Answer:

D and B.

Explanation:

The wavelength must be taken from the same corresponding point. D and B are both at the crests of a wave, with no other crests in between, which means the distance between them is equal to one wavelength.

Which equation can correctly express the relation between force, acceleration, and mass?

Hi there!

$\large\boxed{\text{a) F = m * a}}$

According to Newton's Second Law, force is calculated with the formula:

F = m × a, where:

F = force (N)

m = mass (kg)

a = acceleration (m/s²)

If a Ferrari, with an initial velocity of 10 m/s,

soldier1979 [14.2K]

Acceleration at 50m/sec² : means every second the velocity increases by 50 m/sec. In 3 seconds the velocity increases by 150 m/s. So total will be 160 m/sec.

the formula is

 V = final velocity = U initial velocity + acceleration a * time duration t

 V = 10 m/s + 50 m/sec² * 3 sec = 160 m/sec

A body moving in the positive x direction passes the origin at time t = 0. Between t=0 and t=1 second, the body has a constant s

The important thing in this type of questions is to keep track of what you are doing at every point.

From t=0 to t=1s, there is uniform motion at v=24 m/s.

Therefore, it will move 24m in that second of time.

Afterwards, an acceleration comes in, so from t=1s to 11s there will be uniformly accelerated motion with acceleration -6m/s^2.

To account for this, you need to use Suvat's equation:

x(t)=x0+v0*t+1/2*a*t^2.

You should know what to plug in for each of the symbols in this equation:

x0 [initial position at t=1s] = 24m
