Answer:
well it depends of the distance, but u get your frequency and u times it by a round number if im correct
Explanation:
b. chemical reactions
c. resistance
d. the movement of electric charge
Answer:
d. the movement of electric charge
Explanation:
Voltage source is used to provide constant voltage difference across the ends of a given conductor where it is connected
Now when voltage source is connected across the conductor we can say that due to constant voltage difference there would be a constant current will maintain in the conductor
It is given by
now since the voltage difference and resistance both are constant so current will be same in the circuit
So here the flow of charge will remain constant due to voltage source
So correct answer would be
d. the movement of electric charge
1 m/s2
4 m/s2
2 m/s2
Answer :
a = 1 m/s^2
Explanation:
Given information
Net force is a constant
The mass of the truck is
Initial acceleration = 2 m/
The mass of the truck is increased twice as much
= ma
= a
a=
a = 2/2
a = 1 m/
This is a conceptual problem, I’ll try to upload a picture:
Answer:
2.62A
Explanation:
Given
V = 0.43 V
I = 3.1 A
Then, V = IR, R = V/I
R = 0.43/3.1
R = 0.14 Ω
The induced emf = dB/dt * A
So that, dB/dt = emf/A
Since dB/dt is constant then Emf/A(circle) = Emf/A square
So Emf (square)/Emf (circle) = A square / A circle
A circle = πr². The perimeter of the square is 2πr which also is the circumference of the square.
Since the perimeter is 2πr, then each side would be πr/2. Thus, the area of the square would be, (πr/2)² = π²r²/4
So A square/Acircle = (π²r²/4) / πr² = π/4 = 0.79
this means that, emf square = emf circle * 0.79
emf square = 0.43*0.79 = 0.34V
I = V/R
I = 0.34/0.13
I = 2.62A
The only way to increase the time of flight is to increase the height traveled by the projectile to 2h.
The given parameters;
The time of flight of the projectile is calculated as follows;
where;
is the initial vertical velocity of the projectile = 0
Thus, the only way to increase the time of flight is to increase the height traveled by the projectile to 2h.

Answer:
d)
Explanation:
a) decreasing the mass to m/2. FALSE. Mass doesn't influence the equations of accelerated motion.
b) decreasing the height to h/2. FALSE. From a lower initial height the projectile will reach the ground faster.
c) increasing the initial horizontal velocity to 2vx. FALSE. The horizontal and vertical components are independent, and time of flight is dependent only on vertical conditions in this case.
d) increasing the height to 2h. TRUE. From a higher initial height the projectile will reach the ground later.
