Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
Explanation:
Answer:
23.5 mV
Explanation:
number of turn coil 'N' =22
radius 'r' =3.00 cm=>
0.03m
resistance = 1.00 Ω
B= 0.0100t + 0.0400t²
Time 't'= 4.60s
Note that Area'A' = πr²
The magnitude of induced EMF is given by,
lƩl =ΔφB/Δt = N (dB/dt)A
=N[d/dt (0.0100t + 0.0400 t²)A
=22(0.0100 + 0.0800(4.60))[π(0.03)²]
=0.0235
=23.5 mV
Thus, the induced emf in the coil at t = 4.60 s is 23.5 mV
Answer:
Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass . Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.
Explanation:
The frequency at which the body vibrates breaks is natural frequency. The glass with her voice because the frequency of her voice matches the natural frequency of the glass.
<h3>What is the natural frequency?</h3>
When there is no external force acting on the body unless the body vibrates is known as the natural frequency of vibration.it is denoted by 
.
when the frequency of a body matches the natural frequency a condition occurs known as resonance.
To learn more about the natural frequency refer to the link;

Answer:
5.09 Pa
Explanation:
Area of the circle = πr²
The diameter is given, so 100/2 = 50 m is the radius.
π x 50² = 7854 m²
Pressure = force/area
Pressure = 40000/7854
Pressure = 5.09 Pa
Hope this helps!
