Effectus [21]3 years ago
4 0

Given parameters:

Current of CD player  = 0.1A

Source Voltage = 4V

Unknown:

Resistance  = ?

Solution:

Based on Ohm's law;

           V  = I R;

  V = voltage

   I = current

   R = resistance

Input the parameters and solve;

          4 = 0.1 x R

              R  = \frac{4}{0.1}   = 40ohms

The resistance of the CD player is 40ohms

A 57 kg person in a rollercoaster moving through the bottom of a curved track of radius 42.7 m feels a normal force of 995 N. Ho
natita [175]

Answer:

Use Fc centripetal force as positive and W the weight as negative

N = m v^2 / R + m g

v^2 = (N - m g) R / m

v^2 = (995 - 57 * 9.8) 42.7 / 57 = 327 m^2/s^2

v = 18.1 m/s

Note: N - m g is the net force producing the centripetal force

If an object has a mass of 20 grams and a volume of 40 cm3, what is its density in g/cm3?
sattari [20]
Density = Mass/Volume 
So, given mass = 20 g and volume = 40 cm^3 
By substituting in above equation, Density = 20/40 = 0.5 g/cm^3
Hope it helps.
