Answer:
Explanation:
Let the height of the tree is y and the distance of tree from point B is x.
According to the diagram
x = 0.55 y ..... (1)
(50 + 0.55y) 1.17 = y ..... from equation (1)
58.5 + 0.644 y = y
0.356 y = 58.5
y = 164.3 ft
Answer:
Sugar
Explanation:
Nisha's list: Amol's list
Jute Vinegar
Wood Lemon juice
Rubber Cooking soda
Nisha's list is made up of things that can be derived from plants. From the list given, oil, sugar and cotton can also be obtained from plants.
Most plant materials are organic matter.
Amol's list is made up of things that can dissolve in water. Sugar and table salt can also be dissolved in water.
Water is able to dissolve these materials because they are polar compounds. One rule of solubility is that like dissolves like.
New list:
Nisha's list: Amol's list
Jute Vinegar
Wood Lemon juice
Rubber Cooking soda
Sugar Sugar
Only sugar from the list can be added to both lists. It can be obtained from plant and can also dissolve in water.
Answer:
why should we do , do by your own , no sense
Explanation:
Answer:
Final velocity of the block = 2.40 m/s east.
Explanation:
Here momentum is conserved.
Initial momentum = Final momentum
Mass of bullet = 0.0140 kg
Consider east as positive.
Initial velocity of bullet = 205 m/s
Mass of Block = 1.8 kg
Initial velocity of block = 0 m/s
Initial momentum = 0.014 x 205 + 1.8 x 0 = 2.87 kg m/s
Final velocity of bullet = -103 m/s
We need to find final velocity of the block( u )
Final momentum = 0.014 x -103+ 1.8 x u = -1.442 + 1.8 u
We have
2.87 = -1.442 + 1.8 u
u = 2.40 m/s
Final velocity of the block = 2.40 m/s east.
Answer:
The ball slows down in the air due to an unbalanced force
Explanation:
When player kicks the ball, there are mainly two foces acting on this object: the force made by the player and the opposite force of gravity (which acts with a direction always to the centre of the Earth)
The force applied by the player will be decreasing, while the force of gravity is always constant, this will make that both forces will unbalance, making the football´s speed slow down
