What is the trigonometric formula for rotational velocity?
Velocity = Radius x RPM For example if a body of 32 Inches in diameter rotating at 3600 rpm, the velocity is calculated by Velocity = 32/2 * 3600 Velocity = 57,200 inches per minute Velocity = 57,200 Inches/min * 60 Min/Hr * 1ft/12in * 1 mi/5280 ft Velocity = 54.5 miles per hr
How do you calculate initial velocity with time and absorbance as the variables?
Convert the velocity Vmax from ΔA/min to nmol/min (milliunits, mU). For example: 1 Unit = 1 U = 1 μmol PNP formed per min 1 milli-Unit = 1 mU = 1 nmol PNP formed per min Extinction coefficient ε for PNP at 410 nm = 15,000 M-1 cm-1 And the pathlength = 0.34 cm if the velocity v is determined to be 0.294 ∆A/min (absorbance units per min), then: 0.294 ∆A /min * M/(15,000 A * 0.34 cm) = 0.0000196 M/min = 19.6 μM/min = = 19.6 μmol / (liter * min) = 0.0196 μmol / (ml * min) The enzymatic reaction was carried out in 250 μl solution, hence the velocity of the enzyme is 0.0196 μmol / (ml * min) * 0.25 ml = 0.0049 μmol/min = 4.9 nmol/min PNP generated. v = 4.9 nmol/min = 4.9 mU
A train starting from rest attains a velocity of 72Km hr in 5 minutes. Assuming that the acceleration is uniform what is the distance travel by train while attained the velocity?
As the acceleration is uniform, the train has an average speed that is half the difference between the start and final velocities, which in this case is half the final velocity. 1 hr = 60 min 1 km/h = 1 km ÷ 1 hr = km ÷ 60 min = 1/60 km/min Distance = velocity × time = (½ × 72 × 1/60 km/min) × (5 min) = 36/60 × 5 km = 3 km
How many revolutions would a tire make in 45 sec if its anguar velocity were 35 rev min?
There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs
A science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was ms?
He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
Running with an acceleration of 3 m min2 is speeding up 3 m min for every meter traveled True or false?
False. An acceleration of 3 m/min^2 means that the velocity is increasing by 3 m/min for every second traveled, not every meter traveled.
Physics questions- A truck with 0.420m radius tires travels at 32.0m s What is the angular velocity of the rotating tires in radians per second What is this in rev min?
The linear speed of the tire is given by v = Īr, where v is the linear speed, Ī is the angular velocity, and r is the radius. Solving for Ī, we get Ī = v/r = 32.0m/s / 0.420m = 76.2 rad/s. To convert this to rev/min, we use the conversion factor 1 rev = 2Ī radians and 1 min = 60 s, so Ī in rev/min = (76.2 rad/s * 60 s/min) / (2Ī rad/rev) â 726 rev/min.
Evaluate whether the velocity of a jogger can be determined from the information that the jogger travels 2 km in 10 min?
No , because velocity is a vector quantity and it needs direction.
Hoe to calculate velocity of a rotating member?
The velocity of a rotating member can be calculated using the formula v = rĪ, where v is the linear velocity, r is the radius of rotation, and Ī is the angular velocity in radians per second. Multiply the radius of rotation by the angular velocity to find the linear velocity of the rotating member.
What unit is air velocity measured in?
Air velocity is typically measured in units of meters per second (m/s) or feet per minute (ft/min).
