What are some examples of how we use science in or daily lives?
Answer: Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.
Explanation:
Answer:
Science is at work in almost every part of our lives from the computer we use to the foods that we consume. For example take the yellow corn that we are use to eating it is actually a result of bio-agriculture.
Explanation:
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

Explanation:
A wildbeest runs with an average speed of 4.0m/s for 15s . What was the distance travelled in meters
Answer:
60.0m im sorry if im wrong but this is what i got
Explanation:
Answer:
The Answer Is 60 m
Explanation:
Distance d = ?
Time t = 15 s
Average speed vavg = 4.0 m/s
You can rearrange the equation vavg = d/t to solve for distance travelled d.
vavg = d/t
d = vavgt
= (4.0 m/s) (15s)
= 60 m

An airplane flies with an unknown velocity due east. The plane
is experiencing wind of 12 m/s due north which produces a
resultant velocity of 35.11 m/s northeast. Determine the
unknown velocity produced by the plane engines.
Answer:
32.99m/s
Explanation:
Using the formula for calculating the resultant velocity according to Pythagoras theorem
R² = 12²+x²
35.11² = 12²+x²
X² = 35.11²-12²
X² = 1232.7121-144
X² = 1088.8121
X = √1088.8121
X = 32.99m/s
Hence the unknown velocity produced by the plane engines is 32.99m/s
The unknown velocity produced by the plane engines will be "32.99 m/s".
Given:
Resultant velocity,
R = 35.11 m/sWind speed,
12 m/sBy using the Pythagoras theorem, we get
→ [tex]R^2= 12^2+x^2[/tex]
→ [tex]35.11^2=12^2+x^2[/tex]
→ [tex]1232.712=122+x^2[/tex]
→ [tex]x^2= 1099.8121[/tex]
→ [tex]x = \sqrt{1088.8121}[/tex]
→ [tex]= 32.00 \ m/s[/tex]
Thus the answer above is right.

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.
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
