The correct answer to the problemis velocity. I did the test.
This question can be solved by using Pythagora's Theorem.
The resultant magnitude of the movement is "42.5 units".
The x and y components of the movement are given. We can use Pythagora's Theorem to find the resultant of these movements. Hence, applying the Pythagora's Theorem<em>:</em>
where,
d = resultant movement = ?
= movement in x direction = 32 units
= movement in y direction = 28 units
Therefore,
<u>d = 42.5 units</u>

The attached picture shows Pythagora's Theorem<em>.</em>
Heat is added to the system.
The relation between thermal energy and temperature change in mass is given by the following expression
q = m•C•ΔT
where q is the quantity of heat transferred
m is the mass
C is the heat capacity of the material
ΔT is the temperature change
The rate at which the person is now losing thermal energy is 99 J/s.
<h3>
Thickness of the person's skin</h3>
The thickness of the person's skin is calculated as follows;
Q = k(ΔT)h
where;
- k is thermal conductivity
- h is thickness of the person's skin
- ΔT difference in temperature across the skin = 30 °C = 303 K
h = Q/k(ΔT)
h = (120) / (0.22 x 303)
h = 1.8 m
<h3>Rate at which the person is now losing thermal energy</h3>
Q = k(ΔT)h
where;
- ΔT is new temperature difference across the skin = 33 °C = 306 K
Q = (0.18)(306)(1.8)
Q = 99 J/s
Thus, the rate at which the person is now losing thermal energy is 99 J/s.

Answer:
1. Over time people became divided on issues and political parties developed in the United States. There have generally been two main political parties, but their ideals, platforms, and names have changed through time.
2. Disclosure of campaign spending makes the government and public aware of where all money is going and makes it harder for corrupt spending to occur.
