Answer:

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:

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.

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.

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

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]

When there are two or more electrical devices in a circuit with an energy source, there are a couple of basic ways by which we connect them. They can either be connected in series or parallel

[tex]\huge\bold\green{Answer:-}[/tex]

A series circuit has only one path for electricity to flow from one point to another. The amount of electricity in the circuit is consistent throughout any component in the circuit. When electricity flows through a series circuit, its rate of flow (speed) will never fluctuate. The total resistance of a series circuit equals the sum of individual resistances. The more resistors that a series circuit has, the more difficult it is for electrons to flow.

A parallel circuit has multiple paths for electricity to flow from one point to another. According to website All About Circuits, “all components are connected between the same set of electrically common points.” Often, resistors and sources will be connected between two sets of electrically common points. In a parallel circuit, electricity can flow in multiple directions horizontally and vertically. The components of a parallel circuit will have the same voltage across their ends and will have identical polarities.
