Answer:
160m/s
Explanation:
The speed of a wave is related to its frequency and wavelength, according to this equation:
v=f ×λ
Answer:
Explanation:
We are given that
Speed of light,v=
Diameter of ring,d=92 m
Radius,r=
Current, I=0.40 A
We have to find the number of electrons in the beam.
We know that
Current,I=
Where q= ne
Using the formula
Answer:
Frequency = 2Hz
Explanation:
In simple harmonic motion,
Frequency is given by the formula;
f = (1/2π)√(k/m))
Where,
k is spring constant and
m is mass
Now, the question says there are 4 suspension springs with each having a spring constant of 47100 N/m. Thus, the total amount of spring constant will be;
K_total = 4 x 47100 N/m = 188,400 N/m
Thus, let's now find the frequency since we have m = 1190kg
f = (1/2π)√(k/m)
f = (1/2π)√(188400/1190)
f = (1/2π) x 12.5825
f = 0.159149 x 12.5825 = 2 Hz
Answer:
The value is
Explanation:
From the question we are told that
The horizontal speed is
The horizontal distance is
Generally the time taken by the hot magma in air before landing is mathematically represented as
=>
=>
Generally the initial vertical velocity of the magma when it was lunched is
Then the final velocity of the magma when it hits the ground is mathematically represented s
Here the negative sign mean that the direction of the velocity is towards the negative y -axis
So
=>
