C!

V= displacement/time
Speed= distance/time

Displacement is the space between two points, usually from the first to last point, but doesn't have to be. (Basically, it's the distance between your starting and ending point). With displacement, direction matters, but with speed, direction doesn't.

Speed, on the other hand, is the entire traveled distance as a whole. Unlike displacement, direction doesn't matter.

I hope this helped!

I need help with number so can any one help me please and thanks
Inga [223]

Answer:

Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. ... Experiment can provide hints toward the structure or mathematical form of a theory and it can provide evidence for the existence of the entities involved in our theories.

gregori [183]

Answer:

a)  t = 3.027 10⁻⁹ s ,  b)   y = 2.25 10⁻² m

Explanation:

We can solve this problem using the kinematic relations

a) as on the x-axis there is no relationship

          vₓ = x / t

          t = x / vₓ

We reduce the magnitudes to the SI system

          x = 5.6 cm (1m / 100 vm) = 0.056 m

we calculate

          t = 0.056 / 1.85 10⁷

          t = 3.027 10⁻⁹ s

b) the time is the same for the two movements, on the y axis

         y = v₀t + ½ a t²

         

as the beam leaves horizontal there is no initial vertical velocity

         y = ½ a t²

         

let's calculate

         y = ½  5.45 10¹⁵ (3.027 10⁻⁹)²

         y = 2.25 10⁻² m

Which of the following statements does NOT use the term angular size or angular distance correctly?
Verizon [17]

Answer: Statement 1 is incorrect.

Reason:

Unit of measure of angular distance is not meters.

Explanation:

The term 'angular size' is used to describe the apparent size of the objects in the night sky.

The angular distance is defined as the angle through which an object moves on a circular path. The SI unit is radian.

Other units are revolution (rev) and degrees.

In statement 1, angular distance is measured in meters which is incorrect. In other options, there is no factual mistake so they are correct.

Let's discuss them,

Statement 2:

Here, we are talking about the use of outstretched hand to estimate the angular distances and sizes which is correct.

Statement 3:

This statement talks about the same angular sizes of the sun and the moon, here the term is again used correctly.

Statement 4:

Here, the angular distance is measured in the correct units i.e, degrees so this statement is also correct.
