Answer:
L = 1.023 H
Explanation:
given,
radius of the cylindrical solenoid = r = 0.6 m
Number of turns = N = 600
Length = l = 0.5 m
Current in the cylindrical solenoid = 15 A
Inductance in the coil = ?
using formula
L = 1.023 H
the inductance L of the coil is = 1.023 H
E = q/r^2
where r is perpendicular distance between the point and source charge
Ex = E cos theta
Ey = E sin theta
take theta angle between horizontal and line joining the point charge and the point
The first one can consist of three touchdowns for the first team and a feild goal for the second team. The second one would consist of two touchdowns and a field goal for the first team and a field goal and a two point conversion for the second team. They are both possible but 21-3 is more likley because it dont consist of a two point conversion which is rare to happen in the first place.
Note: The touchdown points were saying that the made the kick
Answer:
The horizontal range will be
Explanation:
We have given initial speed of the shell u =
Angle of projection = 51°
Acceleration due to gravity
We have to find maximum range
Horizontal range in projectile motion is given by
So the horizontal range will be
a). is true. <span>All motion is relative to a frame of reference. That's a fancy
way of saying that whenever you talk about a distance, an acceleration,
or a speed, they're always compared to something. Many surprising
things come out of this:
-- There's no such thing as "how fast is it <u>really</u> moving".
-- There's no such thing as "how high is it <u>really</u>".
-- There's no such thing as "<u>really</u> moving" or "<u>really</u> at rest".
What about quantities where you use distance or motion to calculate them ?
Like . . . . .
Potential energy . . . . . (mass) x (gravity) x (<u>height</u>)
Kinetic energy . . . . . (1/2) (mass) (<u>speed</u>)²
Momentum . . . . . (mass) x (<u>speed</u>) .
Yep, that's right. Those things are all relative to a frame of reference too;
different observers can get different answers,and they're all correct ... for
their own frame of reference.
Simple example:
You're flying in a passenger jet to visit your grandma.
In the frame of reference of somebody on the ground, you're moving at
400 miles per hour.
In the frame of reference of the pilot or the person sitting next to you,
you are at rest, and you can listen to your pod or read a book ... (or
maybe you're <em>heavily</em> at rest and taking a nap :-).)
