentration of K+ ions inside the cell and a greater concentration of Na+ ions outside the cell.

This creates an electrochemical gradient across the cell membrane. This gradient is what allows cells to carry out a variety of functions such as transmitting signals and carrying out metabolic processes. The electrochemical gradient is also what drives the movement of other molecules across the cell membrane.

Resistance to the flow of electricity in wires and resistance to the flow of water in pipes are similar in several ways:

Both are affected by the size of the conductor: In both cases, the resistance to flow is affected by the size of the conductor. A larger diameter wire or pipe will offer less resistance to the flow of electricity or water than a smaller diameter one.

Both are affected by the length of the conductor: The resistance to flow also increases with the length of the conductor. A longer wire or pipe will offer more resistance to the flow of electricity or water than a shorter one.

Both are affected by the material of the conductor: Different materials have different resistances to flow. In electrical wires, metals are commonly used as they have low resistance. In pipes, materials such as copper, plastic, or steel may be used depending on the specific application.

Both can be reduced by minimizing obstructions: Resistance to flow can be reduced in both cases by minimizing obstructions in the path of the flow. In pipes, for example, the use of smooth inner walls and proper pipe bends can help reduce resistance. In electrical wires, minimizing the number of connections and using high-quality connections can help reduce resistance.

Overall, resistance to flow is a fundamental concept that applies to the flow of electricity and water, and the factors affecting resistance are similar in both cases.

The diver will hit the water after 9/4 seconds.

To find the time when the diver hits the water, use the equation 16t² = 81. To find t, follow these steps:

1. Divide both sides of the equation by 16: t² = 81/16
2. Take the square root of both sides: t = √(81/16)
3. Simplify: t = 9/4 seconds


To calculate the velocity of the diver when they hit the water, use a = 9/4 seconds. The distance when the diver hits the water is d(a) = 16(9/4)² = 81 ft.

The swept volume of the cylinder is 0.036 m^3, the delivery temperature is 110.5 degrees C, and the indicated mean effective pressure is 5.6 bar.

The swept volume of the cylinder can be calculated using the following equation:

V_s = m * V_d / (1 - r)

where:

* V_s = swept volume of the cylinder (m^3)

* m = mass flow rate (kg/s)

* V_d = delivery volume (m^3)

* r = clearance ratio

Plugging in the values, we get:

V_s = 8 m^3/min * 0.001666667 m^3/kg / (1 - 0.05) = 0.036 m^3

The delivery temperature can be calculated using the following equation:

T_d = T_1 * (P_2 / P_1)^(1 - k / 2)

where:

* T_d = delivery temperature (degrees C)

* T_1 = inlet temperature (degrees C)

* P_2 = outlet pressure (bar)

* P_1 = inlet pressure (bar)

* k = adiabatic index (1.3)

Plugging in the values, we get:

T_d = 15 degrees C * (6 bar / 1.013 bar)^(1 - 1.3 / 2) = 110.5 degrees C

The indicated mean effective pressure can be calculated using the following equation:

P_imep = m * R * T_d / V_s

where:

* P_imep = indicated mean effective pressure (bar)

* m = mass flow rate (kg/s)

* R = universal gas constant (8.314 kJ/kg K)

* T_d = delivery temperature (degrees C)

* V_s = swept volume of the cylinder (m^3)

Plugging in the values, we get:

P_imep = 8 m^3/min * 8.314 kJ/kg K * 110.5 degrees C / 0.036 m^3 = 5.6 bar

The law of motion best demonstrated when a person in a wheelchair gains speed when he/she pushes on the rims is the Law of acceleration.

The relationship between an object's motion and the forces acting on it is outlined by Newton's laws of motion, which are three fundamental principles of classical mechanics. The following can be used to paraphrase these laws: Unless a force acts on a body, it stays at rest or moves in a straight line at a constant speed. The force acting on a body is equal to the time rate at which its momentum changes. When two bodies interact, forces are generated that are equal in magnitude but directed in different directions. These three laws of motion help us to understand how objects behave when standing still, when moving and when forces act upon them. According to Newton's second law, a body's acceleration is inversely related to its mass and directly related to the net force acting on it. Force and mass both affect how quickly an object accelerates.
