Answer:Orient your line of sight directly above the measurement markings.

Explanation: parallax error is a type of systematic error that occurs when an observer views a measurement marking at a wrong angle. This causes a noticeable disparity in results obtained. Therefore the best way to prevent this error is to view and record the data from the correct angle. This can be obtained by:

-Place the measurement device on its edge so it is level with the object being measured.

-Seek out the finest possible edge of the measurement device, or use a device with finer edges.

In conclusion, ask other observers to also take the reading and get an average of their results. It can help cancel out parallax error results.

Fine grains of beach sand are assumed to be spheres of radius 64.8 µm. These grains are made of silicon dioxide which has a dens
Nutka1998 [239]

Answer:

1) Mass of the grain is 2.9632\times 10^{-9} kg.

2) 0.08901 kg of sand would have surface area equal the surface area of the cube.

Explanation:

1) Radius of the grain,r = 64.8 µm =6.48\times 10^{-5}m

Volume of the sphere =\frac{4}{3}\pi r^3

Volume of the grain of a sand:

V=\frac{4}{3}\times \pi r^3=\frac{4}{3}\times 3.14\times (6.48\times 10^{-5} m)^3

V=1.1397\times 10^{-12} m^3

Density of a grain of sand = d=2600 kg/m^3

Mass of a grain of a sand = M

d=2600 kg/m^3=\frac{M}{1.1397\times 10^{-12} m^3}

M=2.9632\times 10^{-9} kg

Mass of the grain is 2.9632\times 10^{-9} kg.

2) Surface are of sphere: 4\pi r^2

Surface area of a grain:

A=4\times 3.14\times (6.48\times 10^{-5}m)^2

A=5.2766\times 10^{-8} m^2

Length of the cube = a = 0.514 m

Total surface area of cube ,A'= 6a^2

A'=6\times (0.514 m)^2=1.5851 m^2

let the number grains with area equal to total surface area of cube be x.

A'=A\times x

x=\frac{1.5851 m^2}{5.2766\times 10^{-8} m^2}=3.003\times 10^7

Volume of x number of grains :V'

V'=V\times x

V= 1.1397\times 10^{-12} m^3\times 3.003\times 10^7

V'=3.4236\times 10^{-5} m^3

Mass of 3.4236\times 10^{-5} m^3 of sandL:

=3.4236\times 10^{-5} m^3\times 2600 kg/m^3=0.08901 kg

0.08901 kg of sand would have surface area equal the surface area of the cube.

Calculate the force of gravity on the 1.2-kg mass if it were 1.9×107 m above earth's surface (that is, if it were four earth rad
Anettt [7]

Answer:

Force of gravity, F = 0.74 N

Mass of an object, m = 1.2 kg

Distance above earth's surface, d=1.9\times 10^7\ m

Mass of Earth, M=5.97\times 10^{24}\ kg

Radius of Earth, r=6.37\times 10^6\ m

We need to find the force of gravity above the surface of Earth. It is given by :

F=G\dfrac{mM}{R^2}

R = r + d

R = 25370000 m

F=6.67\times 10^{-11}\times \dfrac{5.97\times 10^{24}\ kg\times 1.2\ kg}{(25370000\ m)^2}

F = 0.74 N

So, the force of gravity on the object is 0.74 N. Hence, this is the required solution.

Why is a steam burn more damaging than a burn from boiling water at the same temperature?
maksim [4K]
The phase change (from gas to liquid) that the steam undergoes right when it touches your skin releases a lot of energy right onto your skin so it burns a ton. The boiling water would just burn you until it reaches the same temperature as your skin.
