Highlighter, color coding sections that go together, flash cards, relaxing with someone while they read out questions ( this will help with testing anxiety too). If you get distracted easily use games to study or small sayings instead of the usual white and black sheet of paper.

A window washer drops a brush from a scaffold on a tall office building. What is the speed of the falling brush after 3.28 s? (N
valina [46]

Answer:

The speed of washer will be 32.144 m/s

Explanation:

Given that

time t= 3.28 s

Acceleration due to gravity

 g=9.8\ \frac{m}{s^2}

Here acceleration  is constant so we cam apply the motion equation

we know that

v= u + at

At initial condition  u =0 m/s

v= u + at

v= 0 + 9.8 x 3.28

v= 32.144 m/s

So the speed of washer will be 32.144 m/s

PRACTICE ANOTHERA rabbit is hopping along at an approximately constant speed of 4.2 m/s. The rabbit passes a crouched cat ready
V125BC [204]

Answer:

16.8 seconds

Explanation:

Given that:

Constant speed of rabbit = 4.2 m/s

Initial Velocity (u) of cat = 0

Acceleration (a) of cat = 0.5 m/s²

Time it takes cat to catch rabbit ;

Using the relation:

Distance moved by rabbit (Dr) :

Dr = speed * time ; Dr = 4.2t

Distance moved by Cat (Dc) :

Dc = ut + 0.5at^2

Dc = 0 + 0.5at^2

Hence, Cat will catch rabbit when Dr = Dc

4.2t = 0.5at^2

4.2t = 0.5(0.5)t^2

4.2t = 0.25t^2

Divide both sides by t

4.2 = 0.25t

t = 4.2 / 0.25

t = 16.8 seconds

Hence, the cat will catch the rabbit after 16.8 seconds

The wavelength of 10^15-Hz light is:
Vanyuwa [196]

Answer:

D.300nm

Explanation:

Wavelength = Speed of light / Frequency of light.....

where the speed of light is...(3 × 10^8)

Wavelength = (3 × 10^8)/(1 × 10^15)

Wavelength = 3 × 10^-7

;Wavelength = 300 × 10^-9

Hence its....300 nm
