So many thinks the water wouldnt have as many waves it could result in no season and even an ice age. Nights would be darker. In result in the tides changing animals will be confused, some species rely on the tides for food and shelter. So without that it would cause a chain of mass extinction.

A tired physics professor can easily read the fine print of the financial page when the newspaper is held at arm's length, 61.5
leva [86]

Answer:

45.04 cm

Explanation:

The tired physics professor red easily at a distance of 26 cm

So v = 26 cm

And it is given that object distance that is u = 61.5 cm

There is relation between focal length object distance and image distance that is \frac{1}{f}=\frac{1}{v}-\frac{1}{u}

Here f =focal distance v = image distance and u = object distance

So \frac{1}{f}=\frac{1}{26}-\frac{1}{61.5}

So f=45.04 cm

Daisy walks across a force platform, and forces exerted by her foot during a step are recorded. The peak velocity reaction force
Len [333]

Answer:

(a). The resultant of these forces is 1216.55 N.

(b).  The direction of the resultant forces is 80.53°.

Explanation:

Given that,

First force = 1200 N

Second force = 200 N

(a). We need to calculate the resultant of these forces

Using cosine law

F=\sqrt{F_{1}^2+F_{2}^2+2F_{1}F_{2}\cos\theta}

Put the value into the formula

F=\sqrt{1200^2+200^2+2\times1200\times200\cos90}

F=\sqrt{1200^2+200^2}

F= 1216.55\ N

The resultant of these forces is 1216.55 N.

(b). We need to calculate the direction of the resultant forces

Using formula of direction

\tan\alpha=\dfrac{F_{1}}{F_{2}}

Put the value into the formula

\alpha=\tan^{-1}(\dfrac{1200}{200})

\alpha=80.53^{\circ}

Hence, (a). The resultant of these forces is 1216.55 N.

(b).  The direction of the resultant forces is 80.53°.

The displacement at any given time of an object is x = 6 sin 98t , where the symbols have their usual meanings. i). Proof that t
Fofino [41]

A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation, which are represented in the given function as 6 units and 98 rad/s respectively.

<h3>General wave equation for simple harmonic motion</h3>

y = A sinωt

where;

  • A is amplitude of the motion
  • ω is angular frequency

<h3>Amplitude of the oscillation</h3>

A = 6 units

<h3>Angular frequency of the wave</h3>

ω = 98 rad/s

A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation. Thus, the wave is executing simple harmonic motion.

A nautical mile is 6076 feet, and 1 knot is a unit of speed equal to 1 nautical mile/hour. How fast is a boat going 8 knots goin
mezya [45]

Answer:

The speed of the boat is equal to 13.50 ft/s.

Explanation:

given,

1  nautical mile = 6076 ft

1 knot = 1 nautical mile /hour

1 knot = 6076 ft/hr

speed of boat = 8 knots

 8 knots = 8 nautical mile /hour

               =8 \times \dfrac{6076\ ft}{1\nautical\ mile}\times \dfrac{1\ hour}{60\times 60\ s}

               = 13.50 ft/s

The speed of the boat is equal to 13.50 ft/s.
