Two strong permanent magnets are placed one inch apart. which two fundamental forces will most affect them. weak and gravity strong and electromagnetic gravity and strong electromagnetic and gravity an object is transported from earth to deep space, far from any stars or planets. what happens to the mass and weight of the object? both the weight and mass of the object change. neither the weight nor the mass of the object change. the weight of the object changes, the mass stays the same the mass of the object changes, the weight stays the same

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 Electromagnetic force and Gravity

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

The weight of the object changes, the mass stays the same

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
