An eagle carrying a trout flies above a lake along a horizontal path. The eagle drops the trout from a height of 6.1 m. The fish travels 7.9 m horizontally before hitting the water.What is the velocity of the eagle? Round your answer to the nearest tenth.
m/s
Answers
Answer:
7.1 m/s
Explanation:
First, find the time it takes for the fish to reach the water.
Given in the y direction:
Δy = 6.1 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
6.1 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.12 s
Next, find the velocity needed to travel 7.9 m in that time.
Given in the x direction:
Δx = 7.9 m
a = 0 m/s²
t = 1.12 s
Find: v₀
Δx = v₀ t + ½ at²
7.9 m = v₀ (1.12 s) + ½ (0 m/s²) (1.12 s)²
v₀ = 7.1 m/s
Answer:
7.1m/s

Answers
Answer: A) because forces are what stop and start motion
Explanation:
From Newton's first law, an object tends to stay in state of rest or motion unless acted upon by an unbalanced external force. This is also known law of inertia. This is because a force can stop or start a motion. A force cause body to accelerate to decelerate otherwise the body continues with constant speed.
An object in motion stays in motion unless acted on by an unbalanced force A) because forces are what stop and start motion
Further explanation
In Newton's first law, it is stated that if the resultant force acts on an object of magnitude is zero, it can be formulated:
then the object tends to defend itself from its state.
or can be stated:
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass that move translatively, the object will maintain its linear velocity
Forces are balanced when all the forces act upon an object balance with each other
Forces are unbalanced when there is an individual force that is not being balanced by another force
So the object in balanced forces:
- 1. object at rest v = 0, a = 0
- 2. object at motion v ≠0, a = 0
Let see the answer choices
- A) because forces are what stop and start motion
If there is an unbalanced force, the object will tend to move from the rest position or the object changes its state of motion.
Statement is true
- B) because balanced forces can not exist in nature
Balanced forces can exist in nature for example. For example a person standing on the floor. There are two forces. The force of gravity and the floor for upward force, thus the person maintains its state (rest motion). So this condition is called a state of balance or balance.
Statement is false
- C) because motion is the inherent state of all matter
All matter is not only in a state of movement but also in a position of rest
Statement is false
- D) because motion, once begun, continues to accelerate
motion of object can accelerate or decelerate
Statement is false

Parallelism is a property shown by the rails of a railway track.
Option B
Explanation:
Parallelism is the property of the lines which do not meet in a plane, those lines which "do not intersect or touch each other" are parallel to each other.
In the given example, railway lines of railway track are said to be parallel since they are at an equal distance to each point so that the wheels of the train be on track. Since these railway lines do not meet each other even at infinity, they are said to be parallel.
Answer:
parallelism
Explanation:
i took the quiz on Edge 2020 and got it right i promise :)
also this question is mostly based on common sense because if two lines will never intersect they are parallel and train tracks will never intersect so they are also parallel and they only word there that has parallel in it is parallelism so the answer has to be parallelism.

At the times when the person is not moving up or down, the tension in
the rope is 500N. At those moments, the forces on the person consist
of 500N downward due to gravity and 500N upward due to the tension in
the rope, and with the forces balanced, the person just hangs there and
doesn't accelerate up or down.
At the times when the person is actually climbing, that is, hauling himself
upward, the tension in the rope must be greater than 500N. At those moments,
the net force on the person is upward, and the person's body accelerates upward.
the tension of a person weighing 500 pounds on a rope will make the rope break little by little,untill it gets to the point the rope snaps.

The force of gravity between two objects always involves the product of
both of their masses.
"Weight" is the force of gravity between a planet and an object on its surface,
so it depends on both masses.
When a rock, a space probe, or an astronaut goes to a different planet, its/his
mass doesn't change, but the mass of the body they're standing on is different.
So the weight of the rock or the astronaut is different from what it is on Earth.
So, this formula clearly depicts that Weight of any object depends on mass of that object as well as on the gravitational acceleration. So, the lesser gravitational acceleration on Moon makes an object weigh lighter on Moon than on Earth. Similarly it is true for different planets also.
