Is it kinetic or potential energy Or frequency and wavelength
The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.
<h3>What is momentum?</h3>
Momentum can be defined as the product of mass and velocity. The S.I unit of momentum is kgm/s.
The initial momentum of the boy can be calculated using the formula below.
Formula:
Where:
- M = Initial momentum of the boy
From the question,
Given:
- M = mass of the boy = 60 kg
- U = Initial velocity of the boy = 0 m/s (at rest)
Substitute these values into equation 1
Hence, The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.

Answer: 204 L
Explanation:
According to ideal gas equation:
P = pressure of gas = 0.262 atm
V = Volume of gas = ?
n = number of moles = 
R = gas constant =
T =temperature =
Thus volume occupied by 11.7 g of Helium in a balloon is 204L
