Answer:
The correct answer is option B)
Explanation:
Considering the given question as -
The space shuttle is located exactly half way between the earth and the moon. Which statement is true regarding the gravitational pull on the shuttle? A) The moon pulls more on the shuttle. B) The earth pulls more on the shuttle. C) Both are equal due to equal distances. D) Both are equal due to the mass of the shuttle.
We know that gravitational pull (F) between any two bodies of mass and is given by -
F = where 'r' is the distance between the two bodies.
Let ,
: Mass of the earth
: Mass of the moon
m : Mass of the satellite
: Distance of satellite from earth
: Distance of satellite from moon
Given that =
Let ==r
Force on satellite by the earth is -
=
Force on satellite by the moon is -
=
∵ Mass of earth () > Mass of moon ()
∴ >
∴ The gravitational pull of earth on satellite is more than that of the moon.

The average speed of a cheetah that runs 140 meters in 5 seconds is calculated by dividing the distance by time, which equals 28 m/s.
To calculate the average speed of a cheetah running a distance of 140 meters in 5 seconds, we use the formula for average speed which is:
Average Speed = Distance / Time
Substituting the given values of distance and time in this equation, we get:
Average Speed = 140 meters / 5 seconds
Solving this, we obtain the average speed of the cheetah as 28 m/s.
The average speed is a scalar, meaning we do not include direction in the answer. For comparison purposes, the speed of a typical automobile might be around 15 m/s.

velocity?
Answer:
Emily's average speed is 6 mph and her average velocity is zero.
Explanation:
We can calculate the average speed as:
s = (s₁ + s₂) / 2 = (5 mph + 7 mph ) /2 = 12 mph / 2 = 6 mph
s: average speed
s₁: speed in the first 3 laps
s₂: speed in the second 3 laps
And we can calculate the average velocity as:
v = (df - di) / t = (0 m - 0 m) / t = 0 m / t = 0 m / s
v: average velocity
df: final displacement
di: initial displacement
t: time
As Emily is finally in the same place, it doesn't matter the time to finish the 6 laps, we know that the displacement is zero so the average velocity is zero too.

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.
Here,
Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.
Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.
P 1/V
PV = a constant
When the temperature of the gas is held constant.
Hence,
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
