sounds like limestone
Explanation:
but the answer is sedimentary they stick together like cemnt try to remember sedimentary as like cement sedimentary
Answer: The object moves with constant velocity
Explanation:
In this velocity vs time graph we're dealing with Ap physics or regents physics. If we look at the slope we can see it is constant or not changing. Even so lets check the other answers and prove them wrong
The objects speed increases: This is wrong because the line shows a steady 5m/s with no change
The object is in free fall: If the object was in freefall the speed would be increasing as a result of acceleration due to gravity
The object moves with a constant speed: This seems to be the case since the slope or line doesn't change at all
The object stays at rest: Can't be right because the object is at a speed of 5m/s so we know its moving at least
The objects speed decreases: Again the line isn't going up or down so we can't say speed increases or decreases

Answer:
TECHNICIAN B
Explanation: Drive shaft is an elongated part of the drive system made of steel of a vehicle that transmits the <em>ENGINE TORQUE to the WHEELS</em> of a vehicle. For proper inspection a technician is expected to completely remove the driveshaft to check all its compactment. It is Cylindrical and usually used for <em>REAR-WHEEL-VEHICLES</em>. Drive shafts are known by different names like propeller shaft,Cardan shaft etc it has different types which range from
<em>One-piece drive shaft
,Two-piece drive shaft to Slip-in-tube drive shaft
.</em>
Answer:
98%
Explanation:
Given parameters
Mass of motor = 10kg
Height = 2m
Time = 2s
Power input = 100w
Unknown
Efficiency = ?
Solution
Efficiency is the percentage of the power output to the power input.
Power is the rate at which work is done.
Power output = mass x g x height / time
g is the acceleration due to gravity
Power output = 10x 2 x 9.8 / 2 = 98W
Efficiency = power output/ power input x 100
Efficiency = 98/100 x 100 = 98%
