The person's velocity relative to the shore is determined as 6.5 m/s.
<h3>
Velocity of the person</h3>
The velocity of the person is calculated as follows;
V(p/f) = V(p) - V(f)
where;
- V(p/f) is the velocity of the person relative to the ferry
- V(p) is the velocity of the person
- V(f) is velocity of the ferry
1.5 = V(p) - 5
V(p) = 6.5 m/s
Thus, the person's velocity relative to the shore is determined as 6.5 m/s.

Answer:
Water has high specific heat capacity so without a high increase in temperature , water can absorb a large amount of heat.
Explanation:
Water is a very good substance for use in cooling system of automobiles because water has a ridiculously high heat capacity specially its volumetric heat capacity.
water takes a tremendous energy to change the temperature of water and and it gives enormous cooling capacity compared to metals like rapidly absorbing heat energy from the engine.
To cool down the car engine water is used. Water has high specific heat capacity so without a high increase in temperature , water can absorb a large amount of heat.
Water is efficient heat transfer fluid .
Water offers the thermal conductivity advantages of a liquid with high specific heat capacity and evaporative cooling .
Answer:
A. Pu -239
Explanation:
An isotope is an element with the same atomic number but different mass number. most isotope are unstable, having short half life.
Curium-242 is an isotope produced when Plutonium 239 is bombarded by an alpha particle. This reaction between Plutonium 239 and alpha particle gives curium-242, neutron and a high amount of energy as the products.
Curium oxidizes easily, and it is a dangerous metal which can cause cancer initiation when absorbed by biological materials e.g bones or tissue.
