Answer:
Wave 1 and Wave 2.
Explanation:
We know that the general equation of a wave is given by :
or
We know that the speed of a wave is given by :
Where
= angular speed
k = propagation constant
Wave 1.
Wave 2.
Wave 3.
Wave 4.
It is clear that wave 1 and 2 have the same speed i.e. 7 m/s. Hence, this is the required solution.

We are given the electric field equation so we input all the values we are given, eventually getting E = 51.75 N/C
Answer:
It is due to the large impulse is imparted on the flour.
Explanation:
A ball is moving faster.
When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.
Impulse = change in momentum
So, as the flour experiences large impulse and large momentum so that the flour spreads out.
If the change in momentum is large so the flour spreads out is more.
Answer:
This is your answer. If I'm right so,
Please mark me as brainliest. thanks!!
Higher-level consumers get the most energy from food they eat.
An example is a lion eating a zebra. The zebra has more energy than a handful of grass, which has almost none to offer.
