Answer:
The net force is 20N in the direction of the 80N force.
Explanation:
The net force is the resultant force acting on a body. This force is that singular force that will have the same magnitude and effect as the network of forces on a body.
In this problem:
Force 1 = 80N
Force 2 = 60N
Net force = Force 1 - Force 2
Net force = 80N - 60N
Net force = 20N
The net force is 20N in the direction of the 80N force.
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
Answer:
Direction of the electric force acting on the proton after it enters the electric field is along the positive y-axis.
Explanation:
In an electrical field electrical field lines goes from positive to negative. Therefore, electrical force vector is on exactly the same way with electrical field lines for a proton. Which means if the electrical field directed along the positive y-axis, electrical force for proton will be on the same way.
Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.
