Answer:

Angle of refraction is 23° .

Explanation:

$\frac{ \sin(0w) }{ \sin(0a) } = \frac{n \: a}{n \: w}$

$\frac{ \sin(30) }{ \sin \: 0a } = \frac{1.3}{1.0}$

$\sin \: 0w \: = \: \frac{ \sin(30) }{1.3}$

$= 0.3846153846$

$\sin^{ - 1} (0.3846153846$

$0w \: = \: 23 ^{o}$

Find the unknown mass of the block 1 needed to balance the bar. Assume that the mass of the bar is negligible. Block 1 is locate

Natasha2012 [34]

Answer:

Incomplete question: The masses of the blocks m₂ = 1.5 kg and m₃ = 2 kg

Explanation:

Given data:

L₁ = length = 0.85 m

L₂ = 0.25 m

L₃ = 0.5 m

m₂ = 1.5 kg

m₃ = 2 kg

Question: Find the unknown mass of the block 1 needed to balance the bar, m₁ = ?

The torque is zero (intermediate point of the bar)

$-m_{1} gL_{1} +m_{2} gL_{2} +m_{3} gL_{3} =0$

Is negative because mass 1 is to the left of the coordinate system (see the diagram)

$m_{1} =\frac{m_{2} gL_{2}+m_{3} gL_{3} }{L_{1} } =\frac{(1.5*0.25)+(2*0.5)}{0.85} =1.6176kg$

1) An average soccer ball has a mass of .4 kg. If a soccer ball is kicked with a force of 750 Newtons, what is the acceleration

Y_Kistochka [10]

Answer:

Explanation:

#1 uses Newton's 2nd Law: F = ma so filling in:

750 = .4a and

a = 1875 m/s/s

#2 uses d = rt so

d = 12.3(25) and

d = 307.5 m
