Answer: 5,728.5 years

Explanation:

By measuring the current ratio of daughter to parent, that is (Dt/Pt) one can deduce the age of any sample. The assumption is that there is no daughter atom present at time,t=0 and that the daughter atoms are due to the parent decay(where none has been lost).

Lamda= ln 2÷ half life,t(1/2)

Lamda= ln2= 0.693/5730 years

Lamda=1.21 × 10^-4

Using the formula below;

Age,t= 1/lamda× (ln {1+ Dt/Pt})------------------------------------------------------------------------------------(1)

Slotting our values into equation (1) above.

Age,t= 1/lamda(ln[1+1/1])

Age,t= 1/1.2×10^-4(ln 1+1)

Age,t= 1/1.21×10^-4(ln 2)

Age,t= ln 2/ 1.21×10^-4

Age, t= 5,728.5 years.

What is the difference between condensation and conduction
aniked [119]

Answer:

Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle.

A 10 m long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 30 m/s when a 68
timama [110]

Answer:

 v = 30.39 m/s

Explanation:

given,

mass of glider,M = 680 Kg

mass of the skydiver, m = 68 Kg

horizontal velocity,V = 30 m/s

when skydiver releases, velocity,v = 30 m/s

velocity if the glider,v' =  ?

use the conservation of momentum

M V = m' v' +  m v

m' = 680-68 = 612 Kg

680 x 30 = 612 x v + 60 x 30

612 v = 18600

 v = 30.39 m/s

since the skydiver's speed will be the same as before release

The glider should continue to travel at 30.39 m/s since there are no external forces acting on it

Explain how magnets have an attractive force and repulsive force
shusha [124]
The force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
