kinematic eq.  d = Vi*t + 1/2a*[tex]t^{2}[/tex]

Explanation:

Vi=0

d=1/2 a*[tex]t^{2}[/tex]

d= 1/2(9.8)[tex]0.9^{2}[/tex]

d=3.969 m

The distance from which the object falls is 393.9 meters.

Given that, an object falls from a high building and hits the ground in 9.0 seconds and air resistance = 0

So the distance can be calculated by the formula given below.

[tex]s = vt + \dfrac{1}{2} at^2[/tex]

Where, [tex]s[/tex] is the distance in meters, [tex]t[/tex] is time (in seconds) taken by the object in motion, [tex]a[/tex] is the acceleration of the object in meter per second square and [tex]v[/tex] is  the final velocity in meter per second.

In this case, object falls from high building to the ground so the final velocity would be zero. Gravitational acceleration is -9.8 meter per second square.

Substituting the values in the above formula,

[tex]s = (9.0\times0) + \dfrac{1}{2}(-9.8\times(9.0)^2)\\s = 0 + (-9.8\times81\times0.5)\\s = 396.9 \;\rm m[/tex]

The distance from which the object falls is 393.9 meters.

Answer:

The horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

Explanation:

Displacement, d = 145 m

The top of a building at an angle of 28 degrees below the horizontal

We need to find the horizontal and vertical displacement.

For horizontal displacement,

[tex]D_x=d\cos\theta\\\\D_x=145\times \cos(28)\\\\D_x=128.02\ m[/tex]

For vertical displacement,

[tex]D_y=d\sin\theta\\\\D_y=145\times \sin(28)\\\\D_y=68.07\ m[/tex]

So, the horizontal and vertical displacement is 128.02 m and 68.07 m respectively.

Answer:

Earths shadow covering the moon would create a lunar eclipse.

Explanation:

because i just know

A lunar eclipse is occur when Earth’s shadow is covering the moon.

An eclipse happens when one astronomical body like Earth or moon blocks light from or to another.

A lunar eclipse is caused by Earth blocking sunlight from reaching the moon and causing a shadow across the lunar surface.

Sometimes when the Moon orbits Earth, the Moon moves between the Sun and Earth. When this happens, the Moon blocks the light of the Sun from reaching Earth. This causes an eclipse of the Sun, or a solar eclipse.

So the sled is moving towards the right of 15 N.

Answer:

The type of wave interaction occurred is destructive interference

Explanation:

Given that,

Max and Jimmy jump at same time.

Wave crest makes by Max and wave trough makes by Jimmy.

We need to find the type of wave interaction occurred

According to given data,

We know that,

If the wave crest and wave trough are interacted to each other then the interaction is destructive interference.

If the wave crest and wave trough are interacted with crest and trough then the interaction is constructive interference.

So, we can say that if the wave crest and wave trough are interacted to each other then the interaction is called destructive interference

Hence, The type of wave interaction occurred is destructive interference

Answer:

26897.3 m

Explanation:

1 km = 1000 m

1 cm = 0.01 m

so the calculation will be

25873 m + 1024 m + 0.03 m= 26897.3 m

The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.

As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,

(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)

1 kilometers = 1000 meters

1 meter =100 centimeters

(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)

                = 26897.03 centimeters

Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

Answer:

Explanation:

A parallel circuit, is one which the conductors leading into the bulbs are joined together on one side of the bulbs, and the conductors coming out of the bulbs are joined together on the other side of the bulb

The correct arrangement, advantages, lamp and resistance values are;

The reason the above values are correct are as follows:

(i) From the diagram attached, the lamps are arrange in parallel

This is so because, each lamp is directly connected across the terminals of the the voltage source

(ii) The advantages of the bulbs arranges in parallel are;

(iii) The brightness of the lamp is given by the power of the lamp

The lamp with the highest wattage, or power glows the most

Power, P = Voltage, V × Current, I

The power for lamp A, [tex]P_A[/tex] = 60 V × 3 A = 180 W

The power for lamp B, [tex]P_B[/tex] = 60 V × 4 A = 240 W

The power for lamp C, [tex]P_C[/tex] = 60 V × 5 A = 300 W (Brightest)

The power for lamp D, [tex]P_D[/tex] = 60 V × 3 A = 180 W

Therefore, lamp C has the highest power and glows the brightest

(iv) The total resistance is given by the voltage, divided by the total current

Total current, I = 3 A + 4 A + 5 A + 3 A = 15 A

[tex]Total \ resistance, \ R_{tot} = \dfrac{V}{I_{tot}}[/tex]

Therefore;

[tex]Total \ resistance, \ R_{tot} = \dfrac{60 \, V}{15 \, A }}=4 \, \Omega[/tex]

The total resistance, R = 4 Ω
