The lens changes the focal distance of the eye so that you can focus on images/objects.
Answer:
the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.
Explanation:
The magnetic force is given by the expression
F = q v x B
The bold are vectors, where v is the velocity and B is the magnetic field, the product is the cross product whose result is a vector perpendicular to the two vectors (v and B)
From the above, the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.
Even when the change in direction is real and is caused by a centripetal force
For there to be a change in the velocity modulus there must be a force parallel to the velocity direction, generally a force in electrical
Answer:
Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.
The formulas that relate to this are given below:
P1 = P2 (since the pressures are equal throughout).
P2 is the pressure transmitted in the hydraulic system
N.B : P= Force/ Area
Therefore we have
F1/A1 = P2
F1= the force exerted by the driver = 100N
P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm
(1) ionic, (2) metallic, (3) covalentnetwork, and (4) molecular
