2. A child observes a caterpillar walking on a window sill. The caterpillar walks 18 cm to the left, then 6 cm to
the right, then 10 cm to the left.
b. What is the displacement of the caterpillar?
Answer:
D = 8 cm
Explanation:
It is given that, the caterpillar walks 18 cm to the left, then 6 cm to the right, then 10 cm to the left.
We need to find the displacement of the caterpillar. The attached figure shows the path traveled by the caterpillar. A is the initial position, then it reaches B and finally it reaches C.
Let right side is positive and left is negative. We know that,
Displacement = final position - initial position
= C - A
= -10-(-18)
= 8 cm
Hence, the displacement of the caterpillar is 8 cm.

Malia has developed Type II Diabetes. When she eats, her body
does not release the proper amount of insulin needed to balance
her blood sugar (glucose) levels. Which life function is most
threatened by Malia's disease?
Select one:
a. Growth
b. Movement
c. Metabolism
d. Excretion
Answer:
The correct option is c.
Explanation:
Metabolism is a sum of anabolic and catabolic reactions. The body's inability to produce/synthesize enough insulin is the cause of type II diabetes. Generally, metabolism is the process in which most compounds (proteins, carbohydrates and lipids) are produced (anabolism) or broken down (catabolism) in the body. Insulin is a protein that can be produced in less amount due to metabolic disorder in the body.
Maria's disease means she already has an exponentially high amount of blood sugar against the required insulin to balance it out, hence the disease already slowed down her rate of metabolism (catabolism) of blood sugar EXCEPT she decides to increase of metabolism by medication and exercise.

A sports car accelerates at 2.80 m/s2 along a straight road. At t1 = 5.00s and t2 = 5.50 s it passes two marks that are 35.0 m apart. What is the car's velocity at t0 = 0 s?
Explanation:
Using kinematics,
s = ut + 0.5at².
We have s = 35.0m, t = 0.50s, a = 2.80m/s².
Substitute in the variables, we have u = 69.3m/s.
This u is only the initial velocity at t1. To find the velocity at t0, we apply a different kinematics equation with different values:
We have t = 5.00s, a = 2.80m/s², v = 69.3m/s.
Using kinematics,
v = u + at.
Substitute in the variables, we have u = 55.3m/s.
Hence the car's initial velocity is 55.3m/s.

Answer:
[tex] \boxed{\sf Distance \ travelled \ by \ car = 195 \ km} [/tex]
Given:
Speed = 65 km/hr
Time = 3.0 hrs
To Find:
Distance
Explanation:
Distance = Speed × Time
= 65 × 3
= 195 km
GiveN:
Speed of the car = 65 km/hrTime taken = 3 hourTo FinD:
We have to find the distance travelled by the body?We know that, Distance is the product of speed of the body and the time taken in the same system of units. Then,
⇛ Distance = Speed × Time
⇛ Distance = 65 km/hr × 3 hrs
⇛ Distance = 195 km

If your car is going 19 m/s at the beginning of the block (250 meters long), and your acceleration is 3.9
m/s?, how fast are you going at the end of the block?
Answer:
48 m/s
Explanation:
Given:
Δx = 250 m
v₀ = 19 m/s
a = 3.9 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (19 m/s)² + 2 (3.9 m/s²) (250 m)
v ≈ 48 m/s

A car capable of a constant acceleration of 3.72 m/s^2 is stopped at a traffic light. When the light turns green, the car starts from rest with this acceleration. At the very same moment, a truck traveling with constant velocity 13.8 m/s passes the car. As the car’s velocity increases, it will eventually move faster than the truck and later overtake it. How far from the light will the car catch up with the truck?
Explanation:
Let t be the time it takes for the car to catch up with the truck.
Using kinematics equations,
Distance by car = ut + 0.5at² = 0 + 0.5 * 3.72 * t².
Distance by truck = 13.8 * t.
Since these distances have to be equal, we have:
0.5 * 3.72 * t² = 13.8t, 1.86t² = 13.8t, t ≈ 7.42s.
Hence the distance is 13.8 * (7.42) ≈ 102.4m.

The chart describes four objects experiencing one or more frictional forces. Which statement explains the type of friction acting on each object?
a. The bike has rolling friction, the sled and the motorcycle have sliding friction, and the elephant has static friction.
b. The bike and sled have sliding friction, and the motorcycle and elephant have static friction.
c. The bike has static friction, the sled and elephant have sliding friction, and the motorcycle has rolling friction.
d. The bike and motorcycle have rolling friction, the sled has static friction, and the elephant has sliding friction.
Answer:
A
Explanation:
I took the test
Rolling friction is demonstrated by a ball or wheel rolling across the ground. Sliding friction is the other form of friction. Because just one side of the body is in contact with the surface, there is a restriction on the body's ability to move. Thus, option A is correct.
What explains the type of friction acting on each object?When something is sitting on a surface, static friction affects it. Because sliding friction is less powerful than static friction, moving a piece of furniture over the floor is simpler once it is moving than before.
Friction that occurs when a moving fluid is positioned between two bodies and an object slides along the surface. Rolling When a thing rolls over another surface, friction is created.
Therefore, The bike has rolling friction, the sled, and the motorcycle have sliding friction, and the elephant has static friction.
