A2 = 16 m^2

Explanation:

Application of Pascal's law:

F1/A1 = F2/A2

Given:

F1 = 50 N. A1 = 1 m^2

F2 = 800 N A2 = ?

A2 = (F2/F1)A1 = (800 N/50 N)(1 m^2)

= 16 m^2

In any given wave, when the frequency of the wave doubles (f = 2f), which of the following other changes would also take place?
Zanzabum

Answer:

The correct answer is -

B. The velocity would double (v = 2v).

C. The wavelength would be half (λ = λ/2).

Explanation:

A wave has a speed or velocity that is related to the wavelength of the wave and the frequency of the wave and this relationship can be represented by the following equation-

Wave velocity V = Wavelength (λ) * Frequency (f)

Frequency (f) = Velocity (V) / Wavelength(λ).

The frequency and wavelength are inversely proportional and frequency and velocity are directly proportional to each other.

So, if f = 2f then,

putting value in the formula,

2f = 2v/λ, which means, f = 2v and f = λ/2

when the frequency is doubled, the wavelength will be halved and velocity will be doubled.

A force is applied to a block to move it up a 30° incline. The incline is frictionless, the block is initially at rest, F= 65.0
muminat

Answer:

0.96 m, upward

Explanation:

\theta=30^{\circ}

F=65 N

M=5 kg

Initial velocity, u=0

t=0.550 s

Fcos\theta-Mgsin\theta=Ma

Where g=9.8 m/s^2

Substitute the values

65cos30-5\times 9.8sin30=5a

31.8=5a

a=\frac{31.8}{5}=6.36 m/s^2

S=ut+\frac{1}{2}at^2

S=0+\frac{1}{2}(6.36)(0.55)^2=0.96 m

Hence,the block moves upward because displacement is positive.
