As we presume that the fluid density is greater than the gas density based on common sense, the volume of the balloon decreases. The mass per unit volume is known as fluid density.
Greek letter stands in for and (rho). Mass per length squared, or M/L3, is the unit of measurement for density. Specific Weight vs. Weight Density: A fluid density, also known as specific density, is determined by dividing the fluid's weight by its volume. Weight per volume of a fluid is also referred to as weight density.
A mathematical term called "volume" describes how much three-dimensional space is occupied by an item or a closed surface. The measurement of volume is done in cubic units, like m3, cm3, in3, etc.

If the net force acting on an object is zero, then there <em>may be</em> no forces at all acting on it. If there ARE any, then they're <em>balanced</em>.
Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
Answer:
The answer is temperature lol
Explanation:

The correct answer is 9.45 kg.
The formula for calculating the density of an object is expressed as:
Density = mass / volume
Given :
Density = 150kg/m³
Volume of the sphere = negligible
r is the radius = 50/2 = 25cm = 0.25m
We can find the volume of the Styrofoam sphere by
=(4/3)πr³
Volume (V) = (4/3)*π*(0.25)³
Volume = 0.063 cm³
Now let us find the required mass:
Mass = density * volume
Mass = 150 * 0.063
Mass = 9.45 kg
Therefore, the maximum mass that can hang without sinking from a 50.0 cm -diameter Styrofoam sphere in water is 9.45 kg.
