Probably not strong because the car weights 2000 more than the rope
Hey !
The anwer is : A.
Because an object is moving at constant speed ( whic is distance/time) when the distance and the time grow directly proportional . (it means when the distance is getting bigger,then the time is getting bigger equally).
Answer:
The planet that is farther from the star must have a time period greater.
Explanation:
We can determine the ratio of the period's planet with the radius of the circular orbit in the star's equatorial plane:
(1)
Where:
r: is the radius of the circular orbit of the planet and the star
T: is the period
G: is the gravitational constant
M: is the mass of the planet
From equation (1) we have:
(2)
Where k is a constant
From equation (2) we have that of the two planets, the planet that is farther from the star must have a time period greater.
I hope it helps you!
Answer: 0.1 m, 0.0583 m
Explanation:
We are given that:
Frequency for throat= 800 Hz
Frequency for mouth= 1500 Hz
Sound speed= 350 m/s
We have to find the corresponding lengths.
We have
f=
or L=
For the throat= L= = 0.1 m
For the mouth= L= = 0.0583 m
