Answer:He lifts 2 meters
Explanation:We are trying to find the distance. The formula for distance is W/Force. 50 is our amount of work. 25N is how much force was used. Divide the work bye the force. 50/25=2M
Answer:about 200,000 years ago that humans existed on earth.
Explanation:Geologic time refers to the planet's changing geology. The earliest fossils of modern humans are from the middle Paleolithic about 200,000 years ago such as the omo remains from Ethiopia and the fossil of herto classified equally as homosapiens equally from Ethiopia.
Answer:
if the resistor is fitted in series with the bulb , then the current flowing will be 0.15 A.....
if the resistor if fitted in parallel with the bulb ,
the current flowing will be 0.6 A
Explanation:
total potential difference = 1.5V
when resistors in series ,
total equivalent resistance is = 5 + 5 = 10 ohm
so current = 1.5 ÷ 10 = 0.15
when resistors in parallel ,
total equivalent resistance is = (5 × 5)÷(5 + 5) =2.5 ohm
so current = 1.5÷2.5 = 0.6 A
Answer:
ac = 72 m/s²
Fc = 504 N
Explanation:
We can find the centripetal acceleration of the hammer by using the following formula:
where,
ac = centripetal acceleration = ?
v = constant speed = 12 m/s
r = radius = 2 m
Therefore,
<u>ac = 72 m/s²</u>
<u></u>
Now, the centripetal force applied by the athlete on the hammer will be:
<u>Fc = 504 N</u>
