Explanation:
The given data is as follows.
mass = 10 kg, length = 4.5 m
speed (v) = 6 m/s
Now, formula to calculate tension is as follows.
T =
Putting the given values into the above formula as follows.
T = (here r = l)
=
= (98 + 80) N
= 178 N
Thus, we can conclude that tension in the rope at that point is 178 N.
Answer:
The combined momentum will be 2 units.
Explanation:
Here a piece of putty moving with 2 units of momentum strikes and sticks to a heavy bowling ball that is initially at rest. After the putty sticks to the ball, both are set in motion with a combined momentum. It is a case of inelastic collision in which the momentum of the system remains conserved.
The law of conservation of momentum will be followed here. So, the combined momentum after collision will be same as the initial momentum. Hence, the correct option is (b) "2 units".
Explanation:
- In chemical reactions, chemical changes occur.
- Atoms are simply rearranged and new bonds are formed.
- Chemical reactions are driven by a need for atoms to attain stability in their structure.
- In all chemical reactions, a reactant or reactants gives new product i.e new substances are formed.
- Most these reactions are not easily reversible.
- They are usually accompanied by the release of energy.

Answer:
Trenches are the deepest part of the oceans, narrow and long depressions on the sea floor. One good example is the Mariana Trench, the deepest part of the ocean
Explanation:
There is zero net force required to keep an object moving, even in the same direction. This is because the inertia only depends on the mass of the object moving, not the speed. Therefore, the answer would be none.
