the higher concentration of molecules, the faster a reaction can occur
International Disaster Management or FEMA
Explanation:
In order to calculate the work from r = a to r = b we only need to convert 1000 km into 1,000,000 m.
Since, the given data is as follows.
G =
= 1000 kg
a =
b =
=
Now, we will calculate the work as follows.
W =
=
=
thus, we can conclude that work required to launch the satellite is .
Answer:
Explanation:
Initial magnetic flux = magnetic field x area
= 4.4 x 5 x 10⁻³
= 22 x 10⁻³ weber
Final magnetic flux
= 1.32 x 5 x 10⁻³
= 6.6x 10⁻³ weber
change in magnetic flux = 15.4 x 10⁻³
emf induced = change in flux / time
= 15.4 x 10⁻³ / 22 x 10⁻³
= .7 V
current in bracelet = emf / resistance
= .7 / .02
= 35 A
b )
power = volt induced x current
= .7 x 35
= 24.5 W .
