A velocity selector in a mass spectrometer uses a 0.100-T magnetic field. (a) What electric field strength is needed to select a
Wewaii [24]

Answer:

The electric field strength needed is 4 x 10⁵ N/C

Explanation:

Given;

magnitude of magnetic field, B = 0.1 T

velocity of the charge, v = 4 x 10⁶ m/s

The velocity of the charge when there is a balance in the magnetic and electric force is given by;

v = \frac{E}{B}

where;

v is the velocity of the charge

E is the electric field strength

B is the magnetic field strength

The electric field strength needed is calculated as;

E = vB

E = 4 x 10⁶ x 0.1

E = 4 x 10⁵ N/C

Therefore, the electric field strength needed is 4 x 10⁵ N/C

What is the density of ocean water if 308.19g fills a 300mL container?
mojhsa [17]

Answer:

Density = 1027.3 [kg/m3]

Explanation:

To solve this problem we must use the concept of density which is defined as the relationship between mass and volume, which can be determined by the following equation.

density = m/v

m = mass = 308.19 [gramm] = 0.30819 [kg]

v = volume = 300 [mL] = 0.3 [Lt] = 0.0003 [m3]

density = (0.30819/0.0003)

density = 1027.3 [kg/m3]
