Suppose you have 150. ml of a substance with density of 42.0 g/dm3. convert the volume from milliliters to liters to cubic decim

eters, then determine the mass of the sample in grams. also show the unit analysis by dragging components into the unit-factor slots below. the question marks (?) represent the answer to the previous step.

First let's make the conversions corresponding to the volume:
 milliliters to liters:
 150 (ml) * (1/1000) (L / mL) = 0.15 L
 Liters to cubic decimeters
 0.15L * (1/1) (dm ^ 3 / L) = 0.15 dm ^ 3
 Then, by definition, density is equal to mass between volumes:
 d = m / v
 Clearing the mass we have:
 m = d * v
 Substituting:
 m = (42.0 g / dm3) * (0.15 dm ^ 3)
 m = 6.3g
 answer:
 the mass of the sample in grams is
 m = 6.3g

In a particle accelerator a positron (C= +1.6 x 10-19) travels through a perpendicular magnet field with a magnitude of 3.1 x 10-2 T. At what speed must the positron travel in order for it to experience a force of 4.75 x 10-14 N? 28. An alpha particle (2 protons and 2 neutrons) experiences a downward force of 2.9 x 10-14 N while traveling in a magnetic field with a strength of 5.1 x 10-19 T pointing to the north. Find the speed of the particle and the direction it must be traveling in. 29.

A force of 30.0 N is applied to a 3.00 kg object for 3.00 seconds. Calculate the velocity experienced by the object.
olganol [36]

Answer:

Explanation:

F = ma and

a=\frac{v}{t}

We have F, we have m, but in order to solve for v, we need a.

30.0 = 3.00a so

a = 10.0 m/s/s. Plug that in for a in the second equation and solve for v:

10.0=\frac{v}{3.00} so

v = 10.0(3.00) so

v = 30.0 m/s
