Comment on the statement "Sharper the curve, more is the bending." ​
Tatiana [17]

The direction of the angular velocity of the minute hand of a wall-clock is perpendicular to the wall and directed inwards.

The passenger slides away from the centre of the curve.

The angle θ which a cyclist should make with the vertical while taking a circular turn of radius r with velocity v given by

tan θ = v^2/rg

Sharper the curve, smaller is the radius and greater is the value of 0.

Citrus2011 [14]
It looks like you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer generally as the ℓ quantum number increases the energy is slightly higher. As a result 2s and 2p are no longer identical in energy in atoms<span> with more than one electron.</span>


Hope my answer would be a great help for you.    If you have more questions feel free to ask here at Brainly.

A 14,92kw , 400 v , 400 r.p.m . Dc shunt motor draws a current of 40A when running at full-load. The moment of inertia of the ro
Lostsunrise [7]

First we determine the motor's efficiency - a ratio of the mechanical output power and the electrical input power:

E = \frac{P_out}{P_in}=\frac{14920W}{U\cdot I}=\frac{14920W}{400V\cdot 40A}=0.93

The output mechanical power is directly proportional to torque and angular speed. From this relationship we can isolate the torque:

P_{out}=\tau \cdot\omega=E\cdot P_{in}=E\cdot I \cdot U\\\implies\tau = \frac{I \cdot U \cdot E}{\omega}=\frac{I\cdot U\cdot E\cdot 60}{2\pi\cdot \omega_{rpm}}

whereby the last expression uses the angular speed in rpm units.

(a) we calculate the torque, given that the motor draws 1.2 times the rated current, i.e., 48 Amps:

\tau = \frac{I\cdot U\cdot E\cdot 60}{2\pi\cdot \omega_{rpm}}=\frac{48A\cdot 400V\cdot0.93\cdot 60}{2\pi \cdot 400 rpm} = 426.3 Nm

(b) use formula for the acceleration time:

t_{start} = \frac{j\cdot \omega_{rpm}}{\frac{60}{2\pi}\cdot \tau}=\frac{7.5\frac{kg}{m^2}\cdot 400rpm}{9.55\cdot 426.3kg\frac{m^2}{s^2}}\approx 0.74s

The startup time will be 0.74s
