First, begin by noting the SI prefixes. The meter is the base SI unit for distance.

The prefixes: Kilo = 10^3, Mega = 10^6, Giga = 10^9, Tera = 10^12

Given that the value is 1.5 × 10^11, the closest prefix is Giga (10^9).

Calculate:
1.5 × 10^{11} ÷ 10^{9} = 1.5 × 10^2 Gm = 150 Gm

To convert into kilometers, divide by 10^3 instead:

1.5 × 10^{11} ÷ 10^{3} = 1.5 × 10^{8} km

The loudness of a sound is inversely proportional to the square of your distance from the source of the sound. if your friend is
Yuliya22 [3333]

Define loudness as L, distance as d, and k as the variation constant. The appropriate equation representing the relationship is:
                    L = k / d^2
For Situation 1,
                    L1 = k / d1^2
For Situation 2,
                    L2 = k / (d1 / 4)^2
To have equal k, it follows that L2 = 16 L1.
Thus, the loudness your friend experiences is 16 times greater than yours.

Which of the following four circuit diagrams best represents the experiment described in this problem?
inna [3103]

There's an absence of circuit diagrams.  

Initially, this causes worry for a moment, until we remember that we have no understanding of the experiment mentioned in the problem either, rendering such worries unnecessary.

"if a stream flow measures 12 meters in 60 seconds, what is the stream's average rate of flow?"
Yuliya22 [3333]
Discharge refers to the volume of water flowing down a river or stream within a specific timeframe, typically measured in cubic feet per second or gallons per day. Generally, the discharge of a river is calculated by taking the product of the cross-sectional area of water in the channel and the average velocity of water at that section: discharge = area * velocity. In this instance, the result is 0.2 m/s.

Liam throws a water balloon horizontally at 8.2 m/s out of a window 18 m from the ground.
Yuliya22 [3333]

The time required for the water balloon to reach the ground is given as

h = \frac{1}{2} gt^2

Here we understand that

h = 18 m

g = 9.8 m/s^2

Now applying the earlier mentioned formula

18 = \frac{1}{2}*9.8* t^2

18 = 4.9 t^2

t = 1.92 s

Now in the same time frame, we can conclude the distance covered will be

d = v_x * t

d = 8.2 * 1.92 = 15.7 m

Thus, it will land at a distance of 15.7 m from where it started
