A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane

a grey kangaroo can lead a distance of 10m on horizontal ground. what is the minimum takeoff speed for such a leap?
show your work please!!
The minimum speed with which a projectile will travel a range is given by the speed when the given range is taken as the maximum range for the given speed
The minimum takeoff speed for such a leap is approximately 9.9 m/s
The known parameter is the distance a grey kangaroo can leap = 10 meters
The required information is the minimum takeoff speed for the leap
Solution:
The path of motion of the kangaroo as they leap is the path of a projectile
The distance of the leap is the range of the projectile
The formula for the maximum range is presented as follows;
[tex]Maximum \ range, R = \mathbf{ \dfrac{v_0^2 }{g}}[/tex]
v₀ = The initial speed of the kangaroo
g = The acceleration due to gravity ≈ 9.81 m/s²
The minimum speed to reach a maximum range of, R = 10 meters is found as follows;
[tex]\mathbf{ Maximum \ range, R} = 10 \, m = \dfrac{v_0^2 }{9.81 \ m/s^2}[/tex]
Therefore;
v₀² = 10 m × 9.81 m/s² = 98.1 m²/s²
v₀ = √(98.1 m²/s²) ≈ 9.9 m/s
The minimum takeoff speed for the kangaroo to leap 10 meters on horizontal ground, v₀ ≈ 9.9 m/s

Benjamina started her walk from the front door of her ground-floor apartment. She walked 6 meters to the corner of the building and then turned the corner and walked 10 meters to her friend’s apartment. Identify the difference between the distance she walked and her displacement.
Answer:
The change in her position (from beginning to end), along with the direction, is considered her displacement.
Explanation:
Answer:
The change in her position ( from beginning to end), along with the direction, is considered her displacement. This value is a measurement and a direction. The total distance along the path from her starting point to her endpoint is considered her distance. This value is a measurement only.

In Hindu chronology, the longest time measure is a para. One para equals 311 040 000 000 000 years. Calculate this value in megayears, hours and in seconds. Write your answers in scientific notation.
A para equals [tex]3.110\times 10^{8}[/tex] megayears, [tex]2.725\times 10^{18}[/tex] hours and [tex]9.809\times 10^{21}[/tex] seconds, respectively.
This is an unit conversion problem, in this question we need to convert a value in Hindu units into SI units. A megayear equals [tex]10^{6}[/tex] years, a year equals 8760 hours and a hour equals 3600 seconds. Now we proceed to perform all required conversions:
Megayears
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{1\,Myr}{10^{6}\,yr}[/tex]
[tex]x = 311040000\,Myr[/tex]
[tex]x = 3.110\times 10^{8}\,Myr[/tex]
Hours
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{8760\,h}{1\,yr}[/tex]
[tex]x = 2.725\times 10^{18}\,h[/tex]
Seconds
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{8760\,h}{1\,yr} \times \frac{3600\,s}{1\,h}[/tex]
[tex]x = 9.809\times 10^{21}\,s[/tex]
A para equals [tex]3.110\times 10^{8}[/tex] megayears, [tex]2.725\times 10^{18}[/tex] hours and [tex]9.809\times 10^{21}[/tex] seconds, respectively.

Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.
What are natural sciences?Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.
These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

In vector diagrams, what does the length of the arrow tell you?
Answer:
The length of the arrow tells you the size of the quantity in the vector diagram.
The direction of the arrow simply tells you the direction
Answer and Explanation:
A vector in this sense is a thing that has both magnitude (length) and direction.
Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.
This doesn't give any information about where you started or any information about where you ended up after those 2 hours.
This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.
Velocity is a vector.
Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.
The length of the arrow represents all of the possible places you could be after a two hour walk.
Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.
