Average speed is the answer
KE= 0.5mv^2
165J= 0.5×(825kg+1kg)×v^2
165J = 413kg×v^2
v^2=165J÷413kg
v^2=0.39952 m^2/s^2 (5s.f.)
v= √0.39952= 0.632 m/s (3.s.f.)
If a ship will be sailing through warm and cold water, people think about making it less dense than the warmest water as they load the ship with cargo. I think you forgot to give the options along with the question. I hope that this is the answer that has actually come to your desired help.
The number of protons for an atom with 20 neutrons and 20 electrons will be 20.
<h3>
What is an atom ?</h3>
An atom is the smallest particle of an element. It consist of proton, neutron and electron.
To determine the number of protons and also identify the correct symbol for an atom with 20 neutrons and 20 electrons, we must first acknowledge the following facts
- Atom in a neutral state, the number of protons must be equal to number of electrons.
- Atom in a nuclear stable state, number of protons must be equal to the number of neutrons
Therefore, the number of protons for an atom with 20 neutrons and 20 electrons will be 20.
The symbol for this atom is Ca which is Calcium.

Answer: The geological area is where rock is recycled by one tectonic plate sliding underneath another tectonic plate is C. Subduction zone.
Explanation:
A Rift Valley is a large elongated depression with steep walls formed by the downward displacement of a block of the Earth’s surface between nearly parallel faults or fault systems.
A strike-slip fault is a fault in which rock strata are displaced mainly in a horizantal direction, parallel to the line of the fault.
A divergent boundary is a linear feature in that exists between two tectonic plates that are moving swat from each other.
A subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs add known as subduction zones.
so your answer is C.
