7.7 m/s

1st determine you subject slade to you have a mass of 15 kg being subjected to a force of 180N

so.

180N/15kg=180(kg m)/s^2/15kg=12 ms^2

now determine how long u pushed it

d=0.5 A T^2

sutable the known values getting

2.5 m = 0.5 12 ms^2 T^2

2.5m= 0.6 ms^2 T^2

0.41667 s^2=T^2

0.645497224s=T

the velocity multiply the time by the acceleration giving

0.645497224 s 12 ms^2 =7.745966692 ms.

after rounding the 2 significant u get 7.7 ms

Answer:

the crest of one wave to the crest of the next wave

Explanation:

In order to determine the wavelength, you must know the  crest of one wave to the crest of the next wave

Wavelength  is the distance between identical points (adjacent crust ) in the adjacent cycle of a waveform propagated in space or along wire .

wavelength can be determined by two methods

1) distance between crest and trough of that wave

2) distance between  crest of one wave to the crest of the next wave or

distance between  trough of one wave to the trough of the next wave

so , the correct answer will be d)the crest of one wave to the crest of the next wave

Answer:

The box gains 3200 J of kinect energy.

Explanation:

Kinect energy is the energy of an object has because of its motion. Almost anything that has mass and it's in motion has kinect energy. Examples:

Also known as the principle of work and kinect energy, it states that the work done by all forces acting upon an object equals the change of its kinect energy.

For example, if you pull a box, then you're exerting a force on it and it moves forward. Since the box has mass and it's in motion, you have changed its kinect energy.

Solution:

Write the data down:

[tex]\bullet \quad \mathsf{m=50\,kg}\\\\\bullet \quad \mathsf{F=400\,N}\\\\\bullet \quad \mathsf{d=8\,m}[/tex]

Apply work energy theorem:

[tex]\mathsf{W}= \Delta\mathsf{K}[/tex]

The amount work done equals the change of kinect energy:

[tex]\mathsf{W}=\mathsf{K-K_o}[/tex]

Since the block is at rest at the beginning, so it has zero initial kinect energy:

[tex]\mathsf{W}=\mathsf{K-0}\\\\\\\mathsf{W}=\mathsf{K}[/tex]

Now, apply the formula for work to the left hand side of the equation:

[tex]\mathsf{F\cdot d}=\mathsf{K}\\\\\\\mathsf{400\cdot 8}=\mathsf{K}\\\\\\\therefore \boxed{\mathsf{K=3200\,J}}[/tex]

Conclusion: the box has gained 3200 J of kinect energy.

→ Uses of Convex Mirror

• Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings.

• They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is a lack of visibility.

• They are also used in some automated teller machines as a handy security feature that allow user to see what all is happening behind them.

• They are used in passenger side mirror on a car and somewhere it is labelled as “objects in mirror are closer than they appear” to warn the driver.

→ Uses of concave mirror :

• Head mirrors

• Shaving mirrors

• Headlights

• Ophthalmoscope (optical instrument)

• Solar furnaces

• Astronomical telescopes

The size and aperture of the telescopes determine its ability to gather light

and reveal details.

A) Observatory X can detect dimmer stars and Observatory Y reveals more

details.

Reasons:

The benefits of using several small telescopes included the production

high resolution images of bright objects such as binary stars that reveal

more details similar to a telescope with a very large aperture, with a

process known as interferometry, through which a star's diameter can be

determined.

The benefit of a large telescope is its ability to gather light from a source,

thereby making possible to detect a dim light source, such as dimmer

stars.

Therefore;

The single large telescope in observatory X can detect dimmer stars while

the interferometer consisting of five 10-meter telescopes, spread out over a

region 100 meters across can see more detail in its images.

The correct option is; A) Observatory X can detect dimmer stars and

Observatory Y reveals more details.

Answer:

Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method. Often taught in chemistry or other science classes, this method is known for its simplicity and accuracy.

Explanation:

Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.

Shortest distance between two point are called as displacement, or we can say that when a body moves between two points the total  lengths between two points are called as distance but the shortest distance between two point is called as displacement. Displacement is measured in meter and it is a vector quantity.  Displacement may became zero but distance never became zero.

In above problem we cam say that in a race car start form a point and reaches at the same point then it's displacement is zero because  there is no shortest distance. Displacement is measured in meter and it is a vector quantity.  Displacement may became zero but distance never became zero.

This question involves the concepts of Pythagora's Theorem and derivatives.

The plane's distance is increasing at a rate of "105.6 ft/" (OR) "72 mph".

First, we will write an expression for the distance between the person and the plane in terms of time. For that purpose, we will use Pythagora's Theorem. Here, the altitude will act as perpendicular, the horizontal distance on the ground will be the base, and the straight line distance between the plane and the person will be the hypotenuse.

[tex]Hyp^2 = Base^2+Perp^2\\s^2 = (vt)^2+(32000\ ft)^2\\s=\sqrt{(vt)^2+(32000)^2}[/tex]

where,

s = plane's distance from the person

v = horizontal speedof the plane = [tex](120\ mph)(\frac{1.47\ ft/s}{1\ mph})[/tex] = 176 ft/s

t = time

Therefore,

[tex]s=\sqrt{(176t)^2+(32000)^2}[/tex]

Taking the derivative with respect to time:

[tex]\\\\\frac{ds}{dt} = \frac{1}{2}\frac{(2t)(176)^2}{\sqrt{(176t)^2+(32000)^2}}\\\\\frac{ds}{dt} = \frac{61952\ t}{2s}[/tex]

where,

[tex]\frac{ds}{dt}[/tex] = rate at which plane's distance is increasing from the person = ?

s = distance = [tex]\sqrt{(24000\ ft)^2+(32000\ ft)^2} = 40000\ ft[/tex]

t = time = [tex]\frac{horizontal\ distance}{v} = \frac{24000\ ft}{176\ ft/s} = 136.36\ s[/tex]

Substituting these values in the equation, we get:

[tex]\frac{ds}{dt}=\frac{(61952)(136.36)}{(2)(40000)}[/tex]

[tex]\frac{ds}{dt}=105.6\ ft/s = 72\ mph[/tex]
