2.78 X 10^5 is the best answer to be responded to

AnnZ [28]3 years ago
3 0

278000 written in scientific notation would be 2.78×10⁵.

You can convert the number into scientific notation by doing the following:

1. Turn 278000 into 2.78000.

2. Move the decimal point to the end of the number, so that it becomes 278000 again.

3. Count the number of places that the decimal point was moved.

Since the decimal point was moved 5 places to the right, the exponent on the 10 will be positive five. Therefore, 278000 becomes 2.78×10⁵.

Describe how thermal energy is transferred​
ikadub [295]

Answer:

Thermal energy typically flows from a warmer material to a cooler material. Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation.

What current flows through a 2.56-cm-diameter rod of pure silicon that is 20.0 cm long, when 1.00 ✕ 103 V is applied to it? (Suc
vfiekz [6]

Answer:

Current, I = 0.0011 A

Explanation:

It is given that,

Diameter of rod, d = 2.56 cm

Radius of rod, r = 1.28 cm = 0.0128 m

The resistivity of the pure silicon, \rho=2300\ \Omega-m

Length of rod, l = 20 cm = 0.2 m

Voltage, V=1\times 10^3\ V

The resistivity of the rod is given by :

R=\rho\dfrac{L}{A}

R=2300\ \Omega-m\dfrac{0.2\ m}{\pi (0.0128\ m)^2}

R = 893692.30 ohms

Current flowing in the rod is calculated using Ohm's law as :

V = I R

I=\dfrac{V}{R}

I=\dfrac{10^3\ V}{893692.30\ \Omega}

I = 0.0011 A

So, the current flowing in the rod is 0.0011 A. Hence, this is the required solution.
