Answer:
D. Electromagnetic Induction.
Explanation:
Answer
The type of boundary formed when lithospheric plates collide is called Convergent boundary
Explanation
When plates of the lithosphere collide, they form a sub-duction zone where the denser plate will be subdued underneath the less dense one. The one subdued later melts and get destroyed. This boundary occurs when; ocean crust meets ocean crust, when oceanic and continental crust meet and where continental crust meets continental crust.
Answer:
a.Electric force exerted on one charged sphere, by another charged sphere.
Explanation:
Coulomb's Law describes the electric force between two objects. It is given by the following formula:
The magnetic field surrounding a current carrying conductor is described by Ampere's Law.
Amount of heat generated by a high current flow in a resistor can be described by P = VI
Voltage induced in a coil by a constant magnetic field is described by Faraday's Law.
The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)
<u>Explanation:</u>
Given data
Amplitude 0.02 m , Frequency= 440 Hz ,Speed = 330 m/s
The equation format is written as,
y = A sin ( k x – ω t)
We need the value of A, k, x -ω t
<u>1. Find the k value</u>
v = f ×λ
330 = 440×λ
k = 2π×λ
k = 880 π /330 m-1
440 ×2π = w
<u>2. Find the ω value</u>
f×2π =ω
ω
= 880 π s-1
<u>3. Find the A value</u>
we get A value from the given data
A = 0.02 m
By the formula,
y = A sin ( k x – ω t)
Substitute the values we get the equation,
y = 0.02 sin (880π/330 x – 880 πt)
The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)
Answer:
last is the answer.
increase the voltage in order to send energy faster.
