Explanation:

Draw free body diagrams for the worker and the load.

The worker has three forces on him: normal force pushing up, weight pulling down, and tension pulling down.

The load has three forces on it: weight pulling down and two tension forces pulling up.

Sum of the forces on the load:

∑F = ma

2T - 480 N = 0

T = 240 N

Sum of the forces on the worker:

∑F = ma

N - 720 N - 240 N = 0

N = 960 N

So the pressure produced by the worker is:

P = F / A

P = 960 N / 320 cm²

P = 3 N/cm²

P = 30,000 Pa

The Moon phase described is the waxing gibbous phase, which occurs after the first quarter phase and before a full moon, with the majority of the illuminated side becoming increasingly visible.

The phase of the Moon depicted in the description corresponds to the waxing gibbous phase.

This phase occurs during the week after the first quarter phase, where more of the Moon's illuminated half becomes visible from Earth, leading up to a full moon.

At the waxing gibbous phase, the Moon has not yet reached the full moon stage where it is opposite the Sun and its entire illuminated side is visible from Earth.

The waxing gibbous Moon rises in the afternoon and is visible for most of the night, setting in the early morning hours.

Its visibility throughout the night can be particularly helpful for activities like taking a romantic stroll or returning from a late-night study session.

Answer:

150 millimeters

Explanation:

According to linear conversion of units;

1 cm is equivalent to 10 mm

Therefore, 15 cm will be equivalent to 150 mm

On the other hand;

1 Meter is equivalent 100 cm

Therefore; 15 cm will also be equivalent to 0.15 M

Hence;

15 cm = 150 mm = 0.15 m, and so forth

Answer:

The charge stored in a parallel plate capacitor is proportional to the potential, and capacitance across the plates.

Explanation:

The capacitance of a parallel plate capacitor is given by:

[tex]C=\frac{Q}{V}[/tex]

where

Q is the charge stored

V is the potential difference across the capacitor

Re-arranging the formula, we get

[tex]Q=CV[/tex]

From this expression, we see that the charge stored (Q) is proportional to both the potential (V) and the capacitance (C).

Answer:

The answers are potental and capacitance

Explanation:

5A. The current that flowing through the circuit with a lightbulb of 22Ω connected to a voltage source of 110V is 5A.

The key to solve this problem is using Ohm's Law equations V = I*R, where V is the voltage drop, I is the current that flow through the element and R its resistance.

Clear I from the equation above:

I = V/R

With V = 110V, and R(lightbulb) = 22Ω

I = 110V/22Ω = 5A

Explanation:

I hope me putting the answer instead of a paragraph helps yall<3

Valence electrons, which are located in the outermost shell of an atom, participate in the formation of chemical bonds with other atoms.

The electrons that are involved in bonding between atoms are known as 'valence electrons'. These electrons are situated in the outermost shell or energy level of an atom. Their role is extremely essential as they partake in the formation of chemical bonds with other atoms. For instance, in the bonding of two hydrogen atoms to form a hydrogen molecule (H2), each atom provides one electron to form a single covalent bond.

12,000 coils. The primary winding has 12,000 coils.

In order to solve this problem we have to use the relation for a transformer Vp/Vs = Np/Ns, where Vp is the voltage across the primary winding, Vs in the voltage across the secondary winding, Np is the numbers of coils in the primary winding, and Ns is the number of coils en the secondary winding.

With Vp = 350,000 V, Vs = 17,500 V, and Ns = 600 coils:

350,000 V/17,500 = Np / 600 coils

Np = (600 coils x 350,000 V) / 17,500 V

Np = 210,000,000/ 17,500 coils

Np = 12,000 coils

Answer:

ITS C

Explanation:

Answer:

The temperature of the system increases.

Explanation:

As we know that in adiabatic process the heat transferred to the system must be zero

now by first law of thermodynamics we know that

[tex]Q = \Delta U - W[/tex]

now we know that

Q = 0 (for adiabatic process)

now we have

[tex]\Delta U = W [/tex]

as we know that gas is compressed so the work is done on the gas which shows W is positive

So here change in internal energy must be positive which shows that temperature must be increased

so correct answer will be

The temperature of the system increases.

Answer:

Heat will flow from the tea into the air of the room

Explanation:

Heat Transfer

Answer:

Heat will flow from the tea into the air in the room

Explanation:

The sistem is going to find an equilibrium temperature for both elements.

As we have a small hot mass and a large cold mass, that temperature will be colder than the tea (and hotter than the air, but as the size of a cup is too small for a room, it will be almost equal to 24 Celsius)

Then the heat will 'leave' the tea.

The change in velocity at a specific moment is called Instantaneous acceleration. It is the acceleration at an exact instant as opposed to an average over a time period.

The change in velocity that occurs at a specific moment in time is known as Instantaneous acceleration. Acceleration is the rate at which velocity changes with time. In general, it is calculated as the change in velocity divided by the time over which the change occurred. In physics, when we say 'at a specific moment in time', we refer to an infinitesimally small interval of time. In this case, we are referring to the concept of instantaneous acceleration. It's the acceleration at a particular instant in time as opposed to an average over a time interval.

