A balloon contains helium with a mass of 0.00296 g. What is the volume of helium in the balloon? (Note: Helium’s density is 0.00

001663 g/cm3.) Volume: 0.00296g/0.00001663g/cm^3 = 177.991581cm^3

Answer:

178 cm3

Explanation:

From definition of density, it is mass per unit volume of an object, expressed as density=mass/volume and making volume the subject of the above formula we have volume= mass/density and substituting 0.00296 g for mass and 0.00001663 g/cm3 for density then we have

Volume=0.00296/0.00001663

Volume is approximately 178 cm3

ale4655 [162]
<span>An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left.

(1)  22 N to the right
(2) 13 N to the left.

magnitude = 22 - 13
magnitude = 9

Direction would be to the right.

So magnitude is 9N direction to the right.</span>

The acceleration due to gravity on Earth is 9. 8 m/s2. What is the weight of a 75 kg person on Earth? 9. 8 N 75 N 85 N 735 N.
Illusion [34]

The weight of a 75 kg person on Earth, which has an acceleration due to gravity of 9.8m/s², is 735N.

CALCULATE WEIGHT:

Weight is a force, hence, measured in Newton. It is a function of an object's mass in relation to gravity.

Weight of an object can be calculated using the following formula:

W = mg

Where;

  • W = weight (N)
  • m = mass (kg)
  • g = acceleration due to gravity (m/s²)

The weight of the person in this question can be calculated as follows:

W = 75 × 9.8

W = 735N

Therefore, the weight of a 75 kg person on Earth, which has an acceleration due to gravity of 9.8m/s², is 735N.

How do you find the change in potential energy
ratelena [41]

P.E = mgh

This is the formula for potential energy.

This is where m is mass, g is the acceleration due to gravity, and h is height.

All you have to do is multiply all these numbers together.
