The answer is 0
potential energy= mass• gravity (9.8m/s)• height.
Your mass 3kg. I believe your need to convert this to grams (3000g) and then multiply by 9.8. Since your height is 0 because the ball is on the ground.your potential energy is 0. hope that helped
Answer:
Explanation:
Mass
Diameter
Length
Generally the equation for Volume flow rate is mathematically given by
Generally the equation for Friction factor is mathematically given by
Where Re
Re=Reynolds Number
Therefore
Generally the equation for Friction factor is mathematically given by
Where
A (adenine) - T (Thymine)
C (cytosine) - G (Guanine)
Explanation:
given that the raven flies south for
time= 10 sec
speed= 10km/s
we know that speed=distance/time
distance=speed*time
distance=10*100
distance=1000m
distance=1km
also flies
distance=0.5km = 500m
time= 50 sec
speed= distance/time
speed=500/50
speed= 10m/s
speed= 0.01km/s
The average speed of an object is defined as the distance traveled divided by the time elapsed.
average speed= (1000+500)/10+50
average speed= (1500)/60
average speed= 25m/s
average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s
Answer:
369.84 W
Explanation:
= Mass flow rate = 10.62 kg/s
v = Velocity of wind = 8 m/s
Power is given by
The power supplied is 339.84 W
If 30 W of this power is wasted that means 339.84+30 = 369.84 W is required
