<em>A burning candle</em> is a great example.

First the wax melts (physical change).

Then when the melted wax is hot enough, it combines with oxygen in the air, forms carbon monoxide and carbon dioxide, and drifts away as hot gases (chemical change).

An electron is released from rest in a weak electric field given by E,--2.50 x 10.10 N/C j. After the electron has traveled a ve

Olegator [25]

Answer:

$v = 1.26 \times 10^8 m/s$

Explanation:

Force on an electron while it moves through constant electric field is given as

$F = eE$

$e = 1.6 \times 10^{-19} C$

$E = 2.50 \times 10^{10} N/C$

$F = (2.50 \times 10^{10})(1.6 \times 10^{-19})$

$F = 4 \times 10^{-9} N$

now by work energy theorem we can say

Work done by electric field = kinetic energy of the electron

$F . d = \frac{1}{2}mv^2$

$(4 \times 10^{-9})(1.8 \times 10^{-6}) = \frac{1}{2}(9.11 \times 10^{-31})v^2$

$v = 1.26 \times 10^8 m/s$

The triceps muscle in the back of the upper arm is primarily used to extend the forearm. Suppose this muscle in a professional b

bagirrra123 [75]

To solve this problem it is necessary to address the concepts related to Torque as a function of the force and distance where it is applied and the moment of inertia from which the torque, moment of inertia and angular acceleration are related.

By definition the torque is defined as

$\tau = F*r$

Where,

$\tau = Torque$

F = Force

r = Radius

For our values we have:

$\tau = F*r$

$\tau = (1.75*10^3)(2.8*10^{-2})$

$\tau = 49Nm$

Consequently the calculation of the moment of inertia would then be given by the relationship

$\tau = I\alpha$

$I=\frac{\tau}{\alpha}$

Replacing with our values

$I = \frac{49}{150}$

$I = 0.322Kg.m^2$

The moment of inertia of the boxer's forearm $0.322Kg.m^2$

A student grabs a piece of paper and tears it from the middle. Which statement best explains the forces involved?

PolarNik [594]

Answer:

b. The normal force between the molecules of the paper is overcome by the contact force of the hands.

Explanation:

The paper molecules are held together by a weak bond. When the student holds the paper on both sides with the center of the paper in between, the student applies two equal forces in the opposite direction of the paper making the paper molecules weaken and separate.
