Conduction involves the transfer of electric charge or (thermal energy)

Tema [17]4 years ago

Answer: The correct answer is "thermal energy".

Explanation:

Conduction: Heat flows from hotter body to colder body provided they are placed in direct contact with each other until the temperatures on both bodies become equal. In conduction, there is not actual movement of matter.

Thermal energy: It is the energy that comes from the heat.

or

Conduction is the process in which there is a transfer of the electrons between the charged object to the another object provided the objects are in direct contact with each other. The electrons are transferred from the object having more negative charge to the object that has more positive charge. There is a transfer of the electrons until the charges on both the objects become equal.

Therefore, the conduction involves the transfer of the electric charge or thermal energy.

If a 2kg ball has and initial velocity of

lakkis [162]

Answer:

$\boxed {\boxed {\sf 12 \ Newtons }}$

Explanation:

Force is equal to the product of mass and acceleration.

$F=m*a$

We know the mass, but not the acceleration. Therefore, we must calculate it before we can calculate force.

1. Calculate Acceleration

Acceleration is the change in velocity over the change in time.

$a=\frac{V_f-V_i}{t}$

The final velocity is 10 meters per second and the initial velocity is 4 meters per second. The time is 1 second.

$V_f=10 \ m/s \\V_i= 4 \ m/s \\t= 1 \ s$

Substitute the values into the formula.

$a=\frac{10 \ m/s-4 \ m/s }{1 \ s}$

Solve the numerator.

$a=\frac{6 \ m/s}{1 \ s }$

Divide.

$a= 6 \ m/s/s=6 \ m/s^2$

2. Calculate Force

Now we know the acceleration and the mass.

$m= 2 \ kg \\a= 6 \ m/s^2$

Substitute the values into the fore formula.

$F= 2 \ kg * 6 \ m/s^2$

Multiply.

$F= 12 \ kg*m/s^2$

1 kilogram meter per square second is equal to 1 Newton.
Our answer of 12 kg*m/s² is equal to 12 Newtons

$F= 12 \ N$

The force applies to the ball was <u>12 Newtons.</u>

Future space stations will create an artificial gravity by rotating. Consider a cylindrical space station 780 m diameter rotatin

ser-zykov [4K]

Answer:1.513 rps

Explanation:

Given

Diameter of cylindrical space $d=780\ m$

When the station rotates it creates centripetal acceleration which is given by

$a_c=\omega ^2r$

Now it must create the effect of gravity so

$g=\omega ^2r$

$\omega =\sqrt{\frac{g}{r}}$

$\omega =0.158\ rad/s$

and $\omega =\frac{2\pi N}{60}$

Thus $N=\frac{4.755}{3.142}$

$N=1.513\ rps$
