Answer:
Le calcul du courant se fait avec deux éléments : la tension et la valeur de la résistance. Courant (A) = tension (V) / résistance (Ohm) ce qui donne la formule I = U/R.

Answer:
= F Δt / m
Explanation:
The impulse theorem and momentum is
I = Δp
F Δt = m - m v₀
Before touching the ball is without movement, the force is represented by the kinetic energy of the club when it reaches the bottom of the path, so if this force is constant, the time [or the duration of the blow is directly proportional to the speed that the ball acquires.
= F Δt / m
The higher this speed, the greater the distance traveled.
The image distance is 59.2 cm and the image is real and small.
<h3>
Image distance</h3>
The distance of the image formed by the convex or converging lens is determined by applying the following lens equation.
1/f = 1/u + 1/v
where;
- f is the focal length = 34 cm
- u is the object distance = 80 cm
- v is the image distance = ?
1/v = 1/f - 1/u
1/v = 1/34 - 1/80
1/v = 0.0294 - 0.0125
1/v = 0.0169
v = 1/0.0169
v = 59.2 cm
Thus, the image distance is 59.2 cm and the image is real and small.

Answer:
Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.
Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body. I hope this helps you
