Let's find the relationship

\\ \rm\Rrightarrow E=h\nu

\\ \rm\Rrightarrow \lambda=\dfrac{c}{\nu}

  • So if frequency increases Energy of the wave increases and wavelength decreases and vice-versa

If a car accelerates from rest at a constant 4 m/s
Readme [11.4K]

Answer:

The time it will take for the car to reach a velocity of 28 m/s is 7 seconds

Explanation:

The parameters of the car are;

The acceleration of the car, a = 4 m/s²

The final velocity of the car, v = 28 m/s

The initial velocity of the car, u = 0 m/s (The car starts from rest)

The kinematic equation that can be used for finding (the time) how long it will take for the car to reach a velocity of 28 m/s is given as follows;

v = u + a·t

Where;

v = The final velocity of the car, v = 28 m/s

u = The initial velocity of the car = 0 m/s

a = The acceleration of the car = 4 m/s²

t = =The time it will take for the car to reach a velocity of 28 m/s

Therefore, we get;

t = (v - u)/a

t = (28 m/s - 0 m/s)/(4 m/s²) = 7 s

The time it will take for the car to reach a velocity of 28 m/s, t = 7 seconds.

1) A plane lands on a runway with a speed of 125 m/s, moving east, and it slows to a stop in 13.0 s. What is the magnitude (in m
valentina_108 [34]

Answer: 1) a = 9.61m/s² pointing to west.

             2) (a) Δv = - 37.9km/s

                  (b) a = - 6.10⁷km/years

Explanation: Aceleration is the change in velocity over change in time.

1) For the plane:

a=\frac{\Delta v}{\Delta t}

a=\frac{125}{13}

a = 9.61m/s²

The plane is moving east, so velocity points in that direction. However, it is stopping at the time of 13s, so acceleration's direction is in the opposite direction. Therefore, acceleration points towards west.

2) Total change of velocity:

\Delta v = v_{f}-v_{i}

\Delta v = -17.1-(+20.8)

\Delta v= -37.9km/s

The interval is in years, so transforming seconds in years:

v = \frac{-37.9}{3.15.10^{-7}}

v=-12.03.10^{7}km/years

Calculating acceleration:

a=\frac{-12.03.10^{-7}}{2.01}

a=-6.10^{7}

Acceleration of an asteroid is a = -6.10⁷km/years .

Which formula can be used to find the tangential speed of an orbiting object?
Luden [163]
The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path

Hope this helps.
