What is the acceleration, in meters per second squared, of a 2,000,000-kilogram NASA rocket with an applied force of 20,000,000

Answer:

10m/s^2

Explanation:

Force = mass x acceleration

Acceleration = force/ mass

= 20000000/2000000

=10m/s^2

In an NMR experiment, the RF source oscillates at 34 MHz and magnetic resonance of the hydrogen atoms in the sample being in- ve

choli [55]

Answer:

$B_{int}=-0.015T$

Explanation:

From the question we are told that:

RF source oscillation speed $\sigma= 34 MHz$

The external field $Bext =0.78 T$ .

Pro- ton magnetic moment component $\mu=1.41 X 10-26 J/T$

Generally the equation for magnitude of $B_{int}$ is mathematically given by

$B_{int}=B_{ext}-\frac{h\triangle \sigma}{2 \mu}$

$B_{int}=0.78-\frac{6.6*10^{-34}*34*10^6}{2*1.41*10^{26}}$

$B_{int}=0.78-0.7957$

$B_{int}=-0.015T$
