The second major reason for the difference in gravity at differentlatitudes is that the Earth's equatorial bulge (itself also caused by centrifugalforce from rotation) causes objects at the Equator to be farther from the planet's centre than objects at the poles.
Answer:
44200 N
Explanation:
To calculate the average force exerted on the car, we will use the following equation
Where F is the average force, t is the time, m is the mass, vf is the final velocity and vi is the initial velocity of the car.
Replacing t = 0.5s, m = 1300 kg, vf = -2 m/s, and vi = 15 m/s and solving for F, we get
Therefore, the average force exerted on the car by the wall was 44200 N
Answer:
The magnetic force on the wire at the moment is 2 micro-Newton/(Ampere-meter)
Explanation:
Formula for magnetic force is F = qvB*sin(theeta)
and B = μ*I / 2*pi*r
where
q = charge in coulomb
v = velocity
B = magnetic field strength
μ = permeability of free space
I = current
so from here we get B = (4*pi*10^(-7))(5) / 2*pi*0.01 = 0.0001-T
now ,
F = (2mC)*(10)*0.0001*sin(90)
F = 2 micro-Newton/(Ampere-meter)
Answer:
An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
According to Heisenberg's theory we cannot observe the position and velocity of an electron in an orbit, but if they were around the nucleus (in orbit), it would be possible to know its velocity and position, which would be contrary to the principle of Heisenberg So we can say that no electron revolves around a certain orbit around the nucleus, so we can only predict if the electron will be in the right position at the right time.
From there we find two definitions for electron orbital let's see:
- Orbital is considered the region of space, where each electron spends most of its time.
- Orbital is considered the region of space that is most likely to find an electron.
