Answer:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

If a 42kg rolling object slows from 11.5m/s to 3.33m/s how much work did friction do

geniusboy [140]

Answer: 1608.39 J

Explanation: Given that the

mass M = 42kg

U = 11.5m/s

V = 3.33m/s

how much work did friction do

Work done = Force × distance

Work done = Ma × distance

But acceleration a = V/t

Work done = M × V/t × d

Work done = M × V × d/t

Where d/t = velocity

Therefore,

Work done = M × U × V

Work done = 42 × 11.5 × 3.33

Work done = 1608.39 J

What is speed of light in crown glass?

german

Answer:

1.97 x 10^8 m/s

Explanation:

refractive index of crown glass with respect to air, n = 1.52

speed of light in air, c = 3 x 10^8 m/s

Let v be the speed of light in crown glass.

By use of the definition of refractive index

$n = \frac{c}{v}$

where, n be the refractive index of crown glass, c be the speed of light in vacuum and v be the speed of light in crown glass

$1.52 = \frac{3 \times 10^{8}}{v}$

$v = \frac{3 \times 10^{8}}{1.52}$

v = 1.97 x 10^8 m/s

Thus, the speed of light in crown glass is 1.97 x 10^8 m/s.
