Answer:

87.375 Acellus

Explanation:

Answer:

v = 102 m/s

Explanation:

Given that,

The frequency of a wave, f = 60 Hz

Wavelength = 1.7 m

We need to find the speed of this wave. The formula for the speed of a wave is given by

[tex]v=f\lambda[/tex]

Substitute all the values,

[tex]v=60\times 1.7\\\\v=102\ m/s[/tex]

So, the speed of the wave is equal to 102 m/s.

Genes are located in the CHROMOSOME

Explanation:

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

The energy of a single photon at the transmitted frequency is

A)3.55 × 10^(-28)J/photon

Energy of photon can be rewritten as

E=hv,

Where, h is planck's constant  

λ is the wavelength of photon  

Where f is the frequency of photon  

Thus, the energy of a single photon at the transmitted frequency obtained by using the formula, Energy (E) is equal to Planck's constant (h) times the frequency.

E=6.63×10^(-34)× 535×10^3

E =3.55 × 10^(-28) (J)

Photon energy doesn't depend on the power of radio station

Explanation:

Answer:

Approximately [tex]4.2 \times 10^{2}\; \rm W[/tex] on average in the vertical direction (assuming that [tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex].)

Explanation:

Vertical displacement of this student in [tex]6\; \rm s[/tex]: [tex]36 \times 16\; \rm cm = 36 \times (0.16\; \rm m) = 5.76\; \rm m[/tex].

Average vertical velocity of this student: [tex]v = \displaystyle \frac{5.76\; \rm m}{6\; \rm s} = 0.96\; \rm m \cdot s^{-1}[/tex].

The average vertical force that this student exerts on the ground would be equal to the weight of this student:

[tex]F = W = m \cdot g = 45\; \rm kg \times 9.8\; \rm N \cdot kg^{-1} = 441\; \rm N[/tex].

The average power of this student in the vertical direction is equal to the product of the force and velocity of this student in that direction:

[tex]P = F \cdot v = 441\; \rm N \times 0.96\; \rm m \cdot s^{-1} \approx 4.2\times 10^{2}\; \rm W[/tex].

Answer:

v = 8.12 m/s

Explanation:

The centripetal acceleration of the yo-yo is given by the following formula:

[tex]a_c = \frac{v^2}{r}\\\\v^2 = a_cr\\v = \sqrt{a_cr}[/tex]

where,

v = tangential speed = ?

ac = centripetal acceleration = 200 m/s²

r = radius = length of string = 0.33 m

Therefore, using the given values in the formula, we get:

[tex]v = \sqrt{(200\ m/^2)(0.33\ m)}[/tex]

v = 8.12 m/s

Amplitude: 30 cm; wavelength 110cm.

Answer:

the type of wave

Explanation:

Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.

Answer: B. Objects are exposed to X-rays, which either pass through or are

absorbed by the objects.

C. A silicon chip releases electrons by the photoelectric effect,

Explanation:

Answer:

F = 45 KN = 45000 N

Explanation:

Considering the downward direction as the positive direction:

[tex]P = P_1 - P_2[/tex]

where,

P = Resultant Pressure = ?

P₁ = Atmospheric Pressure = 100 KPa

P₂ = Pressure inside the can = 70000 Pa = 70 KPa

Therefore,

[tex]P = 100\ KPa - 70\ KPa\\P = 30\ KPa[/tex]

Now the resultant force will be given as:

[tex]F = PA[/tex]

where,

F = resultant force = ?

A = Area of side of can = 1.5 m²

Therefore,

[tex]F = (30\ KPa)(1.5\ m^2)\\[/tex]

F = 45 KN

Answer:

If the velocity and acceleration are in the same direction (both have the same sign - both positive or both negative) the object is speeding up. If the velocity and acceleration are in opposite directions (they have opposite signs), the object is slowing down.

Answer:

c) It gets positively charged

Explanation:

If an electrically neutral body is loaded with protons so it gets positively charged because proton has positive charge. When the protons is added to the neutral body, it can't remain neutral because the quantity of positive charges increases in the nucleus and it gets positively charged while on the other hand, the atom from which protons are taken will acquire negative charge due to presence of more number of electrons and we know that electrons has negative charge.

Explanation:

22. The energy of an electromagnetic wave and it's frequency are related by the following equation:

E = hf

Where:

E => is the energy

h => is the Planck's constant

f => is the frequency

From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.

23. Gamma ray and radio wave are both electromagnetic waves. All electromagnetic waves has a constant speed of 3×10⁸ m/s in space.
