4 0

Answer:

325 m/s

Explanation:

Frequency of the wave = 250 Hz

wavelength of the wave = 1.3 m

From the wave formula;

v = λf

v = wave speed

λ = wavelength

f= frequency

v = 250 * 1.3 = 325 m/s

Skateboard A Force: 33 N Time: 0. 12 s Skateboard B Force: 33 N Time: 0. 57 s Skateboard C Force: 33 N Time: 0. 78 s Which skate
Snowcat [4.5K]

The skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

From the question,

We are to determine which skateboard has the greatest impulse. To do this, we will calculate the impulse of each skate board.

Impulse can be calculated by using the formula

I = Ft

Where I is the impulse

F is the force

and t is the time

  • For Skateboard A

Force = 33 N

Time = 0. 12 s

∴ Impulse = 33 × 0.12

Impulse  = 3.96 Ns

  • For Skateboard B

Force = 33 N

Time = 0. 57 s

∴ Impulse = 33 × 0.57

Impulse = 18.81 Ns

  • For Skateboard C

Force = 33 N

Time = 0. 78 s

∴ Impulse = 33 × 0.78

Impulse = 25.74 Ns

Hence, the skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

The microwave in your kitchen operates at 2,358,000 Hz. If the speed of light is 300,000,000 m/s, what is the wave’s wavelength?
Novosadov [1.4K]

Answer:

wavelength = speeed / frequency

= 300,000,000 / 2358000

= 300 / 2.358

= 127.2 m
