maw [93]

Velocity is displacement/time
(Displacement is the overall change in distance)

So you’ll want to divide 200 by 25, which should give you:

8 m/s

Help needed Can a body be accelerating if it is moving in circle

belka [17]

Answer:

When a body is moving on a circle it is accelerating because centripetal acceleration is always acting on it towards the center.

Please see the attached picture...

From the above diagram,we can say the acceleration is always acting on the body when it moves in a circle.

Hope this helps.......

Good luck on your assignment.......

Katena32 [7]

Answer:

20 m

Explanation:

Initial potential energy = final kinetic energy

mgh = 1/2 mv²

gh = 1/2 v²

h = v² / (2g)

Given v = 20 m/s and g = 10 m/s²:

h = (20 m/s)² / (2 × 10 m/s²)

h = 20 m

When light, starting in air, is shone on a piece of glass, what effects are you likely to observe? a. reflection b. refraction 3

PolarNik [594]

Answer:

refraction

Explanation:

When a ray of light passes from one medium to another medium, it deviates from its path, this phenomenon is called refraction.

When the ray passes from rarer medium to denser medium it bends towards the normal and if the ray passes from denser medium to rarer medium, it bends away from the normal.

Here, the ray passes from air to glass, so refraction takes place.
