When two permanent magnets are placed adjacent to each other then they will exert magnetic force on each other.
There are four fundamental forces in nature
1. Gravitational force
2. Electromagnetic force
3. Weak Nuclear force
4. Strong nuclear force
So here magnets will exert two fundamental forces on each other <u>Electromagnetic force and Gravity</u>

mass is defined as the composition or amount of substance while we can define weight as gravitational force of earth of the given object
Now when we transport an object from surface of earth to space far away from any planet then the amount of substance or mass will not change while the weight of the substance will decrease to zero because there is no gravity at this position
So we can say
mass = constant and will remain same
Weight = mass * gravity = 0
<u>The weight of the object changes, the mass stays the same</u>
What a great photo ! The answer is 'diffraction'.
Answer:
4.22 m
Explanation:
Una rampa es una máquina que se utiliza para levantar un objeto con una fuerza menor a la que realmente necesitarías. Cuanto mayor sea la longitud de la rampa, menor será la magnitud de la fuerza necesaria para levantar el objeto.
Dado que:
altura de la rampa = 1.5 m, carga = 4900 N, fuerza aplicada = 1633.33 N.
La fórmula de la rampa se da como:
fuerza aplicada * longitud de la rampa = peso de la carga * altura de la rampa
1633.33 * longitud de la rampa = 4900 * 1.5
longitud de la rampa = 4900 * 1.5 / 1633.33
longitud de la rampa = 4.22 m
I expect that they will <em>add</em>, and their effect at every location will be the <em>sum</em> of their individual effects at that location.
For example:
If they're acting at the same point and in opposite directions, the effect will be the same as a single force at that point, with strength equal to their difference, and in the direction corresponding to whichever one is stronger.
