The person will feel cold.

Exothermic processes involve the loss of heat from the system, whereas endothermic processes bring heat into the system. Since heat is being lost from the system and heating up the test tube, reaction A is exothermic. The primary distinction between exothermic and endothermic reactions is that the former releases energy into the environment while the latter collects energy in the form of heat from its surroundings. Heat and light are significant indicators that a reaction has occurred when two chemicals are together. The reaction is exothermic if heat is released. Exothermic refers to a reaction in which molecules have transitioned from a higher to a lower energy state.

Keeping the applied voltage constant at approximately 0.70 volts, measure the electric field strength at different points betwee
Vitek1552 [10]

Answer: I observed that the electric field strength is the same at all points between the plates. The value of the field is 70 volts per meter. This is exactly 100 times the applied voltage. The electric field lines point from the positive plate to the negative plate, as the downward arrow on the detector shows.

An insect crawls 4 m east along a hiking path in
alexandr1967 [171]

The insect's velocity is 0.2 meter/second along east.

<h3>What is velocity?</h3>

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Given parameters:

An insect crawls 4 m east along a hiking path.

Time taken by it: t = 20 seconds.

We have to fine: the insect's velocity, v =?

So, the magnitude of velocity: v= 4/20 meter/second = 0.2 meter/second.

And the direction velocity is along east.

Hence,  the insect's velocity is 0.2 meter/second along east.

If an object force of 50 N is used to move an object a distance of 20 m, what distance must the object be moved if the input for
steposvetlana [31]

Answer:

\ d_{out} = 100 \ m.

Explanation:

Given data:

F_{in} = 50 \ \rm N

F_{out} = 10 \ \rm N

d_{in} = 20 \ m

Let the distance traveled by the object in the second case be d_{out}.

In the given problem, work done by the forces are same in both the cases.

Thus,

W_{in} = W_{out}

F_{in}.d_{in} = F_{out}.d_{out}

\Rightarrow \ d_{out} = \frac{F_{in}.d_{in}}{F_{out}}

\ d_{out} = \frac{50 \times 20}{10}

\ d_{out} = 100 \ m.
