A. False – The near-side wheels rotate counter-clockwise, but the far-side wheels rotate clockwise.
B. True
C. False – The acute angle is a little more than 60° because by the time the minute hand reaches 10, the hour hand will have moved slightly past the 4.

1.false

1. true
explain - minute hand rotates one hour it takes 360 degree(each gap takes 30 degree) , remaining 1/4 minute takes 90 degree so 360+90=450

3.if 4.00 means in between degree is 60 but 4.10 means ,hour hand slightly move from position .
In hour hand,
60 min=30 degree
1 min=1/2
it past 10 min ,so 10 minutes=5 degree
60+5=65 degree
Ans 3. false
