If an object is moving at 5m/s north and an balanced force is acting on it, it will continue to move at that same velocity.

The resultant force with the largest magnitude will be created by an angle between these forces.  0 degrees.

In this case, the result is P/2 and the two forces are P.The angle of two identical pressures is 151.04 degrees after squaring both sides.when there is no angle among two forces

If two forces are acting toward the same direction, their combined effect will be greatest.In this instance, its force will be straightforward—just the arithmetic total of the forces.The angle between the forces in this situation is 0°.

Answer:

Atlanta is at 596.0 km from the house.

Explanation:

The distance between Atlanta and the house can be found using the following equation:

\( v = \frac{d}{t} \)   (1)

Where:

v: is the speed = 80 km/h

t: is the time = 7.45 h

By solving equation (1) for d and entering the above values we have:

\( d = v*t = 80 km/h*7.45 h = 596.0 km = 596000 m \)

Therefore, Atlanta is at 596.0 km from the house.

A blackbody spectrum of temperature 900 Kelvin has been simulated. The peak wavelength in nanometers of an object of that temperature is determined to be nanometers. The intensity of the blackbody radiation at a given temperature and wavelength can be determined using Planck's law.

Planck's law, which describes the intensity of blackbody radiation, is given byI(λ) = 2hc²λ⁻⁵[exp(hc/λkT) - 1]⁻¹Where c = speed of light, h = Planck's constant, k = Boltzmann constant, T = temperatureλ = wavelength of lightI (λ) = spectral radiant intensity expressed in watts per square metre per unit wavelength.

Simulating the blackbody spectrum for a temperature of 900 K:

Using the equation for peak wavelength λ_max = 2897/T nm, where T = 900 KTherefore,λ_max = 2897/900λ_max = 3.22 µm or 3220 nm.

The emissive intensity of the object (the amount of power emitted per unit area) is given asI = σT⁴, where σ is the Stefan-Boltzmann constant.

Therefore,I = σT⁴ = 5.67 × 10⁻⁸ × (900)⁴W/m²= ×10 W/m².

Hence, the emissive intensity of the object is ×10 W/m².

The type of light that best illustrates the photoelectric effect is (c) ultraviolet light. Hence, the correct answer is option c).

Photoelectric effect refers to the emission of electrons from a metallic surface when a light of suitable frequency shines on the surface of the metal. The phenomenon, first noticed by Heinrich Hertz in 1887, was explained in 1905 by Albert Einstein when he used Planck's hypothesis to illustrate that light energy is carried in discrete quantized packets to describe the photoelectric effect.

In relation to photoelectric effect, the type of light that best illustrates it is ultraviolet light. This is because ultraviolet light has a high enough frequency to remove electrons from the metal surface. As a result, electrons that absorb photons with enough energy from the ultraviolet region of the electromagnetic spectrum will be ejected from the metal, causing the photoelectric effect, and producing an electric current.

When light is shone on a metallic surface, an electric current is produced, which is called the photoelectric effect. The photoelectric effect is caused by the emission of electrons from a metal surface that is exposed to a light of suitable frequency. The energy of the electrons depends on the frequency of the light, and the intensity of the light determines the number of electrons ejected from the surface.

The time constant of the circuit can be determined from the formula τ = RC. The values given in the question are R = 4.00 MΩ and C = 3.00 µF. Thus, the time constant is given as:τ = RC = (4.00 × 10^6 Ω) × (3.00 × 10^-6 F) = 12 secondsb. The current in the circuit can be found by using Ohm’s law, which states that I = V/R, where V is the voltage across the circuit.

The voltage across the circuit is 12.0 V, so the current is given as:I = V/R = (12.0 V)/(4.00 MΩ) = 3.00 µAThe charge on the capacitor as a function of time can be found using the formula Q = Qmax (1 - e^(-t/τ)), where Qmax is the maximum charge that can be stored by the capacitor. The maximum charge can be found using the formula Qmax = CV, where V is the voltage across the capacitor.

The voltage across the capacitor is the same as the voltage across the circuit, which is 12.0 V. Thus, the maximum charge that can be stored by the capacitor is:Qmax = CV = (3.00 × 10^-6 F) × (12.0 V) = 36 µCThe charge on the capacitor as a function of time is given as:Q = Qmax (1 - e^(-t/τ)) = (36 µC) (1 - e^(-t/12)).

Answer:

Height h = 37.8 m

Explanation:

Given :

Velocity of car (v) = 98 km / h

Acceleration of gravity = 9.8 m/s²

Computation:

Acceleration of gravity = 9.8 m/s²

Acceleration of gravity = (98)(1,000 m / 3,600 s)

Acceleration of gravity = 27.22 m/s

By using law of conservation of energy ;

(1/2)mv² = mgh

h = v² / 2g

h = 27.22² / 2(9.8)

Height h = 37.8 m

The height from which the car would have to be  dropped to have the same kinetic energy is 37.81 meters.

Given the following data:

To find the height from which the car would have to be  dropped to have the same kinetic energy:

First of all, we would convert the value of velocity in km/h to m/s.

Conversion:

\(98 = \frac{98}{3600} \times 1000 = 27.22 \;m/s\)

Applying the law of conservation of energy:

\(P.E = K.E\\\\mgh = \frac{1}{2} mv^2\\\\gh = \frac{1}{2}v^2\\\\h= \frac{v^2}{2g}\)

Substituting the given parameters into the formula, we have;

\(h = \frac{27.22^2}{2\times 9.8} \\\\h=\frac{741.05}{19.6}\)

According to Freud's theory of psychosexual development, identification refers to a process in which a child models their behavior, attitudes, and personality characteristics after someone of the same sex, usually a parent or caregiver.

In other words, the child identifies with and internalizes the traits and values of the person they see as a role model. Identification plays a crucial role in the formation of gender identity, as the child learns what it means to be a boy or girl based on the behaviors and attitudes they observe from their same-sex parent or caregiver.

This process is believed to occur during the phallic stage of psychosexual development, which occurs between the ages of 3 and 6 years old.During this stage, the child's focus is on their genitalia and they begin to develop a sense of gender identity.

They also experience the Oedipus or Electra complex, which is a desire to possess the opposite-sex parent and a fear of retaliation from the same-sex parent. The child resolves this conflict by identifying with the same-sex parent and adopting their gender role as their own.

This process is essential for the child's development of a healthy sense of self and their ability to navigate relationships with others.

\(= (I\alpha )/R\)

So since there is no slipping, whatever is the acceleration of the block is the acceleration of the cord. And that acceleration will be the linear acceleration of the this linear acceleration of the pulley.

So let's just assume Ta. Is greater than Tb.

Answer:

the magnitude of the displacement after 5s is 137.31 m.

Explanation:

Given;

initial velocity of the projectile, u = 60 m/s

angle of projection, θ = 60°

time of motion, t = 5s

the vertical component of the velocity, \(u_y= u\ sin \theta = 60sin(60^0)\)

The magnitude of the displacement after 5s is calculated as;

\(h = u_yt -\frac{1}{2} gt^2\\\\h = 60sin (60^0)\times 5 - \frac{1}{2} (9.8)(5)^2\\\\h = 259.81-122.5\\\\h = 137.31 \ m\)

Therefore, the magnitude of the displacement after 5s is 137.31 m.
