Answer to Problem 31P

  36km/(hs)

Explanation of Solution

Given:

The value of acceleration is 1.296×105km/h2 .

Formula used:

Change in velocity within unit time is defined as acceleration.

Write the expression for acceleration.

  a=ΔvΔt

Here, Δv is the change in velocity, Δt is time interval and a is acceleration of object.

SI unit of acceleration is m/s2 ; other unit of acceleration is km/h2 ; 1hr is equal to 3600s .

Calculation:

Convert acceleration from km/h2 to km/(hs) .

  a=(1.296× 105km/ h 2)( 1 km/ ( hs ) 3600 km/ h 2 )=36km/(hs)

Conclusion:

Thus, the value of acceleration is equal to 36km/(hs) .

Answer to Problem 31P

  10m/s2

Explanation of Solution

Given:

The value of acceleration is 1.296×105km/h2 .

Formula used:

Change in velocity within unit time is defined as acceleration.

Write the expression for acceleration.

  a=ΔvΔt

Here, Δv is the change in velocity, Δt is time interval and a is acceleration of object.

SI unit of acceleration is m/s2 ; other unit of acceleration is km/h2 ; 1hr is equal to 3600s ; 1km is equal to 1000m .

Calculation:

Convert acceleration from km/h2 to m/s2 .

  a=(1.296× 105km/ h 2)( 1000 m 1km)( 1h 3600 s)( 1h 3600 s)=10 m/s2

Conclusion:

Thus, the value of acceleration is equal to 10 m/s2 .

Answer to Problem 31P

  88ft/s

Explanation of Solution

Given:

The value of velocity is 60mi/h .

Formula used:

Velocity is defined as total displacement covered within unit time.

Write the expression for velocity.

  v=st

Here, s is the displacement, t is time interval and v is velocity of object.

SI unit of velocity is m/s ; other unit of velocity is

  mi/h and ft/s ; 1hr is equal to 3600s ; 1mi is equal to 5280ft .

Calculation:

Convert velocity from mi/h to ft/s .

  v=(60mi/h)( 5280ft 1 mi)( 1 h 3600 s)=88ft/s

Conclusion:

Thus, the value of velocity is equal to 88ft/s .

Answer to Problem 31P

  26.8m/s .

Explanation of Solution

Given:

The value of velocity is 60mi/h .

Formula used:

Velocity is defined as total displacement covered within unit time.

Write the expression for velocity.

  v=st

Here, s is the displacement, t is time interval and v is velocity of object.

SI unit of velocity is m/s ; other unit of velocity is mi/h and ft/s ; 1hr is equal to 3600s ; 1mi is equal to 1609m .

Calculation:

Convert velocity from mi/h to ft/s .

  v=(60mi/h)( 1609ft 1 mi)( 1 h 3600 s)=26.8m/s

Conclusion:

Thus, the value of velocity is equal to 26.8m/s .

They obtained a positive photoresist, a used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full resist gets developed, and they are unable to transfer the pattern onto the resist. Help them troubleshoot and find out why pattern of transfer has not been successful. 5. You are given a composite…
