Why didn’t early Portuguese and Dutch explorers decide to create settlements in Australia

aleksandrvk [35]

I think it is because most of the settlements in Australia are under the Spanish rule. Aside from that, Australia was part of the Spanish territory because of the papal bull mandated by Pope Alexander VI. The papal bull divided the world between Spain and Portugal. Spain has full control of the west while Portugal owns the east side of the world

Portuguese explorers were forced to study Australia in secret.

A 100 Ω resistive heater in a tank of water (1kg) increases its temperature from 10°C to 20°C over a period of 1 hour. During th

Nookie1986 [14]

Answer:48.52 kJ

Explanation:

Given

Resistance $=100 \Omega$

temperature increases from $10^{\circ}C to 20^{\circ}C$

Voltage=50 V

Heat given(H) $=\frac{V^2t}{R}$

Where V=voltage applied

t=time

R=Resistance

$H=\frac{50^2\times 60\times 60}{100}=90 kJ$

Heat absorbed by water is

$Q=mc(\Delta T)$

where

m=mass of water

c=specific heat of water

$\Delta T$ =change in temperature

$Q=1000\times 4.184\times (20-10)=41.48 kJ$

Therefore 90-41.48=48.52 kJ is not absorbed by water and leaves the system into the surroundings.

The alarm at a fire station rings and a 87.5-kg fireman, starting from rest, slides down a pole to the floor below (a distance o

blsea [12.9K]

Answer:

$F_f=840N$

Explanation:

From the question we are told that

Weight of fireman $W_f= 87.5kg$

Pole distance $D=4.10m$

Final speed is $V_f 1.75m/s$

Generally the equation for velocity is mathematically represented as

$v^2 = v_0^2 + 2 a d$

Therefore Acceleration a

$a'= v^2 / 2 d$

$a'= 0.21m/s^2$

Generally the equation for Frictional force $F_f$ is mathematically given as

$F_f=m*a$

$F_f=m*(g-0.21)$

$F_f=87.5*(9.81-0.21)$

Therefore

$F_f=840N$
