(A). The force acting on the rocket is mg.

(B). The initial upward acceleration of the rocket is 6.2 m/s²

Explanation:

Given that,

Mass of rocket = 5 kg

Force = 80 N

Time = 4 sec

(A). We need to draw the figure

The force acting on the rocket at each of the intervals is shown in figure.

The force acting on the rocket is mg.

(B). We need to calculate the initial upward acceleration of the rocket

Using balance equation

\(ma=F-mg\)

\(a=\dfrac{F-mg}{m}\)

Put the value in the equation

\(a=\dfrac{80-5\times9.8}{5}\)

\(a=6.2\ m/s^2\)

Hence, (A). The force acting on the rocket is mg.

(B). The initial upward acceleration of the rocket is 6.2 m/s²

True. The general principle is that the hotter the surface, the shorter the wavelengths of light that are emitted.

What is called a wavelength?

Wavelength is a measure of the distance between repeating units of a wave, such as a sound wave or light wave. It is measured in meters (m) and typically represented by the Greek letter lambda (λ). Wavelengths of different light colors have different values, with red typically having the longest wavelength and violet having the shortest. Wavelengths of sound can also vary, with low-frequency sounds having longer wavelengths than high-frequency sounds.

This is because the hotter an object is, the more energy its atoms and molecules have, and they emit light with higher frequencies, which correspond to shorter wavelengths. This is known as Wien's law, which states that the wavelength of maximum radiation emitted by an object is inversely proportional to its temperature.

Therefore, True is the correct answer.

Explanation:Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.

In a fire piston, the temperature of the gas inside the piston increases due to adiabatic compression.

In physics, pressure is a measure of the force per unit area that a fluid (liquid or gas) exerts on its surroundings. It is defined as the force F acting perpendicular to a surface divided by the area A over which the force is distributed: pressure = F/A. The SI unit of pressure is the Pascal (Pa), which is defined as one Newton per square meter (N/m²). Other common units of pressure include pounds per square inch (psi), atmospheres (atm), and bar (bar). Pressure is an important concept in many areas of physics, including fluid mechanics, thermodynamics, and atmospheric science. It describes the behavior of fluids in pipes and channels, the operation of hydraulic systems, and the behavior of gases in sealed containers. The pressure of a fluid is related to its density and temperature, and can be influenced by factors such as gravity, elevation, and the motion of the fluid itself.

Here,

When the piston is rapidly pushed down into the cylinder, it compresses the gas inside the cylinder. This rapid compression causes the gas molecules to collide with each other more frequently and with greater force, which in turn increases the temperature of the gas.

Because the compression is adiabatic (i.e., no heat is allowed to enter or leave the system), the increase in temperature is due solely to the work done on the gas by the piston. This increase in temperature is known as adiabatic heating.

The fire piston is a simple but effective tool for starting a fire in the wilderness, and it demonstrates the principles of adiabatic compression and the relationship between pressure, volume, and temperature in a gas.

The potential energy is zero since the rock isn't moving.

Answer:

50 Joules

Explanation:

The car is traveling at an exact speed of approximately 164.97 kmph.

To find the speed of the car, we can relate the angular velocity of the wheels to the linear velocity of the car using the formula:

v = ω × r

where

v is the linear velocity of the car,

ω is the angular velocity of the wheels, and

r is the radius of the wheels.

Given:

Diameter of the wheels = 65.0 cm

Radius of the wheels = (65.0 cm) / 2 = 32.5 cm = 0.325 m

Angular velocity of the wheels (ω) = 141 rad/s

Substituting these values into the formula, we have:

v = ω × r

v = (141 rad/s) × (0.325 m)

Calculating:

v ≈ 45.825 m/s

Converting the speed to kilometers per hour:

v = 45.825 m/s × (3.6 km/h) / (1 m/s)

Calculating:

v ≈ 164.97 km/h

Therefore, the car is moving at approximately 164.97 km/h.

Answer:

Explanation:

Sound, seismic, and electromagnetic waves transmit energy through different mediums due to the motion of particles in the medium.

Sound waves transmit energy through the vibration of particles in a solid, liquid, or gas. The energy is transferred from particle to particle as the wave travels through the medium.

