Which statement is the best description of acceleration?

Physics
1 answer:
elena-s [515]3 years ago
3 0

Answer:

Acceleration is any change in velocity.

Explanation:

Speed is not always changing when accelerating. In fact, when an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. So the correct answer is velocity.

A wave travels at 13 m/s and the crests are 6 meters apart. How many waves would you see pass you by per second? (round up to th
MrRa [10]

Answer:Number of waves =2.2

Explanation:

The frequency of A wave is defined as the number of waves moving  a fixed point per second which is given as

f=\frac{N}{t}

F= Frequency

N= number of waves

t= time

We first find the frequency

Given velocity of the wave, v = 13m/s

and wavelength, λ as 6meters(distance between two consecutive crest)

, we fiind the frequency using

v= f  λ

frequency = v /  λ

= (13m/s ) / 6

=2.16s-1

f =  \frac{N}{t}

2.16s₋¹=  \frac{N}{1s}

Therefore N, Number of waves =  2.16 waves  rounded up to 2.2 waves

A 2-kg block slides along a rough horizontal surface and slows to 10 m/s after traveling 20 m. If the kinetic coefficient of fri
bagirrra123 [75]

Answer:

initial speed is 13.36 m/s

Explanation:

given data

mass = 2 kg

velocity = 10 m/s

distance = 20 m

friction= 0.2

to find out

initial speed

solution

we find first friction force that is

friction force = friction ×mass×g    ...........1

put here value

friction force = 0.2 × 2 × 9.81  

friction force = 3.924 N

here a will be -ve due to friction

- friction force = mass × acceleration

acceleration = - friction force / mass

acceleration = - 3.924 / 2  

acceleration = - 1.962 m/s²

and we know velocity formula that is  

V² = V(i)² + 2as

put here value

10² = V(i)² + 2(-1.962)(20)

V(i) = 13.36  

so initial speed is 13.36 m/s
