Why is a force required to keep a body moving with a uniform speed in a circular motion?

andrew-mc [135]

Because if there's no force on the object, then it just moves in a straight line.

The internal energy of a system increases by 36 joules. The system does work using 17 joules. What amount of heat was added to t

Ray Of Light [21]

General internal energy expression:

Uf = (Ui-W) + Q

Where Uf = Final internal energy, Ui = Initial internal energy, W = Work done, Q = Heat added

But,
Uf -Ui = ΔU = 36 J, W = 17 J. Then,
ΔU = -W +Q => Q = ΔU+W = 36+17 = 53 J

Therefore, heat added to the system is 53 Joules

What is the energy of the electron in a helium ion with a charge of +1 in an orbit with a value of n=4?

goldenfox [79]

Answer:

The energy of the electron in a helium ion is $-5.44\times10^{-19}\ J$

Explanation:

Given that,

Charge = +1

Value of n = 4

Suppose $k=2.179\times10^{-18}\ J$

We need to calculate the energy of the electron in a helium ion

Using formula of energy

$E_{n}=-k\dfrac{z^2}{n^2}$

Put the value into the formula

$E_{n}=-2.179\times10^{-18}\times\dfrac{2^2}{4^2}$

$E_{n}=-5.44\times10^{-19}\ J$

Hence, The energy of the electron in a helium ion is $-5.44\times10^{-19}\ J$
