what is the component of your displacement in the x-direction, in meters?

Speed of river = 1.6 km/h

Speed of river = (4 km - 1 km) / Time

Time = (4 km + 1 km) / 2 km/h

Time = 5/2 hours = 2.5 hours

Speed of river = (4 km - 1 km) / 2.5 hours

Speed of river = 1.6 km/h

What is speed?

Speed is a measure of how quickly an object is moving. It is the rate of change in the object's position over a period of time. It is usually measured in units such as meters per second, kilometers per hour, or miles per hour. Speed is a scalar quantity, meaning it only requires a magnitude to describe it. It is different from velocity, which is a vector quantity, meaning it requires both a magnitude and a direction to describe it. Speed affects the time it takes to travel a given distance, and is also a factor in acceleration and deceleration. Speed is a fundamental concept in physics, and is used to calculate the kinetic energy of an object.

Therefore, Speed of river = 1.6 km/h

The charge of a particle of mass 1.43 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 690 n/c.

What is gravitational force?

Gravitational force is a type of force that exists between any two objects with mass. It is the force of attraction between objects that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them. The strength of gravitational force is determined by the force of gravity, which is determined by the mass of objects and the distance between them.

Charge of Particle = q

Gravitational Force (Fg) = m * g

Electric Force (Fe) = q * E

Fg = Fe

m * g = q * E

q = (m * g) / E

q = (1.43 g * 9.80 m/s²) / (690 n/c)

q = 0.0211 C

Charge (sign and magnitude) of the particle is 0.0211 C.

It would cost $0.0072 to operate a 90 W light bulb for one day if the cost per kilowatt-hour is $0.08.

To solve this problem using the GRASP method, we need to first determine the energy used by the light bulb, then multiply by the cost per kilowatt-hour to find the cost to operate the bulb.

Gather: We are given the power of the bulb (90 W) and the cost per kilowatt-hour ($0.08).

Relate: We need to convert the power of the bulb to kilowatt-hours, which is the unit of energy used in electricity billing.

1 kilowatt-hour = 1000 watt-hours

So, 90 W = (90/1000) kilowatt-hours = 0.09 kilowatt-hours

Apply: We now have the energy used by the bulb and can calculate the cost to operate the bulb for one day.

Cost = energy x cost per kilowatt-hour = 0.09 kilowatt-hours x $0.08 = $0.0072

The following will happen if we looked at a smooth tabletop with a powerful magnifier:

A thin layer of moisture on the surface makes it somewhat 'sticky'

Hence, option (a) is the correct choice.

If you looked at a smooth tabletop with a powerful magnifier, you would likely see very small bumps and grooves on the surface.

These small imperfections in the surface can cause a frictional force to be produced when a block slides across it.

The frictional force is due to the interaction between the small bumps and grooves in the surface and the surface of the block.

The bumps and grooves can create small points of contact between the two surfaces, which resist the motion of the block and produce a frictional force.

This is similar to the way that the sticky notes in the analogy produce a frictional force by sticking to each other.

Answer:

To determine the temperature inside the freezer, you need to calculate the enthalpy of fusion of the 4g of water that froze. The enthalpy of fusion of water is 334 J/g. Thus, the total enthalpy of fusion of the 4g of water is 334 J/g × 4 g = 1336 J. The total heat gained by the water and aluminium is the enthalpy of fusion of the water plus the heat gained by the aluminium by cooling it in the freezer. Since the heat gained by the aluminium is equal to the heat lost by the water, the temperature inside the freezer can be calculated using the equation Q = mcΔT, where Q is the heat transfer, m is the mass of the aluminium, and ΔT is the change in temperature. Thus, the temperature inside the freezer is 1336 J / (260g × 0.90 J/g°C) = 6.2°C

The relationship between pressure, volume, and temperature of a gas can be described by the ideal gas law, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature (in Kelvin).

Since the temperature remains constant, we can assume that the number of moles of gas and the gas constant are also constant. So, we can rearrange the equation to solve for volume: V = nRT / P.

Substituting the given values, we have: V = nRT / 2.00 atm, and V = nRT / 1.00 atm. Dividing these two equations gives us:

V2 / V1 = (2.00 atm) / (1.00 atm) = 2

When a particle is thrown obliquely close to the Earth's surface, it travels along a curved path while experiencing constant acceleration. Always pointing in the direction of the Earth's center is this curving path. Such a particle's motion is referred to as projectile motion, and its trajectory is known as the projectile's trajectory.

In the first stage of a two-stage rocket, the rocket is fired from the launch pad starting from rest but with a constant acceleration of 3.50 m/s² upward. At 25.0 s after launch, the second stage fires for 10.0 s, which boosts the velocity of the rocket to 132.5 m/s upward at 35.0 s after launch.

The formula is

s = ut + 1/2at²

In the initial stage, the velocity is zero, acceleration is a = 3.50 m/s², t = 25 sec.

s = 0 ×25+ 1/2× 3.50 × 25²

s = 1,093.75 m

In the next stage, the initial velocity is 132.5 m/s and at the highest point the velocity is 0 m/s and acceleration is a = -9.8 m/s

v² - u² =2as

0² - 132.5² = 2 × (-9.8) × s

s = 895.73

The maximum height of the rocket is 1,093.75 +  895.73 = 1989.48 m

The value for work done on the system is -89.32 kJ.

In this case, heat has been absorbed by the system, which means the internal energy of the system has increased. Internal energy is defined as the total energy of a system, including its thermal energy, kinetic energy, and potential energy.

The change in internal energy is given by the equation:

ΔU = Q - W

Where ΔU is the change in internal energy, Q is heat transfer into or out of the system, and W is work done on or by the system.

Given the information that 87.33 kJ of heat has been absorbed and the internal energy is 1,999 J, we can calculate the work done on the system:

ΔU = Q - W

ΔU = 87.33 kJ - W

ΔU = 87.33 kJ - W

ΔU = 87.33 x 10^3 J - W

ΔU = 87,330 J - W

ΔU = 87,330 J - W

ΔU = 1,999 J

87,330 J - W = 1,999 J

W = 87,330 J - 1,999 J

W = 85,331 J

W = 85.33 kJ

So the value for work done on the system is -85.33 kJ. This means that 85.33 kJ of energy has been transferred from outside the system to the system due to a force acting over a distance.

The maximum pressure that a pipe can carry before the mercury spills out of an open-end manometer depends on the height of the mercury column and the density of the gas.

An open-end manometer is a device used to measure fluid pressure, usually in a gas or liquid. It consists of a U-shaped tube filled with a liquid, typically mercury or water, and has one end open to the atmosphere.

The pressure of the fluid being measured is transferred to the liquid in the manometer, which results in a change in the height of the liquid column. This change in height can then be used to calculate the pressure, based on the density of the liquid and the height of the column.

The pressure can be calculated using the equation of hydrostatic pressure: Pressure = (density of mercury * acceleration due to gravity * height of mercury column).

The maximum pressure is reached when the pressure exerted by the gas in the pipe equals the pressure exerted by the mercury column, which results in the mercury spilling out of the open end of the manometer.

The total charge entering the element at its upper terminal is the area under the current-time curve for t>=0.

The current-time curve for t>=0 is a linear line with a slope of 20e-5000 A/s. Therefore, the total charge entering the element at its upper terminal is the area of a triangle with base and height equal to the time interval t and the current i, respectively.

The total charge in microcoulombs is given by:

Q = (1/2) (t)(20e-5000t) x 10^6 = 10^6 t^2.

Therefore, the total charge entering the element at its upper terminal is 10^6 t^2 microcoulombs, where t is the time interval.
