Answer:
# of Snickers bars 2
Explanation:
Power output= 0.30 HP
=0.3*746
= 0.30 HP (746 W=1.00 HP)
= 224 W
time required 2 h 49 m = 10140 seconds
Since power is work divided by time, then work is:
Work done by the jet = P*t
= 224 *(10140)
= 2.3 MJ (2.3 x 
J)
Converting MJ to Cal
2.3 MJ=549 Cal
# of Snickers bars = 549 Cal / 280 Cal
= 2.0 bars (rounded from 1.96)
Answer:
Janet jumps off a high diving platform with a horizontal velocity of 2.89 m per s and lands in the water 1.5 s later. How high is the platform?
Platform is 11.025 meters high .
Explanation:
we have Vx = 2.89 m/s
time taken = 1.5 seconds
height of the platform = ?
so,
As Janet is jumping from a high diving platform from a certain unknown height their must be involvement of gravity in action.
we can use,
h = Vi*t+(1/2)*g*t^2
where ,
h = height
Vi = initial horizontal velocity that will be zero
t = time in seconds
g = gravity due to acceleration
now put the values
h = 0+(1/2)*(9.8)*(1.5)^2
h = 11.025-m
A. Increase Energy because simple machines are supposed to help humans use less energy and less force when doing a task that normally requires a lot of force and energy
Answer: Technician B
Explanation: A valve overlap occurs when both the exhaust valve and the inlet valve are open at the same time.
It is also seen as the number of degrees at which both the inlet and exhaust valves are open.
Valve overlap helps in boosting the efficiency of the engine by taking advantage of the expelled pressure from the exhaust.
It is expressed mathematically in degrees of shaft rotation.
So, Technician B is very correct.
It makes a cycloid pattern in parametrics if that's what you're asking~
