How do mass and energy affect the acceleration of a rocket

1 answer:

Alona [7]3 years ago

8 0

Answer:

Factors Affecting a Rocket’s Acceleration. The greater the exhaust velocity of the gases relative to the rocket, the greater the acceleration. The faster the rocket burns its fuel, the greater its acceleration. The smaller the rocket’s mass (all other factors being the same), the greater the acceleration.

A large helium filled balloon is used as the center piece for a graduation party. The balloon alone has a mass of 222 kg and it

inn [45]

Answer:

The buoyant force is 3778.8 N in upward.

Explanation:

Given that,

Mass of balloon = 222 Kg

Volume = 328 m³

Density of air = 1.20 kg/m³

Density of helium = 0.179 kg/m³

We need to calculate the buoyant force acting

Using formula of buoyant force

$F_{b}=\rho_{air}\times V_{b}\times g$

Where, $\rho_{air}$ = density of air

V = Volume of balloon

g = acceleration due to gravity

Put the value into the formula

$F_{b}=1.20\times321\times9.81$

$F_{b}=3778.8\ N$

This buoyant force is in upward direction.

Hence, The buoyant force is 3778.8 N in upward.
