Answer:
Explanation:
Given an LC circuit
Frequency of oscillation
f = 299 kHz = 299,000 Hz
AT t = 0 , the plate A has maximum positive charge
A. At t > 0, the plate again positive charge, the required time is
t =
t = 1 / f
t = 1 / 299,000
t = 0.00000334448 seconds
t = 3.34 × 10^-6 seconds
t = 3.34 μs
it will be maximum after integral cycle t' = 3.34•n μs
Where n = 1,2,3,4....
B. After every odd multiples of n, other plate will be maximum positive charge, at time equals
t" = ½(2n—1)•t
t'' = ½(2n—1) 3.34 μs
t" = (2n —1) 1.67 μs
where n = 1,2,3...
C. After every half of t,inductor have maximum magnetic field at time
t'' = ½ × t'
t''' = ½(2n—1) 1.67μs
t"' = (2n —1) 0.836 μs
where n = 1,2,3...
Answer:
Its acceleration is 1.5 
and the distance it has covered is 150 m.
Explanation:
Acceleration is a quantity that indicates the variation in speed of a moving body as time passes. That is, acceleration relates changes in velocity with the time in which they occur.
The average acceleration is defined as the relationship between the variation or change in the speed of a mobile and the time used in said change:
In this case:
- change in speed= final speed - initial speed= 15 m/s - 0 m/s= 15 m/s
- time= 10 s
Replacing:
and solving you get:
<u><em>acceleration= 1.5 </em></u><u><em></em></u>
Speed is a quantity that expresses the relationship between the space traveled by an object and the time used for it. This is:
So the distance can be calculated as:
distance= speed* time
In this case:
Replacing:
distance= 15 m/s* 10 s
and solving you get:
<u><em>distance= 150 m</em></u>
<u><em>Its acceleration is 1.5 </em></u><u><em> and the distance it has covered is 150 m.</em></u>
The independent variable is the one thing that changes in the experiment, the dependent is what you are measuring, and controlled is all the things you keep the same and never change. So for the first one I=different tire trends (change it each time), D=breaking distance (what you are measuring) and C=use the same car, same brand of tires, same brand of brakes, run cars on same surface etc..
Hope this helps!
Answer:
The trucks must have equal masses that is they must have same load.
Explanation:
Momentum refers to the product of the mass of the object and velocity.
As momentum has both magnitude and direction, it is a vector quantity.
In the given problem, it is given that after the collision, the trucks move at more than half the original speed of the moving truck. Therefore, the trucks must have equal masses that is they must have the same load.
Answer:
A. Moving the mass from Point C to B, although it involves a greater distance, requires less force to do the same amount of work.
Explanation:
The amount of work will be the same either way. By going from C to B, the mover will exert less force over a greater distance, which is easier than exerting a greater force over a shorter distance.