Seismic waves are created by the sudden release of energy from earthquakes, volcanic eruptions, or other geological events. These waves travel through the Earth's solid mantle and crust, transmitting energy through the vibration of particles in the rock.

Electromagnetic waves are a type of wave that does not require a medium to travel through. They are created by the motion of charged particles, such as electrons, and can travel through a vacuum, such as space. Electromagnetic waves transfer energy through the oscillation of electric and magnetic fields.

When waves spread out when they pass through a hole or past the edge of a barrier, this is called diffraction.

An interruption that moves momentum and energy from one place in a medium to another is known as a wave. For instance, we can observe the movement of the wave crest from one side to the other in a specific amount of time as an ocean wave moves in medium water.

Most often, wind is what produces waves. The rubbing together of wind and surface water produces wind-driven waves, also known as surface waves. A wave crest is produced when wind continuously disturbs the ocean or lake's surface while it blows across it.

To find the speed at which the bicycle is traveling, we can use the formula that relates the circumference of the wheel to the distance covered in one revolution. By multiplying the circumference by the number of revolutions per minute, we can determine the speed of the bicycle.

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle. In this case, the bicycle wheels have a diameter of 26 inches, so the radius is half of that, which is 13 inches. Converting the diameter to inches, the circumference of each wheel is 2π(13) = 26π inches.

Given that the wheels are rotating at 160 RPM, we can multiply the circumference by the number of revolutions per minute to find the distance covered in one minute. This can be converted to the speed in inches per minute.

To obtain the speed in a more common unit, we can convert inches per minute to miles per hour by using appropriate conversion factors. Finally, rounding the answer to three decimal places provides the speed at which the bicycle is traveling down the road.

Answer:

The diagram shows a net 2 N  in the north direction and 2 N in the east direction - this would result in (4 + 4)^1/2 to the northeast.

Answer:

Below

Explanation:

135 lbs  *  1 kg/2.2 lb  = ~ 61.4 kg

there are 1000 mg in each gram

5.3 mg   *  1 gm / 1000 mg = .0053 g

The metal's specific heat is 1.97 J/g°C.

To determine the specific heat of the masses in this experiment, we need to know the amount of heat required to raise their temperature by a certain amount. We can calculate this by using the formula:
Q = m * c * ΔT
where Q is the amount of heat absorbed, m is the mass of the substance, c is the specific heat of the substance, and ΔT is the change in temperature.
Unfortunately, the problem doesn't provide us with the necessary data to calculate the specific heat of the masses. Therefore, we cannot infer the substance the masses are made of without additional information.
However, we can calculate the specific heat of the metal using the given data. We know that the heat lost by the hot metal is equal to the heat gained by the cold water. So, we can use the formula above to solve for c:
Q_hot = Q_cold
m_hot * c_hot * ΔT_hot = m_cold * c_water * ΔT_cold
c_hot = (m_cold * c_water * ΔT_cold) / (m_hot * ΔT_hot)
Plugging in the given values, we get:
c_hot = (500 g * 4.18 J/g°C * 17.5°C) / (200 g * 40°C)
c_hot = 1.97 J/g°C
Therefore, the metal's specific heat is 1.97 J/g°C. To determine the metal, we can compare this value to the specific heats of known metals. For example, the specific heat of copper is 0.39 J/g°C, which is much lower than our calculated value. This rules out copper. Similarly, the specific heat of aluminum is 0.91 J/g°C, which is still lower than our calculated value. This leaves us with only a few possibilities, such as iron or lead, which have specific heats closer to 1.97 J/g°C. Without further information, we cannot determine the exact metal with certainty.

To find the maximum speed the car can travel without slipping, you can use the formula:

v = sqrt(μ * g * r)

where v is the maximum velocity, μ is the coefficient of friction, g is the acceleration due to gravity (9.8 m/s^2), and r is the radius of the turn.

Plugging in the given values, you get:

v = sqrt(0.60 * 9.8 m/s^2 * 75 m) = sqrt(45.9 m^2/s^2) = 6.8 m/s

So the maximum speed the car can travel without slipping is approximately 6.8 m/s.

It's important to note that this formula assumes that the car is following a circular path around the turn and that the friction force is the only force acting on the car. If either of these conditions is not met, the actual maximum speed may be slightly different.
