A stone with a mass of 0.700kg is attached to one end of a string 0.600m long. The string will break if its tension exceeds 65.0

belka [17]

Answer:v=7.46 m/s

Explanation:

Given

mass of stone=0.7 kg

Length of string=0.6 m

Maximum tension in string T=65 N

Tension will Provide centripetal force i.e. $\frac{mv^2}{r}$

$T=\frac{mv^2}{r}$

$65=\frac{0.7\times v^2}{0.6}$

$65\times 0.6=0.7\times v^2$

$v^2=\frac{65\times 0.6}{0.7}$

$v^2=55.71$

$v=\sqrt{55.71}=7.46 m/s$

Reflection off of a smooth surface like a mirror is an example of diffuse reflection.

Akimi4 [234]

Answer:

true

Explanation:

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. ... This is called diffuse reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions.

An object moving 20 m/s

yan [13]

Answer:

We are given:

initial velocity (u) = 20m/s

acceleration (a) = 4 m/s²

time (t) = 8 seconds

displacement (s) = s m

Solving for Displacement:

From the seconds equation of motion:

s = ut + 1/2 * at²

replacing the variables

s = 20(8) + 1/2 * (4)*(8)*(8)

s = 160 + 128

s = 288 m
