Answer:
If x₁=12 cm then k=1.7985 N/m
If x₂=15 cm then k=1.4388 N/m
Explanation:
Hanging mass= 22 g=0.022 kg
Acceleration due to gravity g=9.81 m/s²
If x₁=displacement= 12 cm=0.12 m
k= spring constant
∴k = 1.7985 N/m
If x₂=15 cm=0.15 m
Force of the hanging mass is same however the spring constant will change
∴k = 1.4388 N/m
As the mass is not changing the spring constant has to change. That means that here there are two spring one with k=1.7985 N/m and the other with k= 1.4388 N/m
Hi, time is independent variable. It's stands alone and isn't change by anything.
Temperature is dependant variable (depends on time)
Answer:
models are only used by scientists
If gravity had no effect on a ball after you threw it ... and there also
were no air to slow it down ... then the ball would continue traveling
in a straight line, in whatever direction you threw it.
That's the heart and soul of Newton's laws of motion ... any object
keeps moving at the same speed, and in a straight line in the same
direction, until a force acts on it to change its speed or direction.\
If you threw the ball horizontally, then it would keep moving in the
same direction you threw it. But don't forget: The Earth is not flat.
The Earth is a sphere. So, as the ball kept going farther and farther
in the same straight line, the Earth would curve away from it, and it
would look like the ball is getting farther and farther from the ground.
Answer:
Explanation:
Let time taken by Jada in driving be t hour .
distance travelled by jada = 55 t
a )
Time of drive by destiny = t - 10 min
= t - .167 hour
distance of travel by destiny = 70 ( t - .167 )
Total distance = 45 miles
55 t + 70 ( t - .167 ) = 45
55t + 70 t - 11.69 = 45
125 t = 56.69
t = .453 hour = 27.21 minutes
b )
distance travelled by Destiny = 70 ( t - .167 )
70 ( .453 - .167 )
= 20.02 miles .
