Answer:
A circular pizza has a angle of 360 degrees. When you cut it into 3 equal pieces you divide 360 by 3,you get 120 degrees. And following the conversion of 120 degree into radian you get 2pie/3 radians.
Answer:
Explanation:
The total degree of the circle = 360°
It is divided into 3 equal parts, so each part becomes 360 / 3 = 120°
conversion of 120 degree into radian you get 2pie/3 radians.

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 student bikes 5.00 km East to school in 30.0 min, realizes he forgot his calculator for physics, spends 30.0 min going back going home, and then races back to school in 27.0 minutes.
1.What is the students total distance traveled ?
2. Determine the students average speed ?
3. What is the students total displacement ?
4. Determine the students average velocity ?
Explanation:
Given data
distance = 5km
time taken to travel to school= 30 min
1. the total distance traveled is
from home to school+ school to home+ home back to school
5km+5km+5km= 15 km
2. Determine the students average speed
average speed is the total distance divided by the total time taken
= (5+5+5)/(30+30+27)
= 15/87 km/min
3 What is the student total displacement
the displacement tells how far a place is hence the displacement is 5km (i.e the school is 5km from his home)
4. Determine the students average velocity
a. speed home to school
v= 5/30= 0.166 km/min
b. school back home
v= 5/30= 0.166 km/min
c. speed home to school
v= 5/27= 0.185 km/min
Average velocity = (0.185 + 0.166 + 0.166)/3= 0.517/3= 0.17 km/min
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 student puts a beaker of boiling water where it touches a block of ice.
Which two statements are true?
A. Thermal energy will move from the boiling water to the ice.
B. Thermal energy will move from the air to the ice.
O c. Thermal energy will move from the air to the boiling water.
D. Thermal energy will move from the ice to the air.
O
Answer:
Option (A).
Explanation:
When a hot and a cold objects come in thermal contact with each other,exchange of heat takes place between them until thermal equilibrium is reached.
In this process thermal energy flows from high temperature to low.
Therefore, when a beaker of boiling water comes in touch with a block of ice,
Thermal energy starts flowing from boiling water to block of ice until equilibrium is established.
Option (A) will be the answer.

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.

a girl is 8 years older than her younger sister. The sum of their ages is 64 years, what is her age in years
Answer:
let the age of elder sister = x+8
then let the age of younger sister be x
sum of their ages = 64
according to the question,
x+8+x = 64
2x+8 = 64
2x = 64-8
2x = 56
x = 56/ 2
x = 28
so, the age of younger sister is 28 years
and the age of elder sister is x+8= 28+8= 36years

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.

3. What distance will a car, traveling 65 km/hr, cover in 3.0 hrs? (195 km)
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
And this is your required answer..[tex].[/tex]
