There is a potential difference of 1.1 V between the ends of a 10 cm long graphite rod that has a cross-sectional area of 0.90 m

Serga [27]

Explanation:

It is given that,

Potential difference between the ends of a rod, V = 1.1 V

Length of the rod, l = 10 cm = 0.1 m

Area of cross section of the rod, $A=0.9\ mm^2=9\times 10^{-7}\ m^2$

The resistivity of graphite, $\rho=7.5\times 10^{-6}\ \Omega-m$

(a) Let R is the resistance of the rod. It is given by :

$R=\rho \dfrac{l}{A}$

$R=7.5\times 10^{-6}\times \dfrac{0.1}{9\times 10^{-7}}$

$R=0.833\ \Omega$

So, the resistance of the rod is 0.833 ohms.

(b) Let I is the current flowing in the wire. It can be calculated using the Ohm's law as :

$I=\dfrac{V}{R}$

$I=\dfrac{1.1\ V}{0.833\ \Omega}$

I = 1.32 A

(c) Let E is the electric field inside the rod. The electric field in terms of potential difference is given by :

$E=\dfrac{V}{l}$

$E=\dfrac{1.1\ V}{0.1\ m}$

E = 11 V/m

Hence, this is the required solution.

Answer:

b. Medicine balls

Explanation:

A medicine ball (also called an exercise ball, or a health ball) is a weighted ball about the shoulder diameter (approx. 13.7 inches), often used for recovery and strength training.... In 1705 similar large balls had been used in Persia.So you can use your medicine ball as a projectile to boost the strength of your throws.

Calcular la aceleración que produce una fuerza de 40 N sobre un cuerpo con 88 Kg de masa. Expresar el resultado en m⁄s^2 *

tigry1 [53]

Answer:

a = 0.45 m/s²

Explanation:

The given question is ''Calculate the acceleration that produces a force of 40 N on a body with 88 kg of mass".

Given that,

Force, F = 40 N

Mass of the body, m = 88 kg

The net force acting on the body is given by :

F = ma

Where

a is the acceleration of the body

$a=\dfrac{F}{m}\\\\a=\dfrac{40\ N}{88\ kg}\\\\a=0.45\ m/s^2$

So, the required acceleration is 0.45 m/s².

why do a circulatory system is important in meeting the needs of all cells throughout an animals body

valentinak56 [21]

The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function. The functions of the circulatory system by which the cells are supported include: 1. Respiration- oxygen is delivered to the cells and carbon dioxide is removed from them. 2. Nutrition- nutrients for energy are supplied to every cell in the body. 3. Waste removal- metabolic waste products are taken away before they accumulate and become harmful to the cells. 4. Cellular communication- hormones are transported to the cells and organs that need them for proper functioning. 5.Thermoregulation- As blood circulates, it keeps body temperature balanced and thus cells are able to carry out processes well.
