The momentum of an object is determined to be 7.2 X 10-3 kg m/s. Express this quantity as provider or use any equivalent unit.
olasank [31]

There could be more than just one answer, since kilograms can be converted to grams, to miligrams, etc.

7.2\frac{g.m}{s}

or

7200\frac{mg.m}{s}

Why?

Let's remember some conversion factors to work with kilograms (kg)

1kg=1000g=1x10^{3}g \\1kg=1,000,000mg=1x10^{6}mg \\1g=1000mg=1x10^{3}mg

So, we are given the momentum:

momentum=7.2x10^{-3} \frac{kg.m}{s}

We can rewrite the units of the momentum (equivalent) as follow:

momentum=7.2x10^{-3}kg \frac{m}{s}=7.2x10^{3} x10^{-3}g\frac{m}{s}=7.2\frac{g.m}{s}

and

momentum=7.2x10^{-3}kg \frac{m}{s}=7.2x10^{3} x10^{6}mg\frac{m}{s}=7.2x10^{3}\frac{mg.m}{s}

Note: There could be more equivalent units for the momentum, in example, we could work with equivalent units for meters (distance) and seconds (time).

Have a nice day!

A beam of protons is moving in the x direction with a speed of 10.6 km/s through a region in which the electric field is perpend
nataly862011 [7]

Answer:

E= 8501.2

Explanation:

Given Data;

Speed = 10.6 km/s = 10.6*10^3 m/s

Magnitude = 0.802 T

The magnitude of the electric field is calculated using the formula;

q E = q v B

E = v B

   = 10.6 *10^3 * 0.802

   = 8501.2

The direction of the electric field will point along the negative z-axis

Calculate the pressure of water at depth 10metre given that:Density of water=1000 kg/m^3
Sergeeva-Olga [200]

Answer:

We begin by solving the equation P = hρg for depth h: h=Pρg h = P ρ g . Then we take P to be 1.00 atm and ρ to be the density of the water that creates the pressure.
