I don’t know just needed points im sorry
Answer:
<em>The force exerted by each string is 25 N</em>
Explanation:
<u>Net Force</u>
The net force is the vector sum of forces acting on a body. The net force is a single force that represents the effect of the original forces on the body's motion. It gives the particle the same acceleration as all those actual forces together as described by Newton's second law of motion.
The picture described in the problem is hanging at rest supported by two vertical strings. This means that the net force acting on it is zero.
Assume the magnitude of each of these equal forces is F, and the picture has a weight of W=50 N, thus the net force is:
F + F - W
The positive signs indicate an upwards direction and the negative sign means a downwards direction. Since the net force is zero:
F + F - W = 0
2F = W
F = W/2 = 50 N/2
F = 25 N
The force exerted by each string is 25 N
This is false. The reaction force can be determined.
Explanation:
The net force along the horizontal direction is
where f is the frictional force. We can find the frictional force by looking at the vertical forces acting on the couch:
From the definition of frictional force,
Therefore, the net force on the couch is
Wireless sensor networks
Explanation:
Networks of interconnected wireless devices that are embedded into the physical environment to provide measurements of many points over a large spaces are called Wireless sensor networks.
They are very useful in obtaining real-time data and information about every day life.
- The internet of things greatly relies on the use of wireless sensor networks in devices and gadgets to better and improve life.
- They are constantly in use by various organizations and bodies.
- Wireless sensor networks can be designed to collect specific scientific data or even more.
