Answer:

Wave speed = 1.25 m/s

Explanation:

Given that the

wavelength = 0.25 m.

Frequency F = 5.0 Hz

The speed of a wave is the product of wave frequency and the wavelength. That is

V = F λ

Where

V = wave speed (m/s)

λ = wavelength (m).

F = frequency (Hz).

Using the formula above gives:

V = 0.25 × 5

V = 1.25 m/s

That 1.5 kg brick falls to the ground. What is the kinetic energy when the brick is moving at 26 m/s? Formula: Variables: Work w

Tresset [83]

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 1.5 \times {26}^{2} \\ = \frac{1}{2} \times 1.5 \times 676 \\ = 1.5 \times 338 \\ = 507$

We have the final answer as

A standard 1 kilogram weight is a cylinder 54.0 mm in height and 55.0 mm in diameter. what is the density of the material

denis-greek [22]

The radius of the cylinder is equal to half the diameter:

$r=\frac{d}{2}=\frac{55.0 mm}{2}=27.5 mm$

The volume of the cylinder is given by:

$V=\pi r^2 h=\pi (27.5 mm)^2 (54.0 mm)=1.28 \cdot 10^5 mm^3$

where h is the heigth of the cylinder. Converting into meters,

$V=1.28 \cdot 10^{-4} m^3$

And the density of the material will be given by the ratio between the mass and the volume:

$d=\frac{m}{V}=\frac{1 kg}{1.28 \cdot 10^{-4} m^3}=7812.5 kg/m^3$

Which theory of the origin of the moon would be most supported if the moon had an irregular shape, like an asteroid? impact theo

Fiesta28 [93]

<span>Its the impact theory.
It suggests that the moon resulted from the collision of two protoplanets, or embryonic worlds. One of those was the just-forming Earth, and the other was a Mars-size object called Theia. The moon then coalesced from the debris, thus giving it its irregular shape.</span>
