Answer:

Train B

Explanation:

Let's find each train's speed using the following formula.

s=\frac{d}{t}

where d is distance and t is time.

<u>Train A</u>

Train A travelled a distance of 120 kilometers in 3 hours.

s=\frac{d}{t}\\d=120 km\\t= 3hrs

Substitute the values into the formula and divide.

s=\frac{120km}{3hrs}\\

s= 40 km/hr

<u>Train B</u>

Train B travelled a distance of 180 kilometers in 4 hours.

s=\frac{d}{t}\\d=180 km\\t= 4hrs

Substitute the values into the formula and divide.

s=\frac{180km}{4 hrs}\\

s= 45 km/hr

45 kilometers per hour is greater than 40 kilometers per hour, so Train B travelled faster.

The gravitational force between two volleyball players is 3.3x10^-7.
Pepsi [2]

The distance of separation between the two masses is 0.927 m.

<h3>Gravitational force:</h3>

This is the force that exists between two masses in the universe.

To calculate the distance of separation of the masses, we use the formula below.

  • F = GMm/r².............. Equation 1

Where:

  • F = Gravitational force
  • m = First mass
  • M = Second mass
  • G = Universal constant
  • r = distance of seperation.

Make r the subject of the equation.

  • r = √(GMm/F)................... Equation 2

From the question,

Given:

  • F = 3.3×10⁻⁷ N
  • m = 61 kg
  • M = 75 kg
  • G = 6.69×10⁻¹¹ Nm²/kg²

Substitute these values into equation 2

  • r = √(61×75×6.69×10⁻¹¹)/(3.3×10⁻⁷)
  • r = 0.927 m

Hence, The distance of separation between the two masses is 0.927 m

during a dodge ball game a student throw a ball at another player what forces act on the ball as it flie through the air
olchik [2.2K]
Gravity acts to accelerate the ball downward, and air resistance acts in a way to slow the ball along it's instantaneous velocity (no matter which way it's moving air applies a force in the opposite direction)
