The metric unit of force is _____.
2 answers:
Answer:
The metric unit of force is the Newton (N)
Explanation:
Force is defined as the product between mass and acceleration:
The mass of an object (m) is measured in kilograms (kg), while the acceleration (a) is measured in meters per squared second (m/s^2). So, the metric unit of the force is
This unit is called Newton, its symbol is N, and this is the metric unit of the force.

Metal bar is aligned along East- West direction and it is dropped vertically down
So its velocity is along -Z direction,
Now the Earth's magnetic field is towards north so its towards +Y direction
now we have formula for force on a moving charge
v = - z direction
B = + y direction
now by the above formula
So force is towards East
so all positive charge is towards East end
Answer:
0.51 m
Explanation:
Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.
Kinetic energy, KE=½kx²
Where k is spring constant and x is the compression of spring
Potential energy, PE=mgh
Where g is acceleration due to gravity, h is height and m is mass
Equating KE=PE
mgh=½kx²
Making x the subject of formula
Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then
