The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific

Find the gravitational force that Earth (mass = 5.97 × 10²⁴ kg) exerts on the moon (mass = 7.35 × 10²² kg) when the distance bet

alexandr402 [8]

Explanation:

mass of earth (m1)=5.97×10^24

mass of moon (m2)=7.35×10^22

distance between their center (d)= 3.84×10^8

G=6.67×10^-11

now,

gravitational force =(F)= G(m1×m2)/d²

6.67×10^-11(5.97×10^24×7.35×10^22)/(3.84×10^8)
19.84×10^19

6. An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speed of t

Ymorist [56]

Answer:

The distance away the center of the earthquake is 1083.24 km.

Explanation:

Given that,

Speed of transverse wave = 9.1\ km/s

Speed of longitudinal wave = 5.7 km/s

Time = 71 sec

We need to calculate the distance of transverse wave

Using formula of distance

$d=v\times t$

$d=9.1\times t$ ....(I)

The distance of longitudinal wave

$d=5.7\times (t+71)$ ....(II)

From the first equation

$t=\dfrac{d}{9.1}$

Put the value of t in equation (II)

$d =5.7\times(\dfrac{d}{9.1}+71)$

$\dfrac{9.1d-5.7d}{9.1}=71\times5.7$

$d0.3736=404.7$

$d =1083.24\ km$

Hence, The distance away the center of the earthquake is 1083.24 km.
