The problem can be solve using the formula
τ=r F sin(θ)
Where
τ is the torque,
r is the distance from where the pivot is to where the force
is,
F is the force exerted, and
θ is the angle between the force and radius
τ=(0.15m) (150N) sin(30) = 11.25 Nm

Answer:
The terrestrial planets in order from smallest to largest are :
Explanation:
Answer:
The surface charge density on planes A and B respectively is
and
Explanation:
From the question we are told that
The electric field in region to the left of A is
The direction of the electric field is left
The electric field in the region to the right of B is
The direction of the electric field is right
The electric field in the region between the two planes is
The direction of the electric field is right
Let the surface charge density on planes A and B be represented as
From the question we see that
Generally the electric to the right and to the left is due to the combined electric field generated by plane A and B so
=>
Generally the electric field at the middle of the plane A and B is due to the diffencence in electric field generated by plane A and B
i.e
=>
=>
From equation 1
=>
So
=>
Explanation:
Using,
S = vi*t + 1/2*a*tr^2
vi = initial velocity = 0 m/s
S = 1/2 * 9.8 * tr^2
= 4.9tr^2.
S = vf * (ta - tr)
4.9tr^2 = 330 * (9.3 - tr)
4.9tr^2 - 3069 + 300 * tr)
Using general quadratic equation,
tr = 8.93 s.
S = 4.9 * (8.93)
= 390.75 m.
B.
Therefore,
S = 4.9 * (9.3)^2
= 423.8 m.
The height of the cliff would be overestimated.
Answer:
Proxima Centauri is a small, low-mass star located 4.244 light-years (1.301 pc) away from the Sun in the southern constellation of Centaurus. Its Latin name means the "nearest [star] of Centaurus". This object was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun.