The change in velocity at a specific moment in time is known as instantaneous acceleration.

The change in velocity that occurs at a specific moment in time is known as the instantaneous acceleration.

Instantaneous acceleration is the rate of change of velocity at a specific instant in time.

It is found by taking the derivative of the velocity function with respect to time.

For example, if a car is accelerating from rest to a speed of 60 mph in 10 seconds, the instantaneous acceleration at the moment when the car reaches a speed of 30 mph would be different from the instantaneous acceleration at the moment when the car reaches a speed of 60 mph.

The examples of transverse waves are earthquake S waves and Radio waves with visible light and X- rays as the other examples.

Explanation:

The transverse waves are the waves which run perpendicular to direction of the wave. They oscillate at right angle to main wave. They form the crest and troughs which are alternate to each other. All the electromagnetic waves are simply transverse waves as the electric field generated waves are always perpendicular to the magnetic field generated waves.

 Answer:

The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.

There are three things that dictate how strong this field is:

1.How much kinetic energy you provide the wire

Answer is changed by pushing more current through the wire.

2. How permeable our magnetic rod is

Answer  is changed by picking a more magnetic media

3.How many little magnetic fields you generate to make the net, large magnetic field

Answer is changed by increasing the amount of turns of the wire. More turns, more little fields, strong big field

The strength of an electromagnet can be altered by increasing the electric current, adding more coils or windings to the solenoid, and incorporating a ferromagnetic core.

To change the strength of an electromagnet, there are several factors you can modify:

It's worth noting that using more windings increases the winding density, and this, along with a higher current, will increase the magnetic field strength.

Also, keep in mind that the limits to how strong you can make your magnet are the coil resistance and any material-related constraints, like the potential destruction of superconducting properties if the magnetic field is too strong.

Explanation:

Acceleration is change in velocity over change in time:

a = Δv / Δt

a = (10 m/s - 25 m/s) / (240 s - 0 s)

a = -0.0625 m/s²

So the car decelerates at 0.0625 m/s².

Explanation:

According to the Third Kepler’s Law of Planetary motion “The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.

Talking in general, this law states a relation between the orbital period [tex]T[/tex] of a body (moon, planet, satellite) orbiting a greater body in space with the size [tex]a[/tex] of its orbit.

This Law is originally expressed as follows:

[tex]T^{2}=\frac{4\pi^{2}}{GM}a^{3}[/tex]

Where;

[tex]G[/tex] is the Gravitational Constant

[tex]M=1.9(10)^{27}kg[/tex] is the mass of the massive (greater) body

[tex]a[/tex]  is the semimajor axis of the orbit of the smaller body

Answer:

formula

speed = distance / time

distance = speed x time

distance = 346 x 5

distance = 1730 m

The distance of the lightening strike would be 1730 m or 1.7 km

Explanation:

Answer:

1730m

Explanation:

Answer:

2.5 m/s

Explanation:

The velocity of the package relative to the ground = the velocity of the package relative to the helicopter + the velocity of the helicopter relative to the ground

v = 0 m/s + 2.5 m/s

v = 2.5 m/s

At the moment it is released, the package is rising at 2.5 m/s.

Final answer:

At the moment of release, the package dropped from the helicopter has an upward initial velocity relative to the ground of 2.5 m/s, equal to the helicopter's climbing velocity.

Explanation:

When a package is dropped from a helicopter that is climbing, the initial velocity of the package relative to the ground is the same as the velocity of the helicopter at that moment. Since the helicopter is climbing at a velocity of 2.5 m/s, the package will also have an initial velocity of 2.5 m/s upward relative to the ground. It is important to note that this is the initial velocity at the moment of release; the package will then be subject to gravitational acceleration which will affect its velocity as it falls.

Answer:

Condensation

Explanation:

Condensation is the process in which a gas turns into a liquid, by releasing heat. In such a process, heat is released from the gas to the environment, and the molecules of the gas become closer to each other, and they feel more the intermolecular forces between each other.

The processes that describe the different changes of phase of matter are:

- Melting: when a solid turns into a liquid, absorbing energy

- Evaporation: when a liquid turns into a gas, absorbing energy

- Condensation: when a gas turns into a liquid, releasing energy

- Freezing: when a liquid turns into a solid, releasing energy

- Sublimation: when a solid turns into a gas, absorbing energy

- Deposition: when a gas turns into a solid, releasing energy

Answer:

7.2 V

Explanation:

The three batteries are connected in series to the terminals of the phone: it means that they are connected along the same branch, so the current flowing through them is the same.

This also means that the potential difference across the phone will be equal to the sum of the voltages provided by each battery.

Here, the voltage provided by each battery is

V = 2.4 V

So, the overall voltage will be

V = 2.4 V + 2.4 V + 2.4 V = 7.2 V
