What is acceleration due to gravity

Volgvan

The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation and the centrifugal force. In SI units this acceleration is measured in metres per second squared or equivalently in newtons per kilogram.

A block of wood measures 12cm x 5cm x 10cm. Calculate the volume in (i) cm3 (ii) m3

Anit [1.1K]

Given:-

A block of wood measures 12cm x 5cm x 10cm.

To be calculated:- 

Calculate the volume in (i) cm3 (ii) m3

Solution:-

Case 1 :

Volume of wood = 12cm x 5cm x 10cm

= 600 cm³

Case 2 :

12 cm = 12/100 = 0.12 m

5 cm = 5/100 = 0.05 m

10 cm = 10/100 = 0.01 m

Volume of wood = 0.12 × 0.05 × 0.01

= 0.00006 m³

A car is moving with a constant speed v around a level curve. The coefficient of friction between the tires and the road is 0.40

Salsk061 [2.6K]

Answer:

Minimum radius of the curve to stay on the road will be equal to $0.255v^2m$

Explanation:

We have given coefficient of kinetic friction $\mu =0.40$

Acceleration due to gravity $g=9.8m/sec^2$

We have to find minimum radius of the curve so that car will stay on the road

For the car to stay on the road centripetal force must be equal to frictional force

So $\frac{mv^2}{r}=\mu mg$

So minimum radius of the

$r=\frac{v^2}{\mu g}=\frac{v^2}{0.4\times 9.8}=0.255v^2m$

So minimum radius of the curve to stay on the road will be equal to $0.255v^2m$

What is the speed of all forms of electromagnetic radiation in a vacuum

marysya [2.9K]

Answer:

$3.0 \cdot 10^8 m/s$ (speed of light)

Explanation:

Electromagnetic waves are oscillations of the electric and the magnetic field that occur in a plane perpendicular to the direction of travelling of the wave.

All electromagnetic waves travel in a vacuum at the same speed, whose value is:

$c=3.0\cdot 10^8 m/s$

And this value is called speed of light.

Electromagnetic waves are classified into 7 different types, depending on their wavelength/frequency. From highest to lowest frequency, we have:

Gamma rays

X-rays

Ultraviolet radiation

Visible light

Infrared radiation

Microwaves

Radio waves
