Answer:
stove
Explanation:
The stove is the independent variable in this question as it does not depend on anything like other variables such as pot, water, temperature and of cause pasta.
The pot depends on the stove, the water depends on the pot and stove, the pasta depends on the water and its temperature.
Cheers.
Answer:
The Required horizontal force is 230.04N
Explanation:
Since the velocity is constant so acceleration is zero; a=0
Now the horizontal force required to move the pickup is equal to the frictional force.
where:
F_{Hn} is the required Force
u is the friction coefficient
m is the mass
g is gravitational acceleration=9.8m/s^2
Eq (1)
Now, weight increases by 42% and friction coefficient decreases by 19%
New weight=(1.42*m*g) and new friction coefficient=0.81u
Eq (2)
Divide Eq(2) and Eq (1)
The Required horizontal force is 230.04N
