Which types of forces exist between the two protons in a helium nucleus?

Physics
1 answer:
777dan777 [17]3 years ago
5 0

Answer:

Option (2) is correct.

Explanation:

When two charges have equal charges they repel each other. On the other hand, if they have unequal charges they attract each other.

The force between the two protons in a helium nucleus is electrostatic charges and the force is repulsive in nature.

Also, there exists a strong nuclear force between charges.

So, a repulsive electrostatic force and an attractive strong nuclear force is the correct answer.

What is Digital data?

Digital data is information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits, in information theory and information systems. s. Binary data is the most common type of digital data in modern information systems. It is represented by a string of binary digits (bits), each of which can have one of two values, 0 or 1.

In contrast to digital data, analog data is represented by a value from a continuous range of real numbers.

What are two different ways to understand time? Explain and give examples.
Maru [420]
There are two different ways to understand time and these are:
A. What time is it?
B. How much time?
The examples of these two different ways are:
A. What time is it? The best example that would help us understand and know what time are the clock and the calendar. This gives us the exact hour, minutes and seconds. The calendar tells us the exact day, month and year.
B. How much time? This makes us understand how much time did it take from the starting time. An example for this would be a stopwatch.

The latent heat of vaporization of H₂O at body temperature (37°C) is 2.42 x 10⁶ J/kg. To cool the body of a 60.4-kg jogger [aver
Darya [45]

Answer:

<h2>0.094 kg</h2>

Explanation:

        Latent heat of vaporization of H_{2}O at 37°C is 2.42\times10^{6}\text{ }\frac{J}{kg}.

        When the sweat on our body evaporates, it absorbs energy from our body to overcome it's Latent heat of vaporisation. Thus our body cools down when sweat evaporates.

       So, Energy absorbed by sweat to evaporate = Energy lost by body

Specific heat capacity of human body = 3500\text{ }\frac{J}{kg\text{ }C^{o}}. Jogger weights 60.4 kg. Body temperature decreases by 1.08\text{ }C^{o}

       Energy absorbed from body = mS\Delta T=3500\times60.4\times 1.08 =228312\text{ }J

       228312\text{ }J=\text{Energy absorbed by sweat}=mC=m\times2.42\times10^{6}\\m=0.094\text{ }kg

∴ 0.094 kg of sweat has evaporated from the body.
