Answer:
36 grams of water
Explanation:
mass of H2O = 0.5 x 18 = 9g
Answer:
1. 571.43m/s
2. 142.9m and 342.9m
Explanation:
1.Take the difference in time.
1.2-0.7=0.7 seconds
Take the distance between them and divide with differnce in time.
400÷0.7=571.43 seconds.
2.Take the time of the two men and divide by two.
0.5÷2= 0.25 secs
1.2÷2= 0.6 secs
multiply each with the velocity.
0.25×571.43=142.9m
0.6×571.43=342.9m
Answer:
Explanation:
given,
J = 50 kg-m²
frequency, f = 20 Hz
time ,t = 5 s
we know,
angular velocity = 2 π f
ω = 2 π x 20
ω = 125.66 rad/s
now, angular acceleration calculation
α = 25.13 rad/s²
Torque given to the flywheel.
Torque of the given flywheel is equal to
Answer:
Measuring tape
Explanation:
Since we are interested in finding the distance flown by the plane, we would use an instrument measuring length. Since distance flown by the plane is quite significant, a measuring tape is used
