Answer:
a = 2.72 ms⁻²
32.83 s
Explanation:
By using the kinematic equations you get,
v² = u² +2as and v = u + at where all terms in usual meaning
Using 1st equation,
89.3² = 0² + 2a×1465 ⇒ a = 2.72 ms⁻²
By 2nd equation,
89.3 = 0 + 2.72×t ⇒ t = 32.83 s
Explanation:
The water molecules begins to leave their fixed position and begins to move as the temperature increases.
When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.
- The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
- In the ice, the molecules are locked and fixed in the lattice
- As the temperature increases, the average kinetic energy of the particles rises.
- This makes the structure of the ice to collapse and forms liquids.
- By the virtue of this, they flow and move over one another
- With increasing temperature, the bonds are broken and vapor forms
Answer:
The work done by the applied force is 259.22 J.
Explanation:
The work done by the applied force is given by:

Where:
F: is the applied horizontal force = 108.915 N
d: is the distance = 2.38 m
Hence, the work is:

Therefore, the work done by the applied force is 259.22 J.
