Answer:
A
Explanation:
hydrostatic pressure, P=hρg,
where 'h' is the ht of the liq column and ρ is the density of the liquid and 'g' is the effective acceleration, but as far as hydroSTATICS is concerned, g stands for the acceleration due to gravity
Answer:

Explanation:
The torque applied on an object can be calculated by the following formula:

where,
T = Torque
F = Applied Force
r = radius of the wheel
For car wheel:

For truck wheel:

Dividing both:

for the same force applied on both wheels:

where,
rt = radius of the truck steering wheel = 0.25 m
rc = radius of the car steering wheel = 0.19 m
Therefore,


Answer:
Explanation:
Volume will be largest when x = y = z
area of one face = 100 / 6
= 16.67 cm²
x² = 16.67
x = 4.08 cm
x = y = z = 4.08
Answer:
when you bring two objects of different temperatures together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
