Explanation:
P= rho×g × h (g=10 m/s²) ,
(rho=1000 kg/m³)
P= 1000×10×5= 50,000 N/m² (C)
Dependent / Response Variable: factor or condition in a experiment that changes as a result of the independent variable; often called the responding variable. ... Constant: factors or conditions in an experiment that are kept the same in as trials of the experiment. Control: a set up without the variable being tested.
Answer:
The car that went 54 km in 2/3h was faster, 5/4 times faster than the other car
Explanation:
Average speed of a car is the ratio between the displacement 
and the time (t) it takes to do that displacement:
So, for the first car:
(1)
for the second car we have:
(2)
So, the second cart is faster than the first one. To find how many times divide speed 2 by speed 1:
Answer:
t = 1030 s
Explanation:
Let's start by calculating the resistance of the coil,
V = I (R + ri)
R = V / I - ri
R = 10/10 -0.03
R = 0.97 Ω
Now we can calculate the power supplied to the water
P = I2 R
P = 10 2 0.97
P = 97 w
Work energy is power for time
E = W = P t
t = W / P
t = 100 103/97
t = 1030 s
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation.
