Answer:
Car A is not accelerating, but car B is accelerating
Explanation:
Car A is not accelerating because , it is moving with uniform speed in a particular direction . Therefore its velocity too is not changing .
But car B is accelerating because , though its speed is uniform but its velocity is changing due to change in direction . On a circular path , direction of speed changes every moment . Therefore it has an acceleration called centripetal acceleration . Hence car B has acceleration.
Answer:
Therefore the amplitude of the resultant wave is 
Explanation:
The equation of wave:
y=A sin (kx-ωt)
For wave 1:
y₁=A sin (kx-ωt) = 
sin (kx-ωt)
For wave 2:
y₂=A sin (kx-ωt+Φ) = sin (kx-ωt+Φ)
Where A= amplitude=
The angular frequency 
, 
= wave length.
t= time
T= Time period
= phase difference = 
The resultant wave will be
y = y₁ + y₂
= sin (kx-ωt) + sin (kx-ωt+Φ)
{sin (kx-ωt) + sin (kx-ωt+Φ)}
Therefore the amplitude of the resultant wave is
I think it may be c, 1.7 v. I work with electricity a lot.
The answer is 1.99 × 10⁻¹⁰ m.
To calculate this we will use De Broglie wavelength formula:
<span>λ = h/(m*v)
</span><span>λ - the wavelength
</span>h - Plank's constant: h = 6.626 × 10⁻³⁴ Js
v - speed
m - mass
It is given:
<span>λ = ?
</span>m = 9.11 × 10⁻²⁸<span> g
v = </span>3.66 × 10⁶<span> m/s
After replacing in the formula:
</span>λ = h/(m*v) = 6.626 × 10⁻³⁴ /(9.11 × 10⁻²⁸ * 3.66 × 10⁶) = 1.99 × 10⁻¹⁰ m
Answer:
Electric field in the membrane is given as
Explanation:
As we know that electric field in a region is related to its potential difference given by the formula
here we know that
so we have
