A freighter carrying a cargo of uranium hexafluoride sank in the English Channel in late August 1984. The cargo of uranium hexaf

luoride weighed 2.25 x 108 kg and was contained in 30 drums, each having a volume of 1.62 x 106 L. What is the density (g/mL) of uranium hexafluoride?

Answer:

\rho = 4.63 g/mL

Explanation:

Volume of each drum in which the Uranium Hexafluoride is contained is given as

V = 1.62 \times 10^6 L

V = 1.62 \times 10^9 mL

now we know that mass of the uranium is given as

m = 2.25 \times 10^8 kg

now total volume of all 30 containers is given as

V = 30 (1.62 \times 10^9)

V = 4.86 \times 10^{10} mL

m = 2.25 \times 10^{11} g

so now the density is given as

\rho = \frac{m}{V}

\rho = \frac{2.25 \times 10^{11}}{4.86 \times 10^{10}}

\rho = 4.63 g/mL

A ball is thrown up with a speed of 15m/s. How high will it go before it begins to fall? ( g = 10m/s2 )
LekaFEV [45]

Answer:

Height is 11.25m

Explanation:

<u>Given the following data;</u>

Initial velocity, u = 0

Final velocity, v = 15m/s

Acceleration due to gravity, g = 10m/s²

To find the height, we would use the third equation of motion;

V^{2} = U^{2} + 2aS

Where;

  • V represents the final velocity measured in meter per seconds.
  • U represents the initial velocity measured in meter per seconds.
  • a represents acceleration measured in meters per seconds square.
  • S represents the displacement (height) measured in meters.

V^{2} = U^{2} + 2aS

<em>Making S the subject, we have;</em>

S = \frac {V^{2} - U^{2}}{2a}

But a = g = 10m/s²

<em>Substituting into the equation, we have;</em>

S = \frac {15^{2} - 0^{2}}{2*10}

S = \frac {225 - 0}{20}

S = \frac {225}{20}

S = 11.25m

<em>Therefore, the ball will reach a height of 11.25m before it begins to fall. </em>

What kind of charge does an object have if it has extra positive charges
Sever21 [200]
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

The single-pole, single-throw switch is normally wired ? between the source and the load to turn devices on and off.
zzz [600]

In series.

Single-pole and single-throw switch:

A switch with only one input and one output is referred to as a Single Pole Single Throw (SPST) switch. This indicates that it has a single output terminal and a single input terminal.

A single pole, one throw switch functions as an on/off switch in circuits. The circuit is turned on when the switch is closed. The circuit is shut off when the switch is open.

Thus, SPST switches are relatively basic in design.

Circuit for a single-pole, single-throw (SPST) switch

Types:

According to the application, it can be divided into three categories, including:

  • Simple SPST
  • (ON)-OFF, Push-to-close, SPST Momentary
  • ON-(OFF), Push-to-Open, SPST Momentary
  • Inches Switch SPST
