Answer:
The linear density of the wire is 0.314 g/m.
Explanation:
It is given that,
Acceleration,
Mass of the ball, m = 112 gm
Speed of the transverse wave, v = 44.4 m/s
The speed of the transverse wave is given by :
Where
T = tension in the wire
= mass per unit length
or
So, the linear density of the wire is 0.314 g/m. Hence, this is the required solution.
Answer:
When equal and opposite forces meet each other, it results in motion and they would repel away from each other, causing the asteroid to be sent away from the earth.
Explanation:
Newton's Third Law states that every action has an equal and opposite reaction.
A. 0.25 terabytes
b. 2.5e + 17
Answer:
Its gravity potential energy is 39,240 J
Explanation:
The gravity potential energy of a body on the earth's surface is the energy a body under the influence of gravity possesses by virtue of its elevation from the surface of the earth.
We can calculate the GPE using this formula
from the problem given, we have m= mass= 20 kg
g = gravitational constant = 9.81m/s2
height = 200m
Hence, Its gravity potential energy is 39,240 J
A 52-newton tension force pulls down on the branch, and a 52-newton tension force pulls up on the bird feeder.
What is tension ?
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
Tension is the opposite of compression force. All the objects that are present in contact with each other exert a force on each other. The best example of a tension force can be seen while pulling a rope. When a pull force is applied to the rope, a significant amount of tension gets built.
