A should be the answer since it makes the water down there cold and the air also. (asked my grandma haha
Answer:0.210 ft/min
Explanation:
Given
Length of trough 
width of base 
height of triangle
From Similar triangles property


volume of water in time t



differentiating

at 



First solve the area of the ow the window os the submarine
A = pi* (0.15)^2= 0.0707 m2
The pressure it can with stand is
P= F/A = 1.2x10^6 N/ 0.0707 m2 = 16976527.26 Pa
Using the formala
P = pgh
Where p is the density of water
G is the accelartion due to gravity
H is the depth
H = P/pg
=16976527.26 Pa/ (1000 kg/m3)(9.81 m/s2)
H = 1730.53 m
The kinetic friction is usually not greater than the applied force. Keep applying more force until you reach a maximum value for the static friction
Answer:
The power of the kettle is P = 1 watt.
Explanation:
The definition of power is:
Power equals the quotient between work and time, or:
P = w/t.
In this case, we know that the work is:
w = 1J
And the time is:
t = 1 s
Then the power will be:
P = 1J/1s = 1 J/s
Also knowing that:
1 J/s = 1 W
(w is the unit for Watt)
We can conclude that the power of the kettle is:
P = 1 W
