It should be 0.25kg because you converter from g to kg and since 1g<1kg so you move the decimal to the left
Given: Wavelength λ = 686 nm convert to meter λ = 6.86 x 10⁻⁷ m
Velocity of light c = 3.00 x 10⁸ m/s
Required: Frequency f = ?
Formula: f = c/λ
f = (3.00 x 10⁸ m/s)/(6.86 x 10⁻⁷ m)
f = 4.37 x 10¹⁴ Hz or
f = 437 Terahertz
Answer:
So you can get the results correctly
Answer:
Fa = -Ff provided that the angle between Fa and Ff is zero
Explanation:
Since the net force is zero, the sum of adding all external forces onto the cart must be zero.
Assuming there is no other forces acting on the cart and Fa acting in the same plane as Fc (i.e. zero angle between acting forces),
Fa + Ff = 0
Hence
Fa = -Ff
Answer:
t = 0.85[s]
Explanation:
To solve this problem we must make a complete description of this. By doing an internet search, we find the description of this problem as if of the question.
<u>Description</u>
<u />
"An alligator swims to the left with a constant velocity of 5 m s when the alligator season a bird straight ahead the alligator speeds up with a constant acceleration of 3 m/s^2 leftward until it reaches a final velocity of 35 Ms left work how many seconds does it take the alligator to speed up from 5 m/s to 35 m/s".
To solve this problem we must identify the initial data:
v0 = initial velocity = 5 [m/s]
a = acceleration = 3 [m/s^2]
vf = final velocity = 35[m/s]
t = time = ?
Using the following kinematic equation, we can find the time that is required.
