Label these parts on the wave below: Amplitude, Wavelength, Crest, Trough, Rest Position

Leviafan [203]

Answer:

Wavelength is the distance between from one crest to another crest or from one trough to another trough. The amplitude is the distance from the midpoint to the crest or trough. Crest is the highest point of the or a wave. Tough is the lowest point of the or a wave. Rest position is the position where it lies on the midpoint line.

Explanation:

I need a diagram to label these parts.

What is the mass of an object that requires a force of 182 N to accelerate at a rate of 13 m/s?

Inga [223]

Answer:

$m=14kg$

Explanation:

Hello.

In this case, since the force is defined in terms of the mass and acceleration by:

$F=m*a$

We can easily compute the mass by solving for it:

$m=\frac{F}{a}$

Whereas the force is 182 N (kg*m/s²) and the acceleration is 13 m/s², therefore, we obtain:

$m=\frac{182kg\frac{m}{s^2} }{13\frac{m}{s^2}}\\\\m=14kg$

Best regards.

If an amount of heat Q is needed to increase the temperature of a solid metal sphere of diameter D from 4°C to 7°C, the amount o

Hitman42 [59]

Answer:

Q = c M ΔT where c is the heat capacity and M the mass present

Q2 / Q1 = M2 / M1 since the other factors are the same

M = ρ V where ρ is the density

M = ρ Π (d / 2)^2 where d is the diameter of the sphere

M2 / M1 = (2 D/2)^2 / (D/2)^2 = 4

It will take 4Q heat to heat the second sphere

A man wishes to row the shortest possible distance from north to south across a river which is flowing at 2 km/hr from the east.

sweet-ann [11.9K]

From the diagram we have that

$sin\theta = \frac{2}{4}$

$\theta = sin^{-1} (\frac{1}{2})$

$\theta = 30\°$

Therefore the direction is 30° from east of south
