When a bimetallic bar made of copper and iron strips is heated, it
Sidana [21]

Answer:

The bimetallic strip will bend to the iron's way since

When heated copper expands more than iron

Explanation:

bimetallic strips are temperature regulatory devices used to convert a temperature change into mechanical displacement.

It consists of two layers, usually iron and copper which layers are joined together to form the strip owing to the difference in the constants of expansion of the two materials, a flat strip will bend one way (toward the iron part) if heated. The linear thermal expansion coefficient relates the change in temperature to the change in a material's linear dimensions.

A painter sits on a scaffold that is connected to a rope passing over a pulley. The other end of the rope rests in the hands of
Doss [256]

Solution :

a). From Newtons second law,

F = ma

The total tension force is 2T.

∴ 2T - (m + M)g = (m+ M)a

Then

$a=\frac{2T-(m+M)g}{m+M}$

$a=\frac{2\times 600-(52+63)9.8}{52+63}$

   $=0.63 \ m/s^2$

b). From the person,

   F = ma

 T - Mg + N = Ma

or N = Ma + Mg - T

        = (63 x 9.8) + (52 x 9.8) - 600

        = 617.4 + 509.6 - 600

        = 527 N

1-D catch-up: Two cars move with constant velocities. At t = 0, a blue car is at xBo = 20 m. After t = 4s in the blue car time f
OlgaM077 [116]

Answer:

5.71 m/s ;

20 m/s

Explanation:

Blue car:

At time, t = 0 ; Initial position = 20 m

Final position, = 60m after 4 seconds

The velocity = change in distance / change in time.

Velocity of blue = (60 - 20)m ÷ ((4 + 3) - 0),

Velocity of blue car = 40 / 7

= 5.71 m/s

Red car:

Initial Position = 0 ; final Position = 60

Time taken = 3 seconds

Velocity of Red car = (60 - 0)m ÷ 3

Velocity of Red car = 60 / 3

= 20 m/s
