a)The velocity of the knife relative to the ship when it hits the deck of the ship will be 14.00 m/sec.
b)The velocity of the knife relative to a stationary observer on shore is 14.10 m/sec
c)The position at which the knife hits the deck is 82.8°.
<h3 /><h3>What is velocity?</h3>
The change of displacement with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.
The given data in the problem is;
The velocity of the knife relative to the ship when it hits the deck of the ship is;
v=√2gh
v=√2×9.81 ×10.0 m
v=14.00 m/sec
b)
The velocity of the knife relative to a stationary observer on shore is found as;
v₁₂ = √[(14.00)²+(1.74)²]
v₁₂=14.10 m/sec
c)
The position at which the knife hits the deck is;
Hence, the velocity of the knife relative to the ship, the velocity of the knife relative to a stationary observer on shore, and the position at which the knife hits the deck will be 14.00 m/sec,14.10 m/sec, and 82.8° respectively.

Answer:
option (d)
Explanation:
Energy is defined as the capacity to do work.
Energy can neither be created and nor be destroyed, it can transform from one form to another.
The SI unit of energy is Joule and teh commercial unit of energy is kilowatt hour.
There are several forms of energy.
1. kinetic energy
2. potential energy
3. mechanical energy
4. Solar energy
5. Sound energy
Answer:
Shear stress on upper plate = 837.4N/m2
Shear stress when the linear velocity profile were assumed = 418.7N/m2
Explanation:
The detailed and step by step calculation and appropriate differentiation to get the shear stress is as shown in the attachment.
if it is heat flow through a metal, it would be necessary to have a conductor so that the electrons can flow through it (delocalised electrons).
In terms of radiation, it would require a good absorber of heat (e.g. a black surface) so that the thermal energy flows through on the surface area.
The correct answer is<span> gases, energy, temperature, phases
Gravity and nuclear forces are not encompassed in the kinetic molecular theory as it deals with movement and behavior of gas molecules. It does not include their conversion to other types of energy or anything similar. </span>
