The gravitational force between two objects may be calculated through the equation,
F = Gm₁m₂ / d²
where G is 6.67 x 10^-11 m³/s²kg
Substituting the known values to the equation,
F = (6.67 x 10^-11 m³/s²kg)(5.0 kg)(5.0 kg) / (2.5 m)²
F = 2.668 x 10^-10 N
As stated, the impulse and momentum definitions will be used to later find the value of time through the force of gravity. According to the theory, the impulse formula is given as,
Here,
F = Force
Change in time
Now using the impulse theorem we have that,
Change in Impulse = Change in momentum
(1)
The change in momentum is given as
The force due to gravity is through the Newton's second law
Here,
m = mass
g = Acceleration due to gravity
Substitute the value in (1)
Therefore it will take 0.51s.
Answer:
With the equation:
sin T = l / a (*)
note that the width of the central diffraction maximum is inversely proportional to the width of the slit. If we increase the width size, a, the angle T at which the intensity first becomes zero decreases, resulting bin a narrower central band.
Explanation:
Answer:
Explanation:
mass of car, m = 1000 kg
initial velocity, u = 20 m/s
final velocity, v = 0 m/s
distance, s = 120 m
Let a be the acceleration of motion
use third equation of motion
v² = u² + 2 as
0 = 20 x 20 + 2 x a x 120
a = - 1.67 m/s²
Let F be the force
Force, F mass x acceleration
F = - 1000 x 1.67
F = - 1666.67 N
The direction of force is towards south and the magnitude of force is 1666.67 N.
Answer:
X, Y, Z, W
Explanation:
W has a current of 0 so it has no magnetic field.
X has the most loops (besides W) and the most current so it is the strongest.
Y and Z are the same except Y has more loops so it is stronger than Z.
