The weight of the bag of sugar in Newton on Earth is 13.34 N.
The weight of the bag of sugar in Newton on moon is 2.22 N.
The weight of the bag of sugar in Newton on Venus is 12.1 N
The mass of the bag of sugar is the same on the three locations and the value is 1.36 kg.
The given parameters;
- <em>weight of the sugar, w = 3 lb = 1.36 kg</em>
- <em>acceleration due to gravity on moon, g₁ = ¹/₆ x 9.81 = 1.635 m/s²</em>
- <em>acceleration due to gravity on venus, g₂ = 0.904 x 9.81 = 8.868 m/s²</em>
The weight of the bag of sugar in Newton on Earth is calculated as follows;
W = mg
W = 1.36 x 9.81 = 13.34 N
The weight of the bag of sugar in Newton on moon is calculated as follows;
W = 1.36 x 1.635
W = 2.22 N
The weight of the bag of sugar in Newton on Venus is calculated as follows;
W = 1.36 x 8.868
W = 12.1 N
The mass of the bag of sugar is the same on the three locations.

To solve the astronaut's problem it is necessary to quickly consider the conservation of the moment.
By definition we know that,
Initial Momentum = Final Momentum
Where,
Human mass
Tank mass
v is the initial and final velocity of each object
In the case of the initial part we know that it is in a state without movement with respect to the ship.
In the case of the final moment there is a speed injection thanks to the oxygen tank, then,
Re-arrange to find the final velocity for astronaut,
Replacing
The astronaut has 4 minutes of air and must travel 200 meters therefore,
Re-arrange to find the time,
<em>He/She will reach the spacecraft within the stipulated time</em>
Answer:
This is green light
Explanation:
According to the photoelectric effect, the maximum kinetic energy of an photoelectron is given by:
Here, E is the energy of the photon and W is the minimum energy required to remove an electron from the surface of the metal, W is defined as:
The Planck – Einstein relation states that the energy of a photon is equal to its frequency multiplied by the planck constant:
Recall that . Replacing (3) and (2) in (1):
Solving for :
This is green light
