Answer: This phenomenon happens due to upthrust exerted by water.
Explanation:
We know that,
Liquid Pressure is directly proportional to the height of the vertical column in the liquid.(P∝h)
When a bucket filled water is sunk into the water container, there occur difference in the pressure in top and bottom of the water container. Due to this, water exerts an upward force on the bucket filled with water. This is called Uprthrust.
Upthrust on the bucket makes the bucket filled with water lose some of it's weight and causes apparent loss in weight.
Hence, the bucket filled with water seems light while it sinks into water.
Answer:
μ = tanθ = tan30 = 0.58
Explanation:
μ = force parallel/force perpendicular = mgsinθ/mgcosθ = tanθ
Answer:
the tension generated on the vine is equal to 784.8 N
Explanation:
As Tarzan is testing the strength of vine
to test the vine Tarzan hangs on it.
given,
mass of Tarzan = 80 kg
acceleration due to gravity = 9.81 m/s²
tension on the wire will be
T = m × g
T = 80 kg × 9.81 m/s²
T = 784.8 kg.m/s²
T = 784.8 N
hence, the tension generated on the vine is equal to 784.8 N
Answer:
-0.056 is the deceleration
Stars are a source of light and heat. They recycle all the matter, gas, and dust and process them into new material. They were created as a major driving force of evolution of the universe.
