Answer:
Distance: 4.6km Displacement= -0.2km
Explanation:
Total distance: 1.5+2.4+0.7= 4.6 km
Displacement: 1.5-2.4+0.7= -0.2km
The displacement may also be 0.2km, it just depends on if it wants it negative or not.
Tiana displacement is 0.2 km in the opposite direction, while her distance covered is 4.6 km
Given that Tiana's original direction be the positive direction.
Displacement is a vector quantity. That is, we will consider both the magnitude and direction.
As Tiana jogs 1.5 km along a straight path and then turns and jogs 2.4 km in the opposite direction, Her displacement = 1.5 - 2.4
As She then turns back and jogs 0.7 km in the original direction,
Displacement = 1.5 - 2.4 + 0.7
Displacement = - 0.2 km ( that is, in the opposite direction.)
Distance is a scalar quantity. That is, we will only consider the magnitude.
Tiana total distance = 1.5 + 2.4 + 0.7
Total distance = 4.6 km
Therefore, her displacement is 0.2 km in the opposite direction, while her distance covered is 4.6 km

A bear is sitting at rest on a tricycle. The bear then starts to accelerate uniformly at a rate of 2.5
m/s2. How long will it take the bear to reach a velocity of 15 m/s?
Answer:
15 m/s
Explanation:
Initial velocity, u = 0
Acceleration of bear, a = 2.5 m/s²
We need to find time taken by bear to reach a velocity of 15 m/s.
Acceleration is equal to the rate of change of velocity. So,
[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{15-0}{2.5}\\\\t=6\ s[/tex]
It will take 6 seconds to reach a velocity of 15 m/s.

What are aerial plants
Answer:
Aerial plants are plants that lives in air or wind the wind serves as the water of the plants. Most aerial plants are found in tropical and equatorial regions of the world. In evergreen rain forests, the foliage is so thick that some plants have evolved aerial roots to allow them to absorb more sunlight. The development of aerial roots is
thus an evolutionary process.Aerial roots are often thick and spread around the parent tree. The Banyan tree can have several aerial roots as it gets older.

what are the principals behind Newtons first and third law?
Answer:
First law: An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force. (i.e. Objects in motion tend to stay in motion. Objects at rest tend to stay at rest.)
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

A 100-m long ski lift carries skiers from a station at the foot of a slope to a second
station 40 m above. What is the IMA of the lift?
40
Answer:
12
Explanation:
Explanation:
The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (Fw), and the input force Fi applied to move the object along the slope:
ima= {Fw}÷{Fi},
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope ll , i.e.
Fw h = Fi L
From this we find
{Fw}÷{Fi} = {L}÷{h}
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:
ima= {L}÷{h} = {100m}÷{40m}=2.5

Explanation:
In the stratosphere the ozone layer absorbs and scatters the solar ultraviolet radiation. In the mesosphere meteors burn up. In the thermosphere aurora and satellites occur. In the ionosphere overlapping into the mesosphere and thermosphere occur.
Answer:
Thermospheric temperatures increase with altitude due to the absorption of highly energetic solar radiation. Radiation causes the atmosphere particles in this layer to become electrically charged, enabling radio waves to be refracted and thus be received beyond the horizon. This is how solar radiation can affect the thermosphere.

If mass A is 1.0 kg, mass B is 5.0 kg, and the frictional pulley has a mass of 0.5 kg and a radius of 0.15 m, what is the velocity of A and B at 0.5 seconds?
a. A = 1.72 m/s, B = 0.22 m/s
c. A = 0.22 m/s, B = 1.72 m/s
b. A = 3.14 m/s, B = -3.14 m/s
d. A = -3.14 m/s, B = 3.14 m/s
Answer:
b. A = 3.14 m/s, B = -3.14 m/s
Explanation:
Assuming this refers to an Atwood machine, draw free body diagrams for each mass.
For mass A, there are two forces: tension T₁ pulling up and weight m₁g pulling down.
For mass B, there are two forces: tension T₂ pulling up and weight m₂g pulling down.
For the pulley, there are two torques: tension T₁r pulling counterclockwise and tension T₂r pulling clockwise.
Sum of forces on A in the +y direction:
∑F = ma
T₁ − m₁g = m₁a
T₁ = m₁g + m₁a
Sum of forces on B in the -y direction:
∑F = ma
m₂g − T₂ = m₂a
T₂ = m₂g − m₂a
Sum of torques on the pulley in the clockwise direction:
∑τ = Iα
T₂r − T₁r = (½ mr²) (a/r)
T₂ − T₁ = ½ ma
Substitute:
m₂g − m₂a − (m₁g + m₁a) = ½ ma
m₂g − m₂a − m₁g − m₁a = ½ ma
m₂g − m₁g = m₂a + m₁a + ½ ma
g (m₂ − m₁) = a (m₂ + m₁ + ½ m)
a = g (m₂ − m₁) / (m₂ + m₁ + ½ m)
a = (9.8 m/s²) (5.0 kg − 1.0 kg) / (5.0 kg + 1.0 kg + ½ (0.5 kg))
a = 6.272 m/s²
Given:
v₀ = 0 m/s
a = 6.272 m/s²
t = 0.5 s
Find: v
v = at + v₀
v = (6.272 m/s²) (0.5 s) + 0 m/s
v = 3.14 m/s
Therefore, mass A will rise at 3.14 m/s, and mass B will fall at 3.14 m/s.
