Inverse beta decay, the subatomic interaction by which an electron and a proton are "crushed" into a neutron, the process in whi

gogolik [260]

Options:

A. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming

B. the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

C. the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and are transforming

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

E. is the process where the recoil, on a massive scale of an entire stellar nucleus, are pushing out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

Answer:

D. is the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforms

Explanation:

NB: In options A-C, the verb "is" is required as a compliment to the subject "inverse beta decay"

The tenses used also do not align with the subjects.

Option E uses "where" for a process. This is wrong, it should only be used for a physical location

Only option D does not violate any rule of concord.

A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magni

Verizon [17]

Answer:

(a). The magnitude of the net force is $(2.1\times10^{-18}\ N)k$

(b). The magnitude of the net force is $(4.23\times10^{-19}\ N)k$

(c). The magnitude of the net force is $(8.4\times10^{-19}\ N)i+(12.6\times10^{-19}\ N)k$

Explanation:

Given that,

Magnetic field $B=-3.54\times10^{-3}i\ T$

Velocity = 2230j m/s

We know that,

The net force acting on the proton is equal to the sum of electric and magnetic force.

$F=F_{e}+F_{B}$

(a). If the electric field is in the positive z direction and has a magnitude of 5.25 V/m,

We need to calculate the magnitude of the net force acting on the proton

Using formula of net force

$F_{net}=e(E+v\times B)$

Put the value into the formula

$F_{net}=1.6\times10^{-19}(5.25k+2230\times-3.54\times10^{-3}(j\times i))$

$F_{net}=1.6\times10^{-19}(5.25k+2230\times-3.54\times10^{-3}(-k))$

$F_{net}=(2.1\times10^{-18}\ N)k$

(b). If the electric field is in the negative z direction and has a magnitude of 5.25 V/m,

We need to calculate the magnitude of the net force acting on the proton

Using formula of net force

$F_{net}=e(E+v\times B)$

Put the value into the formula

$F_{net}=1.6\times10^{-19}(-5.25k+2230\times-3.54\times10^{-3}(j\times i))$

$F_{net}=1.6\times10^{-19}(-5.25k+2230\times-3.54\times10^{-3}(-k))$

$F_{net}=(4.23\times10^{-19}\ N)k$

(c). If the electric field is in the positive x direction and has a magnitude of 5.25 V/m

We need to calculate the magnitude of the net force acting on the proton

Using formula of net force

$F_{net}=e(E+v\times B)$

Put the value into the formula

$F_{net}=1.6\times10^{-19}(5.25i+2230\times-3.54\times10^{-3}(j\times i))$

$F_{net}=(8.4\times10^{-19}\ N)i+(12.6\times10^{-19}\ N)k$

Hence, (a). The magnitude of the net force is $(2.1\times10^{-18}\ N)k$

(b). The magnitude of the net force is $(4.23\times10^{-19}\ N)k$

(c). The magnitude of the net force is $(8.4\times10^{-19}\ N)i+(12.6\times10^{-19}\ N)k$
