Answer:

1800 J

Step-by-step explanation:

At point A when the cart is not in motion, it only has potential energy.

We know that potential energy is given by mgh where m is the mass of the cart, g is acceleration due to gravity and h is the height.

Substituting 12 kg for m, 10 m/s2 for g and 15 m for h then

PE= 12*10*15=1800 J

Answer:

1800

Step-by-step explanation:

P.E. =m.g.h = 12x10x15 = 1800 Joules

K.E/ = 1/2 mv2 = 1/2x12x02 = 0

P.E = 1800 | K.E. 0

M.E. = 1800 + 0 = 1800 Joules

1) The population of a town was7652in 2016. The population grows at a rate of 1.6%annually.(a)Use the exponential growth model t
marshall27 [118]

Answer:

1. a) population of the town in 2024 = 8697

2.) the earthquake with a magnitude of 8 is a <u>100 times stronger</u> than an earthquake with a magnitude of 6.

Step-by-step explanation:

1) the population of a town was, N_{0}   = 7652 in 2016.

a) Exponential growth model is given by N(t) = N_{0} e^{kt} where t is the time in years after 2016.

 Year 2016 is when t = 0.

  k = growth rate constant = 1.6% = 0.016

 i) therefore the population of the town in 2024

    = N = N_{0} e^{kt}  = 7652e^{0.016\times8}  = 8697   ( to the nearest whole number)

2.) log (I \times M \times S) = magnitude of earthquake  where I is the Intensity of the earthquake and S is the intensity of a standard earthquake

therefore  I \times M \times S = 10^{magnitude\hspace{0.1cm}of\hspace{0.1cm}earthquake}

therefore \frac{strength\hspace{0.1cm}of\hspace{0.1cm}earthquake\hspace{0.1cm}1 }{strength\hspace{0.1cm}of\hspace{0.1cm}earthquake\hspace{0.1cm}2}  = \frac{10^{8} }{10^{6} }  = 100
