The mass of an object can neither be change but the weight of the object can be changed.
<h3>
What causes a decrease in an object weight?</h3>
The weight of the body or of an object can be changed if the body is placed farther away from the earth or placed in the planet which is far away from the earth's gravitational field, so the force of gravity on the object will change. However the mass of the body or mass of the object will remains the same regardless of whether the object is on Earth, in outer space, or on the Moon. By doing so the weight of the object or body will change but the mass remains the same.
So we can conclude that: The mass of an object can neither be change but the weight of the object can be changed.

Answer:
it Farther then it seems
Explanation:cause it value
<span>a) All the 26m should be used to bent into a square to maximize the total area (= 42.25 m2)
b) 1.4136m should be bent into a square and the rest (= 24.586m) should be bent into an equilateral triangle to minimize the total area (= 29.0835m2)</span>
Yes, all waves can be distorted, deflected, or changed
<span>Waves are a means by which energy travels. Many different particles move in waves. </span>All waves can be changed through interference with waves of similar wavelengths.
Answer:
T = mg/6
Explanation:
Draw a free body diagram (see attached). There are two tension forces acting upward at the edge of the cylinder, and weight at the center acting downwards.
The center rotates about the point where the cords touch the edge. Sum the torques about that point:
∑τ = Iα
mgr = (1/2 mr² + mr²) α
mgr = 3/2 mr² α
g = 3/2 r α
α = 2g / (3r)
(Notice that you have to use parallel axis theorem to find the moment of inertia of the cylinder about the point on its edge rather than its center.)
Now, sum of the forces in the y direction:
∑F = ma
2T − mg = m (-a)
2T − mg = -ma
Since a = αr:
2T − mg = -mαr
Substituting expression for α:
2T − mg = -m (2g / (3r)) r
2T − mg = -2/3 mg
2T = 1/3 mg
T = 1/6 mg
The tension in each cord is mg/6.
