A pail of water is rotated in a vertical circle of radius r = 1.6 m . The acceleration of gravity is 9.8 m/s 2 . r v What is the
Snowcat [4.5K]

Answer:3.95 m/s

Explanation:

Given

radius of circle r=1.6 m

Water will not spill if the centripetal acceleration is greater than acceleration due to gravity

i.e. a_c\geq g

a_c=\frac{v^2}{r}

\frac{v^2}{r}\geq g

v_{min}=\sqrt{gr}

v_{min}=\sqrt{9.8\times 1.6}

v_{min}=\sqrt{15.68}

v_{min}=3.95 m/s

A 120 V potential difference is applied to a space heater that dissipates 674 W during operation. (a) What is its resistance dur
Annette [7]

Answer:

(a) 21.36 ohms

(b) 5.62 A

Explanation:

Parameters given:

Potential difference, V = 120 V

Power, P = 674 W

(a) Power is given as:

P = V²/R

Where R is resistance

=> R = V²/P

R = 120²/674

R = 14400/674

R = 21.36 ohms

(b) Power is also given as:

P = I*V

Where I = Current (time rate of flow of Electric charge)

=> I = P/V

I = 674/120

I = 5.62 A
