8ft is the ramp that would give you tje most amount of mechanical avantage.
Answer:
T1 = 1/12 x 48 MHz = 4 MHz
Timer’s clock period:
The time delay of one machine cycle is given below. We use this to generate the delay.
T2= 1/ 4000000= 0.25 µ sec
For delay of 10 ms:
1. Firstly divide the desired time delay value (10 ms) by the timer clock period.
N= 1 / 0.25µs
N= 10 ms / 0.25µsec
N=40000
2. Subtract the value of N from the maximum number of counts possible for 16 bit timer i.e. 2^16 = 65536.
M=65536-N
M=65536-40,000
M= 25536

Clock source:
Answer:
a= -0.83m\s^2
Explanation:
a = v \ t
a = -25 \ 30 = -0.833 m\s^2
the object is slowing down 0.83 meter every second
Answer:
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.
Answer:
a long time after the switch is closed
Explanation:
Energy stored in an inductor is given by
E = 1/2 L i²
A). Before the switch is closed the current in the circuit is zero so energy in inductor will be zero.
B). Inductor opposes the flow of current. It takes some time for current to reach its maximum value. So immedialtly after closing the switch the current and energy in inductor will still be zero.
C). After closing the switch it takes some time for current to reach its maximum value as inductor opposes the flow of current. so after a long time the current in inductor will reach its maximum value and hence the energy stored will be maximum.
