Answer: Gravity
Explanation:The sun may have a lot of gravitational pull but the further away the less it has, meaning planets like uranus or neptune take a long time to orbit around the sun.
The distance travelled by the object in the time interval of 3 second is 44.15m
The airresistance would try to decrease the acceleration and thus would decrease the distance the ibject has fallen in 3 seconds.
Explanation:
The object is falling vertically down. Hence the acceleration would be replaced by the acceleration due to gravity "g".
We know that distance "s"= ut +1/2*g*t²
where u- initial velocity of the object
g- acceleration due to gravity= 9.81m/s²
t- time period
Since the object is falling from initial rest position hence u=0
thus the equation reduces to 1/2gt²
S=1/2*(9.81)(3)²
Thus the distance =44.145 m(approximately 44.15 m)
If a small amount of air resistance is present in between it would obstruct the falling of the object. hence, in turn, would oppose "g".
This opposition to "g" would decrease the acceleration and thus body would travel less distance in the same time frame i.e. 3 sec
Answer:
You're going 3.2 meters per second.
Explanation:
Answer:
Magnetic flux,
Explanation:
Given that,
Number of turns in the solenoid, N = 250
Current in the solenoid is, I = 9 A
Radius of the solenoid, r = 0.075 m
Length of the solenoid, l = 0.14 m
The magnetic flux is given by :
B is the magnetic field
A is the area of cross section
So, the magnetic flux through the circular cross-sectional area at the center of the solenoid is . Hence, this is the required solution.
