How is heat similar to and different from internal energy?

Physics

svlad2 [7]3 years ago
5 0

Answer:

Heat is similar to and different from internal energy

Explanation:

Similarity:

First thing to remember is that heat and internal energy are both different forms of energy. Secondly, heat is directly proportional to internal energy. When you provide heat to the system, its internal energy will increase. So, heat is the part of internal energy.

Difference:

Internal energy is the summation of kinetic and potential energy of a system, means it depends upon movement of particles as well as the particular position of the system while heat is the transfer of the energy due to difference of degree of hotness and coldness of body or a system.

Based on the information given, it can be posited that Kyle has a general anxiety disorder.

Generalized Anxiety Disorder is a disorder that is characterized by persistent and excessive worry about different things. People with the disorder may anticipate disaster and are concerned about money, health, family, or other issues.

Some of the effective ways of treatment are spending more time with family and friends, doing regular exercises , enough sleeping, etc.

A furlong is 220 yd. A fortnight is 2 weeks. Convert a speed of one furlong per fortnight to millimeters per second.
nlexa [21]

Answer:

0.1663\frac{mm}{s}

Explanation:

You need to convert furlongs to yards to mm:

\frac{1 furlong}{1 fortnight}*\frac{220 yd}{1 furlong}*\frac{0.9144m}{1yd}*\frac{1000mm}{1m} = \frac{201168 mm}{1 fortnight}

Now, we convert fortnight to seconds:

\frac{201168 mm}{1 fortnight}*\frac{1 fortnight}{2 weeks}*\frac{1 week}{7 days} *\frac{1 day}{24 h}*\frac{1 h}{3600s}  = 0.1663\frac{mm}{s}

A person in a kayak starts paddling, and it accelerates from 0 to 0.680 m/s in a distance of 0.428 m. If the combined mass of th
d1i1m1o1n [39]

Answer:

Net force, F = 44.66 N

Explanation:

It is given by,

Initial velocity of the person, u = 0

Final velocity of the person, v = 0.68 m/s

Distance, s = 0.428 m

Combined mass of the person and the kayak, m = 82.7 kg

We need to find the net force acting on the kayak i.e.

F = ma...........(1)

Firstly, we will calculate the value of "a" from third equation of motion as :

v^2-u^2=2as

a=\dfrac{v^2-u^2}{2s}

a=\dfrac{(0.68\ m/s)^2-0}{2\times 0.428\ m}

a=0.54\ m/s^2

Put the value of a in equation (1) as :

F=82.7\ kg\times 0.54\ m/s^2

F = 44.66 N

So, the net force acting on the kayak is 44.66 N. Hence, this is the required solution.

A 2 N and an 8 N force pull on an object to the right and a 4 N force pulls on the same object to the left. If the object has a
Elden [556K]

Answer:

a = 12 [m/s²]

Explanation:

To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

ΣF = m*a

where:

ΣF = sum of forces acting on a body [N] (units of Newtons)

m = mass = 0.5 [kg]

a = acceleration [m/s²]

Let's take the direction of positive forces to the right and negative forces directed to the left

2 + 8 - 4 = 0.5*a

6 = 0.5*a

a = 12 [m/s²]
