Answer:
Mass and height
Explanation:
Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about
Which is represented as;
stands for gravitational potantial energy,
m stands for mass of object,
g is the gravitational constant and
h is the height.
Here we see that mass of object and height is directly proportional to the gravitational potential energy.
That means increasing in mass and height will result in increasing gravitational potential energy.
Answer:
τ ≈ 0.90 N•m
F =
Explanation:
I = ½mR² = ½(10)0.5² = 1.25 kg•m²
α = ω²/2θ = 3.0² / 4π = 0.716... rad/s²
τ = Iα = 1.25(0.716) = 0.8952... ≈ 0.90 N•m
τ = FR
Now we have the unanswered question of reference frame.
80° from what?
If it's 80° from the radial
F = τ/Rsinθ = 0.90/0.5sin80 = 1.818... ≈ 1.8 N
If it's If it's 80° from the tangential
F = τ/Rcosθ = 0.90/0.5cos80 = 10.311... ≈ 10 N
There are an infinite number of other potential solutions
It would be B because it makes science to the topic
Answer:
Magnitude of the hiker's total displacement = 3.5 km
Angle and direction of the hiker's total displacement = 22 degree south of west
Explanation:
The first Displacement in vector form is
= -4.5 cos 45i +4.5 sin 45j
= -3.182i + 3.182j
The second Displacement in vector form is
= -4.5j
The total displacement is ,
= -3.182i + 3.182j - 4.5j
=-3.182i-1.318j
The magnitude of the displacement is,
s= 3.444
The direction is,
