Answer from: TH3L0N3W0LF

correct answer is option d) 13 V and 0.46 A

Explanation:

given,

primary coil,

Number of turns N₁ = 1300

Voltage of the primary coil V₁ = 120 V

Current in the primary coil, I₁ =0.05 A

secondary coil,

Number of turns coil N₂ = 140

voltage calculation,

$\dfrac{V_1}{V_2} = \dfrac{N_1}{N_2}$

$V_2=V_1\times \dfrac{N_2}{N_1}$

$V_2=120\times \dfrac{140}{1300}$

V₂ = 13 V

current calculation:

$\dfrac{I_1}{I_2} = \dfrac{N_2}{N_1}$

$I_2=I_1\times \dfrac{N_1}{N_2}$

$I_2=0.05\times \dfrac{1300}{140}$

I₂ = 0.46 A

hence, correct answer is option d) 13 V and 0.46 A

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
